What is object-hash?

The object-hash npm package provides a function to generate a hash from a JavaScript object using various algorithms. It is useful for creating unique identifiers for objects, comparing objects by their hash, and caching objects based on their content.

What are object-hash's main functionalities?

Generate hash from an object

This feature allows you to generate a hash string from a JavaScript object. The hash is determined by the object's content.

const hash = require('object-hash');
const myObject = { name: 'Alice', age: 25 };
const objectHash = hash(myObject);

Generate hash with different algorithms

This feature allows you to specify different hashing algorithms, such as 'md5', 'sha1', 'sha256', etc., to generate the hash.

const hash = require('object-hash');
const options = { algorithm: 'sha256' };
const objectHash = hash({ name: 'Alice', age: 25 }, options);

Exclude properties from hashing

This feature allows you to exclude the values of the properties from the hash, effectively hashing the structure (keys) of the object only.

const hash = require('object-hash');
const options = { excludeValues: true };
const objectHash = hash({ name: 'Alice', age: 25 }, options);

Respect object types

This feature allows you to ignore the type of the object when generating the hash, treating arrays and objects with the same content as equal.

const hash = require('object-hash');
const options = { respectType: false };
const objectHash = hash([1, 2, 3], options);
