Messages + * containing a `NODE_` prefix in the `cmd` property are reserved for use within + * Node.js core and will not be emitted in the child's `'message'` event. Rather, such messages are emitted using the`'internalMessage'` event and are consumed internally by Node.js. + * Applications should avoid using such messages or listening for`'internalMessage'` events as it is subject to change without notice. + * + * The optional `sendHandle` argument that may be passed to `subprocess.send()` is + * for passing a TCP server or socket object to the child process. The child will + * receive the object as the second argument passed to the callback function + * registered on the `'message'` event. Any data that is received + * and buffered in the socket will not be sent to the child. + * + * The optional `callback` is a function that is invoked after the message is + * sent but before the child may have received it. The function is called with a + * single argument: `null` on success, or an `Error` object on failure. + * + * If no `callback` function is provided and the message cannot be sent, an`'error'` event will be emitted by the `ChildProcess` object. This can + * happen, for instance, when the child process has already exited. + * + * `subprocess.send()` will return `false` if the channel has closed or when the + * backlog of unsent messages exceeds a threshold that makes it unwise to send + * more. Otherwise, the method returns `true`. The `callback` function can be + * used to implement flow control. + * + * #### Example: sending a server object + * + * The `sendHandle` argument can be used, for instance, to pass the handle of + * a TCP server object to the child process as illustrated in the example below: + * + * ```js + * const subprocess = require('child_process').fork('subprocess.js'); + * + * // Open up the server object and send the handle. + * const server = require('net').createServer(); + * server.on('connection', (socket) => { + * socket.end('handled by parent'); + * }); + * server.listen(1337, () => { + * subprocess.send('server', server); + * }); + * ``` + * + * The child would then receive the server object as: + * + * ```js + * process.on('message', (m, server) => { + * if (m === 'server') { + * server.on('connection', (socket) => { + * socket.end('handled by child'); + * }); + * } + * }); + * ``` + * + * Once the server is now shared between the parent and child, some connections + * can be handled by the parent and some by the child. + * + * While the example above uses a server created using the `net` module, `dgram`module servers use exactly the same workflow with the exceptions of listening on + * a `'message'` event instead of `'connection'` and using `server.bind()` instead + * of `server.listen()`. This is, however, currently only supported on Unix + * platforms. + * + * #### Example: sending a socket object + * + * Similarly, the `sendHandler` argument can be used to pass the handle of a + * socket to the child process. The example below spawns two children that each + * handle connections with "normal" or "special" priority: + * + * ```js + * const { fork } = require('child_process'); + * const normal = fork('subprocess.js', ['normal']); + * const special = fork('subprocess.js', ['special']); + * + * // Open up the server and send sockets to child. Use pauseOnConnect to prevent + * // the sockets from being read before they are sent to the child process. + * const server = require('net').createServer({ pauseOnConnect: true }); + * server.on('connection', (socket) => { + * + * // If this is special priority... + * if (socket.remoteAddress === '74.125.127.100') { + * special.send('socket', socket); + * return; + * } + * // This is normal priority. + * normal.send('socket', socket); + * }); + * server.listen(1337); + * ``` + * + * The `subprocess.js` would receive the socket handle as the second argument + * passed to the event callback function: + * + * ```js + * process.on('message', (m, socket) => { + * if (m === 'socket') { + * if (socket) { + * // Check that the client socket exists. + * // It is possible for the socket to be closed between the time it is + * // sent and the time it is received in the child process. + * socket.end(`Request handled with ${process.argv[2]} priority`); + * } + * } + * }); + * ``` + * + * Do not use `.maxConnections` on a socket that has been passed to a subprocess. + * The parent cannot track when the socket is destroyed. + * + * Any `'message'` handlers in the subprocess should verify that `socket` exists, + * as the connection may have been closed during the time it takes to send the + * connection to the child. + * @since v0.5.9 + * @param options The `options` argument, if present, is an object used to parameterize the sending of certain types of handles. `options` supports the following properties: + */ + send(message: Serializable, callback?: (error: Error | null) => void): boolean; + send(message: Serializable, sendHandle?: SendHandle, callback?: (error: Error | null) => void): boolean; + send(message: Serializable, sendHandle?: SendHandle, options?: MessageOptions, callback?: (error: Error | null) => void): boolean; + /** + * Closes the IPC channel between parent and child, allowing the child to exit + * gracefully once there are no other connections keeping it alive.

All +middlewares will populate the `req.body` property with the parsed body when +the `Content-Type` request header matches the `type` option, or an empty +object (`{}`) if there was no body to parse, the `Content-Type` was not matched, +or an error occurred. + +The various errors returned by this module are described in the +[errors section](#errors). + +### bodyParser.json([options]) + +Returns middleware that only parses `json` and only looks at requests where +the `Content-Type` header matches the `type` option. This parser accepts any +Unicode encoding of the body and supports automatic inflation of `gzip` and +`deflate` encodings. + +A new `body` object containing the parsed data is populated on the `request` +object after the middleware (i.e. `req.body`). + +#### Options + +The `json` function takes an optional `options` object that may contain any of +the following keys: + +##### inflate + +When set to `true`, then deflated (compressed) bodies will be inflated; when +`false`, deflated bodies are rejected. Defaults to `true`. + +##### limit + +Controls the maximum request body size. If this is a number, then the value +specifies the number of bytes; if it is a string, the value is passed to the +[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults +to `'100kb'`. + +##### reviver + +The `reviver` option is passed directly to `JSON.parse` as the second +argument. You can find more information on this argument +[in the MDN documentation about JSON.parse](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#Example.3A_Using_the_reviver_parameter). + +##### strict + +When set to `true`, will only accept arrays and objects; when `false` will +accept anything `JSON.parse` accepts. Defaults to `true`. + +##### type + +The `type` option is used to determine what media type the middleware will +parse. This option can be a string, array of strings, or a function. If not a +function, `type` option is passed directly to the +[type-is](https://www.npmjs.org/package/type-is#readme) library and this can +be an extension name (like `json`), a mime type (like `application/json`), or +a mime type with a wildcard (like `*/*` or `*/json`). If a function, the `type` +option is called as `fn(req)` and the request is parsed if it returns a truthy +value. Defaults to `application/json`. + +##### verify + +The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`, +where `buf` is a `Buffer` of the raw request body and `encoding` is the +encoding of the request. The parsing can be aborted by throwing an error. + +### bodyParser.raw([options]) + +Returns middleware that parses all bodies as a `Buffer` and only looks at +requests where the `Content-Type` header matches the `type` option. This +parser supports automatic inflation of `gzip` and `deflate` encodings. + +A new `body` object containing the parsed data is populated on the `request` +object after the middleware (i.e. `req.body`).

The parsing can be aborted by throwing an error. + +### bodyParser.text([options]) + +Returns middleware that parses all bodies as a string and only looks at +requests where the `Content-Type` header matches the `type` option. This +parser supports automatic inflation of `gzip` and `deflate` encodings. + +A new `body` string containing the parsed data is populated on the `request` +object after the middleware (i.e. `req.body`). This will be a string of the +body. + +#### Options + +The `text` function takes an optional `options` object that may contain any of +the following keys: + +##### defaultCharset + +Specify the default character set for the text content if the charset is not +specified in the `Content-Type` header of the request. Defaults to `utf-8`. + +##### inflate + +When set to `true`, then deflated (compressed) bodies will be inflated; when +`false`, deflated bodies are rejected. Defaults to `true`. + +##### limit + +Controls the maximum request body size. If this is a number, then the value +specifies the number of bytes; if it is a string, the value is passed to the +[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults +to `'100kb'`. + +##### type + +The `type` option is used to determine what media type the middleware will +parse. This option can be a string, array of strings, or a function. If not +a function, `type` option is passed directly to the +[type-is](https://www.npmjs.org/package/type-is#readme) library and this can +be an extension name (like `txt`), a mime type (like `text/plain`), or a mime +type with a wildcard (like `*/*` or `text/*`). If a function, the `type` +option is called as `fn(req)` and the request is parsed if it returns a +truthy value. Defaults to `text/plain`. + +##### verify + +The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`, +where `buf` is a `Buffer` of the raw request body and `encoding` is the +encoding of the request. The parsing can be aborted by throwing an error. + +### bodyParser.urlencoded([options]) + +Returns middleware that only parses `urlencoded` bodies and only looks at +requests where the `Content-Type` header matches the `type` option. This +parser accepts only UTF-8 encoding of the body and supports automatic +inflation of `gzip` and `deflate` encodings. + +A new `body` object containing the parsed data is populated on the `request` +object after the middleware (i.e. `req.body`). This object will contain +key-value pairs, where the value can be a string or array (when `extended` is +`false`), or any type (when `extended` is `true`). + +#### Options + +The `urlencoded` function takes an optional `options` object that may contain +any of the following keys: + +##### extended + +The `extended` option allows to choose between parsing the URL-encoded data +with the `querystring` library (when `false`) or the `qs` library (when +`true`). The "extended" syntax allows for rich objects and arrays to be +encoded into the URL-encoded format, allowing for a JSON-like experience +with URL-encoded. For more information, please +[see the qs library](https://www.npmjs.org/package/qs#readme). + +Defaults to `true`, but using the default has been deprecated. Please +research into the difference between `qs` and `querystring` and choose the +appropriate setting. + +##### inflate + +When set to `true`, then deflated (compressed) bodies will be inflated; when +`false`, deflated bodies are rejected. Defaults to `true`. + +##### limit + +Controls the maximum request body size. If this is a number, then the value +specifies the number of bytes; if it is a string, the value is passed to the +[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults +to `'100kb'`. + +##### parameterLimit + +The `parameterLimit` option controls the maximum number of parameters that +are allowed in the URL-encoded data. If a request contains more parameters +than this value, a 413 will be returned to the client. Defaults to `1000`. + +##### type + +The `type` option is used to determine what media type the middleware will +parse. This option can be a string, array of strings, or a function. If not +a function, `type` option is passed directly to the +[type-is](https://www.npmjs.org/package/type-is#readme) library and this can +be an extension name (like `urlencoded`), a mime type (like +`application/x-www-form-urlencoded`), or a mime type with a wildcard (like +`*/x-www-form-urlencoded`). If a function, the `type` option is called as +`fn(req)` and the request is parsed if it returns a truthy value. Defaults +to `application/x-www-form-urlencoded`. + +##### verify + +The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`, +where `buf` is a `Buffer` of the raw request body and `encoding` is the +encoding of the request. The parsing can be aborted by throwing an error. + +## Errors + +The middlewares provided by this module create errors depending on the error +condition during parsing. The errors will typically have a `status`/`statusCode` +property that contains the suggested HTTP response code, an `expose` property +to determine if the `message` property should be displayed to the client, a +`type` property to determine the type of error without matching against the +`message`, and a `body` property containing the read body, if available. + +The following are the common errors emitted, though any error can come through +for various reasons. + +### content encoding unsupported + +This error will occur when the request had a `Content-Encoding` header that +contained an encoding but the "inflation" option was set to `false`. The +`status` property is set to `415`, the `type` property is set to +`'encoding.unsupported'`, and the `charset` property will be set to the +encoding that is unsupported. + +### request aborted + +This error will occur when the request is aborted by the client before reading +the body has finished. The `received` property will be set to the number of +bytes received before the request was aborted and the `expected` property is +set to the number of expected bytes. The `status` property is set to `400` +and `type` property is set to `'request.aborted'`. + +### request entity too large + +This error will occur when the request body's size is larger than the "limit" +option. The `limit` property will be set to the byte limit and the `length` +property will be set to the request body's length. The `status` property is +set to `413` and the `type` property is set to `'entity.too.large'`. + +### request size did not match content length + +This error will occur when the request's length did not match the length from +the `Content-Length` header. This typically occurs when the request is malformed, +typically when the `Content-Length` header was calculated based on characters +instead of bytes. The `status` property is set to `400` and the `type` property +is set to `'request.size.invalid'`. + +### stream encoding should not be set + +This error will occur when something called the `req.setEncoding` method prior +to this middleware. This module operates directly on bytes only and you cannot +call `req.setEncoding` when using this module. The `status` property is set to +`500` and the `type` property is set to `'stream.encoding.set'`. + +### too many parameters + +This error will occur when the content of the request exceeds the configured +`parameterLimit` for the `urlencoded` parser. The `status` property is set to +`413` and the `type` property is set to `'parameters.too.many'`. + +### unsupported charset "BOGUS" + +This error will occur when the request had a charset parameter in the +`Content-Type` header, but the `iconv-lite` module does not support it OR the +parser does not support it. The charset is contained in the message as well +as in the `charset` property. The `status` property is set to `415`, the +`type` property is set to `'charset.unsupported'`, and the `charset` property +is set to the charset that is unsupported. + +### unsupported content encoding "bogus" + +This error will occur when the request had a `Content-Encoding` header that +contained an unsupported encoding. The encoding is contained in the message +as well as in the `encoding` property. The `status` property is set to `415`, +the `type` property is set to `'encoding.unsupported'`, and the `encoding` +property is set to the encoding that is unsupported. + +## Examples + +### Express/Connect top-level generic + +This example demonstrates adding a generic JSON and URL-encoded parser as a +top-level middleware, which will parse the bodies of all incoming requests. +This is the simplest setup. + +```js +var express = require('express') +var bodyParser = require('body-parser') + +var app = express() + +// parse application/x-www-form-urlencoded +app.use(bodyParser.urlencoded({ extended: false })) + +// parse application/json +app.use(bodyParser.json()) + +app.use(function (req, res) { + res.setHeader('Content-Type', 'text/plain') + res.write('you posted:\n') + res.end(JSON.stringify(req.body, null, 2)) +}) +``` + +### Express route-specific + +This example demonstrates adding body parsers specifically to the routes that +need them. In general, this is the most recommended way to use body-parser with +Express. + +```js +var express = require('express') +var bodyParser = require('body-parser') + +var app = express() + +// create application/json parser +var jsonParser = bodyParser.json() + +// create application/x-www-form-urlencoded parser +var urlencodedParser = bodyParser.urlencoded({ extended: false }) + +// POST /login gets urlencoded bodies +app.post('/login', urlencodedParser, function (req, res) { + res.send('welcome, ' + req.body.username) +}) + +// POST /api/users gets JSON bodies +app.post('/api/users', jsonParser, function (req, res) { + // create user in req.body +}) +``` + +### Change accepted type for parsers + +All the parsers accept a `type` option which allows you to change the +`Content-Type` that the middleware will parse. + +```js +var express = require('express') +var bodyParser = require('body-parser') + +var app = express() + +// parse various different custom JSON types as JSON +app.use(bodyParser.json({ type: 'application/*+json' })) + +// parse some custom thing into a Buffer +app.use(bodyParser.raw({ type: 'application/vnd.custom-type' })) + +// parse an HTML body into a string +app.use(bodyParser.text({ type: 'text/html' })) +``` + +## License + +[MIT](LICENSE) + +[npm-image]: https://img.shields.io/npm/v/body-parser.svg +[npm-url]:

