cannot get / in a simple node file

I am trying to do a simple node / angular example of a book got. However i get an error when loading the page: cannot GET /

Anyone knows what i am doing wrong? Thanks

var express = require('express');
var bodyParser = require('body-parser');
var app = express();
app.use('/', express.static('./static')).
    use('/images', express.static( '../images')).
    use('/lib', express.static( '../lib'));
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());
var days=['Monday', 'Tuesday', 'Wednesday',
          'Thursday', 'Friday'];
var serviceDays = days.slice(0);
app.get('/reset/days', function(req, res){
  serviceDays = days.slice(0);
  res.json(serviceDays);
});
app.post('/remove/day', function(req, res){
  if (serviceDays.length > 2){
    serviceDays.splice(serviceDays.indexOf(req.body.day), 1);
    console.log(days);
    res.json(serviceDays);
  }else {
    res.json(400, {msg:'You must leave 2 days'});
  }
});
app.listen(8081);

I don't see you doing a .get() for this path /, which is the same as localhost:8081. Try doing something like this in your code.

app.get('/', function(req, res){
  serviceDays = days.slice(0);
  res.json(serviceDays);
});

This is the same as what you have here 

app.get('/reset/days', function(req, res){
  serviceDays = days.slice(0);
  res.json(serviceDays);
});

So if you go to localhost:8081 or localhost:8081/reset/days, you should get the same result. What the message cannot GET / is saying is that there is no route set up for the requested url.

Also note: It looks like you are using app.use('/', express.static('./static')) in your code. But it looks like this is just defining all of your static routes for "static", "images", and "lib".

Here is some more info on .use vs .get
