How to set up reactjs project

Step 1:
Install Node.js and npm Before setting up your React project, make sure you have Node.js and npm (Node Package Manager) installed on your computer. Node.js official website (https: https://nodejs.org).

Step 2: Create a new react project
After installing Node.js and npm, you can create a new React project using Create React App (CRA). CRA is a command line tool that sets up a new React project with basic project structure and configuration.

1. Open a terminal or command prompt.
2. Navigate to the directory where you will create your React project.
3. Create a new React project named "my-app" by running the following command:
npx create-react-app my-app

(Note: Replace "my-app" with any project name. ) CRA will generate the necessary files and install the required dependencies for your React project.

Step 3: Understand project structure
Once the project is created, use Terminal or Command Prompt to navigate to the project directory.
cd my-app

The project directory has the following files and folders:

src folder: React application's source code is located in the folder src.
public folder: The "index.html" HTML template file is located in this folder and is used to render React apps. React is used to create SPA apps because of this file.
package.json file: This file contains your project configuration and dependency list.

Step 4: Start the React development server
To see your React application in action, start the React development server.

1. Make sure you are in the project directory in a terminal or command prompt.
2. Start the development server by running the following command:
npm start

Your code will be compiled by the React developer server, the required files will be packaged, and the local developer server will be launched at http://localhost:3000.

Step 5:View the React application you are using in browser
Open a web browser, then go to http://localhost:3000, to view your React application.

You should see the default React logo and some sample content.

Congratulations! You have successfully set up a React project. You can now start modifying the code in the src folder to build your React application. Any changes you make will automatically trigger a live reload in the browser, allowing you to see the updates in real-time.

Remember to refer to the Create React App documentation (https://create-react-app.dev) for more details on customizing your project configuration and additional development tasks.
