What will you learn?

Part 1

In this first part, you'll learn how to develop a RESTful API with Python, Django, Django REST Framework, and Postgres. You'll containerize Django and Postgres to run inside Docker containers and configure pytest in order to practice Test-Driven Development (TDD).

Part 2

In the second part, you'll start by deploying Django, Gunicorn, and Postgres to Heroku with Docker. You'll then continue to build out the RESTful API as you write unit and integration tests. Finally, we'll look at how to document the API with Swagger.
