b64-lite

Node, browser, and React Native base64 library

Usage

const b64 = require('b64-lite');
 
// Base64 in ASCII to byte string
b64.atob('aGkgdGhlcmU=');
// hi there
 
// byte string to Base64 in ASCII
b64.btoa('hi there');
// aGkgdGhlcmU=
 
// convert unicode to b64
b64.toBase64('hello 你好');
// aGVsbG8g5L2g5aW9
 
// convert a buffer to b64
b64.toBase64(new Uint8Array([228, 189, 160, 229, 165, 189]).buffer);
// 5L2g5aW9
 
// decode b64 to unicode
b64.fromBase64('aGVsbG8g5L2g5aW9');
// hello 你好
 
// convert b64 to a buffer
b64.toBuffer('5L2g5aW9');
// new Uint8Array([228, 189, 160, 229, 165, 189]).buffer

Can it be smaller?

If you use ES6 imports with a bundler that supports tree-shaking, yes!

import { toBase64 } from 'b64-lite'
