JavaScript Base64 Encode

var string = "Hello folks how are you doing today?";
var encodedString = btoa(string); // Base64 encode the String
var decodedString = atob(encodedString); // Base64 decode the String

JS decodifica base64

let str = 'bmltZXNoZGV1amEuY29t';
let buff = new Buffer(str, 'base64');
let base64ToStringNew = buff.toString('utf8');

Base 64 em JS

// Define the string
var string = 'Hello World!';

// Encode the String
var encodedString = btoa(string);
console.log(encodedString); // Outputs: "SGVsbG8gV29ybGQh"

// Decode the String
var decodedString = atob(encodedString);
console.log(decodedString); // Outputs: "Hello World!"
