Building a Web Application with React and Node.js

In this tutorial, we’ll be building a simple web application using React on the front-end and Node.js on the back-end. We’ll start by setting up a basic file structure and then move on to creating the user interface using React. After that, we’ll build the back-end using Node.js and connect it to the front-end. By the end of this tutorial, you’ll have a fully functional web application that you can customize to fit your needs.

Setting up the Project

Before we get started, we need to set up our project. We’ll be using create-react-app to create our React application and express to create our Node.js server.

First, let’s create a new React app by running the following command:

1
2

npx create-react-app my-app
cd my-app

Next, let’s install express and cors by running the following command:

1

npm install express cors

Now that we have our dependencies installed, let’s create a new file called server.js in the root of our project directory. In this file, we’ll create our Node.js server and connect it to our React app. Here’s what our server.js file should look like:

const express = require('express');
const cors = require('cors');
const app = express();

app.use(cors());

app.listen(5000, () => {
  console.log('Server is running on port 5000');
});

Creating the User Interface with React

Now that our server is set up, let’s create the user interface using React. We’ll start by creating a few components: a header component, a form component, and a display component. Here’s what our App.js file should look like:

import React from 'react';
import Header from './components/Header';
import Form from './components/Form';
import Display from './components/Display';

function App() {
  return (
    <div>
      <Header />
      <Form />
      <Display />
    </div>
  );
}

export default App;

Next, let’s create our form component. We’ll use a table to lay out our form and some Bootstrap classes to style it. Here’s what our Form.js file should look like:

import React from 'react';

function Form() {
  return (
    <form>
      <table>
        <tbody>
          <tr>
            <td>
              <label htmlFor="name">Name:</label>
            </td>
            <td>
              <input type="text" id="name" name="name" />
            </td>
          </tr>
          <tr>
            <td>
              <label htmlFor="email">Email:</label>
            </td>
            <td>
              <input type="email" id="email" name="email" />
            </td>
          </tr>
          <tr>
            <td>
              <label htmlFor="password">Password:</label>
            </td>
            <td>
              <input type="password" id="password" name="password" />
            </td>
          </tr>
          <tr>
            <td colSpan="2">
              <button type="submit">Submit</button>
            </td>
          </tr>
        </tbody>
      </table>
    </form>
  );
}

export default Form;
