Felix Geisendorfer's Blog:
Include only the JS you really need
November 20, 2006 @ 07:46:00

In his latest entry, Felix shares a quick tip for CakePHP users out there to help them reduce the sizes of their pages and speed things up a little bit by including only the Javascript that you really need as a method inside your controller.

The basic idea is the addition of two functions and a variable to set the jsIncludes value and an includeJs/excludeJs pair to do the actual loading. The result is a much cleaner call to includeJs when rendering the application that will automatically pull in the files specified.

So if up to now you've always included all JS for every page load, this might help to reduce bandwidth usage for both you, and the users of your application. I know this is not the most advanced solution one could come up with. [...] But then I decided that it's too simple a problem for that kind of bloat.

All of the code is included here.
