sindresorhus / string-hash

Get the hash of a string

string-hash

Get the hash of a string

Uses the non-cryptographic hash function FNV-1a.

Similar to Java's String#hashCode().

Install

npm install @sindresorhus/string-hash

Usage

import stringHash from '@sindresorhus/string-hash';

stringHash('🦄🌈');
//=> 2868248295

stringHash('👌😎');
//=> 2903279002

It returns the hash as a positive integer.

FAQ

Why is this just a small wrapper around the fnv1a package?

Answer.

string-hash's Issues

Support variable bit-width

I recently encountered a similar use case (went for crc16 btw) where the hash had to be provided as a 16-bit number. Given JS-numbers are 64 bits and FNV-1a allowing variable bit length up to 1k I could see this as a useful configurable parameter defaulting to 64.

Document relation to @sindresorhus/fnv1a

While looking for a package that generates FNV hashes, I came upon both @sindresorhus/string-hash and @sindresorhus/fnv1a. I got rather confused trying to find a relevant difference between them, so I fully read through both readme files, then finally the source code itself, where it turned out that this package is merely a one-line wrapper around the other one.

I'm not really sure what the rationale behind this is, but maybe you could add a short sentence to the readme files so that later visitors don't get confused in the same way I did.

Re-export?

Why is this module a re-export of @sindresorhus/fnv1a?

I would assume because of the understandable package name.
