Node: How to read file?

I want to read a file and return is as a response to GET request

This is what I am doing

app.get('/', function (request, response) {
    fs.readFileSync('./index.html', 'utf8', function (err, data) {
        if (err) {
            return 'some issue on reading file';
        }
        var buffer = new Buffer(data, 'utf8');
        console.log(buffer.toString());
        response.send(buffer.toString());
    });
});

index.html is

hello world!

When I load page localhost:5000, the page spins and nothing happens, what is I am doing incorrect here

I am newbie to Node.

You're using the synchronous version of the readFile method. If that's what you intended, don't pass it a callback. It returns a string (if you pass an encoding):

app.get('/', function (request, response) {
    response.send(fs.readFileSync('./index.html', 'utf8'));
});

Alternatively (and generally more appropriately) you can use the asynchronous method (and get rid of the encoding, since you appear to be expecting a Buffer):

app.get('/', function (request, response) {
    fs.readFile('./index.html', { encoding: 'utf8' }, function (err, data) {
        // In here, `data` is a string containing the contents of the file
    });
});
