How to do Base64 encoding in node.js?

Question

Does node.js have built-in base64 encoding yet?

The reason why I ask this is that final() from crypto can only output hex, binary or ascii

Answer 1

I am using following code to decode base64 string in node API nodejs version 10.7.0

let data = 'c3RhY2thYnVzZS5jb20=';  // Base64 string
let buff = new Buffer(data, 'base64');  //Buffer
let text = buff.toString('ascii');  //this is the data type that you want your Base64 data to convert to
console.log('"' + data + '" converted from Base64 to ASCII is "' + text + '"'); 

Please don't try to run above code in console of the browser, won't work. Put the code in server side files of nodejs. I am using above line code in API development.
