How to combine client and server on a DEV machine?

I'm developing a website with Angular.js, which uses an HTTP interceptor.

When I'm running the website on a DEV machine, I want my HTTP interceptor to write each HTTP request/response into a local PostgreSQL server.

I understand very well that I am mixing up the client and server sides, but this is strictly for development purposes, and always for a single local machine.

Is there any modern/standard/recommended way to do such a thing today?
