4. Structuring Real-World React Projects

Setting Up Your React Development Environment Choosing a Code Editor for React Development Organizing the Project Folder Structure Working with the Terminal in React Development Starting and Running a React Project with Vite React Project Setup Wrap-Up

Starting and Running a React Project with Vite

Step 6: Initialize the Project

To set up the project, use the terminal. Open the terminal in your code editor (if it's not already open), run the following command, and press Enter:

python

When prompted, select React as the framework using the arrow keys:

Then, choose either JavaScript or TypeScript, depending on your preference:

After the setup is complete, Vite will prompt you to install dependencies. Run the following command:

python

Once the installation is done, start the development server by running:

python

After running these commands, you'll see a local development URL — typically: http://localhost:5173/. You can open this link in your browser to view the app live.

Step 7: Begin Customizing

The project is set up, you can begin customizing it:

Your main work will happen inside the src folder;
You'll find default files like App.jsx and main.jsx, which you can modify or replace based on your project's needs;
If you worked previously in CodeSandbox, recreate your familiar structure: ensure you have a main.jsx (the Vite equivalent of index.js) as the entry point and build your main application in App.jsx;
Create additional folders as needed to organize your components, styles, and assets.
