Quick Overview
Angular-socket-io is a library that provides a wrapper for Socket.IO in AngularJS applications. It simplifies the process of integrating real-time communication features into Angular projects by offering a service that manages Socket.IO connections and events within the Angular framework.
Pros
- Seamless integration with AngularJS, allowing for easy use of Socket.IO within Angular services and controllers
- Automatic event cleanup when Angular scopes are destroyed, preventing memory leaks
- Provides a convenient way to mock Socket.IO for testing purposes
- Simplifies the management of multiple socket connections
Cons
- Limited to AngularJS (version 1.x), not compatible with modern Angular versions (2+)
- Lacks built-in support for newer Socket.IO features and versions
- May require additional configuration for complex use cases
- Not actively maintained, with the last update being several years ago
Code Examples
- Initializing the socket service:
angular.module('myApp', [
'btford.socket-io'
]).
factory('mySocket', function (socketFactory) {
return socketFactory();
});
- Listening for events:
angular.module('myApp').controller('MyCtrl', function (mySocket) {
mySocket.on('connect', function () {
console.log('Connected to server');
});
mySocket.on('message', function (data) {
console.log('Received message:', data);
});
});
- Emitting events:
angular.module('myApp').controller('MyCtrl', function (mySocket) {
$scope.sendMessage = function (message) {
mySocket.emit('send:message', { message: message });
};
});
Getting Started
-
Install the library using npm:
npm install angular-socket-io
-
Include the script in your HTML file:
<script src="node_modules/angular-socket-io/socket.js"></script>
-
Add the module as a dependency in your Angular app:
angular.module('myApp', ['btford.socket-io']);
-
Create a socket factory in your app:
angular.module('myApp').factory('mySocket', function (socketFactory) { return socketFactory(); });
-
Inject and use the socket service in your controllers or services:
angular.module('myApp').controller('MyCtrl', function (mySocket) { mySocket.on('event', function (data) { console.log('Received event:', data); }); });

console.log(socket.id);
});
angular-socket-io:
angular.module('myApp', ['btford.socket-io'])
.factory('mySocket', function (socketFactory) {
return socketFactory();
});
// In a controller
mySocket.on('connect', function() {
console.log('Connected');
});
Summary
socket.io-client is a more robust and versatile library, offering broader functionality and better maintenance. However, angular-socket-io provides a more Angular-friendly approach with easier integration for Angular projects.

The API and real-time application framework
Pros of Feathers
- More comprehensive framework for building real-time applications and APIs
- Supports multiple databases and ORMs out of the box
- Provides a modular architecture with plugins and hooks for extensibility
Cons of Feathers
- Steeper learning curve due to its more extensive feature set
- May be overkill for simple socket.io implementations
- Requires more setup and configuration compared to angular-socket-io
Code Comparison
angular-socket-io:
angular.module('myApp', [
'btford.socket-io'
]).
factory('mySocket', function (socketFactory) {
return socketFactory();
});
Feathers:
const feathers = require('@feathersjs/feathers');
const socketio = require('@feathersjs/socketio');
const app = feathers();
app.configure(socketio());
Summary
Feathers is a more robust and feature-rich framework for building real-time applications, offering support for multiple databases and a modular architecture. However, it comes with a steeper learning curve and may be excessive for simple socket.io implementations. angular-socket-io, on the other hand, is more straightforward and easier to integrate into existing Angular applications but lacks the extensive features and flexibility of Feathers. The choice between the two depends on the project's complexity and requirements.
Socket.IO integration for Flask applications.
Pros of Flask-SocketIO
- Built specifically for Flask, providing seamless integration with Flask applications
- Supports multiple message queues (Redis, RabbitMQ, etc.) for scalability
- Offers extensive documentation and examples for various use cases
Cons of Flask-SocketIO
- Limited to Python backend, whereas Angular-Socket-IO is JavaScript-based
- May have a steeper learning curve for developers not familiar with Flask
Code Comparison
Flask-SocketIO:
from flask import Flask
from flask_socketio import SocketIO, emit
app = Flask(__name__)
socketio = SocketIO(app)
@socketio.on('message')
def handle_message(message):
emit('response', {'data': 'Received: ' + message})
Angular-Socket-IO:
angular.module('myApp', [
'btford.socket-io'
]).
factory('mySocket', function (socketFactory) {
return socketFactory();
});
Flask-SocketIO provides a more Python-centric approach, integrating directly with Flask applications. It offers built-in event handling and emitting capabilities. Angular-Socket-IO, on the other hand, focuses on creating a factory for Socket.IO in Angular applications, providing a more frontend-oriented solution.
Both libraries aim to simplify real-time communication in web applications, but they cater to different parts of the stack. Flask-SocketIO is ideal for developers working with Flask backends, while Angular-Socket-IO is better suited for Angular frontend developers looking to integrate Socket.IO functionality.

