Rails and Javascript minifier and aggregator

Question

I am starting a new rails project and is there any rails plug in I can use that will minify my javascript and combine it into 1 file?

I would imagine there might be a rake task for this.

What would be used for this in rails?

There are several actually:

I've only used asset packager, and its been nothing but a joy.

Jammit is a really nice all-in-one solution. If you want more flexibility, the GitHub strategy is an excellent starting point. – Simone Carletti Nov 25 '09 at 09:58

I've only used asset_packager as well, but it did everything so well that I didn't find a reason to look elsewhere. – wesgarrison Dec 30 '09 at 07:28

Rails has built in javascript file merging.

http://apidock.com/rails/ActionView/Helpers/AssetTagHelper/javascript_include_tag

javascript_include_tag :all, :cache => true

I then use nginx's built in gziping to compress the file size, since it does a pretty good job. There are numerous plugins to do it also:

You might also want want to checkout Juicer. It primarily combines files, but it can work with YUI Compressor and JSLint if you don't mind Java in your toolkit/dependency chain. It's also not specific to Rails, so you could "standardize" on it for all your projects--if you find you like it.

Just an idea.