require('cookie'); +``` + +### cookie.parse(str, options) + +Parse an HTTP `Cookie` header string and returning an object of all cookie name-value pairs. +The `str` argument is the string representing a `Cookie` header value and `options` is an +optional object containing additional parsing options. + +```js +var cookies = cookie.parse('foo=bar; equation=E%3Dmc%5E2'); +// { foo: 'bar', equation: 'E=mc^2' } +``` + +#### Options + +`cookie.parse` accepts these properties in the options object. + +##### decode + +Specifies a function that will be used to decode a cookie's value. Since the value of a cookie +has a limited character set (and must be a simple string), this function can be used to decode +a previously-encoded cookie value into a JavaScript string or other object. + +The default function is the global `decodeURIComponent`, which will decode any URL-encoded +sequences into their byte representations. + +**note** if an error is thrown from this function, the original, non-decoded cookie value will +be returned as the cookie's value. + +### cookie.serialize(name, value, options) + +Serialize a cookie name-value pair into a `Set-Cookie` header string. The `name` argument is the +name for the cookie, the `value` argument is the value to set the cookie to, and the `options` +argument is an optional object containing additional serialization options. + +```js +var setCookie = cookie.serialize('foo', 'bar'); +// foo=bar +``` + +#### Options + +`cookie.serialize` accepts these properties in the options object. + +##### domain + +Specifies the value for the [`Domain` `Set-Cookie` attribute][rfc-6265-5.2.3]. By default, no +domain is set, and most clients will consider the cookie to apply to only the current domain. + +##### encode + +Specifies a function that will be used to encode a cookie's value. Since value of a cookie +has a limited character set (and must be a simple string), this function can be used to encode +a value into a string suited for a cookie's value. + +The default function is the global `encodeURIComponent`, which will encode a JavaScript string +into UTF-8 byte sequences and then URL-encode any that fall outside of the cookie range. + +##### expires + +Specifies the `Date` object to be the value for the [`Expires` `Set-Cookie` attribute][rfc-6265-5.2.1]. +By default, no expiration is set, and most clients will consider this a "non-persistent cookie" and +will delete it on a condition like exiting a web browser application. + +**note** the [cookie storage model specification][rfc-6265-5.3] states that if both `expires` and +`maxAge` are set, then `maxAge` takes precedence, but it is possible not all clients by obey this, +so if both are set, they should point to the same date and time. + +##### httpOnly + +Specifies the `boolean` value for the [`HttpOnly` `Set-Cookie` attribute][rfc-6265-5.2.6]. When truthy, +the `HttpOnly` attribute is set, otherwise it is not. By default, the `HttpOnly` attribute is not set. + +**note** be careful when setting this to `true`, as compliant clients will not allow client-side +JavaScript to see the cookie in `document.cookie`. + +##### maxAge + +Specifies the `number` (in seconds) to be the value for the [`Max-Age` `Set-Cookie` attribute][rfc-6265-5.2.2]. +The given number will be converted to an integer by rounding down. By default, no maximum age is set. + +**note** the [cookie storage model specification][rfc-6265-5.3] states that if both `expires` and +`maxAge` are set, then `maxAge` takes precedence, but it is possible not all clients by obey this, +so if both are set, they should point to the same date and time. + +##### path + +Specifies the value for the [`Path` `Set-Cookie` attribute][rfc-6265-5.2.4]. By default, the path +is considered the ["default path"][rfc-6265-5.1.4]. + +##### sameSite + +Specifies the `boolean` or `string` to be the value for the [`SameSite` `Set-Cookie` attribute][rfc-6265bis-03-4.1.2.7]. + + - `true` will set the `SameSite` attribute to `Strict` for strict same site enforcement. + - `false` will not set the `SameSite` attribute. + - `'lax'` will set the `SameSite` attribute to `Lax` for lax same site enforcement. + - `'none'` will set the `SameSite` attribute to `None` for an explicit cross-site cookie. + - `'strict'` will set the `SameSite` attribute to `Strict` for strict same site enforcement. + +More information about the different enforcement levels can be found in +[the specification][rfc-6265bis-03-4.1.2.7]. + +**note** This is an attribute that has not yet been fully standardized, and may change in the future. +This also means many clients may ignore this attribute until they understand it. + +##### secure + +Specifies the `boolean` value for the [`Secure` `Set-Cookie` attribute][rfc-6265-5.2.5]. When truthy, +the `Secure` attribute is set, otherwise it is not. By default, the `Secure` attribute is not set. + +**note** be careful when setting this to `true`, as compliant clients will not send the cookie back to +the server in the future if the browser does not have an HTTPS connection. + +## Example + +The following example uses this module in conjunction with the Node.js core HTTP server +to prompt a user for their name and display it back on future visits. + +```js +var cookie = require('cookie'); +var escapeHtml = require('escape-html'); +var http = require('http'); +var url = require('url'); + +function onRequest(req, res) { + // Parse the query string + var query = url.parse(req.url, true, true).query; + + if (query && query.name) { + // Set a new cookie with the name + res.setHeader('Set-Cookie', cookie.serialize('name', String(query.name), { + httpOnly: true, + maxAge: 60 * 60 * 24 * 7 // 1 week + })); + + // Redirect back after setting cookie + res.statusCode = 302; + res.setHeader('Location', req.headers.referer || '/'); + res.end(); + return; + } + + // Parse the cookies on the request + var cookies = cookie.parse(req.headers.cookie || ''); + + // Get the visitor name set in the cookie + var name = cookies.name; + + res.setHeader('Content-Type', 'text/html; charset=UTF-8'); + + if (name) { + res.write('

This will allow you to toggle the debug output for different parts of your module as well as the module as a whole. + +Example _app.js_: + +```js +var debug = require('debug')('http') + , http = require('http') + , name = 'My App'; + +// fake app + +debug('booting %s', name); + +http.createServer(function(req, res){ + debug(req.method + ' ' + req.url); + res.end('hello\n'); +}).listen(3000, function(){ + debug('listening'); +}); + +// fake worker of some kind + +require('./worker'); +``` + +Example _worker.js_: + +```js +var debug = require('debug')('worker'); + +setInterval(function(){ + debug('doing some work'); +}, 1000); +``` + + The __DEBUG__ environment variable is then used to enable these based on space or comma-delimited names. Here are some examples: + + ![debug http and worker](http://f.cl.ly/items/18471z1H402O24072r1J/Screenshot.png) + + ![debug worker](http://f.cl.ly/items/1X413v1a3M0d3C2c1E0i/Screenshot.png) + +#### Windows note + + On Windows the environment variable is set using the `set` command. + + ```cmd + set DEBUG=*,-not_this + ``` + + Note that PowerShell uses different syntax to set environment variables. + + ```cmd + $env:DEBUG = "*,-not_this" + ``` + +Then, run the program to be debugged as usual. + +## Millisecond diff + + When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls. + + ![](http://f.cl.ly/items/2i3h1d3t121M2Z1A3Q0N/Screenshot.png) + + When stdout is not a TTY, `Date#toUTCString()` is used, making it more useful for logging the debug information as shown below: + + ![](http://f.cl.ly/items/112H3i0e0o0P0a2Q2r11/Screenshot.png) + +## Conventions + + If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser". + +## Wildcards + + The `*` character may be used as a wildcard. Suppose for example your library has debuggers named "connect:bodyParser", "connect:compress", "connect:session", instead of listing all three with `DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do `DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`. + + You can also exclude specific debuggers by prefixing them with a "-" character. For example, `DEBUG=*,-connect:*` would include all debuggers except those starting with "connect:". + +## Environment Variables + + When running through Node.js, you can set a few environment variables that will + change the behavior of the debug logging: + +| Name | Purpose | +|-----------|-------------------------------------------------| +| `DEBUG` | Enables/disables specific debugging namespaces. | +| `DEBUG_COLORS`| Whether or not to use colors in the debug output. | +| `DEBUG_DEPTH` | Object inspection depth. | +| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. | + + + __Note:__ The environment variables beginning with `DEBUG_` end up being + converted into an Options object that gets used with `%o`/`%O` formatters. + See the Node.js documentation for + [`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options) + for the complete list. + +## Formatters + + + Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting. Below are the officially supported formatters: + +| Formatter | Representation | +|-----------|----------------| +| `%O` | Pretty-print an Object on multiple lines. | +| `%o` | Pretty-print an Object all on a single line. | +| `%s` | String. | +| `%d` | Number (both integer and float). | +| `%j` | JSON. Replaced with the string '[Circular]' if the argument contains circular references. | +| `%%` | Single percent sign ('%'). This does not consume an argument. | + +### Custom formatters + + You can add custom formatters by extending the `debug.formatters` object. For example, if you wanted to add support for rendering a Buffer as hex with `%h`, you could do something like: + +```js +const createDebug = require('debug') +createDebug.formatters.h = (v) => { + return v.toString('hex') +} + +// …elsewhere +const debug = createDebug('foo') +debug('this is hex: %h', new Buffer('hello world')) +// foo this is hex: 68656c6c6f20776f726c6421 +0ms +``` + +## Browser support + You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify), + or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest), + if you don't want to build it yourself. + + Debug's enable state is currently persisted by `localStorage`. + Consider the situation shown below where you have `worker:a` and `worker:b`, + and wish to debug both. You can enable this using `localStorage.debug`: + +```js +localStorage.debug = 'worker:*' +``` + +And then refresh the page. + +```js +a = debug('worker:a'); +b = debug('worker:b'); + +setInterval(function(){ + a('doing some work'); +}, 1000); + +setInterval(function(){ + b('doing some work'); +}, 1200); +``` + +#### Web Inspector Colors + + Colors are also enabled on "Web Inspectors" that understand the `%c` formatting + option. These are WebKit web inspectors, Firefox ([since version + 31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/)) + and the Firebug plugin for Firefox (any version). + + Colored output looks something like: + + ![](https://cloud.githubusercontent.com/assets/71256/3139768/b98c5fd8-e8ef-11e3-862a-f7253b6f47c6.png) + + +## Output streams + + By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method: + +Example _stdout.js_: + +```js +var debug = require('debug'); +var error = debug('app:error'); + +// by default stderr is used +error('goes to stderr!'); + +var log = debug('app:log'); +// set this namespace to log via console.log +log.log = console.log.bind(console); // don't forget to bind to console! +log('goes to stdout'); +error('still goes to stderr!'); + +// set all output to go via console.info +// overrides all per-namespace log settings +debug.log = console.info.bind(console); +error('now goes to stdout via console.info'); +log('still goes to stdout, but via console.info now'); +``` + + +## Authors + + - TJ Holowaychuk + - Nathan Rajlich + - Andrew Rhyne + +## Backers + +Support us with a monthly donation and help us continue our activities.

+[Browserify](http://browserify.org/) or [webpack](https://webpack.github.io/), +though by default this module will alter it's API to no longer display or +track deprecations. + +## API + + + +```js +var deprecate = require('depd')('my-module') +``` + +This library allows you to display deprecation messages to your users. +This library goes above and beyond with deprecation warnings by +introspection of the call stack (but only the bits that it is interested +in). + +Instead of just warning on the first invocation of a deprecated +function and never again, this module will warn on the first invocation +of a deprecated function per unique call site, making it ideal to alert +users of all deprecated uses across the code base, rather than just +whatever happens to execute first. + +The deprecation warnings from this module also include the file and line +information for the call into the module that the deprecated function was +in. + +**NOTE** this library has a similar interface to the `debug` module, and +this module uses the calling file to get the boundary for the call stacks, +so you should always create a new `deprecate` object in each file and not +within some central file. + +### depd(namespace) + +Create a new deprecate function that uses the given namespace name in the +messages and will display the call site prior to the stack entering the +file this function was called from. It is highly suggested you use the +name of your module as the namespace. + +### deprecate(message) + +Call this function from deprecated code to display a deprecation message. +This message will appear once per unique caller site. Caller site is the +first call site in the stack in a different file from the caller of this +function. + +If the message is omitted, a message is generated for you based on the site +of the `deprecate()` call and will display the name of the function called, +similar to the name displayed in a stack trace. + +### deprecate.function(fn, message) + +Call this function to wrap a given function in a deprecation message on any +call to the function. An optional message can be supplied to provide a custom +message. + +### deprecate.property(obj, prop, message) + +Call this function to wrap a given property on object in a deprecation message +on any accessing or setting of the property. An optional message can be supplied +to provide a custom message. + +The method must be called on the object where the property belongs (not +inherited from the prototype). + +If the property is a data descriptor, it will be converted to an accessor +descriptor in order to display the deprecation message. + +### process.on('deprecation', fn) + +This module will allow easy capturing of deprecation errors by emitting the +errors as the type "deprecation" on the global `process`. If there are no +listeners for this type, the errors are written to STDERR as normal, but if +there are any listeners, nothing will be written to STDERR and instead only +emitted. From there, you can write the errors in a different format or to a +logging source. + +The error represents the deprecation and is emitted only once with the same +rules as writing to STDERR. The error has the following properties: + + - `message` - This is the message given by the library + - `name` - This is always `'DeprecationError'` + - `namespace` - This is the namespace the deprecation came from + - `stack` - This is the stack of the call to the deprecated thing + +Example `error.stack` output: + +``` +DeprecationError: my-cool-module deprecated oldfunction + at Object. ([eval]-wrapper:6:22) + at Module._compile (module.js:456:26) + at evalScript (node.js:532:25) + at startup (node.js:80:7) + at node.js:902:3 +``` + +### process.env.NO_DEPRECATION + +As a user of modules that are deprecated, the environment variable `NO_DEPRECATION` +is provided as a quick solution to silencing deprecation warnings from being +output. The format of this is similar to that of `DEBUG`: + +```sh +$ NO_DEPRECATION=my-module,othermod node app.js +``` + +This will suppress deprecations from being output for "my-module" and "othermod". +The value is a list of comma-separated namespaces. To suppress every warning +across all namespaces, use the value `*` for a namespace. + +Providing the argument `--no-deprecation` to the `node` executable will suppress +all deprecations (only available in Node.js 0.8 or higher). + +**NOTE** This will not suppress the deperecations given to any "deprecation" +event listeners, just the output to STDERR. + +### process.env.TRACE_DEPRECATION + +As a user of modules that are deprecated, the environment variable `TRACE_DEPRECATION` +is provided as a solution to getting more detailed location information in deprecation +warnings by including the entire stack trace. The format of this is the same as +`NO_DEPRECATION`: + +```sh +$ TRACE_DEPRECATION=my-module,othermod node app.js +``` + +This will include stack traces for deprecations being output for "my-module" and +"othermod". The value is a list of comma-separated namespaces. To trace every +warning across all namespaces, use the value `*` for a namespace. + +Providing the argument `--trace-deprecation` to the `node` executable will trace +all deprecations (only available in Node.js 0.8 or higher). + +**NOTE** This will not trace the deperecations silenced by `NO_DEPRECATION`. + +## Display + +![message](files/message.png) + +When a user calls a function in your library that you mark deprecated, they +will see the following written to STDERR (in the given colors, similar colors +and layout to the `debug` module): + +``` +bright cyan bright yellow +| | reset cyan +| | | | +▼ ▼ ▼ ▼ +my-cool-module deprecated oldfunction [eval]-wrapper:6:22 +▲ ▲ ▲ ▲ +| | | | +namespace | | location of mycoolmod.oldfunction() call + | deprecation message + the word "deprecated" +``` + +If the user redirects their STDERR to a file or somewhere that does not support +colors, they see (similar layout to the `debug` module): + +``` +Sun, 15 Jun 2014 05:21:37 GMT my-cool-module deprecated oldfunction at [eval]-wrapper:6:22 +▲ ▲ ▲ ▲ ▲ +| | | | | +timestamp of message namespace | | location of mycoolmod.oldfunction() call + | deprecation message + the word "deprecated" +``` + +## Examples + +### Deprecating all calls to a function + +This will display a deprecated message about "oldfunction" being deprecated +from "my-module" on STDERR. + +```js +var deprecate = require('depd')('my-cool-module') + +// message automatically derived from function name +// Object.oldfunction +exports.oldfunction = deprecate.function(function oldfunction () { + // all calls to function are deprecated +}) + +// specific message +exports.oldfunction = deprecate.function(function () { + // all calls to function are deprecated +}, 'oldfunction') +``` + +### Conditionally deprecating a function call + +This will display a deprecated message about "weirdfunction" being deprecated +from "my-module" on STDERR when called with less than 2 arguments. + +```js +var deprecate = require('depd')('my-cool-module') + +exports.weirdfunction = function () { + if (arguments.length < 2) { + // calls with 0 or 1 args are deprecated + deprecate('weirdfunction args < 2') + } +} +``` + +When calling `deprecate` as a function, the warning is counted per call site +within your own module, so you can display different deprecations depending +on different situations and the users will still get all the warnings: + +```js +var deprecate = require('depd')('my-cool-module') + +exports.weirdfunction = function () { + if (arguments.length < 2) { + // calls with 0 or 1 args are deprecated + deprecate('weirdfunction args < 2') + } else if (typeof arguments[0] !== 'string') { + // calls with non-string first argument are deprecated + deprecate('weirdfunction non-string first arg') + } +} +``` + +### Deprecating property access + +This will display a deprecated message about "oldprop" being deprecated +from "my-module" on STDERR when accessed. A deprecation will be displayed +when setting the value and when getting the value. + +```js +var deprecate = require('depd')('my-cool-module') + +exports.oldprop = 'something' + +// message automatically derives from property name +deprecate.property(exports, 'oldprop') + +// explicit message +deprecate.property(exports, 'oldprop', 'oldprop >= 0.10') +``` + +## License + +[MIT](LICENSE)

If `err` is falsy, the handler will +write out a 404 response to the `res`. If it is truthy, an error response will +be written out to the `res`. + +When an error is written, the following information is added to the response: + + * The `res.statusCode` is set from `err.status` (or `err.statusCode`). If + this value is outside the 4xx or 5xx range, it will be set to 500. + * The `res.statusMessage` is set according to the status code. + * The body will be the HTML of the status code message if `env` is + `'production'`, otherwise will be `err.stack`. + * Any headers specified in an `err.headers` object. + +The final handler will also unpipe anything from `req` when it is invoked. + +#### options.env + +By default, the environment is determined by `NODE_ENV` variable, but it can be +overridden by this option. + +#### options.onerror + +Provide a function to be called with the `err` when it exists. Can be used for +writing errors to a central location without excessive function generation.

