[jira] Commented: (TAPESTRY-2179) Javascript Adapter Architecture

    [ https://issues.apache.org/jira/browse/TAPESTRY-2179?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12581834#action_12581834 ] 

Francois Armand commented on TAPESTRY-2179:
-------------------------------------------

The Tapestry irc channel #tapestry on freenode brings the topic of cometd / bayeux protocols and implementation, which are push system for AJAX (the server signal update to the client, and so the client does not have to pop the server periodically). 

Reference :
- The Bayeux protocol : http://svn.xantus.org/shortbus/trunk/bayeux/bayeux.html
- Comet daemon (cometd) : http://cometd.com/
This is java implementation as a servlet (embedded with the Jetty project): http://svn.xantus.org/shortbus/trunk/cometd-java/README.TXT

> Almost every aspect in T5 can be easily overridden or decorated - except the client side javascript code.
> A lightweight javascript isolation layer would allow people to swap the javascript frameworks.
> http://extjs.com/ uses this approach (can be driven by own, prototype, jquery, etc..) and it works well.
> The isolation level layer should respect javascript programming patterns (module pattern, keep the DOM clean,..). This would allow T5 to smoothly integrate in existing (corporate) environments.
