node-murmurhash

NOTE: This is a port of Gary Court's excellent work, to a commonJS module that can be easily included into a node.js project or the browser. I take no credit for the implementation. I am simply making it easier to use for others.

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:

Installation

Install it in your browser:

<script type="text/javascript" src="murmurhash.js"></script>

To support older browsers you need to use TextEncoder polyfill

or in node.js

npm install murmurhash
murmurhash = require('murmurhash')

Both version 2 and 3 of the MurmurHash algorithm are supported:

// generates a v2 hash
murmurhash.v2("some input", "some seed value (optional)")

// generates a v3 hash
murmurhash.v3("some input", "some seed value (optional)")
