To test your Socket.io implementation, build a simple chat application. Your chat will be constructed from several server event handlers, but most of the implementation will take place in your Angular application. We'll begin with setting the server event handlers.
Before implementing the chat client in your Angular application, you'll first need to create a few server event handlers. You already have a proper application structure, so you won't implement the event handlers directly in your configuration file. Instead, it would be better to implement your chat logic by creating a new file named chat.server.controller.js inside your app/controllers folder. In your new file, paste the following lines of code:
module.exports = function(io, socket) {
io.emit('chatMessage', {
type: 'status',
text: 'connected',
created: Date.now(),
username: socket.request.user.username
