What are create-react-app's main functionalities?

Project Initialization

This command initializes a new React project in a directory called 'my-app'. It sets up the project structure, installs dependencies, and configures the build tools.

npx create-react-app my-app

Development Server

This command starts a development server that serves your React application. It supports hot reloading, so changes to your code are reflected in the browser without needing a full page refresh.

npm start

Build for Production

This command creates an optimized production build of your React application. It bundles the code, minifies it, and prepares it for deployment.

npm run build

Running Tests

This command runs the test suite for your React application using Jest. It watches for changes and re-runs tests automatically.

npm test

Ejecting

This command ejects the configuration files from create-react-app, allowing you to customize the build setup. This is a one-way operation and is not recommended unless you need to make advanced customizations.

npm run eject