The module +[jumanji](https://www.npmjs.com/package/jumanji) can be used in +an Express application to work-around this issue and also provides +links to further reading on this Safari bug. + +## Example + +### API usage + + + +```js +var reqHeaders = { 'if-none-match': '"foo"' } +var resHeaders = { 'etag': '"bar"' } +fresh(reqHeaders, resHeaders) +// => false + +var reqHeaders = { 'if-none-match': '"foo"' } +var resHeaders = { 'etag': '"foo"' } +fresh(reqHeaders, resHeaders) +// => true +``` + +### Using with Node.js http server + +```js +var fresh = require('fresh') +var http = require('http') + +var server = http.createServer(function (req, res) { + // perform server logic + // ... including adding ETag / Last-Modified response headers + + if (isFresh(req, res)) { + // client has a fresh copy of resource + res.statusCode = 304 + res.end() + return + } + + // send the resource + res.statusCode = 200 + res.end('hello, world!') +}) + +function isFresh (req, res) { +

It runs on both CommonJS runtimes +(e.g. [nodejs]) and in a web browser. + +ipaddr.js allows you to verify and parse string representation of an IP +address, match it against a CIDR range or range list, determine if it falls +into some reserved ranges (examples include loopback and private ranges), +and convert between IPv4 and IPv4-mapped IPv6 addresses. + +[nodejs]: http://nodejs.org + +## Installation + +`npm install ipaddr.js` + +or + +`bower install ipaddr.js` + +## API + +ipaddr.js defines one object in the global scope: `ipaddr`. In CommonJS, +it is exported from the module: + +```js +var ipaddr = require('ipaddr.js'); +``` + +The API consists of several global methods and two classes: ipaddr.IPv6 and ipaddr.IPv4. + +### Global methods + +There are three global methods defined: `ipaddr.isValid`, `ipaddr.parse` and +`ipaddr.process`. All of them receive a string as a single parameter. + +The `ipaddr.isValid` method returns `true` if the address is a valid IPv4 or +IPv6 address, and `false` otherwise. It does not throw any exceptions. + +The `ipaddr.parse` method returns an object representing the IP address, +or throws an `Error` if the passed string is not a valid representation of an +IP address. + +The `ipaddr.process` method works just like the `ipaddr.parse` one, but it +automatically converts IPv4-mapped IPv6 addresses to their IPv4 counterparts +before returning. It is useful when you have a Node.js instance listening +on an IPv6 socket, and the `net.ivp6.bindv6only` sysctl parameter (or its +equivalent on non-Linux OS) is set to 0. In this case, you can accept IPv4 +connections on your IPv6-only socket, but the remote address will be mangled. +Use `ipaddr.process` method to automatically demangle it. + +### Object representation + +Parsing methods return an object which descends from `ipaddr.IPv6` or +`ipaddr.IPv4`. These objects share some properties, but most of them differ. + +#### Shared properties + +One can determine the type of address by calling `addr.kind()`. It will return +either `"ipv6"` or `"ipv4"`. + +An address can be converted back to its string representation with `addr.toString()`. +Note that this method: + * does not return the original string used to create the object (in fact, there is + no way of getting that string) + * returns a compact representation (when it is applicable) + +A `match(range, bits)` method can be used to check if the address falls into a +certain CIDR range. +Note that an address can be (obviously) matched only against an address of the same type. + +For example: + +```js +var addr = ipaddr.parse("2001:db8:1234::1"); +var range = ipaddr.parse("2001:db8::"); + +addr.match(range, 32); // => true +``` + +Alternatively, `match` can also be called as `match([range, bits])`. In this way, +it can be used together with the `parseCIDR(string)` method, which parses an IP +address together with a CIDR range. + +For example: + +```js +var addr = ipaddr.parse("2001:db8:1234::1"); + +addr.match(ipaddr.parseCIDR("2001:db8::/32")); // => true +``` + +A `range()` method returns one of predefined names for several special ranges defined +by IP protocols. The exact names (and their respective CIDR ranges) can be looked up +in the source: [IPv6 ranges] and [IPv4 ranges]. Some common ones include `"unicast"` +(the default one) and `"reserved"`. + +You can match against your own range list by using +`ipaddr.subnetMatch(address, rangeList, defaultName)` method. It can work with a mix of IPv6 or IPv4 addresses, and accepts a name-to-subnet map as the range list. For example: + +```js +var rangeList = { + documentationOnly: [ ipaddr.parse('2001:db8::'), 32 ], + tunnelProviders: [ + [ ipaddr.parse('2001:470::'), 32 ], // he.net + [ ipaddr.parse('2001:5c0::'), 32 ] // freenet6 + ] +}; +ipaddr.subnetMatch(ipaddr.parse('2001:470:8:66::1'), rangeList, 'unknown'); // => "tunnelProviders" +``` + +The addresses can be converted to their byte representation with `toByteArray()`. +(Actually, JavaScript mostly does not know about byte buffers. They are emulated with +arrays of numbers, each in range of 0..255.) + +```js +var bytes = ipaddr.parse('2a00:1450:8007::68').toByteArray(); // ipv6.google.com +bytes // => [42, 0x00, 0x14, 0x50, 0x80, 0x07, 0x00, , 0x00, 0x68 ] +``` + +The `ipaddr.IPv4` and `ipaddr.IPv6` objects have some methods defined, too. All of them +have the same interface for both protocols, and are similar to global methods. + +`ipaddr.IPvX.isValid(string)` can be used to check if the string is a valid address +for particular protocol, and `ipaddr.IPvX.parse(string)` is the error-throwing parser. + +`ipaddr.IPvX.isValid(string)` uses the same format for parsing as the POSIX `inet_ntoa` function, which accepts unusual formats like `0xc0.168.1.1` or `0x10000000`. The function `ipaddr.IPv4.isValidFourPartDecimal(string)` validates the IPv4 address and also ensures that it is written in four-part decimal format. + +[IPv6 ranges]: https://github.com/whitequark/ipaddr.js/blob/master/src/ipaddr.coffee#L186 +[IPv4 ranges]: https://github.com/whitequark/ipaddr.js/blob/master/src/ipaddr.coffee#L71 + +#### IPv6 properties + +Sometimes you will want to convert IPv6 not to a compact string representation (with +the `::` substitution); the `toNormalizedString()` method will return an address where +all zeroes are explicit. + +For example: + +```js +var addr = ipaddr.parse("2001:0db8::0001"); +addr.toString(); // => "2001:db8::1" +addr.toNormalizedString(); // => "2001:db8:0:0:0:0:0:1" +``` + +The `isIPv4MappedAddress()` method will return `true` if this address is an IPv4-mapped +one, and `toIPv4Address()` will return an IPv4 object address. + +To access the underlying binary representation of the address, use `addr.parts`. + +```js +var addr = ipaddr.parse("2001:db8:10::1234:DEAD"); +addr.parts // => [0x2001, 0xdb8, 0x10, 0, 0, 0, 0x1234, 0xdead] +``` + +A IPv6 zone index can be accessed via `addr.zoneId`: + +```js +var addr = ipaddr.parse("2001:db8::%eth0"); +addr.zoneId // => 'eth0' +``` + +#### IPv4 properties + +`toIPv4MappedAddress()` will return a corresponding IPv4-mapped IPv6 address. + +To access the underlying representation of the address, use `addr.octets`. + +```js +var addr = ipaddr.parse("192.168.1.1"); +addr.octets // => [192, 168, 1, 1] +``` + +`prefixLengthFromSubnetMask()` will return a CIDR prefix length for a valid IPv4 netmask or +null if the netmask is not valid. + +```js +ipaddr.IPv4.parse('255.255.255.240').prefixLengthFromSubnetMask() == 28 +ipaddr.IPv4.parse('255.192.164.0').prefixLengthFromSubnetMask() == null +``` + +`subnetMaskFromPrefixLength()` will return an IPv4 netmask for a valid CIDR prefix length. + +```js +ipaddr.IPv4.subnetMaskFromPrefixLength(24) == "255.255.255.0" +ipaddr.IPv4.subnetMaskFromPrefixLength(29) == "255.255.255.248" +``` + +`broadcastAddressFromCIDR()` will return the broadcast address for a given IPv4 interface and netmask in CIDR notation. +```js +ipaddr.IPv4.broadcastAddressFromCIDR("172.0.0.1/24") == "172.0.0.255" +``` +`networkAddressFromCIDR()` will return the network address for a given IPv4 interface and netmask in CIDR notation. +```js +ipaddr.IPv4.networkAddressFromCIDR("172.0.0.1/24") == "172.0.0.0" +``` + +#### Conversion + +IPv4 and IPv6 can be converted bidirectionally to and from network byte order (MSB) byte arrays. + +The `fromByteArray()` method will take an array and create an appropriate IPv4 or IPv6 object +if the input satisfies the requirements.

This needs to be a [primary source](https://en.wikipedia.org/wiki/Primary_source); + links to type aggregating sites and Wikipedia are _not acceptable_. + +To update the build, run `npm run build`. + +### Adding Custom Media Types + +The best way to get new media types included in this library is to register +them with the IANA. The community registration procedure is outlined in +[RFC 6838 section 5](http://tools.ietf.org/html/rfc6838#section-5). Types +registered with the IANA are automatically pulled into this library. + +If that is not possible / feasible, they can be added directly here as a +"custom" type. To do this, it is required to have a primary source that +definitively lists the media type. If an extension is going to be listed as +associateed with this media type, the source must definitively link the +media type and extension as well. + +[ci-image]:

Please do not email any of the driver developers directly with issues or questions - you're more likely to get an answer on the [MongoDB Community Forums](https://community.mongodb.com/tags/c/drivers-odms-connectors/7/node-js-driver). + +### Change Log + +Change history can be found in [`HISTORY.md`](https://github.com/mongodb/node-mongodb-native/blob/4.0/HISTORY.md). + +### Compatibility + +For version compatibility matrices, please refer to the following links: + +- [MongoDB](https://docs.mongodb.com/drivers/node/compatibility#mongodb-compatibility) +- [NodeJS](https://docs.mongodb.com/drivers/node/compatibility#language-compatibility) + +#### Typescript Version + +We recommend using the latest version of typescript, however we do provide a [downleveled](https://github.com/sandersn/downlevel-dts#readme) version of the type definitions that we test compiling against `typescript@4.0.2`. +Since typescript [does not restrict breaking changes to major versions](https://github.com/Microsoft/TypeScript/wiki/Breaking-Changes) we consider this support best effort. +If you run into any unexpected compiler failures please let us know and we will do our best to correct it. + +## Installation + +The recommended way to get started using the Node.js 4.0 driver is by using the `npm` (Node Package Manager) to install the dependency in your project. + +After you've created your own project using `npm init`, you can run: + +```bash +npm install mongodb +# or ... +yarn add mongodb +``` + +This will download the MongoDB driver and add a dependency entry in your `package.json` file. + +## Troubleshooting + +The MongoDB driver depends on several other packages. These are: + +- [bson](https://github.com/mongodb/js-bson) +- [bson-ext](https://github.com/mongodb-js/bson-ext) +- [kerberos](https://github.com/mongodb-js/kerberos) +- [mongodb-client-encryption](https://github.com/mongodb/libmongocrypt#readme) + +Some of these packages include native C++ extensions, consult the [trouble shooting guide here](https://github.com/mongodb/node-mongodb-native/blob/4.1/docs/native-extensions.md) if you run into issues. + +## Quick Start + +This guide will show you how to set up a simple application using Node.js and MongoDB. Its scope is only how to set up the driver and perform the simple CRUD operations. For more in-depth coverage, see the [official documentation](https://docs.mongodb.com/drivers/node/). + +### Create the `package.json` file + +First, create a directory where your application will live. + +```bash +mkdir myProject +cd myProject +``` + +Enter the following command and answer the questions to create the initial structure for your new project: + +```bash +npm init -y +``` + +Next, install the driver as a dependency. + +```bash +npm install mongodb +``` + +### Start a MongoDB Server + +For complete MongoDB installation instructions, see [the manual](https://docs.mongodb.org/manual/installation/). + +1. Download the right MongoDB version from [MongoDB](https://www.mongodb.org/downloads) +2. Create a database directory (in this case under **/data**). +3. Install and start a `mongod` process. + +```bash +mongod --dbpath=/data +``` + +You should see the **mongod** process start up and print some status information. + +### Connect to MongoDB + +Create a new **app.js** file and add the following code to try out some basic CRUD +operations using the MongoDB driver. + +Add code to connect to the server and the database **myProject**: + +> **NOTE:** All the examples below use async/await syntax. +> +> However, all async API calls support an optional callback as the final argument, +> if a callback is provided a Promise will not be returned. + +```js +const { MongoClient } = require('mongodb'); +// or as an es module: +// import { MongoClient } from 'mongodb' + +// Connection URL +const url = 'mongodb://localhost:27017'; +const client = new MongoClient(url); + +// Database Name +const dbName = 'myProject'; + +async function main() { + // Use connect method to connect to the server + await client.connect(); + console.log('Connected successfully to server'); + const db = client.db(dbName); + const collection = db.collection('documents'); + + // the following code examples can be pasted here... + + return 'done.'; +} + +main() + .then(console.log) + .catch(console.error) + .finally(() => client.close()); +``` + +Run your app from the command line with: + +```bash +node app.js +``` + +The application should print **Connected successfully to server** to the console. + +### Insert a Document + +Add to **app.js** the following function which uses the **insertMany** +method to add three documents to the **documents** collection. + +```js +const insertResult = await collection.insertMany([{ a: 1 }, { a: 2 }, { a: 3 }]); +console.log('Inserted documents =>', insertResult); +``` + +The **insertMany** command returns an object with information about the insert operations. + +### Find All Documents + +Add a query that returns all the documents. + +```js +const findResult = await collection.find({}).toArray(); +console.log('Found documents =>', findResult); +``` + +This query returns all the documents in the **documents** collection. +If you add this below the insertMany example you'll see the document's you've inserted. + +### Find Documents with a Query Filter + +Add a query filter to find only documents which meet the query criteria. + +```js +const filteredDocs = await collection.find({ a: 3 }).toArray(); +console.log('Found documents filtered by { a: 3 } =>', filteredDocs); +``` + +Only the documents which match `'a' : 3` should be returned. + +### Update a document + +The following operation updates a document in the **documents** collection. + +```js +const updateResult = await collection.updateOne({ a: 3 }, { $set: { b: 1 } }); +console.log('Updated documents =>', updateResult); +``` + +The method updates the first document where the field **a** is equal to **3** by adding a new field **b** to the document set to **1**. `updateResult` contains information about whether there was a matching document to update or not. + +### Remove a document + +Remove the document where the field **a** is equal to **3**. + +```js +const deleteResult = await collection.deleteMany({ a: 3 }); +console.log('Deleted documents =>', deleteResult); +``` + +### Index a Collection + +[Indexes](https://docs.mongodb.org/manual/indexes/) can improve your application's +performance. The following function creates an index on the **a** field in the +**documents** collection. + +```js +const indexName = await collection.createIndex({ a: 1 }); +console.log('index name =', indexName); +``` + +For more detailed information, see the [indexing strategies page](https://docs.mongodb.com/manual/applications/indexes/). + +## Error Handling + +If you need to filter certain errors from our driver we have a helpful tree of errors described in [docs/errors.md](https://github.com/mongodb/node-mongodb-native/blob/4.1/docs/errors.md). + +It is our recommendation to use `instanceof` checks on errors and to avoid relying on parsing `error.message` and `error.name` strings in your code. +We guarantee `instanceof` checks will pass according to semver guidelines, but errors may be sub-classed or their messages may change at any time, even patch releases, as we see fit to increase the helpfulness of the errors. + +Any new errors we add to the driver will directly extend an existing error class and no existing error will be moved to a different parent class outside of a major release. +This means `instanceof` will always be able to accurately capture the errors that our driver throws (or returns in a callback). + +```typescript +const client = new MongoClient(url); +await client.connect(); +const collection = client.db().collection('collection'); + +try { + await collection.insertOne({ _id: 1 }); + await collection.insertOne({ _id: 1 }); // duplicate key error +} catch (error) { + if (error instanceof MongoServerError) { + console.log(`Error worth logging: ${error}`); // special case for some reason + } + throw error; // still want to crash +} +``` + +## Next Steps + +- [MongoDB Documentation](https://docs.mongodb.com/manual/) +- [MongoDB Node Driver Documentation](https://docs.mongodb.com/drivers/node/) +- [Read about Schemas](https://docs.mongodb.com/manual/core/data-modeling-introduction/) +- [Star us on GitHub](https://github.com/mongodb/node-mongodb-native) + +## License + +[Apache 2.0](LICENSE.md) + +© 2009-2012 Christian Amor Kvalheim +© 2012-present MongoDB [Contributors](https://github.com/mongodb/node-mongodb-native/blob/4.1/CONTRIBUTORS.md) diff --git a/node_modules/mongodb/etc/prepare.js b/node_modules/mongodb/etc/prepare.js new file mode 100644 index 0000000..2039d0b --- /dev/null +++ b/node_modules/mongodb/etc/prepare.js @@ -0,0 +1,12 @@ +#! /usr/bin/env node +var cp = require('child_process');

