An extremely simple implementation of base64 encoding / decoding using node.js Buffers

base64.js

//
// Super simple base64 encoding / decoding with node.js
//

var base64 = exports = {
  encode: function (unencoded) {
    return new Buffer(unencoded).toString('base64');
  },
  decode: function (encoded) {
    return new Buffer(encoded, 'base64').toString('utf8');
  }
};

This is very, very handy. Thank you.

The Buffer constructor is deprecated according to the documentation.
It can lead to vulnerability that can result from using it in the ws library.
Instead, use something like this:

return Buffer.from("Hello World").toString('base64');
and
return Buffer.from("SGVsbG8gV29ybGQ=", 'base64').toString('utf8');

@budiony — thanks, saved me a lot of nerves =)
