RabbitMQ and Sails.js

I'm having trouble using RabbitMQ with my Sails app. I'm unsure of where to place the subscriber code. What I'm trying to do is build a notifications system so that when an administrator approves a user's data request, the user's dashboard will pop a notification similar to how Facebook pops a notification. The problem is, putting the subscriber code in my dashboard controller's display route seems to never grab a published message.

Any advice would be greatly appreciated. Currently using rabbit.js package to connect to RabbitMQ.

Here's an npm package that implements a RabbitMQ adapter for SailsJS.

To answer the original question, if one for some reason wanted to use Rabbit MQ instead of Sails' built-in resourceful pubsub, the best thing would be to use rabbit.js.

First, npm install rabbit.js.

Then, in your Sails project's config/sockets.js (borrowed liberally from the rabbit.js socket.io example):

var context = require('rabbit.js').createContext();
module.exports = {

     onConnect: function(session, socket) {
        var pub = context.socket('PUB');
        var sub = context.socket('SUB');

        socket.on('disconnect', function() {
          pub.close();
          sub.close();
        });

        // NB we have to adapt between the APIs
        sub.setEncoding('utf8');
        socket.on('message', function(msg) {
          pub.write(msg, 'utf8');
        });
        sub.on('data', function(msg) {
          socket.send(msg);
        });
        sub.connect('chat');
        pub.connect('chat');

    }

}
