atob in node code example
Example 1: nodejs atob
// If you need to convert to Base64 you could do so using Buffer:
console.log(Buffer.from('Hello World!').toString('base64'));
// Reverse (assuming the content you're decoding is a utf8 string):
console.log(Buffer.from(b64Encoded, 'base64').toString());
Example 2: atob nodejs

"use strict";
var atob = require('atob');
var b64 = "SGVsbG8sIFdvcmxkIQ==";
var bin = atob(b64);
