Base92+64 JavaScript Encoder and Decoder

GREAT = Base92, GOOD = Base64;

Probably THE ONLY PURE-JS BASE92 (2023) encoding/decoding system in javascript, most notably also faster than half of the st*pid base64 encoding/decoding library (it re-use the memory system and is written in low-level javascript in order to make the engine work based on lighter dataset and operations)

While Gzip (used in most web servers nowadays) is well suited for Base64, it doesn't lose any key (compression) performance based on Base92, but the greatest of "it all" is that, IT SHOULD ALWAYS HAVE BEEN BASE92 IN JSON AND SUCH BECAUSE IT CAN BE EASILY (The lazy situp-wordu of many companies are just operator not architect)

GREAT IS THE ENEMY OF GOOD

The Base92 JavaScript module provides methods to encode and decode data using a base92+64 encoding scheme. It is not faster than base64 but it provides a more space-efficient result in UTF-8 or UTF-16 source code strings, making it useful for all kinds of inline data in source code.

The module is minified and has a footprint of just 14 kB, and requires no dependencies. This makes it an easy and lightweight solution for your encoding needs.

Installation

Since this module is provided as an npm package, you can install it using npm:

npm install base92

Usage

Import the module into your JavaScript code:

var BaseN = require('base92');
var Base92 = BaseN.Base92;
var Base64 = BaseN.Base64;

Import the minified file into your JavaScript code:

 // <script> 'index.min.js';
var Base92 = window.Base92;

Encoding

To encode data, create an instance of the Base92 class and use the encode method. This method takes a Uint8Array` as input:

var data = new Uint8Array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9]);
var base92 = new Base92();

// You have to tell if you want to have a new Uint8Array because... Wait!
// If you don't the system will reuse the memory system of the instanciated class' JS object, OK?!
// Optional, WILL trigger a copy (if set to true) of the internal (memory) storage system...
var slice = false; // This variable' parameter's (secondary) position is not mandatory
// Just to know, if you don't get a copy and do encoding operation twice, you might have the same Uint8Array twice

var encodedData92 = base92.encode(data, slice); // "  ,@%7 sBv&]1"
console.log(encodedData92);

Decoding

To decode data, use the decode method of the Base92` class instance. This method takes a string as input:

var decodedData92 = base92.decode(encodedData92);
console.log(decodedData92);
