Pusher Twitter Streamer

A small tool that takes tweets from the Twitter stream and triggers Pusher events.

Prerequisites

• a Twitter application
• a free Pusher account

Usage

npm install --save pusher-twitter-streamer

var Streamer = require('pusher-twitter-streamer');
var streamer = new Streamer({
  twitter: {
    consumerKey: ...,
    consumerSecret: ...,
    accessTokenKey: ...,
    accessTokenSecret: ...
  },
  pusher: {
    appId: '123456',
    appKey: 'abc123',
    appSecret: 'def456',
    channelName: 'tweets',
    eventName: 'new_tweet'
  }
});
 
streamer.stream('javascript', 'ruby', 'python');

Filtering

Not all tweets that match the filter are sent to Pusher by default, we filter to only include English tweets. Additionally, we only push a subset of the tweet data to the client.

If you'd like to overrride this, you should redefine Streamer.prototype.publishFilter. This is expected to return undefined if you do not wish to use that tweet, or an object representing the tweet if you do.

Fake Stream

The Twitter streamer also has a file with ~3000 tweets that it can send to you at the rate of 1 a second, for those times when the internet is failing during your demo. To do this replace the call to streamer.stream with streamer.streamFake().
