Package Exports

lz4-wasm

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (lz4-wasm) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

`lz4-wasm`

Extremely fast compression(200MB/s) and decompression(600MB/s) in the browser or nodejs using wasm.

_{Built with Rust}

🚴 Usage

The wasm module exposes two function compress and decompress. Both accept and return UInt8Array. Internally the lz4 block api is used, the length of the original input is prepended in 32-bit little endian.


import * as wasm from "lz4-wasm";

// use TextEncoder to get bytes (UInt8Array) from string
var enc = new TextEncoder();
const compressed = wasm.compress(enc.encode("compress this text, compress this text pls. thx. thx. thx. thx. thx"));
const original = wasm.decompress(compressed);

var dec = new TextDecoder("utf-8");
alert(dec.decode(original))
