FastAPI with SQLAlchemy Tutorial

Code for my video tutorial FastAPI with SQLAlchemy Tutorial

What is FastAPI?

FastAPI is a high-performant REST API framework for Python. It's built on top of Starlette and it uses Pydantic for data validation. It can generate OpenAPI documentation from your code and also produces a Swagger UI that you can use to test your application.

Check out FastAPI's GitHub repository and give it a star! Also make sure to check out its excellent documentation online.

What are SQLAlchemy and Alembic?

  • SQLAlchemy is Python's most popular Object Relational Mapper (ORM). ORMs are frameworks that offer an object-oriented interface to your database tables. ORMs give you a layer of abstraction on top of SQL, so you don't have to write SQL queries by hand - instead, you just write code. ORMs also abstract away the differences between SQL engines, such as PostgreSQL and MySQL, so you can switch between one and the other without having to change your code. You can learn more about SQLAlchemy with its official documentation: https://www.sqlalchemy.org/.

  • Alembic is a database migrations management framework. Alembic ensures that your database schemas accurately reflect the data models that you define with SQLAlchemy. You can learn more about Alembic with its official documentation: https://alembic.sqlalchemy.org/en/latest/
