How do I read a file in Node.js without using callback?

Question

I am trying to read a file in node.js but I am getting tired of writing so many callbacks. Is there a way I can just read a file in one line?

If you're just loading a config or a template you can use the sync read method

var my fileData = fs.readFileSync('myFileName');

If you need you do it as a reply to an http request you can use the streaming API

function (req, res) {
  fs.createReadStream('myFileName').pipe(res);
}

Callbacks are king, but you can use anonymous callbacks...

fs.readFile('/etc/passwd', function (err, data) {
    if (err) throw err;
    console.log(data);
});
