Get Started Immediately

You don’t need to install or configure tools like webpack or Babel. They are preconfigured and hidden so that you can focus on the code.

Create a project, and you’re good to go.

Creating an App

You’ll need to have Node 14.0.0 or later version on your local development machine (but it’s not required on the server). We recommend using the latest LTS version. You can use nvm (macOS/Linux) or nvm-windows to switch Node versions between different projects.

To create a new app, you may choose one of the following methods:

npx

npx create-react-app my-app --template starter-kit

(npx is a package runner tool that comes with npm 5.2+ and higher, see instructions for older npm versions)

npm init <initializer> is available in npm 6+

Yarn

yarn create react-app my-app --template starter-kit

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

├── node_modules
├── package.json
├── .gitignore

    ├── styles/
    ├── types/
    ├── services/
    ├── utils/
    └── main.jsx
    └── app.jsx

cd my-app

Inside the newly created project, you can run some built-in commands:

npm dev or yarn dev

Runs the app in development mode. Open http://localhost:3000 to view it in the browser.

npm test or yarn test

Runs the test watcher in an interactive mode. By default, runs tests related to files changed since the last commit.

Read more about testing.

npm run build or yarn build

Builds the app for production to the 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.
