Deno oak supports matching types for request and response objects

Recently, I've been experimenting with Deno Oak. After reviewing some basic routing examples, I noticed that none of them utilize types for request or response.

router
  .post("/api/v1/products", addProduct)


const addProduct = async (
  { request, response }: {
    request: any;
    response: any;
  },
) => {
  const body = await request.body();

  if (!body.value) {
    response.status = 404;
    response.body = {
      success: false,
      msg: "No data",
    };
  }

In the above example, both the request and response are declared as being of type any. I attempted to substitute them with the following types that unfortunately proved incompatible with the body:

import { ServerRequest, ServerResponse } from "http://deno.land/x/oak/mod.ts";

If anyone can guide me towards a relevant example or provide further information on this topic, I would greatly appreciate it.

When working with Deno, you will come across types such as <code>ServerRequest
and ServerResponse in the net module. However, Oak, a middleware framework for Deno, uses Request and Response.

const addProduct = async (
  { request, response }: {
    request: Request;
    response: Response;
  },
)

In Oak, the Response object includes a method called toServerResponse, which allows for conversion from an Oak Response to a Deno net ServerResponse.

/** This method converts the Oak response to the response expected by the Deno net server. It marks the response as not writable.
   * 
   * Most users will not need to use this method. */
  async toServerResponse(): Promise<ServerResponse> {
