flask-jwt-extended VS fastapi

flask-jwt-extended, Flask extension that provides JSON Web Tokens (JWT) support;

After the maintainer of flask-jwt stopped updating his package, flask-jwt-extended was started as a new project. The author originally wanted to extend flask-jwt but instead had to create a new project. Like flask-jwt, flask-jwt-extended is opinionated, but takes things to the next level. The flask-jwt-exetended extension is very full featured and eminently configurable. It is an excellent package with a lot of activity and support.

The error you're seeing is coming from the PyJWT library, from this line, I think. jwt.encode(..) returns a string, which does not have a .decode(..) attribute/method.

He is probably most well know for creating FastAPI that I taught to some of my clients and Typer that I've never used.

It has been an interesting exercise developing this wrapper component. The fact that it seamlessly integrates with the FastAPI framework is just a bonus for me; I didn't plan for it since I hadn't learned FastAPI at the time. I hope you find this post useful. Thank you for reading, and stay safe as always.

FastAPI is a modern, high-performance web framework for building APIs with Python, based on standard Python type hints.

In this tutorial, I will demonstrate how to use Burr, an open source framework (disclosure: I helped create it), using simple OpenAI client calls to GPT4, and FastAPI to create a custom email assistant agent. We’ll describe the challenge one faces and then how you can solve for them. For the application frontend we provide a reference implementation but won’t dive into details for it.

That’s when I found FastAPI.

An API application framework (such as FastAPI)

It’s been my experience that async Python frameworks tend to turn IO bound problems into CPU bound problems with a high enough request rate, because due to their nature they act as unbounded queues.

This ends up made worse if you’re using sync routes.

If you’re constrained on a resource such as a database connection pool, your framework will continue to pull http requests off the wire that a sane client will cancel and retry due to timeouts because it takes too long to get a connection out of the pool. Since there isn’t a straightforward way to cancel the execution of a route handler in every Python http framework I’ve seen exhibit this problem, the problem quickly snowballs.

This is an issue with fastapi, too- https://github.com/tiangolo/fastapi/issues/5759