If your app uses only one database, you should use `mongoose.connect`. If you need to create additional connections, use `mongoose.createConnection`. + +Both `connect` and `createConnection` take a `mongodb://` URI, or the parameters `host, database, port, options`. + +```js +await mongoose.connect('mongodb://localhost/my_database'); +``` + +Once connected, the `open` event is fired on the `Connection` instance. If you're using `mongoose.connect`, the `Connection` is `mongoose.connection`. Otherwise, `mongoose.createConnection` return value is a `Connection`. + +**Note:** _If the local connection fails then try using 127.0.0.1 instead of localhost. Sometimes issues may arise when the local hostname has been changed._ + +**Important!** Mongoose buffers all the commands until it's connected to the database. This means that you don't have to wait until it connects to MongoDB in order to define models, run queries, etc. + +### Defining a Model + +Models are defined through the `Schema` interface. + +```js +const Schema = mongoose.Schema; +const ObjectId = Schema.ObjectId; + +const BlogPost = new Schema({ + author: ObjectId, + title: String, + body: String, +  date: Date +}); +``` + +Aside from defining the structure of your documents and the types of data you're storing, a Schema handles the definition of: + +* [Validators](http://mongoosejs.com/docs/validation.html) (async and sync) +* [Defaults](http://mongoosejs.com/docs/api.html#schematype_SchemaType-default) +* [Getters](http://mongoosejs.com/docs/api.html#schematype_SchemaType-get) +* [Setters](http://mongoosejs.com/docs/api.html#schematype_SchemaType-set) +* [Indexes](http://mongoosejs.com/docs/guide.html#indexes) +* [Middleware](http://mongoosejs.com/docs/middleware.html) +* [Methods](http://mongoosejs.com/docs/guide.html#methods) definition +* [Statics](http://mongoosejs.com/docs/guide.html#statics) definition +* [Plugins](http://mongoosejs.com/docs/plugins.html) +* [pseudo-JOINs](http://mongoosejs.com/docs/populate.html) + +The following example shows some of these features: + +```js +const Comment = new Schema({ + name: { type: String, default: 'hahaha' }, + age: { type: Number, min: 18, index: true }, + bio: { type: String, match: /[a-z]/ }, + date: { type: Date, default: Date.now }, + buff: Buffer +}); + +// a setter +Comment.path('name').set(function (v) { + return capitalize(v); +}); + +// middleware +Comment.pre('save', function (next) { + notify(this.get('email')); + next(); +}); +``` + +Take a look at the example in [`examples/schema/schema.js`](https://github.com/Automattic/mongoose/blob/master/examples/schema/schema.js) for an end-to-end example of a typical setup. + +### Accessing a Model + +Once we define a model through `mongoose.model('ModelName', mySchema)`, we can access it through the same function + +```js +const MyModel = mongoose.model('ModelName'); +``` + +Or just do it all at once + +```js +const MyModel = mongoose.model('ModelName', mySchema); +``` + +The first argument is the _singular_ name of the collection your model is for. **Mongoose automatically looks for the _plural_ version of your model name.** For example, if you use + +```js +const MyModel = mongoose.model('Ticket', mySchema); +``` + +Then Mongoose will create the model for your __tickets__ collection, not your __ticket__ collection. + +Once we have our model, we can then instantiate it, and save it: + +```js +const instance = new MyModel(); +instance.my.key = 'hello'; +instance.save(function (err) { + // +}); +``` + +Or we can find documents from the same collection + +```js +MyModel.find({}, function (err, docs) { + // docs.forEach +}); +``` + +You can also `findOne`, `findById`, `update`, etc. + +```js +const instance = await MyModel.findOne({ ... }); +console.log(instance.my.key); // 'hello' +``` + +For more details check out [the docs](http://mongoosejs.com/docs/queries.html). + +**Important!** If you opened a separate connection using `mongoose.createConnection()` but attempt to access the model through `mongoose.model('ModelName')` it will not work as expected since it is not hooked up to an active db connection. In this case access your model through the connection you created: + +```js +const conn = mongoose.createConnection('your connection string'); +const MyModel = conn.model('ModelName', schema); +const m = new MyModel; +m.save(); // works +``` + +vs + +```js +const conn = mongoose.createConnection('your connection string'); +const MyModel = mongoose.model('ModelName', schema); +const m = new MyModel; +m.save(); // does not work b/c the default connection object was never connected +``` + +### Embedded Documents + +In the first example snippet, we defined a key in the Schema that looks like: + +``` +comments: [Comment] +``` + +Where `Comment` is a `Schema` we created. This means that creating embedded documents is as simple as: + +```js +// retrieve my model +const BlogPost = mongoose.model('BlogPost'); + +// create a blog post +const post = new BlogPost(); + +// create a comment +post.comments.push({ title: 'My comment' }); + +post.save(function (err) { + if (!err) console.log('Success!'); +}); +``` + +The same goes for removing them: + +```js +BlogPost.findById(myId, function (err, post) { + if (!err) { + post.comments[0].remove(); + post.save(function (err) { + // do something + }); + } +}); +``` + +Embedded documents enjoy all the same features as your models. Defaults, validators, middleware. Whenever an error occurs, it's bubbled to the `save()` error callback, so error handling is a snap! + + +### Middleware + +See the [docs](http://mongoosejs.com/docs/middleware.html) page. + +#### Intercepting and mutating method arguments + +You can intercept method arguments via middleware. + +For example, this would allow you to broadcast changes about your Documents every time someone `set`s a path in your Document to a new value: + +```js +schema.pre('set', function (next, path, val, typel) { + // `this` is the current Document + this.emit('set', path, val); + + // Pass control to the next pre + next(); +}); +``` + +Moreover, you can mutate the incoming `method` arguments so that subsequent middleware see different values for those arguments. To do so, just pass the new values to `next`: + +```js +.pre(method, function firstPre (next, methodArg1, methodArg2) { + // Mutate methodArg1 + next("altered-" + methodArg1.toString(), methodArg2); +}); + +// pre declaration is chainable +.pre(method, function secondPre (next, methodArg1, methodArg2) { + console.log(methodArg1); + // => 'altered-originalValOfMethodArg1' + + console.log(methodArg2); + // => 'originalValOfMethodArg2' + + // Passing no arguments to `next` automatically passes along the current argument values + // i.e., the following `next()` is equivalent to `next(methodArg1, methodArg2)` + // and also equivalent to, with the example method arg + // values, `next('altered-originalValOfMethodArg1', 'originalValOfMethodArg2')` + next(); +}); +``` + +#### Schema gotcha + +`type`, when used in a schema has special meaning within Mongoose. If your schema requires using `type` as a nested property you must use object notation: + +```js +new Schema({ + broken: { type: Boolean }, + asset: { + name: String, + type: String // uh oh, it broke. asset will be interpreted as String + } +}); + +new Schema({ + works: { type: Boolean }, + asset: { + name: String, + type: { type: String } // works. asset is an object with a type property + } +}); +``` + +### Driver Access + +Mongoose is built on top of the [official MongoDB Node.js driver](https://github.com/mongodb/node-mongodb-native). Each mongoose model keeps a reference to a [native MongoDB driver collection](http://mongodb.github.io/node-mongodb-native/2.1/api/Collection.html). The collection object can be accessed using `YourModel.collection`. However, using the collection object directly bypasses all mongoose features, including hooks, validation, etc. The one +notable exception that `YourModel.collection` still buffers +commands. As such, `YourModel.collection.find()` will **not** +return a cursor. + +## API Docs + +Find the API docs [here](http://mongoosejs.com/docs/api.html), generated using [dox](https://github.com/tj/dox)

Keep in mind that, as of MongoDB 3.4, MongoDB only allows one operation per socket at a time, so you may want to increase this if you find you have a few slow queries that are blocking faster queries from proceeding. See [Slow Trains in MongoDB and Node.js](http://thecodebarbarian.com/slow-trains-in-mongodb-and-nodejs). + * @param {Number} [options.serverSelectionTimeoutMS] If `useUnifiedTopology = true`, the MongoDB driver will try to find a server to send any given operation to, and keep retrying for `serverSelectionTimeoutMS` milliseconds before erroring out. If not set, the MongoDB driver defaults to using `30000` (30 seconds). + * @param {Number} [options.heartbeatFrequencyMS] If `useUnifiedTopology = true`, the MongoDB driver sends a heartbeat every `heartbeatFrequencyMS` to check on the status of the connection. A heartbeat is subject to `serverSelectionTimeoutMS`, so the MongoDB driver will retry failed heartbeats for up to 30 seconds by default. Mongoose only emits a `'disconnected'` event after a heartbeat has failed, so you may want to decrease this setting to reduce the time between when your server goes down and when Mongoose emits `'disconnected'`. We recommend you do **not** set this setting below 1000, too many heartbeats can lead to performance degradation. + * @param {Boolean} [options.autoIndex=true] Mongoose-specific option. Set to false to disable automatic index creation for all models associated with this connection. + * @param {Number} [options.reconnectTries=30] If you're connected to a single server or mongos proxy (as opposed to a replica set), the MongoDB driver will try to reconnect every `reconnectInterval` milliseconds for `reconnectTries` times, and give up afterward. When the driver gives up, the mongoose connection emits a `reconnectFailed` event. This option does nothing for replica set connections. + * @param {Number} [options.reconnectInterval=1000] See `reconnectTries` option above. + * @param {Class} [options.promiseLibrary] Sets the [underlying driver's promise library](http://mongodb.github.io/node-mongodb-native/3.1/api/MongoClient.html). + * @param {Number} [options.connectTimeoutMS=30000] How long the MongoDB driver will wait before killing a socket due to inactivity _during initial connection_. Defaults to 30000. This option is passed transparently to [Node.js' `socket#setTimeout()` function](https://nodejs.org/api/net.html#net_socket_settimeout_timeout_callback). + * @param {Number} [options.socketTimeoutMS=30000] How long the MongoDB driver will wait before killing a socket due to inactivity _after initial connection_. A socket may be inactive because of either no activity or a long-running operation. This is set to `30000` by default, you should set this to 2-3x your longest running operation if you expect some of your database operations to run longer than 20 seconds. This option is passed to [Node.js `socket#setTimeout()` function](https://nodejs.org/api/net.html#net_socket_settimeout_timeout_callback) after the MongoDB driver successfully completes. + * @param {Number} [options.family=0] Passed transparently to [Node.js' `dns.lookup()`](https://nodejs.org/api/dns.html#dns_dns_lookup_hostname_options_callback) function.

Note that setting nested arrays of arrays can get unweildy quickly. Check out the [tests](https://github.com/aheckmann/mpath/blob/master/test/index.js) for more extreme examples. + +#####Maps + +`mpath.set` also accepts an optional `map` argument which receives each individual value being set.

For example, a `distinct` query does not support specifying options like `hint` or field selection. In this case an error will be thrown so you can catch these mistakes in development. + +## Debug support + +Debug mode is provided through the use of the [debug](https://github.com/visionmedia/debug) module. To enable: + + DEBUG=mquery node yourprogram.js + +Read the debug module documentation for more details. + +## General compatibility + +#### ObjectIds + +`mquery` clones query arguments before passing them to a `collection` method for execution. +This prevents accidental side-affects to the objects you pass. +To clone `ObjectIds` we need to make some assumptions. + +First, to check if an object is an `ObjectId`, we check its constructors name. If it matches either +`ObjectId` or `ObjectID` we clone it. + +To clone `ObjectIds`, we call its optional `clone` method. If a `clone` method does not exist, we fall +back to calling `new obj.constructor(obj.id)`. We assume, for compatibility with the +Node.js driver, that the `ObjectId` instance has a public `id` property and that +when creating an `ObjectId` instance we can pass that `id` as an argument. + +#### Read Preferences + +`mquery` supports specifying [Read Preferences]() to control from which MongoDB node your query will read. +The Read Preferences spec also support specifying tags. To pass tags, some +drivers (Node.js driver) require passing a special constructor that handles both the read preference and its tags. +If you need to specify tags, pass an instance of your drivers ReadPreference constructor or roll your own. `mquery` will store whatever you provide and pass later to your collection during execution. + +## Future goals + + - mongo shell compatibility + - browser compatibility + +## Installation + + $ npm install mquery + +## License + +[MIT](https://github.com/aheckmann/mquery/blob/master/LICENSE) + diff --git a/node_modules/mquery/SECURITY.md b/node_modules/mquery/SECURITY.md new file mode 100644 index 0000000..41b89d8 --- /dev/null +++ b/node_modules/mquery/SECURITY.md @@ -0,0 +1 @@ +Please follow the instructions on [Tidelift's security page](https://tidelift.com/docs/security) to report a security issue. diff --git a/node_modules/mquery/lib/collection/collection.js b/node_modules/mquery/lib/collection/collection.js new file mode 100644 index 0000000..28b6982 --- /dev/null +++ b/node_modules/mquery/lib/collection/collection.js @@ -0,0 +1,47 @@ +'use strict'; + +/** + * methods a collection must implement + */ + +const methods = [ + 'find', + 'findOne', + 'update', + 'updateMany', + 'updateOne', + 'replaceOne', + 'remove', + 'count', + 'distinct', + 'findOneAndDelete', + 'findOneAndUpdate', + 'aggregate', + 'findCursor', + 'deleteOne', + 'deleteMany' +]; + +/** + * Collection base class from which implementations inherit + */ + +function Collection() {} + +for (let i = 0, len = methods.length; i < len; ++i) { + const method = methods[i]; + Collection.prototype[method] = notImplemented(method); +} + +module.exports = exports = Collection; +Collection.methods = methods; + +/** + * creates a function which throws an implementation error + */ + +function notImplemented(method) { + return function() { + throw new Error('collection.' + method + ' not implemented'); + }; +} diff --git a/node_modules/mquery/lib/collection/index.js b/node_modules/mquery/lib/collection/index.js new file mode 100644 index 0000000..4faa032 --- /dev/null +++ b/node_modules/mquery/lib/collection/index.js @@ -0,0 +1,13 @@ +'use strict'; + +const env = require('../env'); + +if ('unknown' == env.type) { + throw new Error('Unknown environment'); +} + +module.exports = + env.isNode ?

