UI Flows from OpenAPI specs

As a developer (and Indie Hacker), I've found myself over and over again doing the same page flows every time I need to create an app.

Login, Registration, Email Confirmation, Social Integration, Profile, Settings, Legal, FAQ/Documentation.

If you see, most of this pages are just APIs with buttons and links, so this is my idea:
Use OpenAPI specs and build HTML/React apps that use those endpoints from templates. I see it as FrontEndDev as a Service.

What do you think?
