JavaScript DEFLATE Implementation [closed]

Answer 1

I found a DEFLATE encoder and decoder implementation at http://github.com/dankogai/js-deflate and they both work perfectly.

Answer 2

I believe Pako (https://github.com/nodeca/pako) is now the fastest javascript implementation of deflate and other zlib methods (inflate / gzip / ungzip). There are benchmarks on the github page. It also supports chunking if you need to work with big blobs.
