I’ve inherited a high-traffic site that loads some Ext javascript files and I’m trying to trim some bandwidth usage.

Are Ext libraries necessary for development only or are they required for the finished site? I’ve never used Ext.: Ext JS – Client-side JavaScript Framework

The site loads ext-base.js (35K), ext-all-debug.js (950K), expander.js, exteditor.js. It appears that expander.js and exteditor.js have some site specific code, so they should stay?

But what about ext-base.js and ext-all-debug.js? Am I reading this correctly – are base and debugging libraries necessary for a live site?

    Simply consult the documentation the previous developers have written for you. 😛

    To actually answer your question: You will more than likely want to keep all of the files available. You might however want to change ext-all-debug.js to ext-all.js since the debug file contains non-minimized Javascript.