You also _should_ install +the [`supports-color`](https://npmjs.org/supports-color) module alongside debug, +otherwise debug will only use a small handful of basic colors. + + + +#### Web Browser + +Colors are also enabled on "Web Inspectors" that understand the `%c` formatting +option. These are WebKit web inspectors, Firefox ([since version +31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/)) +and the Firebug plugin for Firefox (any version). + + + + +## Millisecond diff + +When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls. + + + +When stdout is not a TTY, `Date#toISOString()` is used, making it more useful for logging the debug information as shown below: + + + + +## Conventions + +If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser". If you append a "*" to the end of your name, it will always be enabled regardless of the setting of the DEBUG environment variable. You can then use it for normal output as well as debug output. + +## Wildcards + +The `*` character may be used as a wildcard. Suppose for example your library has +debuggers named "connect:bodyParser", "connect:compress", "connect:session", +instead of listing all three with +`DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do +`DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`. + +You can also exclude specific debuggers by prefixing them with a "-" character. +For example, `DEBUG=*,-connect:*` would include all debuggers except those +starting with "connect:". + +## Environment Variables + +When running through Node.js, you can set a few environment variables that will +change the behavior of the debug logging: + +| Name | Purpose | +|-----------|-------------------------------------------------| +| `DEBUG` | Enables/disables specific debugging namespaces. | +| `DEBUG_HIDE_DATE` | Hide date from debug output (non-TTY). | +| `DEBUG_COLORS`| Whether or not to use colors in the debug output. | +| `DEBUG_DEPTH` | Object inspection depth. | +| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. | + + +__Note:__ The environment variables beginning with `DEBUG_` end up being +converted into an Options object that gets used with `%o`/`%O` formatters. +See the Node.js documentation for +[`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options) +for the complete list. + +## Formatters + +Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting. +Below are the officially supported formatters: + +| Formatter | Representation | +|-----------|----------------| +| `%O` | Pretty-print an Object on multiple lines. | +| `%o` | Pretty-print an Object all on a single line. | +| `%s` | String. | +| `%d` | Number (both integer and float). | +| `%j` | JSON. Replaced with the string '[Circular]' if the argument contains circular references. | +| `%%` | Single percent sign ('%'). This does not consume an argument. | + + +### Custom formatters + +You can add custom formatters by extending the `debug.formatters` object. +For example, if you wanted to add support for rendering a Buffer as hex with +`%h`, you could do something like: + +```js +const createDebug = require('debug') +createDebug.formatters.h = (v) => { + return v.toString('hex') +} + +// …elsewhere +const debug = createDebug('foo') +debug('this is hex: %h', new Buffer('hello world')) +// foo this is hex: 68656c6c6f20776f726c6421 +0ms +``` + + +## Browser Support + +You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify), +or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest), +if you don't want to build it yourself. + +Debug's enable state is currently persisted by `localStorage`. +Consider the situation shown below where you have `worker:a` and `worker:b`, +and wish to debug both. You can enable this using `localStorage.debug`: + +```js +localStorage.debug = 'worker:*' +``` + +And then refresh the page. + +```js +a = debug('worker:a'); +b = debug('worker:b'); + +setInterval(function(){ + a('doing some work'); +}, 1000); + +setInterval(function(){ + b('doing some work'); +}, 1200); +``` + + +## Output streams + + By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method: + +Example [_stdout.js_](./examples/node/stdout.js): + +```js +var debug = require('debug'); +var error = debug('app:error'); + +// by default stderr is used +error('goes to stderr!'); + +var log = debug('app:log'); +// set this namespace to log via console.log +log.log = console.log.bind(console); // don't forget to bind to console! +log('goes to stdout'); +error('still goes to stderr!'); + +// set all output to go via console.info +// overrides all per-namespace log settings +debug.log = console.info.bind(console); +error('now goes to stdout via console.info'); +log('still goes to stdout, but via console.info now'); +``` + +## Extend +You can simply extend debugger +```js +const log = require('debug')('auth'); + +//creates new debug instance with extended namespace +const logSign = log.extend('sign'); +const logLogin = log.extend('login'); + +log('hello'); // auth hello +logSign('hello'); //auth:sign hello +logLogin('hello'); //auth:login hello +``` + +## Set dynamically + +You can also enable debug dynamically by calling the `enable()` method : + +```js +let debug = require('debug'); + +console.log(1, debug.enabled('test')); + +debug.enable('test'); +console.log(2, debug.enabled('test')); + +debug.disable(); +console.log(3, debug.enabled('test')); + +``` + +print : +``` +1 false +2 true +3 false +``` + +Usage : +`enable(namespaces)` +`namespaces` can include modes separated by a colon and wildcards. + +Note that calling `enable()` completely overrides previously set DEBUG variable : + +``` +$ DEBUG=foo node -e 'var dbg = require("debug"); dbg.enable("bar"); console.log(dbg.enabled("foo"))' +=> false +``` + +`disable()` + +Will disable all namespaces. The functions returns the namespaces currently +enabled (and skipped). This can be useful if you want to disable debugging +temporarily without knowing what was enabled to begin with. + +For example: + +```js +let debug = require('debug'); +debug.enable('foo:*,-foo:bar'); +let namespaces = debug.disable(); +debug.enable(namespaces); +``` + +Note: There is no guarantee that the string will be identical to the initial +enable string, but semantically they will be identical. + +## Checking whether a debug target is enabled + +After you've created a debug instance, you can determine whether or not it is +enabled by checking the `enabled` property: + +```javascript +const debug = require('debug')('http'); + +if (debug.enabled) { + // do stuff... +} +``` + +You can also manually toggle this property to force the debug instance to be +enabled or disabled. + + +## Authors + + - TJ Holowaychuk + - Nathan Rajlich + - Andrew Rhyne + +## Backers + +Support us with a monthly donation and help us continue our activities.

