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.

React is a library released by Facebook that creates user interfaces with components. For example, if we want to build a storefront module like what we see on Amazon, we can divide it into three parts—the **Search Bar**, **Side Bar**, and **Product** components, as shown below:


Components can also contain other components. For example, in the Product component where a list of products is displayed, we use multiple other product components. Also, in each Product component, we can have a **Rating** component. The benefit of architecture like this is that it helps us break up an extensive application into manageable components. Moreover, we can reuse components within (or even in a different) application.

A React component contains a JSX template that ultimately outputs HTML elements. It has its own data and logic to control the JSX template. When the values of its data change, React updates the concerned UI component. An example of a component that displays a simple string `Products` is given below:
