Can I compress data in JavaScript?

Question

I use rather heavy AJAX with a lot of data going from client to server. How to compress data (mostly plain text) before sending it to the server?

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

Answer 1

jSEND seems to do it EXACTLY. Has anyone ever used it?

Answer 2

The jsolait library has a codec that supports the LZW algorithm (among other things, including base64 encoding / decoding). The only thing that makes me hesitate a bit is that this library is no longer supported.

EDIT

I was able to find <a href = "" rel = "nofollow"> a slightly larger implementation of the LZW algorithm in Javascript.
