| [](https://the-convocation.github.io/twitter-scraper/) | ||
|
|
||
| A port of [n0madic/twitter-scraper](https://github.com/n0madic/twitter-scraper) | ||
| to Node.js. | ||
|
|
||
| > Twitter's API is annoying to work with, and has lots of limitations — luckily | ||
| > their frontend (JavaScript) has it's own API, which I reverse-engineered. No | ||
| > API rate limits. No tokens needed. No restrictions. Extremely fast. | ||
| > | ||
| > You can use this library to get the text of any user's Tweets trivially. | ||
| Known limitations: | ||
|
|
||
| - Search operations require logging in with a real user account via | ||
| `scraper.login()`. | ||
| - Twitter's frontend API does in fact have rate limits | ||
| ([#11](https://github.com/the-convocation/twitter-scraper/issues/11)) | ||
| This is a modified version of [@the-convocation/twitter-scraper](https://github.com/the-convocation/twitter-scraper) with added functionality for sending tweets and retweets. This package does not require Twitter API to use, and will run in both the browser and server. | ||
|
|
||
| ## Installation | ||
|
|
||
| This package requires Node.js v16.0.0 or greater. | ||
|
|
||
| NPM: | ||
|
|
||
| ```sh | ||
| npm install @the-convocation/twitter-scraper | ||
| ``` | ||
|
|
||
| Yarn: | ||
|
|
||
| ```sh | ||
| yarn add @the-convocation/twitter-scraper | ||
| ``` | ||
|
|
||
| TypeScript types have been bundled with the distribution. | ||
|
|
||
| ## Usage | ||
|
|
||
| Most use cases are exactly the same as in | ||
| [n0madic/twitter-scraper](https://github.com/n0madic/twitter-scraper). Channel | ||
| iterators have been translated into | ||
| [AsyncGenerator](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/AsyncGenerator) | ||
| instances, and can be consumed with the corresponding | ||
| `for await (const x of y) { ... }` syntax. | ||
|
|
||
| ### Browser usage | ||
|
|
||
| This package directly invokes the Twitter API, which does not have permissive | ||
| CORS headers. With the default settings, requests will fail unless you disable | ||
| CORS checks, which is not advised. Instead, applications must provide a CORS | ||
| proxy and configure it in the `Scraper` options. | ||
|
|
||
| Proxies (and other request mutations) can be configured with the request | ||
| interceptor transform: | ||
|
|
||
| ```ts | ||
| const scraper = new Scraper({ | ||
| transform: { | ||
| request(input: RequestInfo | URL, init?: RequestInit) { | ||
| // The arguments here are the same as the parameters to fetch(), and | ||
| // are kept as-is for flexibility of both the library and applications. | ||
| if (input instanceof URL) { | ||
| const proxy = "https://corsproxy.io/?" + | ||
| encodeURIComponent(input.toString()); | ||
| return [proxy, init]; | ||
| } else if (typeof input === "string") { | ||
| const proxy = "https://corsproxy.io/?" + encodeURIComponent(input); | ||
| return [proxy, init]; | ||
| } else { | ||
| // Omitting handling for example | ||
| throw new Error("Unexpected request input type"); | ||
| } | ||
| }, | ||
| }, | ||
| }); | ||
| ``` | ||
|
|
||
| [corsproxy.io](https://corsproxy.io) is a public CORS proxy that works correctly | ||
| with this package. | ||
|
|
||
| The public CORS proxy [corsproxy.org](https://corsproxy.org) _does not work_ at | ||
| the time of writing (at least not using their recommended integration on the | ||
| front page). | ||
|
|
||
| #### Next.js 13.x example: | ||
|
|
||
| ```tsx | ||
| "use client"; | ||
|
|
||
| import { Scraper, Tweet } from "@the-convocation/twitter-scraper"; | ||
| import { useEffect, useMemo, useState } from "react"; | ||
|
|
||
| export default function Home() { | ||
| const scraper = useMemo( | ||
| () => | ||
| new Scraper({ | ||
| transform: { | ||
| request(input: RequestInfo | URL, init?: RequestInit) { | ||
| if (input instanceof URL) { | ||
