text: Title: RFE: integration with FastAPI/Starlette
  Body: [FastAPI ](https://github.com/tiangolo/fastapi)is rapidly gaining popularity as an API framework. It would be great if there was an integration client for FastAPI like there is for Flask etc.
  
  FastAPI doesn't have a plugin system like Flask, but Starlette supports middlewares, and FastAPI supports dependency injection, so I think it should be possible.
