React Node.js MySQL CRUD Tutorial for Beginners

Introduction

In this tutorial, we will learn how to create a basic CRUD (Create, Read, Update, Delete) application using React, Node.js, and MySQL. This tutorial is targeted towards beginners who are new to these technologies.

Prerequisites

• A basic understanding of HTML, CSS, and JavaScript
• Node.js and npm installed on your machine
• MySQL database setup

Step 1: Setting up the Project

First, let’s create a new directory for our project. Open your terminal or command prompt and run the following command:

mkdir react-node-mysql-crud-tutorial

Once the directory is created, navigate into it:

cd react-node-mysql-crud-tutorial

Next, initialize a new Node.js project:

npm init

Follow the prompts and enter the required information. This will generate a package.json file for our project.

Step 2: Setting up the Backend

Now, let’s install the required dependencies for our backend. Run the following command:

npm install express mysql body-parser

This will install Express, MySQL, and Body-parser packages.

In your project directory, create a new file called server.js. Open it and import the necessary modules:

const express = require('express');
    const mysql = require('mysql');
    const bodyParser = require('body-parser');

Next, set up the connection to your MySQL database:

const db = mysql.createConnection({
        host: 'localhost',
        user: 'your_username',
        password: 'your_password',
        database: 'your_database_name'
    });
    
    db.connect((err) => {
        if (err) {
            throw err;
        }
        console.log('Connected to the MySQL database');
    });

Initialize Express and configure the server:

const app = express();
    const port = 3000;

Step 3: Setting up the Frontend

In your project directory, create another directory called client:

mkdir client

Navigate into the client directory:

cd client

Create a new React app:

npx create-react-app .

This will create a new React app inside the client directory.

Step 4: Creating the UI

Open the src/App.js file in the client directory and replace its contents with the following code:

import React from 'react';
    
    function App() {
        return (

        );
    }
    
    export default App;

Conclusion

In this tutorial, we have set up the basic structure for our React Node.js MySQL CRUD application. We have created the project directory, set up the backend with Express and MySQL, and created the frontend with React. In the next steps, we will implement the CRUD operations and connect the frontend with the backend to complete the application.

Stay tuned for the next part of this tutorial where we will continue building the application!
