4## How it works
5`upgradeExpress` wraps a Web handler into a function that works as normal when called by the Web API, and redirects to the Web API when called by the Express API.

7## Example

1import { API_URL } from "https://esm.town/v/std/API_URL?v=5";
2
3export async function alias<P extends Params>(params: P): Promise<Result<P>> {
4  const username = params.username;
5  let url = `${API_URL}/v1/alias/${username}`;

1export function add(a, b) {
2  return a + b;
