pako

zlib port to javascript. Very fast!

Why pako is cool:

• Almost as fast im modern browsers as C implementation (see benchmarks)
• Works in browser
• Modular - you can browserify any separate component
• Both Sync & streamable interfaces (streamable is for big blobs)
• It's fresh - ports the latest zlib version (now 1.2.8)
• Tested - result is binary equal to zlib's one
• No restrictions - MIT licence

Benchmarks:

node v0.11, 10mb sample:

   deflate-gildas x 2.82 ops/sec ±1.21% (11 runs sampled)
   deflate-imaya x 2.25 ops/sec ±0.59% (9 runs sampled)
 ! deflate-pako x 6.09 ops/sec ±0.98% (19 runs sampled)
   deflate-zlib x 9.13 ops/sec ±0.92% (46 runs sampled)

node v0.11, 10mb sample:

   deflate-gildas x 3.39 ops/sec ±6.58% (12 runs sampled)
   deflate-imaya x 2.14 ops/sec ±4.29% (9 runs sampled)
 ! deflate-pako x 6.61 ops/sec ±0.66% (20 runs sampled)
   deflate-zlib x 9.28 ops/sec ±1.98% (47 runs sampled)

API

TBD

Notes

Since pako was done mostly for browser, some specific functions were left unported.

deflate:

• writing custom gzip headers (default is ok)
• deflateSetDictionary, deflateParams, deflateSetHeader, deflateBound, deflatePending

inflate:

TBD

We will probably provide more modular design, to keep significant part of code reasonably small.
