In this course, you’ll learn how to build a full-stack application using the MERN stack and deploy it to the internet. The MERN stack is a popular stack of technologies that build modern Single Page Applications (SPAs).

You’ll begin with the basics of MongoDB and the process of setting it up. Next, you will go over work with the Atlas cloud database. Then, you’ll learn how to set up the backend using Node and express. Also, you’ll be creating a fully functional movie review application. After creating the controller and data access objects, you’ll learn to create routes. Next, you’ll test the created API. Finally, you’ll learn how to create the frontend using the React components and deploy the application on Heroku.

By the end of this course, you’ll learn how to connect both the backend and the frontend to create a full-stack MERN application, as well as how to deploy it.
