angular-sockjs

SockJS provider for AngularJS.

Based on Brian Ford's angular-socket-io.

Install

1. bower install angular-sockjs
2. Made sure the SockJS client library is loaded.
3. Include the socket.js script provided by this component into your app.
4. Add bd.sockjs as a module dependency to your app.

Usage

This module exposes a socketFactory, which is an API for instantiating sockets that are integrated with Angular's digest cycle.

Making a Socket Instance

// in the top-level module of the app
angular.module('myApp', [
  'bd.sockjs',
  'myApp.MyCtrl'
])
.factory('mySocket', function (socketFactory) {
  return socketFactory();
});

With that, you can inject your mySocket service into controllers and other serivices within your application!

Using Your Socket Instance

Building on the example above:

// in the top-level module of the app
angular.module('myApp', [
  'bd.sockjs',
  'myApp.MyCtrl'
])
.factory('mySocket', function (socketFactory) {
  return socketFactory({
    url: 'https://example.com'
  });
})
.controller('MyController', function (mySocket) {
  // ...
});

API

Since the SockJS API uses single event handlers rather than Socket.io's event emitter style, this library provides a lightweight wrapper around the handlers.

socket.setHandler(event, callback)

Accepts valid socket events: open, close, and message. Returns socket wrapper so multiple calls can be chained.

socket.removeHandler(event)

Handles the same events as socket.setHandler. Returns socket wrapper so multiple calls can be chained.

socket.send(message)

Sends a socket message.

socket.close([code], [reason])

Attempts to close the socket.

Options

socketFactory({socket: })

This option allows you to provide the socket service with a SockJS instance to be used internally. This is useful if you need to hold a reference to the sockjs object for use elsewhere.

angular.module('myApp', [
  'bd.sockjs'
])
.factory('mySocket', function (socketFactory) {
  var sockjs = new SockJS('http://host');

  mySocket = socketFactory({
    socket: sockjs
  });

  return mySocket;
});

socketFactory({url: })

This option allows you to provide a URL to pass through to the SockJS constructor.
