#twit

Twitter API Client for node

Supports both the REST and Streaming API.

#Installing

npm install twit

##Usage:

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, reply) {
  //  ...
})
      
//
//  search twitter for all tweets containing the word 'banana' since Nov. 11, 2011
//
T.get('search/tweets', { q: 'banana since:2011-11-11' }, function(err, reply) {
  //  ...
})

//
//  get the list of user id's that follow @tolga_tezel
//
T.get('followers/ids', { screen_name: 'tolga_tezel' },  function (err, reply) {
  //  ...    
})

//
//  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)
})

twit API:

Just 3 methods. They cover the full twitter API.

##T.get(path, [params], callback)
GET any of the REST API Endpoints.

##T.post(path, [params], callback)
POST any of the REST API Endpoints.

##T.stream(path, [params])
Use this with the Streaming API.

Note: Omit the .json from path (i.e. use 'statuses/sample' instead of 'statuses/sample.json').

###params

Params is an optional object, allowing you to pass in parameters to Twitter when making a request. Any Arrays passed into params get converted to comma-separated strings, allowing you to do requests like:

//
// 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.

###path

• If path is 'user', the User stream of the authenticated user will be streamed.
• If path is 'site', the Site stream of the authenticated application will be streamed.
• If path is anything other than 'user' or 'site', the Public stream will be streamed.

The following events are emitted:

##event: 'tweet'

Emitted each time a status (tweet) comes into the stream.

stream.on('tweet', function (tweet) {
  //...
})

##event: 'delete'

Emitted each time a status (tweet) deletion message comes into the stream.

stream.on('delete', function (deleteMessage) {
  //...
})

##event: 'limit'

Emitted each time a limitation message comes into the stream.

stream.on('limit', function (limitMessage) {
  //...
})

##event: 'scrub_geo'

Emitted each time a location deletion message comes into the stream.

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.

stream.on('disconnect', function (disconnectMessage) {
  //...
})

##event: 'connect'

Emitted when a connection attempt is made to Twitter. The http request object is emitted.

stream.on('connect', function (request) {
  //...
})

##event: 'reconnect'

Emitted when a reconnection attempt is made to Twitter. The http request and response objects are emitted, along with the time (in milliseconds) left before the reconnect occurs. Twit follows Twitter's guidelines on reconnecting to the Streaming API.

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.

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.

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.

stream.on('user_withheld', function (withheldMsg) {
  //...
})

##event: 'friends'

Emitted when Twitter sends the "friends" preamble when connecting to a user stream. This message contains a list of the user's friends, represented as an array of user ids.

stream.on('friends', function (friendsMsg) {
  //...
})

##event: 'user_event'

Emitted when Twitter sends back a User stream event.
See the Twitter docs for more information on each event's structure.

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:

stream.on('favorite', function (event) {
  //...
})

##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 a config.js at the root of the twit folder. It should export the oauth credentials. It should 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

The example is a twitter bot named RTD2 written using twit. RTD2 tweets about github and curates its social graph.
