How to create simple React app step by step.

Creating a simple React app involves several steps. Before you start, make sure you have Node.js and npm (Node Package Manager) installed on your machine. If you don’t have them installed, you can download and install them from the official website

Once you have Node.js and npm installed, you can follow these steps to create a simple React app:Step1

Step 1: Open a terminal or command prompt.

Step 2: Create a new React app using Create React App. Run the following command:

  npx create-react-app my-react-app

Replace “my-react-app” with the desired name of your app.

Step 3: Change into the app’s directory:

  cd my-react-app

Replace “my-react-app” with the desired name of your app.

Step 4: Open the project in your preferred code editor. For example, if you’re using Visual Studio Code, you can run:

  code .

Step 5: Now, you can start the development server by running:

  npm start

This will launch your app in development mode, and you can view it in your browser at http://localhost:3000.

Step 6: Open the src folder in your code editor, and you’ll find the App.js file. You can modify this file to create your simple React app.

Here’s an example of a simple React app:

  // src/App.js
import React from 'react';

function App() {
  return (

Hello, React!

This is a simple React app.

); } export default App;

Feel free to customize the content in the App.js file to suit your needs.

Remember to save your changes, and you should see the updates in your browser.

This is a very basic example, and there’s a lot more you can do with React. As you get more comfortable, you can explore React’s documentation and add more features to your app.
