This is your go-to for building REST APIs and microservices in Python when you want control over your stack without Django's overhead. The skill covers the application factory pattern for production apps, blueprints for organizing routes into modules, and Flask-SQLAlchemy integration for database work. It includes practical patterns for request handling, error responses, and pagination. Flask shines when you need something lightweight that gets out of your way, and this skill gives you the working patterns rather than just hello world examples. The blueprint structure alone will save you from messy monolithic app.py files as your API grows.

Flask - Lightweight Python Web Framework
Overview
Flask is a micro-framework for Python web development, designed for building microservices, REST APIs, and flexible web applications. Its minimalist core and extensive extension ecosystem make it ideal for projects requiring lightweight architecture, rapid development, and full control over components.
Key Features:
- Micro-framework philosophy (minimal core, extensible)
- Flask-RESTful for API development
- Blueprints for modular application structure
- SQLAlchemy integration via Flask-SQLAlchemy
- Jinja2 templating engine
- Built-in development server with auto-reload
- Werkzeug WSGI toolkit foundation
- Large extension ecosystem (Flask-Login, Flask-JWT, Flask-CORS)
- Production deployment with Gunicorn/uWSGI
Installation:
# Basic Flask
pip install flask
# Flask with common extensions
pip install flask flask-restful flask-sqlalchemy flask-login flask-cors
# With database support
pip install flask flask-sqlalchemy psycopg2-binary # PostgreSQL
# Full microservices stack
pip install flask flask-restful marshmallow flask-jwt-extended redis
