Consider redaxios
Please consider redaxios for sending api calls, setting the baseurl is much easier.

I noticed that the schema is hardcoded in, how do you test the client with it force set to https?
Thanks for the link to redaxios; I think you're right and will provide a cleaner implementation.
I believe the browser app doesn't have the https hardcoded and should work with http (without federation)
For the next mobile app release I am planning on supporting http (when not federated). I vaguely remember some global app setting requiring https, that I was recommended to set, so I am not sure how successful I will be. I will take this opportunity to utilize redaxios.
To answer your testing question, beyond the unit testing, I mostly do manual testing in the simulator with a live server. Is there a better approach I should read up on?
Thanks for your interest in the project!