Always be careful with this option. + +```javascript +var protoObject = qs.parse('a[hasOwnProperty]=b', { allowPrototypes: true }); +assert.deepEqual(protoObject, { a: { hasOwnProperty: 'b' } }); +``` + +URI encoded strings work too: + +```javascript +assert.deepEqual(qs.parse('a%5Bb%5D=c'), { + a: { b: 'c' } +}); +``` + +You can also nest your objects, like `'foo[bar][baz]=foobarbaz'`: + +```javascript +assert.deepEqual(qs.parse('foo[bar][baz]=foobarbaz'), { + foo: { + bar: { + baz: 'foobarbaz' + } + } +}); +``` + +By default, when nesting objects **qs** will only parse up to 5 children deep. This means if you attempt to parse a string like +`'a[b][c][d][e][f][g][h][i]=j'` your resulting object will be: + +```javascript +var expected = { + a: { + b: { + c: { + d: { + e: { + f: { + '[g][h][i]': 'j' + } + } + } + } + } + } +}; +var string = 'a[b][c][d][e][f][g][h][i]=j'; +assert.deepEqual(qs.parse(string), expected); +``` + +This depth can be overridden by passing a `depth` option to `qs.parse(string, [options])`: + +```javascript +var deep = qs.parse('a[b][c][d][e][f][g][h][i]=j', { depth: 1 }); +assert.deepEqual(deep, { a: { b: { '[c][d][e][f][g][h][i]': 'j' } } }); +``` + +The depth limit helps mitigate abuse when **qs** is used to parse user input, and it is recommended to keep it a reasonably small number. + +For similar reasons, by default **qs** will only parse up to 1000 parameters. This can be overridden by passing a `parameterLimit` option: + +```javascript +var limited = qs.parse('a=b&c=d', { parameterLimit: 1 }); +assert.deepEqual(limited, { a: 'b' }); +``` + +To bypass the leading question mark, use `ignoreQueryPrefix`: + +```javascript +var prefixed = qs.parse('?a=b&c=d', { ignoreQueryPrefix: true }); +assert.deepEqual(prefixed, { a: 'b', c: 'd' }); +``` + +An optional delimiter can also be passed: + +```javascript +var delimited = qs.parse('a=b;c=d', { delimiter: ';' }); +assert.deepEqual(delimited, { a: 'b', c: 'd' }); +``` + +Delimiters can be a regular expression too: + +```javascript +var regexed = qs.parse('a=b;c=d,e=f', { delimiter: /[;,]/ }); +assert.deepEqual(regexed, { a: 'b', c: 'd', e: 'f' }); +``` + +Option `allowDots` can be used to enable dot notation: + +```javascript +var withDots = qs.parse('a.b=c', { allowDots: true }); +assert.deepEqual(withDots, { a: { b: 'c' } }); +``` + +If you have to deal with legacy browsers or services, there's +also support for decoding percent-encoded octets as iso-8859-1: + +```javascript +var oldCharset = qs.parse('a=%A7', { charset: 'iso-8859-1' }); +assert.deepEqual(oldCharset, { a: '§' }); +``` + +Some services add an initial `utf8=✓` value to forms so that old +Internet Explorer versions are more likely to submit the form as +utf-8. Additionally, the server can check the value against wrong +encodings of the checkmark character and detect that a query string +or `application/x-www-form-urlencoded` body was *not* sent as +utf-8, eg. if the form had an `accept-charset` parameter or the +containing page had a different character set. + +**qs** supports this mechanism via the `charsetSentinel` option. +If specified, the `utf8` parameter will be omitted from the +returned object. It will be used to switch to `iso-8859-1`/`utf-8` +mode depending on how the checkmark is encoded. + +**Important**: When you specify both the `charset` option and the +`charsetSentinel` option, the `charset` will be overridden when +the request contains a `utf8` parameter from which the actual +charset can be deduced. In that sense the `charset` will behave +as the default charset rather than the authoritative charset. + +```javascript +var detectedAsUtf8 = qs.parse('utf8=%E2%9C%93&a=%C3%B8', { + charset: 'iso-8859-1', + charsetSentinel: true +}); +assert.deepEqual(detectedAsUtf8, { a: 'ø' }); + +// Browsers encode the checkmark as ✓ when submitting as iso-8859-1: +var detectedAsIso8859_1 = qs.parse('utf8=%26%2310003%3B&a=%F8', { + charset: 'utf-8', + charsetSentinel: true +}); +assert.deepEqual(detectedAsIso8859_1, { a: 'ø' }); +``` + +If you want to decode the `&#...;` syntax to the actual character, +you can specify the `interpretNumericEntities` option as well: + +```javascript +var detectedAsIso8859_1 = qs.parse('a=%26%239786%3B', { + charset: 'iso-8859-1', + interpretNumericEntities: true +}); +assert.deepEqual(detectedAsIso8859_1, { a: '☺' }); +``` + +It also works when the charset has been detected in `charsetSentinel` +mode. + +### Parsing Arrays + +**qs** can also parse arrays using a similar `[]` notation: + +```javascript +var withArray = qs.parse('a[]=b&a[]=c'); +assert.deepEqual(withArray, { a: ['b', 'c'] }); +``` + +You may specify an index as well: + +```javascript +var withIndexes = qs.parse('a[1]=c&a[0]=b'); +assert.deepEqual(withIndexes, { a: ['b', 'c'] }); +``` + +Note that the only difference between an index in an array and a key in an object is that the value between the brackets must be a number +to create an array. When creating arrays with specific indices, **qs** will compact a sparse array to only the existing values preserving +their order: + +```javascript +var noSparse = qs.parse('a[1]=b&a[15]=c'); +assert.deepEqual(noSparse, { a: ['b', 'c'] }); +``` + +Note that an empty string is also a value, and will be preserved: + +```javascript +var withEmptyString = qs.parse('a[]=&a[]=b'); +assert.deepEqual(withEmptyString, { a: ['', 'b'] }); + +var withIndexedEmptyString = qs.parse('a[0]=b&a[1]=&a[2]=c'); +assert.deepEqual(withIndexedEmptyString, { a: ['b', '', 'c'] }); +``` + +**qs** will also limit specifying indices in an array to a maximum index of `20`. Any array members with an index of greater than `20` will +instead be converted to an object with the index as the key. This is needed to handle cases when someone sent, for example, `a[999999999]` and it will take significant time to iterate over this huge array. + +```javascript +var withMaxIndex = qs.parse('a[100]=b'); +assert.deepEqual(withMaxIndex, { a: { '100': 'b' } }); +``` + +This limit can be overridden by passing an `arrayLimit` option: + +```javascript +var withArrayLimit = qs.parse('a[1]=b', { arrayLimit: 0 }); +assert.deepEqual(withArrayLimit, { a: { '1': 'b' } }); +``` + +To disable array parsing entirely, set `parseArrays` to `false`. + +```javascript +var noParsingArrays = qs.parse('a[]=b', { parseArrays: false }); +assert.deepEqual(noParsingArrays, { a: { '0': 'b' } }); +``` + +If you mix notations, **qs** will merge the two items into an object: + +```javascript +var mixedNotation = qs.parse('a[0]=b&a[b]=c'); +assert.deepEqual(mixedNotation, { a: { '0': 'b', b: 'c' } }); +``` + +You can also create arrays of objects: + +```javascript +var arraysOfObjects = qs.parse('a[][b]=c'); +assert.deepEqual(arraysOfObjects, { a: [{ b: 'c' }] }); +``` + +Some people use comma to join array, **qs** can parse it: +```javascript +var arraysOfObjects = qs.parse('a=b,c', { comma: true }) +assert.deepEqual(arraysOfObjects, { a: ['b', 'c'] }) +``` +(_this cannot convert nested objects, such as `a={b:1},{c:d}`_) + +### Stringifying + +[](#preventEval) +```javascript +qs.stringify(object, [options]); +``` + +When stringifying, **qs** by default URI encodes output. Objects are stringified as you would expect: + +```javascript +assert.equal(qs.stringify({ a: 'b' }), 'a=b'); +assert.equal(qs.stringify({ a: { b: 'c' } }), 'a%5Bb%5D=c'); +``` + +This encoding can be disabled by setting the `encode` option to `false`: + +```javascript +var unencoded = qs.stringify({ a: { b: 'c' } }, { encode: false }); +assert.equal(unencoded, 'a[b]=c'); +``` + +Encoding can be disabled for keys by setting the `encodeValuesOnly` option to `true`: +```javascript +var encodedValues = qs.stringify( + { a: 'b', c: ['d', 'e=f'], f: [['g'], ['h']] }, + { encodeValuesOnly: true } +); +assert.equal(encodedValues,'a=b&c[0]=d&c[1]=e%3Df&f[0][0]=g&f[1][0]=h'); +``` + +This encoding can also be replaced by a custom encoding method set as `encoder` option: + +```javascript +var encoded = qs.stringify({ a: { b: 'c' } }, { encoder: function (str) { + // Passed in values `a`, `b`, `c` + return // Return encoded string +}}) +``` + +_(Note: the `encoder` option does not apply if `encode` is `false`)_ + +Analogue to the `encoder` there is a `decoder` option for `parse` to override decoding of properties and values: + +```javascript +var decoded = qs.parse('x=z', { decoder: function (str) { + // Passed in values `x`, `z` + return // Return decoded string +}}) +``` + +Examples beyond this point will be shown as though the output is not URI encoded for clarity. Please note that the return values in these cases *will* be URI encoded during real usage. + +When arrays are stringified, by default they are given explicit indices: + +```javascript +qs.stringify({ a: ['b', 'c', 'd'] }); +// 'a[0]=b&a[1]=c&a[2]=d' +``` + +You may override this by setting the `indices` option to `false`: + +```javascript +qs.stringify({ a: ['b', 'c', 'd'] }, { indices: false }); +// 'a=b&a=c&a=d' +``` + +You may use the `arrayFormat` option to specify the format of the output array: + +```javascript +qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'indices' }) +// 'a[0]=b&a[1]=c' +qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'brackets' }) +// 'a[]=b&a[]=c' +qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'repeat' }) +// 'a=b&a=c' +qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'comma' }) +// 'a=b,c' +``` + +When objects are stringified, by default they use bracket notation: + +```javascript +qs.stringify({ a: { b: { c: 'd', e: 'f' } } }); +// 'a[b][c]=d&a[b][e]=f' +``` + +You may override this to use dot notation by setting the `allowDots` option to `true`: + +```javascript +qs.stringify({ a: { b: { c: 'd', e: 'f' } } }, { allowDots: true }); +// 'a.b.c=d&a.b.e=f' +``` + +Empty strings and null values will omit the value, but the equals sign (=) remains in place: + +```javascript +assert.equal(qs.stringify({ a: '' }), 'a='); +``` + +Key with no values (such as an empty object or array) will return nothing: + +```javascript +assert.equal(qs.stringify({ a: [] }), ''); +assert.equal(qs.stringify({ a: {} }), ''); +assert.equal(qs.stringify({ a: [{}] }), ''); +assert.equal(qs.stringify({ a: { b: []} }), ''); +assert.equal(qs.stringify({ a: { b: {}} }), ''); +``` + +Properties that are set to `undefined` will be omitted entirely: + +```javascript +assert.equal(qs.stringify({ a: null, b: undefined }), 'a='); +``` + +The query string may optionally be prepended with a question mark: + +```javascript +assert.equal(qs.stringify({ a: 'b', c: 'd' }, { addQueryPrefix: true }), '?a=b&c=d'); +``` + +The delimiter may be overridden with stringify as well: + +```javascript +assert.equal(qs.stringify({ a: 'b', c: 'd' }, { delimiter: ';' }), 'a=b;c=d'); +``` + +If you only want to override the serialization of `Date` objects, you can provide a `serializeDate` option: + +```javascript +var date = new Date(7); +assert.equal(qs.stringify({ a: date }), 'a=1970-01-01T00:00:00.007Z'.replace(/:/g, '%3A')); +assert.equal( + qs.stringify({ a: date }, { serializeDate: function (d) { return d.getTime(); } }), + 'a=7' +); +``` + +You may use the `sort` option to affect the order of parameter keys: + +```javascript +function alphabeticalSort(a, b) { + return a.localeCompare(b); +} +assert.equal(qs.stringify({ a: 'c', z: 'y', b : 'f' }, { sort: alphabeticalSort }), 'a=c&b=f&z=y'); +``` + +Finally, you can use the `filter` option to restrict which keys will be included in the stringified output. +If you pass a function, it will be called for each key to obtain the replacement value. Otherwise, if you +pass an array, it will be used to select properties and array indices for stringification: + +```javascript +function filterFunc(prefix, value) { + if (prefix == 'b') { + // Return an `undefined` value to omit a property. + return; + } + if (prefix == 'e[f]') { + return value.getTime(); + } + if (prefix == 'e[g][0]') { + return value * 2; + } + return value; +} +qs.stringify({ a: 'b', c: 'd', e: { f: new Date(123), g: [2] } }, { filter: filterFunc }); +// 'a=b&c=d&e[f]=123&e[g][0]=4' +qs.stringify({ a: 'b', c: 'd', e: 'f' }, { filter: ['a', 'e'] }); +// 'a=b&e=f' +qs.stringify({ a: ['b', 'c', 'd'], e: 'f' }, { filter: ['a', 0, 2] }); +// 'a[0]=b&a[2]=d' +``` + +### Handling of `null` values + +By default, `null` values are treated like empty strings: + +```javascript +var withNull = qs.stringify({ a: null, b: '' }); +assert.equal(withNull, 'a=&b='); +``` + +Parsing does not distinguish between parameters with and without equal signs. Both are converted to empty strings. + +```javascript +var equalsInsensitive = qs.parse('a&b='); +assert.deepEqual(equalsInsensitive, { a: '', b: '' }); +``` + +To distinguish between `null` values and empty strings use the `strictNullHandling` flag. In the result string the `null` +values have no `=` sign: + +```javascript +var strictNull = qs.stringify({ a: null, b: '' }, { strictNullHandling: true }); +assert.equal(strictNull, 'a&b='); +``` + +To parse values without `=` back to `null` use the `strictNullHandling` flag: + +```javascript +var parsedStrictNull = qs.parse('a&b=', { strictNullHandling: true }); +assert.deepEqual(parsedStrictNull, { a: null, b: '' }); +``` + +To completely skip rendering keys with `null` values, use the `skipNulls` flag: + +```javascript +var nullsSkipped = qs.stringify({ a: 'b', c: null}, { skipNulls: true }); +assert.equal(nullsSkipped, 'a=b'); +``` + +If you're communicating with legacy systems, you can switch to `iso-8859-1` +using the `charset` option: + +```javascript +var iso = qs.stringify({ æ: 'æ' }, { charset: 'iso-8859-1' }); +assert.equal(iso, '%E6=%E6'); +``` + +Characters that don't exist in `iso-8859-1` will be converted to numeric +entities, similar to what browsers do: + +```javascript +var numeric = qs.stringify({ a: '☺' }, { charset: 'iso-8859-1' }); +assert.equal(numeric, 'a=%26%239786%3B'); +``` + +You can use the `charsetSentinel` option to announce the character by +including an `utf8=✓` parameter with the proper encoding if the checkmark, +similar to what Ruby on Rails and others do when submitting forms. + +```javascript +var sentinel = qs.stringify({ a: '☺' }, { charsetSentinel: true }); +assert.equal(sentinel, 'utf8=%E2%9C%93&a=%E2%98%BA'); + +var isoSentinel = qs.stringify({ a: 'æ' }, { charsetSentinel: true, charset: 'iso-8859-1' }); +assert.equal(isoSentinel, 'utf8=%26%2310003%3B&a=%E6'); +``` + +### Dealing with special character sets + +By default the encoding and decoding of characters is done in `utf-8`, +and `iso-8859-1` support is also built in via the `charset` parameter. + +If you wish to encode querystrings to a different character set (i.e. +[Shift JIS](https://en.wikipedia.org/wiki/Shift_JIS)) you can use the +[`qs-iconv`](https://github.com/martinheidegger/qs-iconv) library: + +```javascript +var encoder = require('qs-iconv/encoder')('shift_jis'); +var shiftJISEncoded = qs.stringify({ a: 'こんにちは！' }, { encoder: encoder }); +assert.equal(shiftJISEncoded, 'a=%82%B1%82%F1%82%C9%82%BF%82%CD%81I'); +``` + +This also works for decoding of query strings: + +```javascript +var decoder = require('qs-iconv/decoder')('shift_jis'); +var obj = qs.parse('a=%82%B1%82%F1%82%C9%82%BF%82%CD%81I', { decoder: decoder }); +assert.deepEqual(obj, { a: 'こんにちは！' }); +``` + +### RFC 3986 and RFC 1738 space encoding + +RFC3986 used as default option and encodes ' ' to *%20* which is backward compatible. +In the same time, output can be stringified as per RFC1738 with ' ' equal to '+'. + +``` +assert.equal(qs.stringify({ a: 'b c' }), 'a=b%20c'); +assert.equal(qs.stringify({ a: 'b c' }, { format : 'RFC3986' }), 'a=b%20c'); +assert.equal(qs.stringify({ a: 'b c' }, { format : 'RFC1738' }), 'a=b+c'); +``` + +[1]: https://npmjs.org/package/qs +[2]: http://versionbadg.es/ljharb/qs.svg +[3]: https://api.travis-ci.org/ljharb/qs.svg +[4]: https://travis-ci.org/ljharb/qs +[5]: https://david-dm.org/ljharb/qs.svg +[6]: https://david-dm.org/ljharb/qs +[7]: https://david-dm.org/ljharb/qs/dev-status.svg +[8]: https://david-dm.org/ljharb/qs?type=dev +[9]: https://ci.testling.com/ljharb/qs.png +[10]: https://ci.testling.com/ljharb/qs +[11]: https://nodei.co/npm/qs.png?downloads=true&stars=true +[license-image]: http://img.shields.io/npm/l/qs.svg +[license-url]: LICENSE +[downloads-image]: http://img.shields.io/npm/dm/qs.svg +[downloads-url]: http://npm-stat.com/charts.html?package=qs diff --git a/node_modules/qs/dist/qs.js b/node_modules/qs/dist/qs.js new file mode 100644 index 0000000..17f4e60 --- /dev/null +++ b/node_modules/qs/dist/qs.js @@ -0,0 +1,782 @@ +(function(f){if(typeof exports==="object"&&typeof module!=="undefined"){module.exports=f()}else if(typeof define==="function"&&define.amd){define([],f)}else{var g;if(typeof window!=="undefined"){g=window}else if(typeof global!=="undefined"){g=global}else if(typeof self!=="undefined"){g=self}else{g=this}g.Qs = f()}})(function(){var define,module,exports;return (function(){function r(e,n,t){function o(i,f){if(!n[i]){if(!e[i]){var c="function"==typeof require&&require;if(!f&&c)return c(i,!0);if(u)return u(i,!0);var a=new Error("Cannot find module '"+i+"'");throw a.code="MODULE_NOT_FOUND",a}var p=n[i]={exports:{}};e[i][0].call(p.exports,function(r){var n=e[i][1][r];return o(n||r)},p,p.exports,r,e,n,t)}return n[i].exports}for(var u="function"==typeof require&&require,i=0;i -1) { + val = val.split(',');

The stream should not have an encoding set and is expected to +emit `Buffer` objects. + +## Examples + +### Simple Express example + +```js +var contentType = require('content-type') +var express = require('express') +var getRawBody = require('raw-body') + +var app = express() + +app.use(function (req, res, next) { + getRawBody(req, { + length: req.headers['content-length'], + limit: '1mb', + encoding: contentType.parse(req).parameters.charset + }, function (err, string) { + if (err) return next(err) + req.text = string + next() + }) +}) + +// now access req.text +``` + +### Simple Koa example + +```js +var contentType = require('content-type') +var getRawBody = require('raw-body') +var koa = require('koa') + +var app = koa() + +app.use(function * (next) { + this.text = yield getRawBody(this.req, { + length: this.req.headers['content-length'], + limit: '1mb', + encoding: contentType.parse(this.req).parameters.charset + }) + yield next +}) + +// now access this.text +``` + +### Using as a promise + +To use this library as a promise, simply omit the `callback` and a promise is +returned, provided that a global `Promise` is defined. + +```js +var getRawBody = require('raw-body') +var http = require('http') + +var server = http.createServer(function (req, res) { + getRawBody(req) + .then(function (buf) { + res.statusCode = 200 + res.end(buf.length + ' bytes submitted') + }) + .catch(function (err) { + res.statusCode = 500 + res.end(err.message) + }) +}) + +server.listen(3000) +``` + +### Using with TypeScript + +```ts +import * as getRawBody from 'raw-body'; +import * as http from 'http'; + +const server = http.createServer((req, res) => { + getRawBody(req) + .then((buf) => { + res.statusCode = 200; + res.end(buf.length + ' bytes submitted'); + }) + .catch((err) => { + res.statusCode = err.statusCode; + res.end(err.message); + }); +}); + +server.listen(3000); +``` + +## License + +[MIT](LICENSE) + +[npm-image]: https://img.shields.io/npm/v/raw-body.svg +[npm-url]: https://npmjs.org/package/raw-body +[node-version-image]: https://img.shields.io/node/v/raw-body.svg +[node-version-url]: https://nodejs.org/en/download/ +[travis-image]: https://img.shields.io/travis/stream-utils/raw-body/master.svg +[travis-url]: https://travis-ci.org/stream-utils/raw-body +[coveralls-image]: https://img.shields.io/coveralls/stream-utils/raw-body/master.svg +[coveralls-url]: https://coveralls.io/r/stream-utils/raw-body?branch=master +[downloads-image]: https://img.shields.io/npm/dm/raw-body.svg +[downloads-url]: https://npmjs.org/package/raw-body diff --git a/node_modules/raw-body/index.d.ts b/node_modules/raw-body/index.d.ts new file mode 100644 index 0000000..dcbbebd --- /dev/null +++ b/node_modules/raw-body/index.d.ts @@ -0,0 +1,87 @@ +import { Readable } from 'stream'; + +declare namespace getRawBody { + export type Encoding = string | true; + + export interface Options { + /** + * The expected length of the stream. + */ + length?: number | string | null; + /** + * The byte limit of the body.

Use [`buf.fill(0)`][] to initialize such +`Buffer` instances to zeroes. + +When using `Buffer.allocUnsafe()` to allocate new `Buffer` instances, +allocations under 4KB are, by default, sliced from a single pre-allocated +`Buffer`. This allows applications to avoid the garbage collection overhead of +creating many individually allocated Buffers. This approach improves both +performance and memory usage by eliminating the need to track and cleanup as +many `Persistent` objects. + +However, in the case where a developer may need to retain a small chunk of +memory from a pool for an indeterminate amount of time, it may be appropriate +to create an un-pooled Buffer instance using `Buffer.allocUnsafeSlow()` then +copy out the relevant bits. + +```js +// need to keep around a few small chunks of memory +const store = []; + +socket.on('readable', () => { + const data = socket.read(); + // allocate for retained data + const sb = Buffer.allocUnsafeSlow(10); + // copy the data into the new allocation + data.copy(sb, 0, 0, 10); + store.push(sb); +}); +``` + +Use of `Buffer.allocUnsafeSlow()` should be used only as a last resort *after* +a developer has observed undue memory retention in their applications. + +A `TypeError` will be thrown if `size` is not a number. + +### All the Rest + +The rest of the `Buffer` API is exactly the same as in node.js. +[See the docs](https://nodejs.org/api/buffer.html). + + +## Related links + +- [Node.js issue: Buffer(number) is unsafe](https://github.com/nodejs/node/issues/4660) +- [Node.js Enhancement Proposal: Buffer.from/Buffer.alloc/Buffer.zalloc/Buffer() soft-deprecate](https://github.com/nodejs/node-eps/pull/4) + +## Why is `Buffer` unsafe? + +Today, the node.js `Buffer` constructor is overloaded to handle many different argument +types like `String`, `Array`, `Object`, `TypedArrayView` (`Uint8Array`, etc.), +`ArrayBuffer`, and also `Number`. + +The API is optimized for convenience: you can throw any type at it, and it will try to do +what you want. + +Because the Buffer constructor is so powerful, you often see code like this: + +```js +// Convert UTF-8 strings to hex +function toHex (str) { + return new Buffer(str).toString('hex') +} +``` + +***But what happens if `toHex` is called with a `Number` argument?*** + +### Remote Memory Disclosure + +If an attacker can make your program call the `Buffer` constructor with a `Number` +argument, then they can make it allocate uninitialized memory from the node.js process. +This could potentially disclose TLS private keys, user data, or database passwords. + +When the `Buffer` constructor is passed a `Number` argument, it returns an +**UNINITIALIZED** block of memory of the specified `size`.

