#twit Twitter API Client for node Supports both the **REST** and **Streaming** API. #Installing ``` npm install twit ``` ##Usage: ```javascript var Twit = require('twit') var T = new Twit({ consumer_key: '...' , consumer_secret: '...' , access_token: '...' , access_token_secret: '...' }) // // tweet 'hello world!' // T.post('statuses/update', { status: 'hello world!' }, function(err, data, response) { console.log(data) }) // // search twitter for all tweets containing the word 'banana' since Nov. 11, 2011 // T.get('search/tweets', { q: 'banana since:2011-11-11', count: 100 }, function(err, data, response) { console.log(data) }) // // get the list of user id's that follow @tolga_tezel // T.get('followers/ids', { screen_name: 'tolga_tezel' }, function (err, data, response) { console.log(data) }) // // retweet a tweet with id '343360866131001345' // T.post('statuses/retweet/:id', { id: '343360866131001345' }, function (err, data, response) { console.log(data) }) // // destroy a tweet with id '343360866131001345' // T.post('statuses/destroy/:id', { id: '343360866131001345' }, function (err, data, response) { console.log(data) }) // // get `funny` twitter users // T.get('users/suggestions/:slug', { slug: 'funny' }, function (err, data, response) { console.log(data) }) // // post a tweet with media // var b64content = fs.readFileSync('/path/to/img', { encoding: 'base64' }) // first we must post the media to Twitter T.post('media/upload', { media_data: b64content }, function (err, data, response) { // now we can reference the media and post a tweet (media will attach to the tweet) var mediaIdStr = data.media_id_string var params = { status: 'loving life #nofilter', media_ids: [mediaIdStr] } T.post('statuses/update', params, function (err, data, response) { console.log(data) }) }) // // stream a sample of public statuses // var stream = T.stream('statuses/sample') stream.on('tweet', function (tweet) { console.log(tweet) }) // // filter the twitter public stream by the word 'mango'. // var stream = T.stream('statuses/filter', { track: 'mango' }) stream.on('tweet', function (tweet) { console.log(tweet) }) // // filter the public stream by the latitude/longitude bounded box of San Francisco // var sanFrancisco = [ '-122.75', '36.8', '-121.75', '37.8' ] var stream = T.stream('statuses/filter', { locations: sanFrancisco }) stream.on('tweet', function (tweet) { console.log(tweet) }) // // filter the public stream by english tweets containing `#apple` // var stream = T.stream('statuses/filter', { track: '#apple', language: 'en' }) stream.on('tweet', function (tweet) { console.log(tweet) }) ``` # twit API: ##`var T = new Twit(config)` Create a `Twit` instance that can be used to make requests to Twitter's APIs. If authenticating with user context, `config` should be an object of the form: ``` { consumer_key: '...' , consumer_secret: '...' , access_token: '...' , access_token_secret: '...' } ``` If authenticating with application context, `config` should be an object of the form: ``` { consumer_key: '...' , consumer_secret: '...' , app_only_auth: true } ``` Note that Application-only auth will not allow you to perform requests to API endpoints requiring a user context, such as posting tweets. However, the endpoints available can have a higher rate limit. ##`T.get(path, [params], callback)` GET any of the REST API endpoints. **path** The endpoint to hit. When specifying `path` values, omit the **'.json'** at the end (i.e. use **'search/tweets'** instead of **'search/tweets.json'**). **params** (Optional) parameters for the request. **callback** `function (err, data, response)` - `data` is the parsed data received from Twitter. - `response` is the [http.IncomingMessage](http://nodejs.org/api/http.html#http_http_incomingmessage) received from Twitter. ##`T.post(path, [params], callback)` POST any of the REST API endpoints. Same usage as `T.get()`. ##`T.getAuth()` Get the client's authentication tokens. ##`T.setAuth(tokens)` Update the client's authentication tokens. ##`T.stream(path, [params])` Use this with the Streaming API. **path** Streaming endpoint to hit. One of: - **'statuses/filter'** - **'statuses/sample'** - **'statuses/firehose'** - **'user'** - **'site'** For a description of each Streaming endpoint, see the [Twitter API docs](https://dev.twitter.com/docs/api/1.1#334). **params** (Optional) parameters for the request. Any Arrays passed in `params` get converted to comma-separated strings, allowing you to do requests like: ```javascript // // I only want to see tweets about my favorite fruits // // same result as doing { track: 'bananas,oranges,strawberries' } var stream = T.stream('statuses/filter', { track: ['bananas', 'oranges', 'strawberries'] }) stream.on('tweet', function (tweet) { //... }) ``` # Using the Streaming API `T.stream(path, [params])` keeps the connection alive, and returns an `EventEmitter`. The following events are emitted: ##event: 'message' Emitted each time an object is received in the stream. This is a catch-all event that can be used to process any data received in the stream, rather than using the more specific events documented below. New in version 2.1.0. ```javascript stream.on('message', function (msg) { //... }) ``` ##event: 'tweet' Emitted each time a status (tweet) comes into the stream. ```javascript stream.on('tweet', function (tweet) { //... }) ``` ##event: 'delete' Emitted each time a status (tweet) deletion message comes into the stream. ```javascript stream.on('delete', function (deleteMessage) { //... }) ``` ##event: 'limit' Emitted each time a limitation message comes into the stream. ```javascript