murmurhash3

Node.js binding of MurmurHash3 C++ implementaion.

NPM

Build Status

Installation

$ npm install murmurhash3

or

$ git clone https://github.com/hideo55/node-murmurhash3.git
$ npm install ./node-murmurhash3

Usage

var mmh3 = require('murmurhash3');

mmh3.murmur32('key', function(err, hashValue){
  if (err) throw err;
  ...
});
mmh3.murmur128Hex('key', function(err, hashValue){
  if (err) throw err;
  ...
});

Functions

Async interfaces

murmur32(key [,seed], callback);    // return 32bit integer value
murmur32Hex(key [,seed], callback); // return 32bit hexadecimal string
murmur128(key [,seed], callback);   // return array that have 4 elements of 32bit integer
murmur128Hex(key [,seed], callback);// return 128bit hexadecimal string
  • seed is optional argument. (unsigned integer)
  • The callback gets two arguments (error, hashValue).

Sync interfaces

murmur32Sync(key [,seed]);    // return 32bit integer value
murmur32HexSync(key, [,seed]); // return 32bit hexadecimal string
murmur128Sync(key [,seed]);   // return array that have 4 elements of 32bit integer
murmur128HexSync(key [,seed]);// return 128bit hexadecimal string
  • seed is optional argument. (unsigned integer)

Requirement

  • Node v0.8, v0.10 and v0.12
  • io.js v1.0, v2.0, v3.0
