Initialized a git repository.

Success! Created sample-react-app at /home/vagrant/sample-react-app
Inside that directory, you can run several commands:

  yarn start
    Starts the development server.

  yarn build
    Bundles the app into static files for production.

  yarn test
    Starts the test runner.

  yarn 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 sample-react-app
  yarn start

Happy hacking!

[vagrant@localhost ~]$ cd sample-react-app/
[vagrant@localhost sample-react-app (master)]$ yarn start
Compiled successfully!

You can now view sample-react-app in the browser.

  Local:            http://localhost:3000/
  On Your Network:  http://10.0.2.15:3000/

Note that the development build is not optimized.
To create a production build, use yarn build.
