fastapi VS flask-restx

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

Fast API.

We will create our API using FastAPI, a modern high-performance web framework for building fast APIs with Python. It is designed to be easy to use, efficient, and highly scalable. Some key features of FastAPI include:

FastAPI is a modern, fast, web framework for building APIs with Python 3.7+ based on standard Python type hints. It is designed to be easy to use, fast to run, and secure. In this blog post, we’ll explore the key features of FastAPI and walk through the process of creating a simple API using this powerful framework.

FastAPI is a modern, fast web framework for building APIs with Python 3.7+ that automatically generates OpenAPI and JSON Schema documentation. While FastAPI simplifies API development, manually creating and updating API documentation can still be a time-consuming task. In this blog post, we’ll explore how to leverage FastAPI’s automatic documentation generation capabilities, specifically focusing on Swagger and ReDoc, and how to streamline the process of documenting your APIs.

When it comes to Flask, in particular, there’re plenty of choices. And in fairness, not all frameworks are created equal. You’ve got flasgger, restx (successor of flask-restplus), flask-RESTful, and flask-smorest, to mention a few. How do you choose among those???

Flask-RESTX is an extension that adds support for quickly building REST APIs - GitHub - python-restx/flask-restx

Dependendo da linguagem, existem algumas ferramentas que auxiliam na geração automática das docs do Swagger. Por exemplo, no Python+flask existe o flask-restx

However, after following [the example](https://github.com/python-restx/flask-restx/tree/88497ced96674916403fa7829de693eaa3485a08/examples/zoo_app), [more complex tutorials](https://github.com/TheMorpheus407/Tutorials/tree/master/Flask/RestplusAPI) or other [basic tutorials](https://blog.ordix.de/rest), I still only receive 404s when calling get on /api or the endpoints I tried to define.

I have a flask app which is a REST API endpoint built using flask-restx. The APIs are organized neatly using namespaces. I now need to add a new set of API to access mysql data and flask-rest-jsonapi seems to be good fit for it. However I would like to add these new APIs implemented inside a flask-restx namespace.

But if you are using a Flask based app, I recently tried Flask-RESTX library which includes some great features:
