Goals

provide some life cycle or event listener, so I can do something in that very time

Non-Goals

No response

Background

I want to log the total time for every incoming request. So far no easy way to do that except writing code in every route handler function.

Proposal

1. there is a serverLifeCycle.ts file in the app directory;
2. in this file, can export different life cycle, like: onAppStart, onAppReady, onAppEnd, onRequestStart, onRequestEnd, onResponseStart, onResponseEnd
3. for App life cycle, I can have some parameters to handle something related to the entire app. For request and response life cycle, I can access to the response and request object.
