What is Create React App?

Create React App is an official React project scaffolding tool maintained by Facebook. It can quickly set up a modern React application development environment without configuration. It includes all the toolchain configurations required for developing React applications, such as Webpack, Babel, ESLint, etc.

How to use Create React App?

You can create a new project by running a simple command. The built - in development server supports hot reloading, and the test runner and production build tools are pre - configured.

Applicable scenarios

Suitable for quickly starting new React projects, learning React development, and building small and medium - sized React applications. For large projects that require highly customized configurations, other solutions may need to be considered.

Main features

Zero - configuration startup
It has the best configurations of tools like Webpack and Babel built - in, eliminating the need for manual configuration of build tools.
Development server
The built - in development server supports hot module replacement (HMR) and automatic refresh.
Test integration
It is pre - configured with the Jest test runner and supports the interactive test mode.
Production optimization
Generate an optimized production build with one click, with automatic code splitting and resource hashing.
Advantages
Quickly start new projects and save configuration time.
Officially maintained to ensure best practices and stability.
Built - in modern development toolchain.
Rich documentation and community support.
Limitations
The configuration is abstracted, and custom configuration requires ejecting.
You cannot roll back after ejecting.
It may not be flexible enough for large projects that require special build configurations.

How to use

Create a new project
Create a new project after global installation using npx or npm.
Start the development server
Enter the project directory and start the development server.
Run tests
Execute tests using the built - in test runner.
Build the production version
