Twitter stream apiThe communication layer is built upon Twitter’s infrastructure

var twit = new twitter(config);

// Check Credentialstwit.verifyCredentials(function (err, data) { if(err) console.log(err);}).stream('user', {track:watch}, function(stream) {

console.log("Twitter stream is ready and waiting for inc tweets...")

stream.on('data', function (data) {

//Check if tweet is not emptyif (data.text !== undefined) {

//Action Code here}

});

//Catch errorsstream.on('error', function (err, code) {

console.log("err: "+err+" "+code)});
