To get started with react-native and clojurescript please refer to my previous blogs(https://anish-patil.blogspot.com/2019/02/how-to-create-react-native-project-with.html)
For debugging react-native, I am using https://github.com/jhen0409/react-native-debugger, on Fedora(Linux) desktop. React native debugger is available on binary format and can be found on (https://github.com/jhen0409/react-native-debugger/releases)
However for RN-debugger, one needs to turn on debugger options on Android emulator, to do that run following command in terminal
adb shell input keyevent 82
This will start debugging options menu on android emulator as follows
Choose "Debug JS Remotely" for RN-debugger.
Note if you are not using android-emulator and using phone directly then you need to shake your phone to above options!
Happy Lisping/Clojuring!
