Encoding and Decoding images in base64 with Node

Take a trump.jpg and launch this gist.

var fs = require('fs');

function base64_encode(file) {
    console.time('encoding')
    var bitmap = fs.readFileSync(file);
    var result =  new Buffer(bitmap).toString('base64');
    console.timeEnd('encoding')
    return result;
}

function base64_decode(base64str, file) {
    console.time('decoding')
    var bitmap = new Buffer(base64str, 'base64');
    fs.writeFileSync(file, bitmap);
    console.timeEnd('decoding')
}

var base64str = base64_encode('trump.jpeg');
console.log(base64str)
base64_decode(base64str, 'copy.jpg');
