Fastapi hello world
Level: Beginner (score: 2)
Welcome to this FastAPI learning path. In the next 10 Bites you will write a simple API to track food / calories.
Let's break this problem down in some easily digestable steps or Bite exercises:
1. Learn how to instantiate a FastAPI app instance and write your first view or endpoint < this Bite.
2. Get familiar with typing using the Pydantic library. We'll make a Food model which we'll use throughout this Learning Path.
3. Create food objects. To keep things simple we will use a simple list of Food objects in memory. We'll introduce databases and relational tables in our SQLModel learning path.
4. Retrieve food objects (all or a particular one).
5. Update and delete food object. This concludes the full CRUD (create-read-update-delete) of foods.
6. Pydantic part II: define two more models: User and FoodEntry.
7. Repeat the CRUD but now for food logging.
8. Add exception handling to our API.
9. Render the food log in a basic HTML template (Yes! FastAPI can also be used as web framework!)
10. Add authentication to our API.
---
In this first Bite of the challenge, let's make a FastAPI app instance and a view that returns {"message": "Welcome to PyBites' FastAPI Learning Path 🐍 🎉"} when hitting the root endpoint (/) with a GET request (see the tests).
Some notes on this learning path:
- To use earlier solutions as template code for later exercises without spoiling anything, you must solve the exercises in order, that is completing earlier exercises unlocks later ones.
- You can make the FastAPI endpoints async or not, the tests will work either way.
Good luck and welcome onboard! We hope this will be a fun and rich learning experience.
