Create React App: Bootstrap React projects (deprecated)
Zero-configuration React scaffolding tool with preconfigured toolchain.
Learn more about Create React App
Create React App is a command-line scaffolding tool that generates preconfigured React project boilerplates with zero manual setup required. It abstracts the complexity of webpack bundling, Babel transpilation, and development server configuration into a single dependency managed through react-scripts. The tool provides a standardized project structure with hot module replacement for development, optimized production builds with code splitting and minification, and integrated testing infrastructure using Jest. Projects created with this toolchain can be ejected to expose the underlying configuration files, allowing developers to customize webpack and Babel settings when needed. The opinionated default configuration prioritizes convention over configuration, trading flexibility for immediate productivity and consistent build tooling across React projects.
Zero configuration approach
Build tools and configuration are preconfigured and hidden from the developer. The generated project contains only application source files and public assets, with tooling abstracted into dependencies.
Integrated development workflow
Includes built-in commands for development (npm start with hot reloading), testing (npm test with watch mode), and production builds (npm run build with minification). No separate tool installation or configuration needed.
Deprecation status
The project entered long-term stasis as of 2021. The maintainers recommend migrating to alternative React frameworks for new production applications, though it remains functional for learning and existing projects.