It's surprisingly common to forget to check the type of your variables in a +dynamically-typed language like JavaScript. + +Usually the consequences of assuming the wrong type is that your program crashes with an +uncaught exception. But the failure mode for forgetting to check the type of arguments to +the `Buffer` constructor is more catastrophic. + +Here's an example of a vulnerable service that takes a JSON payload and converts it to +hex: + +```js +// Take a JSON payload {str: "some string"} and convert it to hex +var server = http.createServer(function (req, res) { + var data = '' + req.setEncoding('utf8') + req.on('data', function (chunk) { + data += chunk + }) + req.on('end', function () { + var body = JSON.parse(data) + res.end(new Buffer(body.str).toString('hex')) + }) +}) + +server.listen(8080) +``` + +In this example, an http client just has to send: + +```json +{ + "str": 1000 +} +``` + +and it will get back 1,000 bytes of uninitialized memory from the server. + +This is a very serious bug. It's similar in severity to the +[the Heartbleed bug](http://heartbleed.com/) that allowed disclosure of OpenSSL process +memory by remote attackers. + + +### Which real-world packages were vulnerable? + +#### [`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht) + +[Mathias Buus](https://github.com/mafintosh) and I +([Feross Aboukhadijeh](http://feross.org/)) found this issue in one of our own packages, +[`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht). The bug would allow +anyone on the internet to send a series of messages to a user of `bittorrent-dht` and get +them to reveal 20 bytes at a time of uninitialized memory from the node.js process. + +Here's +[the commit](https://github.com/feross/bittorrent-dht/commit/6c7da04025d5633699800a99ec3fbadf70ad35b8) +that fixed it. We released a new fixed version, created a +[Node Security Project disclosure](https://nodesecurity.io/advisories/68), and deprecated all +vulnerable versions on npm so users will get a warning to upgrade to a newer version. + +#### [`ws`](https://www.npmjs.com/package/ws) + +That got us wondering if there were other vulnerable packages. Sure enough, within a short +period of time, we found the same issue in [`ws`](https://www.npmjs.com/package/ws), the +most popular WebSocket implementation in node.js. + +If certain APIs were called with `Number` parameters instead of `String` or `Buffer` as +expected, then uninitialized server memory would be disclosed to the remote peer. + +These were the vulnerable methods: + +```js +socket.send(number) +socket.ping(number) +socket.pong(number) +``` + +Here's a vulnerable socket server with some echo functionality: + +```js +server.on('connection', function (socket) { + socket.on('message', function (message) { + message = JSON.parse(message) + if (message.type === 'echo') { + socket.send(message.data) // send back the user's message + } + }) +}) +``` + +`socket.send(number)` called on the server, will disclose server memory. + +Here's [the release](https://github.com/websockets/ws/releases/tag/1.0.1) where the issue +was fixed, with a more detailed explanation. Props to +[Arnout Kazemier](https://github.com/3rd-Eden) for the quick fix. Here's the +[Node Security Project disclosure](https://nodesecurity.io/advisories/67). + + +### What's the solution? + +It's important that node.js offers a fast way to get memory otherwise performance-critical +applications would needlessly get a lot slower. + +But we need a better way to *signal our intent* as programmers. **When we want +uninitialized memory, we should request it explicitly.** + +Sensitive functionality should not be packed into a developer-friendly API that loosely +accepts many different types. This type of API encourages the lazy practice of passing +variables in without checking the type very carefully. + +#### A new API: `Buffer.allocUnsafe(number)` + +The functionality of creating buffers with uninitialized memory should be part of another +API. We propose `Buffer.allocUnsafe(number)`. This way, it's not part of an API that +frequently gets user input of all sorts of different types passed into it. + +```js +var buf = Buffer.allocUnsafe(16) // careful, uninitialized memory! + +// Immediately overwrite the uninitialized buffer with data from another buffer +for (var i = 0; i < buf.length; i++) { + buf[i] = otherBuf[i] +} +``` + + +### How do we fix node.js core? + +We sent [a PR to node.js core](https://github.com/nodejs/node/pull/4514) (merged as +`semver-major`) which defends against one case: + +```js +var str = 16 +new Buffer(str, 'utf8') +``` + +In this situation, it's implied that the programmer intended the first argument to be a +string, since they passed an encoding as a second argument. Today, node.js will allocate +uninitialized memory in the case of `new Buffer(number, encoding)`, which is probably not +what the programmer intended. + +But this is only a partial solution, since if the programmer does `new Buffer(variable)` +(without an `encoding` parameter) there's no way to know what they intended. If `variable` +is sometimes a number, then uninitialized memory will sometimes be returned. + +### What's the real long-term fix? + +We could deprecate and remove `new Buffer(number)` and use `Buffer.allocUnsafe(number)` when +we need uninitialized memory. But that would break 1000s of packages. + +~~We believe the best solution is to:~~ + +~~1. Change `new Buffer(number)` to return safe, zeroed-out memory~~ + +~~2. Create a new API for creating uninitialized Buffers. We propose: `Buffer.allocUnsafe(number)`~~ + +#### Update + +We now support adding three new APIs: + +- `Buffer.from(value)` - convert from any type to a buffer +- `Buffer.alloc(size)` - create a zero-filled buffer +- `Buffer.allocUnsafe(size)` - create an uninitialized buffer with given size + +This solves the core problem that affected `ws` and `bittorrent-dht` which is +`Buffer(variable)` getting tricked into taking a number argument. + +This way, existing code continues working and the impact on the npm ecosystem will be +minimal. Over time, npm maintainers can migrate performance-critical code to use +`Buffer.allocUnsafe(number)` instead of `new Buffer(number)`. + + +### Conclusion + +We think there's a serious design issue with the `Buffer` API as it exists today. It +promotes insecure software by putting high-risk functionality into a convenient API +with friendly "developer ergonomics". + +This wasn't merely a theoretical exercise because we found the issue in some of the +most popular npm packages. + +Fortunately, there's an easy fix that can be applied today. Use `safe-buffer` in place of +`buffer`. + +```js +var Buffer = require('safe-buffer').Buffer +``` + +Eventually, we hope that node.js core can switch to this new, safer behavior.

This means that these versions of Node.js will *not* receive any updates, even in case of security issues, so using these release lines should be avoided, if at all possible. + +What you would do in this case is to convert all `new Buffer()` or `Buffer()` calls to use `Buffer.alloc()` or `Buffer.from()`, in the following way: + +- For `new Buffer(number)`, replace it with `Buffer.alloc(number)`. +- For `new Buffer(string)` (or `new Buffer(string, encoding)`), replace it with `Buffer.from(string)` (or `Buffer.from(string, encoding)`). +- For all other combinations of arguments (these are much rarer), also replace `new Buffer(...arguments)` with `Buffer.from(...arguments)`. + +Note that `Buffer.alloc()` is also _faster_ on the current Node.js versions than +`new Buffer(size).fill(0)`, which is what you would otherwise need to ensure zero-filling. + +Enabling eslint rule [no-buffer-constructor](https://eslint.org/docs/rules/no-buffer-constructor) +or +[node/no-deprecated-api](https://github.com/mysticatea/eslint-plugin-node/blob/master/docs/rules/no-deprecated-api.md) +is recommended to avoid accidential unsafe Buffer API usage. + +There is also a [JSCodeshift codemod](https://github.com/joyeecheung/node-dep-codemod#dep005) +for automatically migrating Buffer constructors to `Buffer.alloc()` or `Buffer.from()`. +Note that it currently only works with cases where the arguments are literals or where the +constructor is invoked with two arguments. + +_If you currently support those older Node.js versions and dropping them would be a semver-major change +for you, or if you support older branches of your packages, consider using [Variant 2](#variant-2) +or [Variant 3](#variant-3) on older branches, so people using those older branches will also receive +the fix. That way, you will eradicate potential issues caused by unguarded Buffer API usage and +your users will not observe a runtime deprecation warning when running your code on Node.js 10._ + + +## Variant 2: Use a polyfill + +Utilize [safer-buffer](https://www.npmjs.com/package/safer-buffer) as a polyfill to support older +Node.js versions. + +You would take exacly the same steps as in [Variant 1](#variant-1), but with a polyfill +`const Buffer = require('safer-buffer').Buffer` in all files where you use the new `Buffer` api. + +Make sure that you do not use old `new Buffer` API — in any files where the line above is added, +using old `new Buffer()` API will _throw_. It will be easy to notice that in CI, though. + +Alternatively, you could use [buffer-from](https://www.npmjs.com/package/buffer-from) and/or +[buffer-alloc](https://www.npmjs.com/package/buffer-alloc) [ponyfills](https://ponyfill.com/) — +those are great, the only downsides being 4 deps in the tree and slightly more code changes to +migrate off them (as you would be using e.g. `Buffer.from` under a different name). If you need only +`Buffer.from` polyfilled — `buffer-from` alone which comes with no extra dependencies. + +_Alternatively, you could use [safe-buffer](https://www.npmjs.com/package/safe-buffer) — it also +provides a polyfill, but takes a different approach which has +[it's drawbacks](https://github.com/chalker/safer-buffer#why-not-safe-buffer). It will allow you +to also use the older `new Buffer()` API in your code, though — but that's arguably a benefit, as +it is problematic, can cause issues in your code, and will start emitting runtime deprecation +warnings starting with Node.js 10._ + +Note that in either case, it is important that you also remove all calls to the old Buffer +API manually — just throwing in `safe-buffer` doesn't fix the problem by itself, it just provides +a polyfill for the new API. I have seen people doing that mistake. + +Enabling eslint rule [no-buffer-constructor](https://eslint.org/docs/rules/no-buffer-constructor) +or +[node/no-deprecated-api](https://github.com/mysticatea/eslint-plugin-node/blob/master/docs/rules/no-deprecated-api.md) +is recommended. + +_Don't forget to drop the polyfill usage once you drop support for Node.js < 4.5.0._ + + +## Variant 3 — manual detection, with safeguards + +This is useful if you create Buffer instances in only a few places (e.g. one), or you have your own +wrapper around them. + +### Buffer(0) + +This special case for creating empty buffers can be safely replaced with `Buffer.concat([])`, which +returns the same result all the way down to Node.js 0.8.x. + +### Buffer(notNumber) + +Before: + +```js +var buf = new Buffer(notNumber, encoding); +``` + +After: + +```js +var buf; +if (Buffer.from && Buffer.from !== Uint8Array.from) { + buf = Buffer.from(notNumber, encoding); +} else { + if (typeof notNumber === 'number') + throw new Error('The "size" argument must be of type number.'); + buf = new Buffer(notNumber, encoding); +} +``` + +`encoding` is optional. + +Note that the `typeof notNumber` before `new Buffer` is required (for cases when `notNumber` argument is not +hard-coded) and _is not caused by the deprecation of Buffer constructor_ — it's exactly _why_ the +Buffer constructor is deprecated. Ecosystem packages lacking this type-check caused numereous +security issues — situations when unsanitized user input could end up in the `Buffer(arg)` create +problems ranging from DoS to leaking sensitive information to the attacker from the process memory. + +When `notNumber` argument is hardcoded (e.g. literal `"abc"` or `[0,1,2]`), the `typeof` check can +be omitted. + +Also note that using TypeScript does not fix this problem for you — when libs written in +`TypeScript` are used from JS, or when user input ends up there — it behaves exactly as pure JS, as +all type checks are translation-time only and are not present in the actual JS code which TS +compiles to. + +### Buffer(number) + +For Node.js 0.10.x (and below) support: + +```js +var buf; +if (Buffer.alloc) { + buf = Buffer.alloc(number); +} else { + buf = new Buffer(number); + buf.fill(0); +} +``` + +Otherwise (Node.js ≥ 0.12.x): + +```js +const buf = Buffer.alloc ?

Before Node.js 8, this buffer contained + *arbitrary memory* for performance reasons, which could include anything ranging from + program source code to passwords and encryption keys. +- `new Buffer('abc')` creates a `Buffer` that contains the UTF-8-encoded version of + the string `'abc'`. A second argument could specify another encoding: For example, + `new Buffer(string, 'base64')` could be used to convert a Base64 string into the original + sequence of bytes that it represents. +- There are several other combinations of arguments. + +This meant that, in code like `var buffer = new Buffer(foo);`, *it is not possible to tell +what exactly the contents of the generated buffer are* without knowing the type of `foo`. + +Sometimes, the value of `foo` comes from an external source. For example, this function +could be exposed as a service on a web server, converting a UTF-8 string into its Base64 form: + +``` +function stringToBase64(req, res) { + // The request body should have the format of `{ string: 'foobar' }` + const rawBytes = new Buffer(req.body.string) + const encoded = rawBytes.toString('base64') + res.end({ encoded: encoded }) +} +``` + +Note that this code does *not* validate the type of `req.body.string`: + +- `req.body.string` is expected to be a string. If this is the case, all goes well. +- `req.body.string` is controlled by the client that sends the request. +- If `req.body.string` is the *number* `50`, the `rawBytes` would be 50 bytes: + - Before Node.js 8, the content would be uninitialized + - After Node.js 8, the content would be `50` bytes with the value `0` + +Because of the missing type check, an attacker could intentionally send a number +as part of the request. Using this, they can either: + +- Read uninitialized memory. This **will** leak passwords, encryption keys and other + kinds of sensitive information. (Information leak) +- Force the program to allocate a large amount of memory. For example, when specifying + `500000000` as the input value, each request will allocate 500MB of memory. + This can be used to either exhaust the memory available of a program completely + and make it crash, or slow it down significantly.

