The communication Mobile + API architecture scenario best matches what I want to implement except the mobile app must be a static React app; served by web/file server. Notice the SPA talks directly to the API.
Where can I find a working example for this architecture scenario? The linked instructions are long, so I will likely introduce multiple errors while following them. Also, the instructions are for mobile apps, not a web app, which will induce even more errors.
My hope was to start with working code.
