Unleash the power of XMPP in order to build exciting, real-time, federated applications based on open standards in a secure and highly scalable fashion
About This Book
- Learn about the fundamentals of XMPP and be able to work with the core functionality both server-side and in the browser
- Build a simple 1-to-1 chat (the “Hello World” of XMPP), explore multi-user chat, publish subscribe systems, and work with a decentralized social network
- Author Lloyd Watkins is a member of the XMPP standards committee
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 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).
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”
In Detail
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.
Style and approach
Through a number of hands-on projects, this book shows you how to build usable applications that highlights a feature of XMPP.
Lloyd Watkin Lloyd Watkin has over 10 years of experience in building for the Web. A great believer in open source and open standards, he has contributed to, started, and led many successful open source projects and is also an international conference speaker. Lloyd was knowingly introduced to XMPP in 2012 and hasn't looked back. Its open standard base and the ability to code clients, servers, components in any language leads to a very diverse and healthy environment. Its relevance only seems to increase as new technologies (not imagined at the time of creation) come into existence.
David Koelle David Koelle is a principal software engineer at Charles River Analytics Inc. in Cambridge, Massachusetts, USA, where he has employed XMPP on projects to facilitate collaboration and shared situational awareness among distant teams. He is also the author of JFugue, a popular open source music programming API for Java and other JVM languages, and he is a co-organizer for the Boston Android Meetup. David has delivered several award-winning talks at high-profile conferences including JavaOne and SXSW. In addition to his technical work in software engineering and systems engineering, he finds opportunities to mentor engineers to help them grow in their careers and recognize the value that proactive leadership can bring to engineers and their environments. David is a graduate of Worcester Polytechnic Institute (WPI).
