API changes between v0.6 and v0.8

When editing this page please be as detailed as possible. Examples are encouraged!

Deprecated:

• http.Client()
• path.{exists,existsSync} was moved to fs.{exists,existsSync}
• tty.setRawMode(mode) was moved to tty.ReadStream#setRawMode() (i.e. process.stdin.setRawMode())
• Direct use of ev_* and eio_* functions is deprecated. Please use the methods provided by libuv instead. For help porting from eio_custom to uv_queue_work, see this wiki page. For help porting from ev_io_* to uv_poll_*, see this wiki page.

Removed:

• waf build system - node.js will be using gyp now
  • If you are a native module author(you may still be one if you're not on this list), migrate to node-gyp ASAP!
• require('sys') throws, use require('util') now. The "sys" module was deprecated in node v0.4.
• process.installPrefix has been removed (#3483). process.installPrefix was (accidentally) always undefined in node v0.6.
• node --vars has been removed (#3483). node --vars always (accidentally) has empty output in node v0.6

Changed:

• process

  • process.stdin.on('keypress') will not be emitted by default, as it's an internal API. Use the keypress module now.
  • process.stdin.pipe(dest) will automatically call process.stdin.resume().

• cluster

  • cluster.fork() no longer return a child_process.fork() object use cluster.fork().process to get the object.
  • the 'death' event on the cluster object is renamed to 'exit'.
  • the kill() method is renamed to destroy().
  • the CLUSTER_WORKER_ID env is now called CLUSTER_UNIQUE_ID, but you should not have used that anyway.
  • workers now kill themselves when they accidentally lose their connection to the master.

• http

  • http.Server emits 'connect' event instead of 'upgrade' when the CONNECT method is requested.
  • http.ServerResponse sends Date: header by default. You can disable it by setting response.sendDate to false.
  • http.ClientRequest emits 'connect' event instead of 'request' when the CONNECT method is responded.

• net

  • net.listen(socketPath) no longer unlinks the socket unless you call server.close(). Automatic unlinking was subject to race conditions in multi-process setups. Also applies to http.listen(socketPath).

• child_process

  • arguments and options arguments of child_process.fork() became an option.
  • the 'exit' event is now emitted right after the child process exits. It no longer waits for all stdio pipes to be closed.
  • the 'close' event was added that has is emitted after the child has exited and all the stdio pipes are closed.

• readline

  • arguments of rl.createInterface became an option as rl.createInterface(options) but still took an old style as rl.createInterface(input, output, completer)

• url

  • url.parse() now parses IPv6 addresses.
  • url.parse() now escapes delimiters characters rather than truncating the input.
  • url.format() now escapes the auth section, and url.parse() decodes it.

• fs

  • path.exists() and path.existsSync() has moved to fs.exists() and fs.existsSync().
  • fs.symlink type argument can now be 'junction' (for Windows only).
  • fs.realpath and fs.lstat work the same on Windows as on Unix

• console

  • console.timeEnd now throws when there's no such label

• buffer

  • SlowBuffer now inherits from Buffer. So if you have a module that modifies the prototype, now you only need to alter Buffer.prototype.

• os

  • os.cpus().times is now supported on Windows
  • os.uptime now displays the correct uptime if the system's current uptime is > 50 days on Windows

Added:

• buffer

  • 'utf16le' encoding.

• child_process

  • silent option to child_process.fork() - stdout and stderr won't be shared with parent.
  • .disconnect() when using child_process.fork() this will allow the child to die gracefully.
  • stdio option for child_process.spawn() - configuration of child's stdio (file descriptors).
  • detached option for child_process.spawn() - make the child a process group leader (see docs)
  • child.send() can now send net.Server and net.Socket as second argument.

• cluster

  • 'fork', 'online', 'listening', and 'setup' events.
  • Worker object which is provided from cluster.workers (in the master) or cluster.worker (in the worker).
  • env optional argument to cluster.fork().
  • cluster.setupMaster() and cluster.settings.
  • cluster.disconnect() and worker.disconnect().
  • worker.id what there before was internally known as workerID.
  • worker.suicide flag set when worker disconnect or die, indicate if this was an accidental death.

• crypto

  • crypto.getDiffieHellman().
  • cipher.setAutoPadding() and decipher.setAutoPadding().
  • ciphers option to crypto.createCredentials().

• domain

  • see http://nodejs.org/docs/v0.8.0/api/domain.html

• fs

  • fs.appendFile() and fs.appendFileSync().
  • wx, wx+, ax, and ax+ modes to fs.open() and fs.openSync().

• http

  • callback optional argument to server.close().
  • sendDate property to http.ServerResponse.
  • http.request() and http.get() can accept as their argument a url that is parsed with url.parse()

• https

  • ciphers, rejectUnauthorized option to https.request() and https.get().

• net

  • net.connect(options, [connectionListener]).
  • callback optional argument to server.close().
  • server.listen({ fd: someNumber }) to listen on arbitrary file descriptors.

• process

  • process.abort().
  • process.hrtime(), hi-res timer with up to nanosecond granularity.

• querystring

  • querystring.parse(str, [sep], [eq], [options]), limited to 1000 parameters by default.

• stream

  • 'utf16le' and 'ucs2' encoding to setEncoding().

• tls

  • tls.CLIENT_RENEG_LIMIT and tls.CLIENT_RENEG_WINDOW to mitigate session renegotiation attacks
  • tls.connect(options, [secureConnectionListener]).
  • ciphers, rejectUnauthorized and socket options to tls.connect().
  • cleartextStream.getCipher() was added in the api doc and open to the public.

• zlib

  • dictionary option.
