A production-ready FastAPI CRUD API example with async/await, PostgreSQL, and comprehensive Pytest testing.
FastAPI CRUD Async is a production-ready example project that demonstrates how to build a fully asynchronous CRUD API using FastAPI. It solves the problem of creating scalable, non-blocking web APIs with modern Python, integrating seamlessly with PostgreSQL and providing a comprehensive testing framework. The project serves as a practical blueprint for developers implementing real-world APIs with async/await patterns.
Python developers and backend engineers building scalable web APIs with FastAPI, especially those transitioning to async/await patterns or seeking best practices for testing and Dockerized deployment.
Developers choose this project because it provides a complete, battle-tested example with async database operations, full test coverage, and Docker support, reducing the learning curve and accelerating development of production-grade FastAPI applications.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Implements async/await with SQLAlchemy for non-blocking PostgreSQL queries, demonstrating performance benefits for I/O-bound CRUD endpoints as highlighted in the README.
Uses Pytest for full coverage including unit, integration, and API tests, ensuring reliability and adherence to best practices for testable FastAPI code.
Provides Docker Compose configuration for consistent setup, reducing environment-specific issues and simplifying deployment, as shown in the build commands.
Leverages FastAPI's OpenAPI support to create interactive Swagger UI docs at the /docs endpoint, enhancing developer experience and API exploration.
The project is tailored exclusively for PostgreSQL; adapting it to MySQL, SQLite, or NoSQL databases requires significant code modifications and migration changes.
Initial setup mandates Docker, which can be a barrier for developers preferring local installations or teams using different containerization tools.
As a CRUD example, it lacks production essentials like authentication, authorization, rate limiting, or caching, requiring additional integration efforts.
