ErlyComet allows to plug in Bayeux compliant Comet functionality in Erlang Web servers. ErlyComet ships with a sample server implementation for running the demos.

Features:

• Web server support:
• MochiWeb HTTP toolkit
• Javascript libraries:
• dojo
• http://jquery.com with jquery Comet plugin (from SVN)
• Transport types:
• long-polling
• callback-polling
• optional Bayeux features:
• JSON comment filtered format (to prevent Ajax Hijacking)
• Channel globbing
• Service channels
• Easy pluggable custom applications (decoupled from Comet logic)
• Designed as distributed system from ground up
• Connection and channel management with distributed in-memory database

Demos:

• Simple echo
• Server side counter
• RPC (with custom serverside application)
• Simple chat
• Collaborative drawing

ToDo:

• create a dojo custom build for the demos
• handle Multi frame operations (Bayeux spec section 8) to overcome the two connection limit
• make ErlyComet run also on Crary web server
• add authentication, load balancing
• replace homegrown cluster management with fragmentron
• add more transport types: Flash (RTMP), iframe, ActiveX (as in gmail for IE), etc.
• integrate with http://erlware.org
• load testing

Project status:

For using this software in production you should wait until the ToDo items have shifted up to the Features list !
