Question 1

Should I use Flask or Django for my web app?

Accepted Answer

Choose Flask for flexibility and minimalism if you prefer picking your own tools and building from scratch. Django is better for rapid development with built-in features like an admin panel and ORM, but it's more opinionated.

Question 2

How to add user authentication in Flask?

Accepted Answer

Use community extensions like Flask-Login or Flask-Security for authentication. These require setup and configuration, as Flask doesn't include built-in auth, so you'll need to integrate them with your database and views.

Question 3

What are the best Flask extensions for building a REST API?

Accepted Answer

Popular choices include Flask-RESTful or Flask-RESTX for structured API development, and Flask-JWT-Extended for token-based authentication. These extensions simplify API creation but require additional learning and setup.

Question 4

How to deploy a Flask app to production?

Accepted Answer

Deploy using WSGI servers like Gunicorn or uWSGI with a reverse proxy like Nginx. Flask's minimal design means you need to handle configuration, environment variables, and scaling manually or with cloud services.

Question 5

Can Flask handle high-traffic applications?

Accepted Answer

Yes, Flask can scale to high traffic with proper architecture, such as using asynchronous workers or integrating with task queues. However, its performance depends on your implementation and extensions, unlike some frameworks with built-in optimizations.
