Installation
npm i lz4-napi
# OR
yarn add lz4-napi
Usage
Compress
const { readFile } = require('fs/promises');
const { compress } = require('lz4-napi');
// if you support top-level await
const buffer = await readFile("./bigFile.dat");
const compressedBuffer = await compress(buffer)
// Store compressed buffer somewhere
Uncompress
const { uncompress } = require('lz4-napi');
// if you support top-level await
const compressedBuffer = await getFromSomeStorage();
const uncompressedBuffer = await uncompress(compressedBuffer)
// Do something with compressedBuffer!
