How to access env from router.post?

[OkenKhuman]

Hi I have been trying to implement D1 update using HTTP Post. When I look up the docs, I cannot find any example with itty-router's http POST function accpting env argument.

I need the env argument to access the D1 and other resources. It will be very helpful if there is example for this.

Basically, anything you pass into a router.handle will be the args presented to each handler downstream. If you pass in all the ...args from cloudflare's fetch, env will naturally be the second param, and context the third. Otherwise, it's all up to you!
