ts-base32

Base32 encode and decode in typescript exported as both commonjs and tree shakeable modules. Support for RFC4648, RFC4648_HEX, and CROCKFORD base32 encoding. Mostly directly taken from LinusU's packages.

Demo: https://ts-base32.ep.workers.dev

Install

npm install @ctrl/ts-base32

Use

import { base32Encode, base32Decode } from '@ctrl/ts-base32';
import { stringToUint8Array, uint8ArrayToString } from 'uint8array-extras';

console.log(base32Encode(stringToUint8Array('a')));
// 'ME======'

console.log(base32Encode(stringToUint8Array('a'), { padding: false }));
// 'ME'

console.log(base32Decode('ME======'));
// Uint8Array

console.log(uint8ArrayToString(base32Decode('ME======'))
// 'a'

Benchmarks

64KB payload, Node.js, ops/s (higher is better): @exodus/bytes uses nodejs Buffer, but is very fast.
