Encoding and decoding Base64 text, in Node.js, is as easy as:

function base64Encode(text) {
    return new Buffer(text).toString('base64');
}

function base64Decode(text) {
    return new Buffer(text, 'base64').toString('utf8');
}

This code is used by my new online Base64 decoder/encoder utility.
