fastlz

node-fastlz

This is the start of some bindings to FastLZ. FastLZ is an implementation of lz77 which may not get the best compression ratio, but is relatively CPU efficient.

status

This library is a work in progress. I'm releasing it as 1.0.0 because it is going into production. But it only supports synchronous compression at the moment. We'll be fleshing out the API as needed (decompression and async) but those will wait on us actually needing those capabilities.

These bindings have only been tested with Node.js 5.x and 6.x. If you need an older version of node, and that version is still supported by the node core team, patches are welcome to get it working.

usage

fastlz.compressSync(sourceBuffer, sourceDataLength) -> compressedBuffer

sourceBuffer is the data you want compressed. sourceDataLength is the length of the data starting at 0 in the sourceBuffer. compressedBuffer is a minimally sized buffer of the compressed data.

example

const fastlz = require('fastlz');

const dataToCompress = Buffer.from('this string is gunna be smaller!', 'utf8');
const compressedData = fastlz.compressSync(dataToCompress, dataToCompress.length);
