Inside that directory, you can run several commands:
npm start
Starts the development server.
npm run build
Bundles the app into static files for production.
npm test
Starts the test runner.
npm run eject
Removes this tool and copies build dependencies, configuration files
and scripts into the app directory. If you do this, you can’t go back!
We suggest that you begin by typing:
cd awesome-project
npm start
Happy hacking!

Compiled successfully! You can now view awesome-project in the browser. Local: http://localhost:3000 On Your Network: http://192.168.3.3:3000 Note that the development build is not optimized. To create a production build, use npm run build.
ブラウザで上記の表示が出れば無事起動できています。
Control+C でサーバーを停止します。
