Create React apps with no build configuration.
●Creating an App – How to create a new app.
●User Guide – How to develop apps bootstrapped with Create React App.
Create React App works on macOS, Windows, and Linux.
If something doesn’t work, please file an issue.
If you have questions or need help, please ask in GitHub Discussions.
npx create-react-app my-app
cd my-app
npm start
If you've previously installed create-react-app globally via npm install -g create-react-app, we recommend you uninstall the package using npm uninstall -g create-react-apporyarn global remove create-react-app to ensure that npx always uses the latest version.
(npx comes with npm 5.2+ and higher, see instructions for older npm versions)
Then open http://localhost:3000/ to see your app.
When you’re ready to deploy to production, create a minified bundle with npm run build.
npx create-react-app my-app(npx is a package runner tool that comes with npm 5.2+ and higher, see instructions for older npm versions)
npm init react-app my-app
npm init <initializer> is available in npm 6+
yarn create react-app my-app
yarn create <starter-kit-package> is available in Yarn 0.25+
It will create a directory called my-app inside the current folder.
Inside that directory, it will generate the initial project structure and install the transitive dependencies:
my-app
├── README.md
├── node_modules
├── package.json
├── .gitignore
├── public
│ ├── favicon.ico
│ ├── index.html
│ └── manifest.json
└── src
├── App.css
├── App.js
├── App.test.js
├── index.css
├── index.js
├── logo.svg
└── serviceWorker.js
└── setupTests.js
cd my-app
Inside the newly created project, you can run some built-in commands:
npm startoryarn start
npm testoryarn test
npm run buildoryarn build
build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.
The build is minified and the filenames include the hashes.
Your app is ready to be deployed.
-webkit- or other prefixes.
●A fast interactive unit test runner with built-in support for coverage reporting.
●A live development server that warns about common mistakes.
●A build script to bundle JS, CSS, and images for production, with hashes and sourcemaps.
●An offline-first service worker and a web app manifest, meeting all the Progressive Web App criteria. (Note: Using the service worker is opt-in as of react-scripts@2.0.0 and higher)
●Hassle-free updates for the above tools with a single dependency.
Check out this guide for an overview of how these tools fit together.
The tradeoff is that these tools are preconfigured to work in a specific way. If your project needs more customization, you can "eject" and customize it, but then you will need to maintain this configuration.
