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
