Dual Deployment/Development - Flask On Server & Serverless Framework?

So, I’d like to have two deployment options for the same code base (Python + JS):

  1. Deploy a traditional server-based Python web app – probably using Flask
  2. Deploy a Serverless Framework app – probably with API Gateway + Lambda + Static S3 website

I’ve seen that you can bundle a Flask app into “Serverless WSGI using API Gateway with proxied Lambda” fairly easily but that doesn’t look like a practical solution for developing with these two options. Or maybe it is?

What are my options here, if any?

Serverless WSGI utilizing Programming interface Entryway with proxied Lambda" reasonably effectively yet that doesn’t resemble a pragmatic answer for creating with these two choices. Or then again perhaps it is!
