@addmaple/lz4

Fast LZ4 compression in the browser and Node.js using Rust + WASM.

2.5x-3.5x faster than lz4js.

Installation

npm install @addmaple/lz4

Usage

import { init, compress } from '@addmaple/lz4';

await init();

const input = new TextEncoder().encode('hello world');
const compressed = await compress(input);

Inline (Zero-latency)

WASM bytes embedded directly in JS — no separate file fetching:

import { init, compress } from '@addmaple/lz4/inline';

await init();
const compressed = await compress(input);

API

init()

Initialize the WASM module.

compress(input)

• input: Uint8Array
• Returns: Promise<Uint8Array>

Note: LZ4 is a single-speed algorithm optimized for maximum throughput. Unlike Brotli/Gzip, it doesn't have compression levels.
