Imagine the backend is a waiter who knows the whole menu. Until now, the frontend was a customer who had to guess what was on the menu and hope for the best.
What happened
The honest-cam compliance portal has a backend (the Python server that stores and serves all the data) and a frontend (the web pages that display it). They talk to each other by sending data back and forth in a specific format.
The problem: the frontend had no way to know if that format changed. If I updated the backend and forgot to update the frontend, it would just silently break — or worse, show wrong data.
I set up an automated system that reads the backend's full list of routes and data shapes, then generates a TypeScript file for the frontend that describes exactly what to expect. Now if the backend changes and the frontend is out of date, the build fails with a clear error instead of breaking silently.
There's also a guard built in: when you save changes to the project, it checks if the types are still current. If not, it stops you.
Why
The portal has grown from a handful of routes to 39 operations, and managing the connection between frontend and backend by hand isn't sustainable. This sets up a system where both sides stay in sync automatically. Groundwork for everything that comes next.
