Building the To-Do API

To manage to-dos, we need an API that provides functionality to create a new to-do, retrieve a to-do or to-dos, update a to-do, and delete a to-do (i.e., an API that has CRUD functionality). We’ll do this by creating a to-do blueprint with a route per CRUD function.

CRUD functionality

CRUD stands for Create, Read, Update, and Delete, and is used to describe a set of functionalities. It is often used to describe the functionality of RESTful APIs. Typically, for a RESTFul API, the Create route uses the POST HTTP method, Read uses GET, Update uses PUT, and Delete uses DELETE.

Creating the blueprint

The blueprint itself can be created with the following code in backend/src/backend/blueprints/todos.py:

from quart import Blueprint
blueprint = Blueprint("todos", __name__)

The blueprint then needs to be registered with the app, by adding the following to backend/src/backend/run.py:

from backend.blueprints.todos import blueprint as...
