With our custom-made ORM, we built the above, except instead of a Web Server, we scripted a CLI application to interact with our ORM.
We still need something like json-server
which can bridge the gap between front and back end and complete the Request-Response Cycle
The Web Server Gateway Interface provided by Werkzeug will be able to handle the HTTP traffic to our web server.
Although our server app will focus on requests for dynamic resources--database records--our app could also route requests for static resources, such as images, to an entirely different server.
