murmurhash-js

MurmurHash.js

An optimized JavaScript implementation of the MurmurHash algorithms.

These algorithms take a JavaScript string (and a seed), and quickly create a non-cryptographic 32-bit hash from it. And by quick I mean sub-millisecond performance.

More information about these algorithms can be found at:

• MurmurHash Homepage
• Wikipedia Entry on MurmurHash

Install

npm install murmurhash-js

API

var murmur = require("murmurhash-js")

Methods

murmur.murmur2(key, seed)

Runs the murmur2 hash algorithm on the string key with initial seed seed.

murmur.murmur3(key, seed)

Runs the murmur3 hash algorithm on the string key with initial seed seed.

Note require("murmur-hash") is the same as murmur.murmur3
