lz4js-pure

• 📦 No dependencies - only 3.7kb
• 💍 Pure JS
• 🌳 Plug n play with kafkajs
• 🚀 Tuned for performance
• 💨 Much faster than kafka-lz4-lite

Optimal for json data, txt or small files. While this package is made with special attention to performance its recommended to use a performant C/Rust package if you are mainly doing large files.

General use

import { compress, decompress } from 'lz4js-pure';

const payload = Buffer.from(`It's a dangerous business, Frodo, going out your door. You step onto the road, and .....`);
const payload_lz4 = compress(payload);
const payload_dcomp = decompress(payload_lz4);

Use with kafkajs

import { CompressionTypes, CompressionCodecs } from "kafkajs";
import { codec } from 'lz4js-pure';

CompressionCodecs[CompressionTypes.LZ4] = codec;

Roadmap

• Keep up to date with nodejs releases and possible improvements
• Improve and document error handling
• Tests
• Benchmarks
