Do you want to build APIs using Python? I'll show you how.
The developer experience and speed of development with FastAPI means you can build a complete, high-performance API in days, and adding new features is blazing-fast.
In this course, I'll show you how to build a social media API with user authentication. Users will be able to register and log in using Bearer (JWT) tokens. They will be able to create posts, leave comments, and like existing posts.
You'll learn how to use background tasks in FastAPI to improve performance when running slow code, such as when sending emails (which we also do).
Throughout the course we use an async database library, again to maximise performance, which is nonetheless straightforward to use. You'll learn about the different types of data relationships and how to model them.
I'll also show you how to handle file uploads and how to store them securely in a third party service, so you don't use up your own server space.
Finally, 100% of the code in this course has tests. You'll use pytest extensively to write integration and unit tests for the API. You'll learn about pytest fixtures, parametrization, and testing conventions. You'll also learn extensively about logging using the built-in Python module.
Of course, I'll show you how to deploy your FastAPI app using popular service Render.com. I'll share how to do it for free, and also how to improve performance and developer experience by going with paid options.
If you use or want to use FastAPI, this course contains everything you need to develop complete, professional-grade APIs!
