How to listen to socket emit on sails.io.js?

Question

I'm using Sails 0.11 in my back-end, and angularjs in the front-end.

I have a TwitterController in sails with the following code, to open a stream with the Twitter Streaming API (this uses the node module twit):

var Twit = require('twit');

var T = new Twit(sails.config.twit);

var stream = T.stream('statuses/filter', {
    track: ['apple']
});

module.exports = {
    open: function(req, res) {
        if (!req.isSocket) {
            return res.badRequest();
        }

        var socketId = sails.sockets.id(req.socket);

        stream.start();

        stream.on('tweet', function(tweet) {
            sails.log.debug('Tweet received.');
            sails.sockets.emit(socketId, 'tweet', tweet);
        });
    }
};

In my front-end (with the angular-sails module):

$sails.get('/twitter/open').then(function(resp) {
  console.log(resp.status);
}, function(resp) {
  alert('Houston, we got a problem!');
});

This of course reaches my back-end controller, and the streaming starts, but how do I listen to the

sails.sockets.emit(socketId, 'tweet', tweet);

issued by the server?.

I'd appreciate any help here!.

Answer 1

Following wZVanG's answer. This is how I did it, using the angular-sails angular module.

$sails.get('/twitter/open').then(function(resp) {
  console.log(resp.status);
}, function(resp) {
  alert('Houston, we got a problem!');
});

$sails.on('tweet', function(message) {
  console.log(message);
});

That logs every tweet received to the browser's console.

Sails library creates a global variable "io", so you can use also:

io.socket.on("tweet", function(data){})
