The article explains why a FastAPI backend should move from a single main.py file to a responsibility‑layered architecture, detailing the recommended directory layout, pydantic‑settings configuration, SQLModel SQLite integration, APIRouter modular routing, and the resulting test coverage.
This article walks through the complete design and implementation of an intelligent attendance system that uses face detection, face encoding comparison, and liveness verification with the Python face_recognition library, OpenCV, FastAPI, SQLModel, and WebSocket communication, providing end‑to‑end code samples for backend APIs, database schema, and interactive front‑end pages.
This article walks through the complete design and implementation of a daily news summarizer, covering source selection, web‑scraping with BeautifulSoup, database schema with SQLModel, LLM‑based summarization, FastAPI endpoints, front‑end layout, category/date browsing, and a scheduled update loop.
This article introduces six Python libraries—FakerX, Prefect 3.0, SQLModel, Litestar, Robocorp, and Typer—explaining the problems they solve, providing concrete code examples, performance highlights, and practical advice for integrating them into modern Python projects.
