I’m using just a few basic jQuery functions on my site.
How can I remove unused jQuery code?
Knowing only the basics, I looked at the code and was not sure where to start.
If you could point me in the right direction, that would be appreciated.
Thanks.
jQuery itself isn’t really built to be selectively used. There are lots of interdependencies between its own functions and the source isn’t laid out to be easy to modularise. Unlike the situation with plugins like jQuery-UI, the core of jQuery is pretty much take-it-or-leave-it.
If you’ve only used a few simple functions, you might be able to rewrite them in plain JavaScript. If the main function you’re using is selectors you can use Sizzle, which is the underlying selector library that jQuery itself uses. Otherwise… not really.
