Fastapi: [QUESTION] Will this framework work with Google Cloud Functions / AWS Lambda / Azure Functions?

First check

• [x] I used the GitHub search to find a similar issue and didn't find it.
• [x] I searched the FastAPI documentation, with the integrated search.
• [x] I already searched in Google "How to X in FastAPI" and didn't find any information.

Description

How can I use this framework with some serverless solutions out there (Google Cloud Functions / AWS Lambda / Azure Functions, ...)?

Thank you.

Additional context

@piavgh
FastAPI supports ASGI protocol to connect a server.

The libraries are ASGI adapter which helps to run FastAPI on the services.

For AWS Lambda:

For Azure Functions:

For Google Cloud Functions:

Example for AWS Lambda with mangum:

@koxudaxi : thank you. I will check those repos

Zeit now supports an ASGI Interface for Python.

It was fairly easy to set this up & deploy. Doesn't require making modifications to the application structure. Not sure if this would work well for most deployments (I think WebSockets would be out of question) but may be a good solution for simple apps!

I created a demo repo showcasing what I've found. Hope it can help anyone else that looks into FastAPI + Serverless: https://github.com/paul121/fastapi-zeit-now
