How do i include multiple libraries on my local node.js server html page

So i have a html page with some facial recognition libraries on it and it works fine. But when i put the html page on a node.js local server, all the pictures and javascript libraries are not included anymore. For every library include i get an: "Uncaught SyntaxError: Unexpected token <" error, on the first line of the html page.

I tried to include them from within the node.js file like this:

var app = require('http').createServer(handler)
  , io = require('socket.io').listen(app)
  , fs = require('fs') 
  , five = require("johnny-five"),
  led;


//iets met poort 80
app.listen(80);

// webserver handler 
function handler (req, res) {

  fs.readFile(__dirname + '/emotie.html',
  function (err, data) {
    if (err) {
      res.writeHead(500);
      return res.end('Error loading index.html');
    }

    res.writeHead(200);
    res.end(data);
  });
}

function handler (req, res) {

  fs.readFile(__dirname + '/js/emotionmodel.js',
  function (err, data) {
    if (err) {
      res.writeHead(500);
      return res.end('Error loading emotionmodel.js');
    }

    res.writeHead(200);
    res.end(data);
  });
}

function handler (req, res) {

  fs.readFile(__dirname + '/js/emotion_classifier.js',
  function (err, data) {
    if (err) {
      res.writeHead(500);
      return res.end('Error loading emotionClassifier.js');
    }

    res.writeHead(200);
    res.end(data);
  });
} 

But it still doesnt work, and the filepath is right for sure.
