What are the best practices for deploying a React app using CLI?

When deploying a React app using CLI, consider the following best practices: 1. Optimize your build with npm run build. 2. Use environment variables for configuration. 3. Ensure proper routing with a server like Nginx or Apache. 4. Implement HTTPS for security. 5. Monitor performance and errors post-deployment.

How can I optimize my build for production?

To optimize your build for production, use the npm run build command, which creates a minified version of your app. Additionally, consider code splitting, lazy loading components, and using tools like Webpack for further optimization.

What should I do about environment variables?

For environment variables, create a .env file in your project root and define your variables there. Use process.env.REACT_APP_YOUR_VARIABLE in your code to access them. Make sure to add .env to your .gitignore to keep sensitive information secure.

Is it necessary to use a server for deployment?

Yes, using a server is essential for serving your React app. You can use services like Vercel, Netlify, or traditional servers like Nginx or Apache to host your app and manage routing.
