Can I compress data in JavaScript?

I'm using some pretty heavy AJAX with lots of data going from client to server. How can I compress the data (mostly plain text) before sendi开发者_如何学编程ng to the server?

And how can I uncompress the data on the server side?

jSEND seems to do EXACTLY this. Anyone ever use it?

The jsolait library has a codec that supports the LZW algorithm (among others, including base64 encoding/decoding). The only thing that makes me a little hesitant is that this library is no longer being actively maintained.

EDIT

I was able to find a few more implementations of the LZW algorithm in Javascript.
