I'm having serious issues with an app I am building with Node.js, Express, MongoDB and Mongoose. Last night everything seemed to work when I used nodemon server.js to `run the server. On the command line everything seems to be working but on the browser (in particular Chrome) I get the following error: No data received ERR_EMPTY_RESPONSE. I've tried other Node projects on my machine and they too are struggling to work. I did a npm update last night in order to update my modules because of another error I was getting from MongoDB/Mongoose { [Error: Cannot find module '../build/Release/bson'] code: 'MODULE_NOT_FOUND'}. I used the solution in this answer to try and fix it and it didn't work and I still get that error. Now I don't get any files at all being served to my browser. My code is below. Please help:

//grab express and Mongoose

var express = require('express');

var mongoose = require('mongoose');

var Schema = mongoose.Schema;



//create an express app

var app = express();



app.use(express.static('/public/css', {root: __dirname}));



//create a database

mongoose.connect('mongodb://localhost/__dirname');



//connect to the data store on the set up the database

var db = mongoose.connection;



//Create a model which connects to the schema and entries collection in the __dirname database

var Entry = mongoose.model(Entry, new Schema({date: 'date', link: 'string'}), entries);



mongoose.connection.on(open, function() {

    console.log(mongodb is connected!);

});



//start the server on the port 8080

app.listen(8080);



//The routes



//The route for getting data for the database

app.get(/database, function(req, res) {

    Entry.find({}, function(err, data) {console.log(err, data, data.length); });



});



//The route for posting data on the database

app.post(/database, function(req, res) {

    //test new post

    var newMonth = new Entry({date: '1997-10-30', link: 'https://wwww.youtube.com/'});

        newMonth.save(function(err) {

            if (err !== null) {

                //object was not save

                console.log(err);

                    } else {

                console.log(it was saved!)

        };

    });

});







//create an express route for the home page at http://localhost:8080/

app.get('/', function(req, res) {

    res.send('ok');

    res.sendFile('/views/index.html', {root: __dirname + ''});

});



//Send a message to the console

console.log('The server has started');