stream.on('limit', function (limitMessage) { //... }) ``` ##event: 'scrub_geo' Emitted each time a location deletion message comes into the stream. ```javascript stream.on('scrub_geo', function (scrubGeoMessage) { //... }) ``` ##event: 'disconnect' Emitted when a disconnect message comes from Twitter. This occurs if you have multiple streams connected to Twitter's API. Upon receiving a disconnect message from Twitter, `Twit` will close the connection and emit this event with the message details received from twitter. ```javascript stream.on('disconnect', function (disconnectMessage) { //... }) ``` ##event: 'connect' Emitted when a connection attempt is made to Twitter. The http `request` object is emitted. ```javascript stream.on('connect', function (request) { //... }) ``` ##event: 'connected' Emitted when the response is received from Twitter. The http `response` object is emitted. ```javascript stream.on('connected', function (response) { //... }) ``` ##event: 'reconnect' Emitted when a reconnection attempt to Twitter is scheduled. If Twitter is having problems or we get rate limited, we schedule a reconnect according to Twitter's [reconnection guidelines](https://dev.twitter.com/docs/streaming-apis/connecting). The last http `request` and `response` objects are emitted, along with the time (in milliseconds) left before the reconnect occurs. ```javascript stream.on('reconnect', function (request, response, connectInterval) { //... }) ``` ##event: 'warning' This message is appropriate for clients using high-bandwidth connections, like the firehose. If your connection is falling behind, Twitter will queue messages for you, until your queue fills up, at which point they will disconnect you. ```javascript stream.on('warning', function (warning) { //... }) ``` ##event: 'status_withheld' Emitted when Twitter sends back a `status_withheld` message in the stream. This means that a tweet was withheld in certain countries. ```javascript stream.on('status_withheld', function (withheldMsg) { //... }) ``` ##event: 'user_withheld' Emitted when Twitter sends back a `user_withheld` message in the stream. This means that a Twitter user was withheld in certain countries. ```javascript stream.on('user_withheld', function (withheldMsg) { //... }) ``` ##event: 'friends' Emitted when Twitter sends the ["friends" preamble](https://dev.twitter.com/docs/streaming-apis/messages#User_stream_messages) when connecting to a user stream. This message contains a list of the user's friends, represented as an array of user ids. ```javascript stream.on('friends', function (friendsMsg) { //... }) ``` ##event: 'direct_message' Emitted when a direct message is sent to the user. Unfortunately, Twitter has not documented this event for user streams. ```javascript stream.on('direct_message', function (directMsg) { //... }) ``` ##event: 'user_event' Emitted when Twitter sends back a [User stream event](https://dev.twitter.com/docs/streaming-apis/messages#User_stream_messages). See the Twitter docs for more information on each event's structure. ```javascript stream.on('user_event', function (eventMsg) { //... }) ``` In addition, the following user stream events are provided for you to listen on: * `blocked` * `unblocked` * `favorite` * `unfavorite` * `follow` * `unfollow` * `user_update` * `list_created` * `list_destroyed` * `list_updated` * `list_member_added` * `list_member_removed` * `list_user_subscribed` * `list_user_unsubscribed` * `unknown_user_event` (for an event that doesn't match any of the above) ###Example: ```javascript stream.on('favorite', function (event) { //... }) ``` ##event: 'error' Emitted when an API request or response error occurs. An `Error` object is emitted, with properties: ```js { message: '...', // error message statusCode: '...', // statusCode from Twitter code: '...', // error code from Twitter twitterReply: '...', // raw response data from Twitter allErrors: '...' // array of errors returned from Twitter } ``` ##stream.stop() Call this function on the stream to stop streaming (closes the connection with Twitter). ##stream.start() Call this function to restart the stream after you called `.stop()` on it. Note: there is no need to call `.start()` to begin streaming. `Twit.stream` calls `.start()` for you. ------- #What do I have access to? Anything in the Twitter API: * REST API Endpoints: https://dev.twitter.com/docs/api * Public stream endpoints: https://dev.twitter.com/docs/streaming-api/methods * User stream endpoints: https://dev.twitter.com/docs/streaming-api/user-streams * Site stream endpoints: https://dev.twitter.com/docs/streaming-api/site-streams ------- Go here to create an app and get OAuth credentials (if you haven't already): https://dev.twitter.com/apps/new #How do I run the tests? Create two files: `config1.js` and `config2.js` at the root of the `twit` folder. They should contain two different sets of oauth credentials for twit to use (two accounts are needed for testing interactions). They should both look something like this: ``` module.exports = { consumer_key: '...' , consumer_secret: '...' , access_token: '...' , access_token_secret: '...' } ``` Then run the tests: ``` npm test ``` You can also run the example: ``` node examples/rtd2.js ``` ![iRTD2](http://dl.dropbox.com/u/32773572/RTD2_logo.png) The example is a twitter bot named [RTD2](https://twitter.com/#!/iRTD2) written using `twit`. RTD2 tweets about **github** and curates its social graph. ------- [FAQ](https://github.com/ttezel/twit/wiki/FAQ) ------- ## License (The MIT License) Copyright (c) by Tolga Tezel Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
