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:
- 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 !
