approximate-hash

Super fast approximate hashing function for large, deeply nested objects and arrays, also with circular dependencies.
It does not use all of the objects but is just sampling them up to the given depth or length.

Installation

For node.js:

npm install approximate-hash

For bower:

bower install approximate-hash

Usage

var approximateHash = require('approximate-hash');

var obj = {
    ...large, deeply nested object or array
};

console.log(approximateHash(obj));

// c0d76cd9b4a1e343e284456ab4471825

API

var approximateHash = require('approximate-hash');

var options = {
    objectDepth: 7,
    arrayDepth: 7,
    stringDepth: 100
};

console.log(approximateHash(obj, options));

objectDepth - argument object will be analyzed up to the given depth

arrayDepth - maximal number of elements taken from each array

stringDepth - maximal number of characters taken from each string