| const proxy = "https://corsproxy.io/?" + | ||
| encodeURIComponent(input.toString()); | ||
| return [proxy, init]; | ||
| } else if (typeof input === "string") { | ||
| const proxy = "https://corsproxy.io/?" + | ||
| encodeURIComponent(input); | ||
| return [proxy, init]; | ||
| } else { | ||
| throw new Error("Unexpected request input type"); | ||
| } | ||
| }, | ||
| }, | ||
| }), | ||
| [], | ||
| ); | ||
| const [tweet, setTweet] = useState<Tweet | null>(null); | ||
|
|
||
| useEffect(() => { | ||
| async function getTweet() { | ||
| const latestTweet = await scraper.getLatestTweet("twitter"); | ||
| if (latestTweet) { | ||
| setTweet(latestTweet); | ||
| } | ||
| } | ||
|
|
||
| getTweet(); | ||
| }, [scraper]); | ||
|
|
||
| return ( | ||
| <main className="flex min-h-screen flex-col items-center justify-between p-24"> | ||
| {tweet?.text} | ||
| </main> | ||
| ); | ||
| } | ||
| ``` | ||
|
|
||
| ### Edge runtimes | ||
|
|
||
| This package currently uses | ||
| [`cross-fetch`](https://www.npmjs.com/package/cross-fetch) as a portable | ||
| `fetch`. Edge runtimes such as CloudFlare Workers sometimes have `fetch` | ||
| functions that behave differently from the web standard, so you may need to | ||
| override the `fetch` function the scraper uses. If so, a custom `fetch` can be | ||
| provided in the options: | ||
|
|
||
| ```ts | ||
| const scraper = new Scraper({ | ||
| fetch: fetch, | ||
| }); | ||
| npm install agent-twitter-client | ||
| ``` | ||
|
|
||
| Note that this does not change the arguments passed to the function, or the | ||
| expected return type. If the custom `fetch` function produces runtime errors | ||
| related to incorrect types, be sure to wrap it in a shim (not currently | ||
| supported directly by interceptors): | ||
|
|
||
| ```ts | ||
| const scraper = new Scraper({ | ||
| fetch: (input, init) => { | ||
| // Transform input and init into your function's expected types... | ||
| return fetch(input, init) | ||
| .then((res) => { | ||
| // Transform res into a web-compliant response... | ||
| return res; | ||
| }); | ||
| }, | ||
| }); | ||
| ``` | ||
|
|

|
||
| ### Setup | ||
|
|
||
| This project currently requires Node 18.x for development and uses Yarn for | ||
| package management. | ||
| [Corepack](https://nodejs.org/dist/latest-v18.x/docs/api/corepack.html) is | ||
| configured for this project, so you don't need to install a particular package | ||
| manager version manually. | ||
|
|
||
| > The project supports Node 16.x at runtime, but requires Node 18.x to run its | ||
| > build tools. | ||
| Just run `corepack enable` to turn on the shims, then run `yarn` to install the | ||
| dependencies. | ||
|
|
||
| #### Basic scripts | ||
|
|
||
| - `yarn build`: Builds the project into the `dist` folder | ||
| - `yarn test`: Runs the package tests (see [Testing](#testing) first) | ||
|
|
||
| Run `yarn help` for general `yarn` usage information. | ||
|
|
||
| ### Testing | ||
|
|
||
| This package includes unit tests for all major functionality. Given the speed at | ||
| which Twitter's private API changes, failing tests are to be expected. | ||
|
|
||
| ```sh | ||
| yarn test | ||
| ``` | ||
|
|
||
| Before running tests, you should configure environment variables for | ||
| authentication. | ||
| Configure environment variables for authentication. | ||
|
|
||
| ``` | ||
| TWITTER_USERNAME= # Account username | ||
| TWITTER_PASSWORD= # Account password | ||
| TWITTER_EMAIL= # Account email | ||
| TWITTER_COOKIES= # JSON-serialized array of cookies of an authenticated session | ||
| PROXY_URL= # HTTP(s) proxy for requests (optional) | ||
| ``` | ||
|
|
||
| ### Commit message format | ||
|
|
||
| We use [Conventional Commits](https://www.conventionalcommits.org), and enforce | ||
| this with precommit checks. Please refer to the Git history for real examples of | ||
| the commit message format. | ||
