@zig-wasm/hash

Fast non-cryptographic hash functions powered by Zig via WebAssembly.

Install

- pnpm add @zig-wasm/hash

Quick start

``ts
import { crc32Hex, wyhash, xxhash64 } from "@zig-wasm/hash";

const crc = await crc32Hex("payload");
const xxh = await xxhash64(new Uint8Array([1, 2, 3]));
const wy = await wyhash("payload"); // Uint8Array digest
`

Call await init() before using any *Sync helpers (crc32Sync, hashSync,
etc.).

Algorithms

- Checksums: crc32, adler32
- General-purpose: xxhash32/64, wyhash, fnv1a32/64, murmur2_64,
cityhash64
- Generic helpers: hash, hashHex, hash32, hash64 with HashAlgorithm
types

See src/index.ts for the full async and sync exports.

WASM loading options

- Async APIs lazy-load hash.wasm.
- Override with init({ wasmUrl | wasmPath | wasmBytes, imports }) when
self-hosting.
