SL Combinator Speed up your website by combining and compressing JavaScript or CSS files on-the-fly.

SL Combinator saves previously combined and compressed files for later use, and is smart enough to check for an up-to-date cache file before deciding to create a new one.

What’s the big deal?

Best practise dictates that we combine and compress JavaScript and CSS files wherever possible, to reduce HTTP requests and download times.

Unfortunately, minified JavaScript and CSS is no good when you’re actually writing and testing code, so you end up with multiple uncompressed files for development, and separate combined and compressed files for the live site.

Every time you update your code, you have to manually re-combine and re-compress the source files for use on the live site, making even the most trivial update a major annoyance.

Of course, you could just decide it’s not worth the hassle, and use the development files on the live site; but then your visitors suffer because of the increased page weight.

SL Combinator puts an end to this frustration, making it easy to have your cake and eat it too — multiple separate JavaScript and CSS files for easy editing and debugging, zero time wasted combining and compressing files for use on the live site, and no hefty downloads for your visitors.

This is really useful, thanks Stephen.
