Can I use this skill to build REST APIs?

Absolutely. It includes specific patterns for JSON-based API routes, request handling, and registering blueprints with versioned URL prefixes like /api/v1.

Is this compatible with the latest version of Flask?

Yes, it is verified for Flask 3.1.x and modern dependencies including Flask-SQLAlchemy 3.1.1 and Werkzeug 3.1.3.

How does this skill handle circular imports in Flask?

It implements the 'extensions.py' pattern and application factory, ensuring that extensions like SQLAlchemy are initialized once and routes are imported only after the Blueprint is defined.

Does it support modern Python dependency managers?

Yes, the skill provides quick-start instructions and project initialization patterns specifically using 'uv' for faster, more reliable dependency management.

API開発

Builds scalable Python web applications using the application factory pattern, Blueprints, and Flask-SQLAlchemy.

概要

This skill equips Claude with the architectural patterns needed to create production-grade Flask applications. It prioritizes the application factory pattern and modular Blueprints to ensure your codebase remains maintainable and free of circular imports. From setting up environment-specific configurations and database models with SQLAlchemy to implementing secure authentication via Flask-Login and Flask-WTF, this skill covers the full lifecycle of Flask backend development. It is particularly useful for developers moving from simple scripts to professional, multi-module web architectures.

主な機能

Organizes routes, templates, and static files using modular Flask Blueprints.
Implements the Application Factory pattern to avoid global state and simplify testing.
