Welcome to the world of MERN stack development! In this article, we will create a simple CRUD (Create, Read, Update, Delete) application using the MERN stack. This initiative is perfect for beginners who want to dive into web development. Let’s break it down step-by-step, creating both the backend and frontend using powerful technologies!

Technologies We Will Use

• React & React Router for the frontend
• Express & Mongoose for the backend
• Node.js (version 10+)

Requirements

To start building your MERN stack CRUD application, you’ll need to satisfy the following requirements:

• Install Node.js (10+ version) on your machine.
• Use npm install to install dependencies.

Setting Up Your Project

Now, let’s set up the backend and frontend of our application!

Backend Setup

First, navigate to your backend directory in the terminal and run the following command:

npm start

This command will start your server and make it ready to handle incoming requests.

Frontend Setup

Next, go to your frontend directory. You can run:

cd client

Now that you’re in the client directory, start your React application by running:

npm start

Your frontend should now be live and ready to interact with the backend!

Understanding the Code: An Analogy

Think of your MERN stack application as a restaurant. The React frontend is the menu and dining area where customers (users) place orders (input data). The Express backend acts like the kitchen that prepares the meals (handles requests). Finally, Mongoose is akin to the ingredients manager, ensuring that the right ingredients (data) are available for the kitchen to create delicious dishes (deliver the required output). In this setup, each customer can create new orders, check existing ones, update them or delete their previous choices seamlessly!

Troubleshooting Guide

If you encounter any issues while setting up or running your application, consider the following tips:

• Ensure that you have the correct version of Node.js installed.
• Double-check that all dependencies have been installed successfully using npm install.
• Verify that your server is running by checking for any terminal errors after you run npm start.
• If you face issues with routing in React, ensure that you’ve set up React Router correctly.
