Book Description
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.
What you will learn
Install and configure an XMPP server and use it to connect from a traditional desktop client and send a message
Build a simple server-side application that will respond to messages from our logged in desktop client
Install and run XMPP-FTW, connect to the server from the browser, and handle incoming/outgoing messages
Connect to a multi-user chat room, send/receive stanzas, add a room password, join a protected room, set the room's subject, and change a user's affiliation
Get to grips with the publish-subscribe extension of XMPP and use it to build a pusher system that can make any website real-time
Build a simple XMPP component and create an extension for XMPP-FTW that allows you to use your own custom format
Build an XMPP version of the classic game “Pong”
Who this book is for
If you want to learn about the fundamentals of XMPP, be able to work with the core functionality both server-side and in the browser then this book is for you. No knowledge of XMPP is required, or of TCP/IP networking. It’s important that you already know how to build applications of some form, and are looking to get a better understanding of how to implement XMPP for one or more of its many uses. You should be interested in the decentralized web, know HTML, and likely know JavaScript and NodeJS. You will probably know JSON, and hopefully XML (this is the native output of XMPP).
