A simple chat application written in AngularJS - using SockJS (not using server-side socket library such as Socket.io).
-- For a complete overview of the project and features, see http://selmanh.github.io/angularjs-chat/
Currently, I am working on my Master's degree final project (Chrome Application - soon to be published on Chrome Store, you can find the source code here: link) and one of my assignments was to develop a multi-player word guessing game.
While I was looking for options to create a multi-player game with chat support in AngularJS, I realized that, in so many projects, NodeJS was serving the AngularJS application using ExpressJS as a web application framework, and it was using server-side socket libraries such as Socket.IO.
After carefully considering a few other alternatives, I decided to use SockJS which doesn't force to serve AngularJS files from the server. After playing around with it, I thought it might be useful for others to have a working application that use both AngularJS and SockJS and decided to create this application.
I created a NodeJS server for this project. SockJS has implementations for other langugages as well, see https://github.com/sockjs.

AngularJS, sockjs-client

NodeJS, express, sockjs-client-node
Taken from its readme:
SockJS is a browser JavaScript library that provides a WebSocket-like object. SockJS gives you a coherent, cross-browser, Javascript API which creates a low latency, full duplex, cross-domain communication channel between the browser and the web server.
Under the hood SockJS tries to use native WebSockets first. If that fails it can use a variety of browser-specific transport protocols and presents them through WebSocket-like abstractions.
For more details about the SockJS project, see https://github.com/sockjs/sockjs-client.
I am sure you can break the live server (http://angularjs-chat-server.aws.af.cm/), but please, just try not to do that :) This is a simple project to show you how to use AngularJS and SockJS to create interactive applications.
I tested the application using 2 browsers on the same computer. Sometimes when you quit chat on one browser, the connection on the other browser gets broken. Feel free to fix the issue :)
-
First you need to install node_modules. Cd to node-server folder.
$cd node-server -
Execute
$sudo npm install -
Then, you need to install dependencies for our Angular application. Cd to angular-app folder.
$cd angular-app -
Execute
$sudo npm install -
And execute
$sudo bower install
-
Change directory to node-server folder
$cd node-server -
Start the Node server:
$node app -
Open another console and cd to angular-app folder
$cd angular-app -
Now, you can start the grunt server:
$grunt serve -
It will open the AngularJS app in your default browser. Have fun :)
