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!

APIs

Promise

compress

(data: Buffer | string | ArrayBuffer | Uint8Array, dict?: string | Buffer) => Promise<Buffer>

uncompress

(data: Buffer | string | ArrayBuffer | Uint8Array, dict?: string | Buffer) => Promise<Buffer>

compressFrame

(data: Buffer | string | ArrayBuffer | Uint8Array) => Promise<Buffer>

decompressFrame

(data: Buffer | string | ArrayBuffer | Uint8Array) => Promise<Buffer>

Sync

compressSync

(data: Buffer | string | ArrayBuffer | Uint8Array, dict?: string | Buffer) => Buffer

uncompressSync

(data: Buffer | string | ArrayBuffer | Uint8Array, dict?: string | Buffer) => Buffer
