isomorphic-xxhash

Isomorphic wrapper for xxhash-wasm (browser) and xxhashjs (node). When bundling with tools like Webpack or Rollup (with browser hint enabled), only the WASM implementation should be included. A 13.2 kB browser build is included as an example, though if you want to include this library as a static <script>, plain xxhash-wasm offers a slightly smaller UMD build as well as an ES module.

Usage

NodeJS

import XXH from "isomorphic-xxhash";
// const XXH = require("isomorphic-xxhash");

const xxhash = await XXH();

xxhash.h32(/* may provide a seed (number) */)
    .update("text")
    .update(new Uint8Array([ 32, 58, 68 ]))
    .digest(); // number (781456070)

xxhash.h64(/* may provide a seed (bigint) */)
    .update("more text")
    .update(new Uint8Array([ 32, 240, 159, 152, 179 ]))
    .digest(); // bigint (5612704373666880606n)

Browser

<script src="https://unpkg.com/isomorphic-xxhash/browser/isomorphic-xxhash.min.js"></script>

The global XXH will be available.
