Deploying the Node Application to Heroku

1. Create Procfile and add ‘web: nodemon app.js’.
2. Create new db in mlab.
3. Create new user for that db in mlab.

    MONGO_URI=mongodb://localhost/<dbname>
   

5. Create .env.production and add:

   mongodb://<dbuser>:<dbpassword>@<address>:<port>/<dbname>
   

6. In app.js, check to see if these have been added, if not add:

   dotenv.load({ path: '.env.' + process.env.NODE_ENV});
   mongoose.connect(process.env.MONGO_URI);  
   app.listen(process.env.PORT || <your port>);
   

7. In terminal, run: heroku create
