Introduction

This project is inspirated by squaremo.

Project goal is to provide a easy way to use rabbitMQ:

  • publish/subscribe: pub sockets publish to a rendezvous point; all sub sockets connected to the rendezvous point receive the messages.
  • publish/subscribe durable: pub sockets publish to a rendezvous point; all sub sockets connected to the rendezvous point receive the messages with an own queue.
  • task/work: task sockets publish to a rendezvous point; all work sockets connected to the rendezvous point receive the messages with an same queue.

Installation

$ npm install rabbitmq-nodejs-client

Pub/Sub usage

var rabbitHub = require('rabbitmq-nodejs-client');

var subHub = rabbitHub.create( { task: 'sub', channel: 'myChannel' } );
subHub.on('connection', function(hub) {

    hub.on('message', function(msg) {
        console.log(msg);
    }.bind(this));

});
subHub.connect();

var pubHub = rabbitHub.create( { task: 'pub', channel: 'myChannel' } );
pubHub.on('connection', function(hub) {

    hub.send('Hello World!');

});
pubHub.connect();

Task/Worker usage

var rabbitHub = require('rabbitmq-nodejs-client');

var taskHub = rabbitHub.create( { task: 'task', channel: 'myChannel' } );
taskHub.on('connection', function(hub) {

  var i = 0;
  setInterval(function() {
    hub.send('Hello World! ' + i);
    i++;
  }, 1000);

});
taskHub.connect();

//multiple instances of workers
var rabbitHub = require('rabbitmq-nodejs-client');

var workerHub = rabbitHub.create( { task: 'worker', channel: 'myChannel' } );
workerHub.on('connection', function(hub) {

  hub.on('message', function(msg) {
    console.log(msg);

    setTimeout(function() {
      hub.ack();
    }, 2000);
  }.bind(this));

});
workerHub.connect();
