Flask is a lightweight Python web framework focused on simplicity and extensibility. It powers everything from prototypes to large-scale applications like Netflix, Airbnb, and Uber's internal tools. Junior developers earn 75-85k USD, seniors 180-220k. Mastery takes 6-8 weeks if you have Python experience. It sits between Django (batteries-included, steeper curve) and bare WSGI (too low-level). Flask's advantage: you choose your stack, database, auth, ORM, rather than inheriting monolithic defaults.

Apa iku Flask Microframework

Flask is a lightweight Python web framework that lets you build web applications with minimal boilerplate. Unlike Django (which includes everything), Flask is intentionally minimal, you pick your database, authentication library, templating engine, and form validation. It's built on Werkzeug (WSGI utilities) and Jinja2 (templating). A "hello world" Flask app is 5 lines of code. Flask powers production systems at Netflix, Airbnb, and Uber. It's the go-to framework when you need flexibility over convention or when building APIs alongside a separate frontend (Vue, React, etc.).

❓ FAQ

When should I use Flask vs Django?
Flask for small-to-medium apps where you want control over architecture. Django for data-heavy apps where the admin panel, ORM migrations, and built-in auth save months. Flask is lighter, more flexible; Django is more opinionated and batteries-included.
How do I structure a large Flask app?
Use application factory pattern (create_app function), blueprints (modular route groups), and separate config/models/routes into distinct files. Avoid putting everything in a single app.py. A mature Flask codebase mirrors Django's folder structure even though Flask doesn't enforce it.
Is Flask suitable for production?
Yes. Use Gunicorn/uWSGI as the WSGI server, Nginx as reverse proxy, and proper error handling + logging. Flask powers production apps serving millions of requests. The framework itself is minimal; you add production safety via middleware and ops practices.
What's the difference between Flask-RESTful and hand-written routes?
Flask-RESTful adds Resource classes and automatic request parsing. Nice for consistency but optional. Many production apps just use @app.route() decorators. Choose based on team size and API complexity, overkill for 5 endpoints, valuable for 50+.
How do I handle async in Flask?
Flask 2.0+ supports async route handlers with async def. Use for I/O-bound tasks (API calls, database queries) but not CPU-bound work. For heavy async workloads, consider FastAPI or Quart (Flask-compatible async variant).
