You\u2019ll need to have Node >= 6 on your local development machine (but it\u2019s not required on the server). You can use nvm (macOS\/Linux) or nvm-windows to easily switch Node versions between different projects. To create a new app, you may choose one of the following methods:<\/p>\n

npx<\/strong><\/p>\n

npx create-react-app my-app<\/p>\n

npx comes with npm 5.2+ and higher.<\/p>\n

npm<\/strong><\/p>\n

npm init react-app my-app<\/p>\n

npm init <initializer> is available in npm 6+<\/p>\n

Yarn<\/strong><\/p>\n

yarn create react-app my-app<\/p>\n

yarn create is available in Yarn 0.25+<\/p>\n

Output<\/strong><\/p>\n

Running any of these commands 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:<\/p>\n

my-app<\/p>\n

No configuration or complicated folder structures, just the files you need to build your app. Once the installation is done, you can open your project folder:<\/p>\n

cd my-app<\/p>\n

Scripts<\/strong><\/p>\n

Inside the newly created project, you can run some built-in commands:<\/p>\n

npm start or yarn start<\/p>\n

Runs the app in development mode. Open http:\/\/localhost:3000 to view it in the browser.<\/p>\n

The page will automatically reload if you make changes to the code. You will see the build errors and lint warnings in the console.<\/p>\n

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.<\/p>\n

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.<\/p>\n

The build is minified and the filenames include the hashes. Your app is ready to be deployed.<\/p>\n","protected":false},"excerpt":{"rendered":"
