Simple Python web backend with Cosmos DB and Fast API

This python project creates a very simple three-tiered ToDo web app backend using Cosmos DB as the database and FastAPI as the python web framework to expose API endpoints for performing CRUD operations.

Features

This project demonstrates the use of the Cosmos DB python SDK with FastAPI . It covers the following aspects:

• Create Azure Cosmos DB Resource in Azure Portal
• Setup the dev environment and install requisite client-side libraries
• Store Cosmos DB Resource connection credentials on our server
• Connect to Cosmos DB Resource through python client
• Define ToDoItem data model
• Create the required database and container to store ToDo Items
• Setup for API implementation
• Write functions to interact with the database
• Expose the API endpoints with FastAPI
• Test the endpoints
