Package description
The btoa npm package is a utility for encoding data to base64, particularly designed to mimic the btoa function available in web browsers. It is primarily used to convert binary data to a base64 encoded string, which is useful for transmitting data over media that are designed to deal with textual data.
Base64 Encoding
This feature allows you to encode a string into a base64 format. The provided code sample demonstrates encoding the string 'Hello, World!' into its base64 representation.
const btoa = require('btoa');
const encodedData = btoa('Hello, World!');
console.log(encodedData);base64-js is a package that provides similar base64 encoding and decoding functionalities. Unlike btoa, which only offers encoding and is designed to mimic the browser's btoa function, base64-js also supports decoding from base64, making it more versatile for various use cases.
The buffer module available in Node.js can also handle base64 encoding and decoding. It is built into Node.js, so it doesn't require an additional npm installation. This makes it a convenient choice for Node.js applications, offering a broader range of functionalities compared to the btoa package.

A port of the browser's btoa function.
Uses Buffer to emulate the exact functionality of the browser's btoa
(except that it supports some unicode that the browser may not).
It turns binary data to base64-encoded ascii.
(function () {
"use strict";
var btoa = require('btoa');
var bin = "Hello, 世界";
var b64 = btoa(bin);
console.log(b64); // "SGVsbG8sIBZM"
}());
Note: Unicode may or may not be handled incorrectly. This module is intended to provide exact compatibility with the browser.
