Need to have current versions of nodejs, JDK8, xCode.
Must have android paths set up in $PATH env variable.
Run things with npx, which uses an online version of react-native somehow. For example:
npx react-native run-ios
https://docs.amplify.aws/start/getting-started/setup/q/integration/react-native
just run amplify init
and follow the wizard
To run in emulator, must have android emulator set up in AVD and run it first! Need to set up iphone sim in xCode also.
// pick one...
npx react-native start
npx react-native run-ios
