Client side data compress/decompress?

compression, gzip, javascript

Solution

There is this open-source Javascript compression library, by Pierre curto : https://github.com/pierrec/node-lz4

Googling around, I also found this zlib implementation (not tested by me) : http://nodejs.org/api/zlib.html

Problem

I'm looking for a JavaScript implementation of a string compress/decompress algorithm where data is created at the client side and stored in hidden fields within HTML forms. I read about gzip, but it compresses the data server side whereas in my case I want to compress it client side, send it to the server, or receive it from server to decompress it again at client side. I found this LZF Compression example based on LZFjs but it will generate binary data which needs to be processed and stored in a hidden form field, and it works on files rather than pure data. Suggestions on a pure data client-side data compression/decompression that is also efficient?
