@urlpack/base-codec

Pure JavaScript implementation of the Base-N codec.
(1~255, it isn't compat with the Base16, Base32 and Base64)

• Zero dependencies
• ES Modules & Browser compatible
• Tree-shakable encoder and decoder

Usage

import { makeBaseEncoder, makeBaseDecoder } from '@urlpack/base-codec';

// Flickr-flavored Base58 characters
const alphabet = '123456789abcdefghijkmnopqrstuvwxyzABCDEFGHJKLMNPQRSTUVWXYZ'

const encoder = makeBaseEncoder(alphabet);
encoder.encode(binary); // Uint8Array => string

const decoder = makeBaseDecoder(alphabet);
decoder.encode(str); // => string => Uint8Array

It should be better. PR welcome
