Full-Stack Web Development with Vue.js and Node

Going Live Chapter 10

The last thing we need to change is the port of the application. The Heroku application
automatically assigns a port when deploying an application. We should only be using

port 8081 of the development environment only. So, let's verify that our server.js has

the following code:

const port = process.env.PORT || 8081;

app.use('/', router);

var server = app.listen(port, function() {

console.log(`api running on port ${port}`);

});

module.exports = server

Now, let's commit and push the changes to the master and then deploy again:

$ git add package.json config/Config.js server.js

$ git commit 'Update MongoDB url and app port'

$ git push origin master

$ git push heroku master

The application should be successfully deployed to Heroku and we should be able to view

our application at https:/​/​movie-​rating-​app-​1.​herokuapp.​com/​:
