Consume Flask routes for HTTP triggered Azure Functions

[asavaritayal]

Feature Idea - Looking for votes and/or user input to gauge traction.

High level idea is to enable users to bring their Flask app and run each of the individual routes as HTTP triggered functions.

Can be implemented in either of two ways -

1. Add support for routes in the programming model, so user can maintain portability b/w Flask framework and Azure Functions.

2. Enable tooling support to convert routes to the traditional Functions programming model (HTTP accessible via method attributes).

Great idea - Lambda provides a seamless experience with Flask today. Wrapping it with Nginx or a WSGI compliant server gives good performance.

I have been working on similar approach to this library (https://pypi.org/project/lambdarest) for Azure Functions that is WSGI compliant.

You can check out the PyPI package here: https://pypi.org/project/functionapprest/

This would be a version of the HTTP trigger and output.

If you could set the WSGI application as the script entry point, get given a WSGI request and automatically have the response handled as an HTTP output then you could use Flask/Django/... web framework.

I've written a small Python package to convert Azure Functions requests/responses into WSGI. I got it working with a boilerplate Django app in production. No reason it wouldn't work with Flask, either.

I'm not sure if I properly handled error states -- this was more "proof of concept" than "battle-hardened deployment strategy". That said, I'm open to contributing the code back to this project, or simply taking bug reports / feature requests as a standalone package.

This please! Not necessarily flask but WSGI.
