Part III. Making a Website
Part II was a quick tour of FastAPI, to get you up to speed quickly. This part will go wider and deeper into the details. We’ll build a medium-sized web service to access and manage data about cryptids—imaginary creatures—and the equally fictitious explorers who seek them.
The full service will have three layers, as I’ve discussed earlier:
- Web
-
The web interface
- Service
-
The business logic
- Data
-
The precious DNA of the whole thing
Plus the web service will have these cross-layer components:
- Model
-
Pydantic data definitions
- Tests
-
Unit, integration, and end-to-end tests
The site design will address the following:
-
What belongs inside each layer?
-
What is passed between layers?
-
Can we change/add/delete code later without breaking anything?
-
If something breaks, how do I find and fix it?
-
What about security?
-
Can the site scale and perform well?
-
Can we keep all this as clear and simple as possible?
-
Why do I ask so many questions? Why, oh why?
