Chromium's Base64 algorithm 🚀

Welcome to the chromium-base64 module - where encoding meets lightning speed! ⚡

Overview 📖

chromium-base64 is a supercharged JavaScript module for Base64 encoding and decoding. It's like base64-js but on steroids! 💪 With performance gains of nearly +80% (almost double the speed 🏎️), it's the new heavyweight champion in the encoding arena!

The Magic Behind 🧙‍♂️

Our hero, Matias Affolter 🦸‍♂️, delved deep into the Base64 algorithm and discovered the secret sauce used in Chromium's implementation by Nick Galbreath. This module is a testament to their combined genius, featuring low-level JavaScript (LLJS) close to asm.js style. It's like C and JS had a baby that's super efficient! 🍼

Installation 📦

npm install chrominium-base64

Usage 🛠

Importing and using chromium-base64 is a walk in the park:

var { B64chromium } = require('chromium-base64');
// `/dist/browser.min.js` --> var base64 = new window.B64chromium();

var base64 = new B64chromium();
var prefixpng = "data:image/png;base64,";
var base64str = "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"; // Made with pixa.pics

Forward Thinking 🌐

Embracing Chromium's Legacy

chromium-base64 isn't just about speed; it's about innovation and pushing boundaries. We draw inspiration from the finest in the field - Google Chrome. 🌟

Google Chrome, renowned for its efficiency, uses a decoder that's a work of art in its own right. Developed by Nick Galbreath, this "high-performance base64 encoder/decoder" is a cornerstone of Chromium's codebase. 🛠️

The Secret Sauce: Pre-Shifted 32-bit Values

What sets Chromium's implementation apart, and what we've embraced in chromium-base64, is its unique approach to decoding. Traditional base64 decoders rely heavily on shifts, but Chromium's decoder plays it smart. It bypasses shifts entirely, opting instead for a method where bytes are looked up as "pre-shifted" 32-bit values. 🧠💡

This approach isn't just about being different; it's about being better. It results in a decoder that's not only fast but also more efficient and reliable.

For the curious minds who want to dive deeper into this marvel, check out the detailed implementation at Lemire's fastbase64. 📚

Looking Ahead

In chromium-base64, we don't just code for today; we code for tomorrow. We're always on the lookout for ways to innovate and improve, keeping pace with the ever-evolving tech landscape. 🚀

Join us in this journey of exploration and excellence. With chromium-base64, the future of encoding is here and now! 🌌
