string-hash

What is string-hash?

The string-hash npm package is designed to generate integer hash values from string inputs. It's a simple and efficient way to create hash codes, which can be useful for various applications such as hashing keys for objects or arrays, generating unique identifiers, and more. The package provides a straightforward API for hashing strings.

What are string-hash's main functionalities?

Generating hash from a string

This feature allows you to generate a hash code from a given string. The code sample demonstrates how to import the string-hash package, use it to hash the string 'Hello World', and then log the hash code to the console.

"const stringHash = require('string-hash');\nconst myHash = stringHash('Hello World');\nconsole.log(myHash);"

Other packages similar to string-hash

xxhashjs

xxhashjs is a pure JavaScript implementation of the xxHash algorithm. It offers fast hashing and supports both 32-bit and 64-bit hash values. Compared to string-hash, xxhashjs provides more options in terms of hash size and might be preferred for applications requiring non-integer hash values or higher collision resistance.

hasha

hasha is a Node.js library for hashing strings, Buffers, and streams. It supports multiple hash algorithms, including MD5, SHA-1, and SHA-256. Unlike string-hash, which generates integer hash codes, hasha can produce hex, base64, or Buffer outputs and offers more flexibility in terms of hashing algorithms.

string-hash

A fast string hashing function for Node.JS. The particular algorithm is quite similar to djb2, by Dan Bernstein and available here. Differences include iterating over the string backwards (as that is faster in JavaScript) and using the XOR operator instead of the addition operator (as described at that page and because it obviates the need for modular arithmetic in JavaScript).

The hashing function returns a number between 0 and 4294967295 (inclusive).

Thanks to cscott for reminding us how integers work in JavaScript.
