Ratchet isn’t built specifically for Laravel 4, so there are no service providers for us to add.
We’ll now have access to the Ratchet library for client-server communication, Bootstrap for styling
the interface and EmberJS for connecting these two things together.
ReactPHP
Before we can understand Ratchet, we need to understand ReactPHP. ReactPHP was born out of
the need to develop event-based, asynchronous PHP applications. If you’ve worked with Node.JS
you’ll feel right at home developing applications with ReactPHP; as they share a similar approaches
to code. We’re not going to develop our chat application in ReactPHP, but it’s a dependency for
Ratchet…

One of the many ways in which real-time client-server applications are made possible is by what’s
called socket programming. Believe it or not; most of what you do on the internet depends on socket
programming. From simple browsing to streaming — your computer opens a socket connection to a
server and the server sends data back through it.
