What is @types/object-hash?
@types/object-hash provides TypeScript type definitions for the object-hash library, which is used to create unique hashes for JavaScript objects. This is useful for tasks such as caching, object comparison, and ensuring data integrity.
What are @types/object-hash's main functionalities?
Basic Hashing
This feature allows you to generate a hash for a simple JavaScript object. The hash can be used to uniquely identify the object.
const objectHash = require('object-hash');
const hash = objectHash({ foo: 'bar' });
console.log(hash);
Hashing with Options
This feature allows you to customize the hashing algorithm and encoding. In this example, the SHA-1 algorithm and hex encoding are used.
const objectHash = require('object-hash');
const hash = objectHash({ foo: 'bar' }, { algorithm: 'sha1', encoding: 'hex' });
console.log(hash);
Hashing Arrays
This feature allows you to generate a hash for an array. The hash will uniquely represent the array's contents.
const objectHash = require('object-hash');
const hash = objectHash([1, 2, 3, 4]);
console.log(hash);
Hashing Nested Objects
This feature allows you to generate a hash for nested objects. The hash will uniquely represent the entire structure of the nested object.
const objectHash = require('object-hash');
const hash = objectHash({ foo: { bar: 'baz' } });
console.log(hash);
Other packages similar to @types/object-hash
hash-it
hash-it is a lightweight library for creating unique hashes for JavaScript objects. It is similar to object-hash but focuses on performance and simplicity.
crypto
The crypto module in Node.js provides cryptographic functionality that includes a set of wrappers for OpenSSL's hash, HMAC, cipher, decipher, sign, and verify functions. While it is more general-purpose, it can be used to hash objects with some additional work.
fast-json-stable-stringify
fast-json-stable-stringify is a library that provides deterministic JSON.stringify() results. It can be used in conjunction with a hashing function to create consistent hashes for objects.
