Login or Signup

In order to start Expo server, you would need to be registered.

$ expo login

$ expo signup

Running the app in a local server

Expo Development CLI provides, out of the box, a way to start a local server for your app and give your a URL to it. Just execute the expo start command from Expo Development CLI and the application will start. To see all options available execute expo start --help.

The server will continue running until you stop it with expo stop. Use expo logs to view logs.

Also you can specify type of protocol to use with --exp, --http (default) or --redirect options. You can choose type of host to use with too with --lan, --localhost or --tunnel (default) options. That last one allow you to view your app on other network.

$ expo start --dev [options]

Running the app in your simulator

Expo Development CLI also provides a way to opens your app in Expo app in a currently running iOS simulator on your computer, or on a connected Android device.

$ expo start --ios [options]

$ expo start --android [options]

Note: If you will use an Android emulator, you will probably need to configure the ANDROID_HOME and PATH env variables to make it works correctly.
