GraphQL vs REST
GraphQL is trendy, but REST is battle-tested. Choose based on your needs, not hype. FastAPI excels at REST, but Strawberry brings GraphQL if you need it.

Pydantic Validation is Magic
The way Pydantic handles validation in FastAPI is incredible. Define your model with type hints, and boom - automatic validation, serialization, and documentation. No more writing validation code by hand!

Type Hints Changed My Life
I used to think type hints were just extra typing (pun intended). But after using FastAPI, I see how they enable incredible tooling - better autocomplete, automatic validation, and self-documenting code.

Never hardcode secrets! Use environment variables and pydantic-settings to keep your API keys, database URLs, and JWT secrets safe. It's Security 101.

The ORM vs Raw SQL Debate
ORMs like SQLAlchemy add abstraction but can hide performance issues. Know when to use the ORM and when to drop to raw SQL. Both have their place.

Some of My Favorite Horror Movies
I love horror movies and practical effects. One of my favorites is 'The Thing'. Hereditary is a great modern one, but most people have seen it. One modern one I really liked that not as many people have seen is 'The Night House'. It's a slow burn but really effective. More psychological than jump-scare based.

Movie Quotes!
'You wanna know how I did it? This is how I did it, Anton. I never saved anything for the swim back.' - 'Gattaca'. One of my favorite movies of all time. As silly as it sounds, that movie is actually one of the main reasons I decided to pursue an internship at NASA back in college. After that internship, I found I had a craving to learn and do more. It pushed me to take programming more seriously, which eventually led me to where I am today... Which is writing a blog post about FastAPI that's just meant to fill space. TLDR: I watched Gattaca and now I'm writing sample blog posts at 3am on a Saturday for this FastAPI tutorial. And you can too!

From Flask to FastAPI
I made the switch from Flask to FastAPI last month. The learning curve was minimal, and the benefits are huge. Automatic OpenAPI docs, better performance, and native async support. No regrets!
