### Full Stack FastAPI PostgreSQL - Recursos

* Integração completa **Docker**.
* Modo de implantação Docker Swarm.
* Integração e otimização **Docker Compose** para desenvolvimento local.
* **Pronto para Produção** com servidor _web_ usando Uvicorn e Gunicorn.

      derivedSuites.add(createSubmapSuite(parentBuilder, Bound.INCLUSIVE, Bound.NO_BOUND));

Os recursos chave são:

* **Rápido**: alta performance, equivalente a **NodeJS** e **Go** (graças ao Starlette e Pydantic). [Um dos frameworks mais rápidos disponíveis](#performance).
* **Rápido para codar**: Aumenta a velocidade para desenvolver recursos entre 200% a 300%. *
* **Poucos bugs**: Reduz cerca de 40% de erros induzidos por humanos (desenvolvedores). *
