In the modern web development landscape, the MERN stack—comprising MongoDB, Express.js, React.js, and Node.js—has emerged as a powerhouse. Today, we’re diving deep into a simple, yet effective example of user registration, login, and CRUD actions built using this stellar combination. This blog will guide you through creating a seamless authentication system with a sparkling front end powered by Material-UI!

What You Will Learn

This project encompasses the following key functionalities:

• Backend APIs for user registration and login
• CRUD functionality for users to manage products including adding, editing, and deleting them
• Pagination support for product listing
• JWT token authentication for secure access
• PDF printing option for product details

Prerequisites

Before you embark on this coding journey, ensure you have the following installed on your system:

• Node.js
• NPM (Node Package Manager)
• MongoDB

Setting Up the Project

To get started, follow these steps:

1. Clone or download the repository:

git clone https://github.com/FSojitra/Registration-Login-and-CRUD-Action-using-MERN-stack.git

2. Navigate to the backend directory:

cd Registration-and-Login-using-MERN-stack/backend

3. Install the necessary dependencies:

npm install

4. Now, navigate to the frontend directory:

cd ../frontend

5. And install the frontend dependencies:

npm install

Running the Application

Once the installation is complete, let’s run the application:

1. To run the Node server, navigate to the backend directory and use the following command:

node server.js

2. For the React frontend, in another terminal instance, navigate to the frontend directory and start the app:

npm start

Understanding the Code with an Analogy

Think of your application like a restaurant:

• The backend (Node.js and MongoDB) is like the kitchen where all the food (data) is prepared, stored, and served. The chef (Express.js) manages all incoming orders (requests) and decides what gets cooked (responded) based on the customer orders (API calls).
• The frontend (React.js with Material-UI) is like the dining area, where customers (users) interact with menus (UI components) to place their orders (CRUD actions). When they send a request (place an order), the waitstaff (Axios) takes these requests to the kitchen (backend), and the prepared dishes come back as responses (data provided back to the UI).

Troubleshooting Tips

If you encounter any issues during the setup or running of the application, consider the following troubleshooting ideas:

• Ensure that Node.js and MongoDB services are running.
• Check if the correct port is being used for the backend server.
• Make sure all necessary packages have been installed correctly without errors.
• Clear the browser cache if you encounter issues with the frontend not reflecting changes.
