google/zopfli is a compression library to perform gzip, deflate or zlib compression.
# for npm users:npm install "@gfx/zopfli"# for yarnpkg usersyarnpkg add "@gfx/zopfli"
Note that the
gzip method is compatible with node-zopfli.
ZopfliOptions and its default is:
- NodeJS v8.0 or later
- GNU make
As of emscripten 1.37.28 + NodeJS 9.4.0 + macOS 10.12.6, the result is as follows:
## payload size: 1 universal-zopfli x 94.09 ops/sec ±5.51% (71 runs sampled) node-zopfli x 196 ops/sec ±4.22% (81 runs sampled) Fastest is node-zopfli ## payload size: 1024 universal-zopfli x 1.68 ops/sec ±1.35% (13 runs sampled) node-zopfli x 5.15 ops/sec ±0.69% (29 runs sampled) Fastest is node-zopfli ## payload size: 1038336 universal-zopfli x 0.29 ops/sec ±2.75% (6 runs sampled) node-zopfli x 0.39 ops/sec ±2.34% (6 runs sampled) Fastest is node-zopfli
That is, the performance of universal-zopfli is about 70% of native binding node-zopfli with 1MB payload.
