How to perform X-FACEBOOK-PLATFORM and Google Talk X-OAUTH2 XMPP authentication with PHP Jaxl library

Ever since Jaxl library first introduced support for X-FACEBOOK-PLATFORM XMPP authentication mechanism, it has changed significantly. Also, Google Talk now supports OAuth 2.0 Authorization, an XMPP extension to allow users to log in using OAuth 2.0 credentials. Both these mechanisms are a big win for XMPP developers, since real-time conversation experience can now be provided to their application users without asking them for their passwords. In this blog post, I will demonstrate how to perform X-FACEBOOK-PLATFORM and X-OAUTH2 XMPP authentication mechanism using Jaxl v3.x PHP Library.

JAXLXml – Strophe style XML Builder : Working with Jaxl – A Networking Library in PHP – Part 2

Prior to Jaxl v3.x, the most ugliest piece of code inside Jaxl library was handling of XML packets. If you are working with XMPP protocol which is all about sending and receiving XML packets, it can become a nightmare if you don’t have a proper XML manipulation library in your toolkit. For Jaxl v3.x, first thing I decided to write was JAXLXml class, which is a custom XML packet implementation with no external dependencies and is an extension over the ideas from Strophe.Builder class written by Jack Moffitt. JAXLXml is generic enough to find a place inside any PHP application that requires easy and elegant XML packet creation. In this blog post, I will give an exhaustive overview of how to create XML packets using JAXLXml class.

Working with Jaxl – A Networking Library in PHP – Part 1 – An Introduction, Philosophy and History

Development of Jaxl library started way back in December’07 while I was working on a self-initiated project called Gtalkbots. The project is now dead, if you are interested in knowing more about it go through Gtalkbots BlogSpot. Jaxl v1.x was first released in Jan’09 and about a year later in Aug’10 Jaxl v2.x was released. First two versions were released as JAbber XMPP Library for writing clients and external server components.

Announcing Jaxl v3.x – asynchronous, non-blocking I/O, event based PHP client/server library

Jaxl v3.x is a successor of v2.x (and is NOT backward compatible), carrying a lot of code from v2.x while throwing away the ugly parts. A lot of components have been re-written keeping in mind the feedback from the developer community over the last 4 years. Also Jaxl shares a few philosophies from my experience with erlang and python languages. Jaxl is an asynchronous, non-blocking I/O, event based PHP library for writing custom TCP/IP client and server implementations. From it’s previous versions, library inherits a full blown stable support for XMPP protocol stack. In v3.0, support for HTTP protocol stack was also added.

PHP Code, Setup and Demo of Jaxl boshchat application

Jaxl 2.0 bosh support allow web developers to write real time web applications within minutes, without having any pre-requisite knowledge about the XMPP protocol itself. In this blog post, I will walk you through setup and demo of an XMPP based web chat application using Jaxl library.
