I found this article quite useful
https://docs.moodle.org/dev/Setting_up_your_development_environment_for_Moodle_Mobile_2
Debugging with Chrome browser works well with either ionic serve or any other server (in our case we use a docker web server)
Single signon appeared to be a problem at first if the Moodle site requires sign on in the mobile browser (I didn't manage to get Chrome to support this), but as long as another Chrome browser window was logged into the web version of the site being tested the cookies and app worked fine.
If you want to develop/test on Android and IOS then if you have an OS X computer you might want to look at https://www.bitrise.io/ I plan to set up dev/test environment this weekend, so will report back if I remember it's free for up to 2 users and 1 concurrent build, and runs android in a docker container.
All the best
