Structuring in FastAPI applications

For this chapter, we’ll be building an event planner. Let’s design the application structure to look like this:

planner/
  main.py
  database/
    __init__.py
    connection.py
  routes/
    __init__.py
    events.py
    users.py
  models/
    __init__.py
    events.py
    users.py

The first step is to create a new folder for the application. It will be named planner:

$ mkdir planner && cd planner

In the newly created planner folder, create an entry file, main.py, and three subfolders – database, routes, and models:

$ touch main.py
$ mkdir database routes models

Next, create __init__.py in every folder:

$ touch {database,routes,models}/__init__.py

In the database folder, let’s create a blank...