Adding in `safe-buffer` _magically removes the lint warning_, but the behavior +remains identiсal to what we had before, and when launched on Node.js 6.x LTS — this dumps out +chunks of uninitialized memory. +_And this code will still emit runtime warnings on Node.js 10.x and above._ + +That was done by design. I first considered changing `safe-buffer`, prohibiting old API usage or +emitting warnings on it, but that significantly diverges from `safe-buffer` design. After some +discussion, it was decided to move my approach into a separate package, and _this is that separate +package_. + +This footgun is not imaginary — I observed top-downloaded packages doing that kind of thing, +«fixing» the lint warning by blindly including `safe-buffer` without any actual changes. + +Also in some cases, even if the API _was_ migrated to use of safe Buffer API — a random pull request +can bring unsafe Buffer API usage back to the codebase by adding new calls — and that could go +unnoticed even if you have a linter prohibiting that (becase of the reason stated above), and even +pass CI. _I also observed that being done in popular packages._ + +Some examples: + * [webdriverio](https://github.com/webdriverio/webdriverio/commit/05cbd3167c12e4930f09ef7cf93b127ba4effae4#diff-124380949022817b90b622871837d56cR31) + (a module with 548 759 downloads/month), + * [websocket-stream](https://github.com/maxogden/websocket-stream/commit/c9312bd24d08271687d76da0fe3c83493871cf61) + (218 288 d/m, fix in [maxogden/websocket-stream#142](https://github.com/maxogden/websocket-stream/pull/142)), + * [node-serialport](https://github.com/node-serialport/node-serialport/commit/e8d9d2b16c664224920ce1c895199b1ce2def48c) + (113 138 d/m, fix in [node-serialport/node-serialport#1510](https://github.com/node-serialport/node-serialport/pull/1510)), + * [karma](https://github.com/karma-runner/karma/commit/3d94b8cf18c695104ca195334dc75ff054c74eec) + (3 973 193 d/m, fix in [karma-runner/karma#2947](https://github.com/karma-runner/karma/pull/2947)), + * [spdy-transport](https://github.com/spdy-http2/spdy-transport/commit/5375ac33f4a62a4f65bcfc2827447d42a5dbe8b1) + (5 970 727 d/m, fix in [spdy-http2/spdy-transport#53](https://github.com/spdy-http2/spdy-transport/pull/53)). + * And there are a lot more over the ecosystem. + +I filed a PR at +[mysticatea/eslint-plugin-node#110](https://github.com/mysticatea/eslint-plugin-node/pull/110) to +partially fix that (for cases when that lint rule is used), but it is a semver-major change for +linter rules and presets, so it would take significant time for that to reach actual setups. +_It also hasn't been released yet (2018-03-20)._ + +Also, `safer-buffer` discourages the usage of `.allocUnsafe()`, which is often done by a mistake. +It still supports it with an explicit concern barier, by placing it under +`require('safer-buffer/dangereous')`. + +## But isn't throwing bad? + +Not really. It's an error that could be noticed and fixed early, instead of causing havoc later like +unguarded `new Buffer()` calls that end up receiving user input can do. + +This package affects only the files where `var Buffer = require('safer-buffer').Buffer` was done, so +it is really simple to keep track of things and make sure that you don't mix old API usage with that. +Also, CI should hint anything that you might have missed. + +New commits, if tested, won't land new usage of unsafe Buffer API this way. +_Node.js 10.x also deals with that by printing a runtime depecation warning._ + +### Would it affect third-party modules? + +No, unless you explicitly do an awful thing like monkey-patching or overriding the built-in `Buffer`. +Don't do that. + +### But I don't want throwing… + +That is also fine! + +Also, it could be better in some cases when you don't comprehensive enough test coverage. + +In that case — just don't override `Buffer` and use +`var SaferBuffer = require('safer-buffer').Buffer` instead. + +That way, everything using `Buffer` natively would still work, but there would be two drawbacks: + +* `Buffer.from`/`Buffer.alloc` won't be polyfilled — use `SaferBuffer.from` and + `SaferBuffer.alloc` instead. +* You are still open to accidentally using the insecure deprecated API — use a linter to catch that. + +Note that using a linter to catch accidential `Buffer` constructor usage in this case is strongly +recommended. `Buffer` is not overriden in this usecase, so linters won't get confused. + +## «Without footguns»? + +Well, it is still possible to do _some_ things with `Buffer` API, e.g. accessing `.buffer` property +on older versions and duping things from there.

The `req` is +the Node.js HTTP request and the `path` is a urlencoded path to send (urlencoded, +not the actual file-system path). + +#### Options + +##### acceptRanges + +Enable or disable accepting ranged requests, defaults to true. +Disabling this will not send `Accept-Ranges` and ignore the contents +of the `Range` request header. + +##### cacheControl + +Enable or disable setting `Cache-Control` response header, defaults to +true. Disabling this will ignore the `immutable` and `maxAge` options. + +##### dotfiles + +Set how "dotfiles" are treated when encountered. A dotfile is a file +or directory that begins with a dot ("."). Note this check is done on +the path itself without checking if the path actually exists on the +disk. If `root` is specified, only the dotfiles above the root are +checked (i.e. the root itself can be within a dotfile when when set +to "deny"). + + - `'allow'` No special treatment for dotfiles. + - `'deny'` Send a 403 for any request for a dotfile. + - `'ignore'` Pretend like the dotfile does not exist and 404. + +The default value is _similar_ to `'ignore'`, with the exception that +this default will not ignore the files within a directory that begins +with a dot, for backward-compatibility. + +##### end + +Byte offset at which the stream ends, defaults to the length of the file +minus 1. The end is inclusive in the stream, meaning `end: 3` will include +the 4th byte in the stream. + +##### etag + +Enable or disable etag generation, defaults to true. + +##### extensions + +If a given file doesn't exist, try appending one of the given extensions, +in the given order. By default, this is disabled (set to `false`). An +example value that will serve extension-less HTML files: `['html', 'htm']`. +This is skipped if the requested file already has an extension. + +##### immutable + +Enable or diable the `immutable` directive in the `Cache-Control` response +header, defaults to `false`. If set to `true`, the `maxAge` option should +also be specified to enable caching. The `immutable` directive will prevent +supported clients from making conditional requests during the life of the +`maxAge` option to check if the file has changed. + +##### index + +By default send supports "index.html" files, to disable this +set `false` or to supply a new index pass a string or an array +in preferred order. + +##### lastModified + +Enable or disable `Last-Modified` header, defaults to true. Uses the file +system's last modified value. + +##### maxAge + +Provide a max-age in milliseconds for http caching, defaults to 0. +This can also be a string accepted by the +[ms](https://www.npmjs.org/package/ms#readme) module. + +##### root + +Serve files relative to `path`. + +##### start + +Byte offset at which the stream starts, defaults to 0.

The file to serve will be determined by combining `req.url` +with the provided root directory. When a file is not found, instead of +sending a 404 response, this module will instead call `next()` to move on +to the next middleware, allowing for stacking and fall-backs. + +#### Options + +##### acceptRanges + +Enable or disable accepting ranged requests, defaults to true. +Disabling this will not send `Accept-Ranges` and ignore the contents +of the `Range` request header. + +##### cacheControl + +Enable or disable setting `Cache-Control` response header, defaults to +true. Disabling this will ignore the `immutable` and `maxAge` options. + +##### dotfiles + + Set how "dotfiles" are treated when encountered. A dotfile is a file +or directory that begins with a dot ("."). Note this check is done on +the path itself without checking if the path actually exists on the +disk. If `root` is specified, only the dotfiles above the root are +checked (i.e. the root itself can be within a dotfile when set +to "deny"). + + - `'allow'` No special treatment for dotfiles. + - `'deny'` Deny a request for a dotfile and 403/`next()`. + - `'ignore'` Pretend like the dotfile does not exist and 404/`next()`. + +The default value is similar to `'ignore'`, with the exception that this +default will not ignore the files within a directory that begins with a dot. + +##### etag + +Enable or disable etag generation, defaults to true. + +##### extensions + +Set file extension fallbacks. When set, if a file is not found, the given +extensions will be added to the file name and search for. The first that +exists will be served. Example: `['html', 'htm']`. + +The default value is `false`. + +##### fallthrough + +Set the middleware to have client errors fall-through as just unhandled +requests, otherwise forward a client error. The difference is that client +errors like a bad request or a request to a non-existent file will cause +this middleware to simply `next()` to your next middleware when this value +is `true`. When this value is `false`, these errors (even 404s), will invoke +`next(err)`. + +Typically `true` is desired such that multiple physical directories can be +mapped to the same web address or for routes to fill in non-existent files. + +The value `false` can be used if this middleware is mounted at a path that +is designed to be strictly a single file system directory, which allows for +short-circuiting 404s for less overhead. This middleware will also reply to +all methods. + +The default value is `true`. + +##### immutable + +Enable or disable the `immutable` directive in the `Cache-Control` response +header, defaults to `false`. If set to `true`, the `maxAge` option should +also be specified to enable caching. The `immutable` directive will prevent +supported clients from making conditional requests during the life of the +`maxAge` option to check if the file has changed. + +##### index + +By default this module will send "index.html" files in response to a request +on a directory. To disable this set `false` or to supply a new index pass a +string or an array in preferred order. + +##### lastModified + +Enable or disable `Last-Modified` header, defaults to true. Uses the file +system's last modified value. + +##### maxAge + +Provide a max-age in milliseconds for http caching, defaults to 0. This +can also be a string accepted by the [ms](https://www.npmjs.org/package/ms#readme) +module. + +##### redirect + +Redirect to trailing "/" when the pathname is a dir. Defaults to `true`. + +##### setHeaders + +Function to set custom headers on response. Alterations to the headers need to +occur synchronously. The function is called as `fn(res, path, stat)`, where +the arguments are: + + - `res` the response object + - `path` the file path that is being sent + - `stat` the stat object of the file that is being sent + +## Examples + +### Serve files with vanilla node.js http server + +```js +var finalhandler = require('finalhandler') +var http = require('http') +var serveStatic = require('serve-static') + +// Serve up public/ftp folder +var serve = serveStatic('public/ftp', { 'index': ['index.html', 'index.htm'] }) + +// Create server +var server = http.createServer(function onRequest (req, res) { + serve(req, res, finalhandler(req, res)) +}) + +// Listen +server.listen(3000) +``` + +### Serve all files as downloads + +```js +var contentDisposition = require('content-disposition') +var finalhandler = require('finalhandler') +var http = require('http') +var serveStatic = require('serve-static') + +// Serve up public/ftp folder +var serve = serveStatic('public/ftp', { + 'index': false, + 'setHeaders': setHeaders +}) + +// Set header to force download +function setHeaders (res, path) { + res.setHeader('Content-Disposition', contentDisposition(path)) +} + +// Create server +var server = http.createServer(function onRequest (req, res) { + serve(req, res, finalhandler(req, res)) +}) + +// Listen +server.listen(3000) +``` + +### Serving using express + +#### Simple + +This is a simple example of using Express. + +```js +var express = require('express') +var serveStatic = require('serve-static') + +var app = express() + +app.use(serveStatic('public/ftp', { 'index': ['default.html', 'default.htm'] })) +app.listen(3000) +``` + +#### Multiple roots + +This example shows a simple way to search through multiple directories. +Files are look for in `public-optimized/` first, then `public/` second as +a fallback. + +```js +var express = require('express') +var path = require('path') +var serveStatic = require('serve-static') + +var app = express() + +app.use(serveStatic(path.join(__dirname, 'public-optimized'))) +app.use(serveStatic(path.join(__dirname, 'public'))) +app.listen(3000) +``` + +#### Different settings for paths + +This example shows how to set a different max age depending on the served +file type.

If the request has no body, +even if there is a `Content-Type` header, then `null` is returned. If the +`Content-Type` header is invalid or does not matches any of the `types`, then +`false` is returned. Otherwise, a string of the type that matched is returned. + +The `request` argument is expected to be a Node.js HTTP request.

Conversions are still accurate as we make use of BigInt in the conversion process, but in the case of `unsigned long long` we simply cannot represent some possible output values in JavaScript. For example, converting the JavaScript number `-1` to a Web IDL `unsigned long long` is supposed to produce the Web IDL value `18446744073709551615`. Since we are representing our Web IDL values in JavaScript, we can't represent `18446744073709551615`, so we instead the best we could do is `18446744073709551616` as the output. + +To mitigate this, we could return the raw BigInt value from the conversion function, but right now it is not implemented. If your use case requires such precision, [file an issue](https://github.com/jsdom/webidl-conversions/issues/new). + +On the other hand, `long long` conversion is always accurate, since the input value can never be more precise than the output value. + +### A note on `BufferSource` types + +All of the `BufferSource` types will throw when the relevant `ArrayBuffer` has been detached. This technically is not part of the [specified conversion algorithm](https://heycam.github.io/webidl/#es-buffer-source-types), but instead part of the [getting a reference/getting a copy](https://heycam.github.io/webidl/#ref-for-dfn-get-buffer-source-reference%E2%91%A0) algorithms. We've consolidated them here for convenience and ease of implementation, but if there is a need to separate them in the future, please open an issue so we can investigate. + +## Background + +What's actually going on here, conceptually, is pretty weird. Let's try to explain. + +Web IDL, as part of its madness-inducing design, has its own type system. When people write algorithms in web platform specs, they usually operate on Web IDL values, i.e. instances of Web IDL types. For example, if they were specifying the algorithm for our `doStuff` operation above, they would treat `x` as a Web IDL value of [Web IDL type `boolean`](http://heycam.github.io/webidl/#idl-boolean). Crucially, they would _not_ treat `x` as a JavaScript variable whose value is either the JavaScript `true` or `false`. They're instead working in a different type system altogether, with its own rules. + +Separately from its type system, Web IDL defines a ["binding"](http://heycam.github.io/webidl/#ecmascript-binding) of the type system into JavaScript. This contains rules like: when you pass a JavaScript value to the JavaScript method that manifests a given Web IDL operation, how does that get converted into a Web IDL value? For example, a JavaScript `true` passed in the position of a Web IDL `boolean` argument becomes a Web IDL `true`. But, a JavaScript `true` passed in the position of a [Web IDL `unsigned long`](http://heycam.github.io/webidl/#idl-unsigned-long) becomes a Web IDL `1`. And so on. + +Finally, we have the actual implementation code. This is usually C++, although these days [some smart people are using Rust](https://github.com/servo/servo). The implementation, of course, has its own type system. So when they implement the Web IDL algorithms, they don't actually use Web IDL values, since those aren't "real" outside of specs. Instead, implementations apply the Web IDL binding rules in such a way as to convert incoming JavaScript values into C++ values. For example, if code in the browser called `doStuff(true, true)`, then the implementation code would eventually receive a C++ `bool` containing `true` and a C++ `uint32_t` containing `1`. + +The upside of all this is that implementations can abstract all the conversion logic away, letting Web IDL handle it, and focus on implementing the relevant methods in C++ with values of the correct type already provided. That is payoff of Web IDL, in a nutshell. + +And getting to that payoff is the goal of _this_ project—but for JavaScript implementations, instead of C++ ones. That is, this library is designed to make it easier for JavaScript developers to write functions that behave like a given Web IDL operation. So conceptually, the conversion pipeline, which in its general form is JavaScript values ↦ Web IDL values ↦ implementation-language values, in this case becomes JavaScript values ↦ Web IDL values ↦ JavaScript values. And that intermediate step is where all the logic is performed: a JavaScript `true` becomes a Web IDL `1` in an unsigned long context, which then becomes a JavaScript `1`. + +## Don't use this + +Seriously, why would you ever use this? You really shouldn't. Web IDL is … strange, and you shouldn't be emulating its semantics. If you're looking for a generic argument-processing library, you should find one with better rules than those from Web IDL. In general, your JavaScript should not be trying to become more like Web IDL; if anything, we should fix Web IDL to make it more like JavaScript. + +The _only_ people who should use this are those trying to create faithful implementations (or polyfills) of web platform interfaces defined in Web IDL. Its main consumer is the [jsdom](https://github.com/jsdom/jsdom) project. diff --git a/node_modules/webidl-conversions/lib/index.js b/node_modules/webidl-conversions/lib/index.js new file mode 100644 index 0000000..71d394a --- /dev/null +++ b/node_modules/webidl-conversions/lib/index.js @@ -0,0 +1,489 @@ +"use strict"; + +function makeException(ErrorType, message, opts = {}) { + if (opts.globals) { + ErrorType = opts.globals[ErrorType.name]; + } + return new ErrorType(`${opts.context ? opts.context : "Value"} ${message}.`); +} + +function toNumber(value, opts = {}) { + if (!opts.globals) { + return +value; + } + if (typeof value === "bigint") { + throw opts.globals.TypeError("Cannot convert a BigInt value to a number"); + } + return opts.globals.Number(value); +} + +function type(V) { + if (V === null) { + return "Null"; + } + switch (typeof V) { + case "undefined": + return "Undefined"; + case "boolean": + return "Boolean"; + case "number": + return "Number"; + case "string": + return "String"; + case "symbol": + return "Symbol"; + case "bigint": + return "BigInt"; + case "object": + // Falls through + case "function": + // Falls through + default: + // Per ES spec, typeof returns an implemention-defined value that is not any of the existing ones for + // uncallable non-standard exotic objects.
