flask-restx VS apispec

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:

apispec is not a framework, but a library that provides a Pythonic interface to OpenAPI constructs. It has multiple integrations with different tools and frameworks, including Flask, Pyramid, aiohttp, and Falcon. The list of integrations is available on the ecosystem page.