angular-socket-io
Bower Component for using AngularJS with Socket.IO, based on this.
Install
bower install angular-socket-io
or download the zip.- Make sure the Socket.IO client lib is loaded. It's often served at
/socket.io/socket.io.js
. - Include the
socket.js
script provided by this component into your app. - Add
btford.socket-io
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', [
'btford.socket-io',
'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', [
'btford.socket-io',
'myApp.MyCtrl'
]).
factory('mySocket', function (socketFactory) {
return socketFactory();
}).
controller('MyCtrl', function (mySocket) {
// ...
});
API
For the most part, this component works exactly like you would expect.
The only API addition is socket.forward
, which makes it easier to add/remove listeners in a way that works with AngularJS's scope.
socket.on
/ socket.addListener
Takes an event name and callback. Works just like the method of the same name from Socket.IO.
socket.removeListener
Takes an event name and callback. Works just like the method of the same name from Socket.IO.
socket.removeAllListeners
Takes an event name. Works just like the method of the same name from Socket.IO.
socket.emit
Sends a message to the server. Optionally takes a callback.
Works just like the method of the same name from Socket.IO.
socket.forward
socket.forward
allows you to forward the events received by Socket.IO's socket to AngularJS's event system.
You can then listen to the event with $scope.$on
.
By default, socket-forwarded events are namespaced with socket:
.
The first argument is a string or array of strings listing the event names to be forwarded.
The second argument is optional, and is the scope on which the events are to be broadcast.
If an argument is not provided, it defaults to $rootScope
.
As a reminder, broadcasted events are propagated down to descendant scopes.
Examples
An easy way to make socket error events available across your app:
// in the top-level module of the app
angular.module('myApp', [
'btford.socket-io',
'myApp.MyCtrl'
]).
factory('mySocket', function (socketFactory) {
var mySocket = socketFactory();
mySocket.forward('error');
return mySocket;
});
// in one of your controllers
angular.module('myApp.MyCtrl', []).
controller('MyCtrl', function ($scope) {
$scope.$on('socket:error', function (ev, data) {
});
});
Avoid duplicating event handlers when a user navigates back and forth between routes:
angular.module('myMod', ['btford.socket-io']).
controller('MyCtrl', function ($scope, socket) {
socket.forward('someEvent', $scope);
$scope.$on('socket:someEvent', function (ev, data) {
$scope.theData = data;
});
});
socketFactory({ ioSocket: }}
This option allows you to provide the socket
service with a Socket.IO socket
object to be used internally.
This is useful if you want to connect on a different path, or need to hold a reference to the Socket.IO socket
object for use elsewhere.
angular.module('myApp', [
'btford.socket-io'
]).
factory('mySocket', function (socketFactory) {
var myIoSocket = io.connect('/some/path');
mySocket = socketFactory({
ioSocket: myIoSocket
});
return mySocket;
});
socketFactory({ scope: })
This option allows you to set the scope on which $broadcast
is forwarded to when using the forward
method.
It defaults to $rootScope
.
socketFactory({ prefix: })
The default prefix is socket:
.
Example
To remove the prefix:
angular.module('myApp', [
'btford.socket-io'
]).
config(function (socketFactoryProvider) {
socketFactoryProvider.prefix('');
});
Migrating from 0.2 to 0.3
angular-socket-io
version 0.3
changes X to make fewer assumptions
about the lifecycle of the socket. Previously, the assumption was that your
application has a single socket created at config time. While this holds
for most apps I've seen, there's no reason you shouldn't be able to
lazily create sockets, or have multiple connections.
In 0.2
, angular-socket-io
exposed a socket
service. In 0.3
, it
instead exposes a socketFactory
service which returns socket instances.
Thus, getting the old API is as simple as making your own socket
service
with socketFactory
. The examples below demonstrate how to do this.
Simple Example
In most cases, adding the following to your app should suffice:
// ...
factory('socket', function (socketFactory) {
return socketFactory();
});
// ...
Example with Configuration
Before:
angular.module('myApp', [
'btford.socket-io'
]).
config(function (socketFactoryProvider) {
socketFactoryProvider.prefix('foo~');
socketFactoryProvider.ioSocket(io.connect('/some/path'));
}).
controller('MyCtrl', function (socket) {
socket.on('foo~bar', function () {
$scope.bar = true;
});
});
After:
angular.module('myApp', [
'btford.socket-io'
]).
factory('socket', function (socketFactory) {
return socketFactory({
prefix: 'foo~',
ioSocket: io.connect('/some/path')
});
}).
controller('MyCtrl', function (socket) {
socket.on('foo~bar', function () {
$scope.bar = true;
});
});
