But as top 2 position link for key world “js compressor” in Google, I decide not to disappoint visitors with no discrete implementations any more. Here now, I give an implementation (Thanks for J2S 1.0.0 M3, so such a solution does not require much time and pains):
This LZ77 implementation was considered as buggy. I used in J2S Clazz.
BTW: Developing the above J2S/SWT application (including wrapping the old LZ77 utilities into a servlet) took me about 2 hours.
For JS compressor, I recommend you to use Dean’s Packer.
