Ext Extensions

My Own

I have chosen to store all my extensions on http://github.com/scottp/

However, I have chosen to publish my extensions on http://extjs-ux.org/

Issues

Some issues I have we can improve with Ext.

Feedback on missing information

"root" is a required input to a Ext.tree.TreePanel - but if you don't add it, Ext throws an error deep in the Ext library - very hard to debug. Why can't Ext just tell us that it is missing or required?

One answer is that it would add a lot to the size, but we have the answer there by adding Debug entries. It could even be added as a separate library that extends the original classes with config checks - either by a hook, or overwriting initComponent or similar.

Perl Library

This project is currently a little stale...

See ExtJS Perl Library

My random notes on implementations with Perl.

AJAX - JSON or XML

So you want to get some data back dynamically. The choices are:

Status code of HTTP request
Presentation / Browser data such as HTML, an Image or similar
XML (pretty much any schema)
JSON

So which one?

CDN

(see also CDN)

There are two solutions currently for CDN 3rd party hosted cache of these files:

http://cachefile.net/scripts/ext/2.1/ - working now
http://code.google.com/apis/ajaxlibs/ - but it isn't there yet
