This project was developed for learning purposes only. It's a full complete TODO List API with documentation, based on Python 3.6+ type hinting system, FastAPI framework, TortoiseORM and a Relational database (SQLite or PostgreSQL for production). This project adopts the Clean Architecture principles, I also tried to apply all good software engineering related to Python good practices and clean code.

• Python 3.6+
• Poetry

poetry install --dev

pytest app/

uvicorn app.main:app --reload

• Python 3.8
• FastAPI async python web framework
• Tortoise async python ORM
• Pytest test environment
• Poetry python package manager

As the name suggests, FastAPI is one of the fastest Python Web Frameworks around. It's modern, uses the new Python Typing hinting feature to do validations of data and saves a lot of code. Also it's perfomance is proven by various benchmarks. By allowing async programming through async/await syntax, I could use a ORM (based in Django) called Tortoise, that is fast and also Asynchronous.

As mentioned, this project was constructed used a very famous code pattern: Clean Architecture. In this aproach, the responsabilities of each layer are very strict of its particular objectives:

• Endpoints -> API Views that receives parameters, checks it's input validity, authentication, and delegates it to a UseCase classes, that will work with business logic
• UseCases -> Receives validated data from the endpoint views and perform the business logic, doing calculations and acessing resources, then, returning it to the view
• Repositories -> It's a form of resource that communicates with the database, in this project, here we use the TortoiseORM to make operations
• Schemas -> Data classes that are smart enough to make validations and serializations across all of the layers

Respecting this architecture gives the code base a very transparent and consise logic. Without hidden stuff.
