node-murmurhash-native

Uses native C++ code from https://github.com/aappleby/smhasher repository to bring MurmurHashes (versions 2 and 3) with correct big numbers to node

Version 2

32 bits

int murmurHash2(string|Buffer data, [int seed]) - the simple implementation

int murmurHash2A(string|Buffer data, [int seed]) - the simple implementation w/ Merkle-Damgard-esque construction

int murmurHashAligned2(string|Buffer data, [int seed]) - the little-endian aligned-read-only implementation

int murmurHashNeutral2(string|Buffer data, [int seed]) - the (slower) endian-neutral implementation

64 bits

string murmurHash64A(string|Buffer data, [int seed]) - 64-bit hash for 64-bit platforms, returns hex string

string murmurHash64B(string|Buffer data, [int seed]) - 64-bit hash for 32-bit platforms, returns hex string

Version 3

32 bits

int murmurHash3_x86_32(string|Buffer data, [int seed])

128 bits

string murmurHash3_x86_128(string|Buffer data, [int seed]) - 128-bit hash for 32-bit platforms, returns hex string

string murmurHash3_x64_128(string|Buffer data, [int seed]) - 128-bit hash for 64-bit platforms, returns hex string

Usage example

> var hasher = require("murmurhash-native")
> hasher.murmurHash3_x64_128("ws2yy")
'9410cb6cee7e741319a92e1b06482e33'
> hasher.murmurHash2("ws2yy")
2490241110

Installation from Git

git clone --recursive 'https://github.com/TheRoSS/node-murmurhash-native.git'
cd node-murmurhash-native
npm install

Note the --recursive option. It loads native MurmurHash repository with C++ modules

I found the more complete module for this task. It's better to use it instead of mine
