The Decline of Django

I second FastAPI! In my mind it's, "Flask, but better." The killer feature in my mind is that it leverages type hinting and dataclasses, using Pydantic, to take away a lot of the grindyy, boilerplate parts of writing an API, like type checking, dependency injection, generating good error messages, generating API documentation, ...

Even when I'm not using FastAPI now, I use Pydantic everywhere. Types in Python, while not nearly as useful as in a strongly typed language, are a dream come true.

Pydantic's BaseSettings has cured my configuration-DSL itch. You can type in (typed) defaults in Python and have them overidden by env vars.

And Docker secrets! It's also pretty easy to rig them up with YAML files! BaseSettings is amazing.

The only gripe I have with Pydantic is that sometimes it has really opinionated type coercion that can get you in trouble sometimes. For instance, `Union[int, float]` will accept either an int or a float, sure, but it will always output an int. This isn't difficult to fix but may only realize it after having shot yourself in the foot.
