This question has some helpful info: How to do Base64 encoding in node.js?

The Buffer class itself does the conversion:

var base64data = Buffer.from('some binary data', 'binary').toString('base64');

console.log(base64data);
// ->  'c29tZSBiaW5hcnkgZGF0YQ=='

var originaldata = Buffer.from(base64data, 'base64');

console.log(originaldata);
// ->  

console.log(originaldata.toString());
// ->  some binary data
