Practical XMPP

By: Lloyd Watkin, Steven Watkin, Koelle

Overview of this book

XMPP (eXtensible Messaging and Presence Protocol) is a messaging protocol that enables communication between two or more devices via the Internet. With this book, developers will learn about the fundamentals of XMPP, be able to work with the core functionality both server-side and in the browser, as well as starting to explore several of the protocol extensions. You will not only have a solid grasp of XMPP and how it works, but will also be able to use the protocol to build real-world applications that utilize the power of XMPP. By the end of this book, you will know more about networking applications in general, and have a good understanding of how to extend XMPP, as well as using it in sample applications.

1. An Introduction to XMPP and Installing Our First Server

Running the server and clients


At this point, you have a functioning server-side component and functioning clients, so it's time to see them working together, sending messages back and forth, and letting you get a good game of Pong in before lunchtime. Ready?

Your server component may already be running. If not, restart the Prosody service using the following command:

sudo service prosody start

Run the component from the pong-component directory:

node index.js

For the clients, open a second terminal window, navigate to the directory with the client's index.js code and run that (node index.js), then open a browser and visit http://localhost:3000.

You may want to open a second browser, also point it to http://localhost:3000, and get your own one-on-one Pong game going.
