create-modern-fastapi 0.4.0

A CLI tool to create a FastAPI project.

Clean Architecture Template for FastAPI Applications

This template provides a clean and well-structured foundation for building FastAPI applications using Clean Architecture principles. It uses SQLModel as the ORM and PostgreSQL as the database. It clearly separates business logic, use cases, infrastructure, and the API layer to ensure maintainability, testability, and scalability. With an explicit project structure and built-in testing strategy, it serves as a solid starting point for developing professional and production-ready backends.

Requirements

• Python 3.10 or higher
• PostgreSQL
• uv for managing virtual environments and dependencies
• justfile for command runner
