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 ( Python - asyncpg)

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