Evented Twitter is an asynchronous twitter client for node.js. I supports the REST api and the Streaming API (no search yet).

Usage

REST

var util = require('util');

var Twitter = require('evented-twitter').Twitter;
var t = new Twitter('username', 'password');
t.userTimeline('json', null, function(result) {
     // The response is not parsed for you
     try {
         json = JSON.parse(result);
     } catch(e) {}

     util.puts(util.inspect(json));
});

util.puts('Calling ' + t.lastAPICall);

You can inspect the Twitter function to see what methods are available

util.puts(util.inspect(Twitter));

Streaming

var util = require('util');

var TwitterStream = require('evented-twitter').TwitterStream;
var t = new TwitterStream('username', 'password');

var params = {'track':'Twitter'};

// statuses/sample from streaming api
var stream = t.filter('json', params);

// There are also functions for filter, links, retweet and firehose.
// Fill out the params object with query params to them
// i.e. params = {delimeter: 'length', track: 'Twitter'}

// see the api call that is being made
util.debug('Calling ' + t.lastAPICall);

// "ready" is emitted when the stream is ready to go
// Similar to how clientRequest emits "response"
// Now you can attach events
stream.addListener('ready', function() {
    stream.addListener('tweet', function(tweet) {
        if(!String(tweet).trim()) return;
        try {
            // The result is not parsed for you
            var t = JSON.parse(tweet);
            util.puts(util.inspect(t));
        } catch(e) {
            util.debug('\nProblem parsing: ' + tweet);
            util.debug(e.message);
            util.debug(e.stack);
        }
    });

    stream.addListener('complete', function(response) {
        stream.close();
    });
});

stream.addListener('error', function(err) {
    util.debug(err.message);
    throw err;
});

stream.start();
