database.js:

module.exports = {
    'url' : 'your-database-here' 

};

Answer 1

In your server.js should be this bit of code (assuming you are following the tutorial you linked exactly).

var configDB = require('./config/database.js');
mongoose.connect(configDB.url);

According to that code, your database.js file must be in a config folder (rather then in the same folder as server.js). So make sure you are doing that.

Next, place your mongodb url like so in your database.js.

module.exports = {
    'url' : 'mongodb://<user>:<pass>@mongo.onmodulus.net:27017/Mikha4ot'
};

Make sure to replace <user> with your username and <pass> with your password.
