Asyncpg

#Introduction

#

You’ll build an asynchronous product management API and leverage FastAPI’s async capabilities and connection pools to efficiently manage database connections, ensuring your API can scale and handle high traffic with ease.

#.env

We don’t need python-dotenv, use uv run with --env-file, and your env vars from .env get loaded.

For example, if we’ve got a FastAPI project we can run it locally with env vars like:

uv run --env-file .env fastapi dev

You can specific different env files for different environments, like .env.dev, .env.prod, etc.

uv run --env-file .env.dev fastapi dev

#Product Management API

• Building an Async Product Management API with FastAPI, Pydantic, and PostgreSQL

Create database product ( asyncpg)

uv run --env-file .env src/main.py

#Pending

• FastAPI AsyncPG
• Using Asyncpg with FastAPI and Air
• Lifespan state not implemented in pytest?
