Do you know how to create a MERN Stack? Do you know what a MERN Stack is? Do you know when you will need a MERN Stack?

1. Setting up the Backend

Here, we’re going to create the server-side of our application, where we’re going to create a RESTful following the steps.

2. Setting up the Frontend

Here we’re going to create all the visual parts, where the user will interact with our tool.

3. Conclusion

And that’s it, friend. In this article, you have seen the structure to build a MERN application using diverse libraries provided by an amazing community around the world.

What is the MERN Stack?

The MERN stack is a web development framework made up of the stack of MongoDB, Express.js, React.js, and Nodejs. It is one of the several variants of the MEAN stack.

Connecting to MongoDB Atlas

It’s time to connect our server to the database. We will use MongoDB Atlas as the database. MongoDB Atlas is a cloud-based database service that provides robust data security and reliability. MongoDB Atlas provides a free tier cluster that never expires and lets you access a subset of Atlas features and functionality.

Server API Endpoints

Database done. Server done. Now it's time for the Server API endpoint. Let's start by creating a routes folder and adding record.js in it. Navigate back to your “server” directory and create the new directory and file:

Setting Up the React Application

As we have already set up our React application using the create-react-app command, we can navigate to the client folder and check our React application code.

Setting Up the React Router

Let's start by emptying the src folder and adding two new files in it: index.js and App.js.

Creating Components

After adding the code to index.js files, we will create a components folder inside src. For each component we create, we will add a new .js file inside the components folder. In this case, we will add create.js, edit.js, navbar.js, and recordList.js.

Connecting the Front End to the Back End

We have completed creating components. We also connected our React app to the back end using fetch. fetch provides cleaner and easier ways to handle http requests. fetch is used in create.js, edit.js, and recordList.js as they handle http requests. In create.js, we appended the following code to the onSubmit (e) block.

Server setup with Express.js and Node.js

To begin our MERN stack tutorial, we’ll show you how to set up a server with Express.js and Node.js.

Database management with MongoDB

Now it’s time to work on our MERN database setup with MongoDB. For simplicity, we will use MongoDB Atlas.

Building RESTful APIs with the MERN stack

Create a folder named routes. In it, create another folder named api, which will hold all our APIs.

Building the frontend

So far, so good! Now that we’ve set up our backend, it’s time to transition to the frontend part of this MERN stack tutorial.

Setting up Create React App

Set any directory using a terminal where you want to keep all the files of this project and run the following command to get the initial setup file:

Initial project structure

Inside the project directory, our initial file structure should look like this:

Connecting the frontend to the backend

We just implemented all of our components! Now we need a little change in our server-side (back-end) project.
