Serving static files

It's quite common to want to serve static files from your backend server to the frontend.

Create val
import { servePublicFile } from "https://esm.town/v/stevekrouse/utils@179-main/serve-public/index.ts";

export default async function(req: Request): Promise<Response> {
  const url = new URL(req.url);
  if (url.pathname === "/") {
    return servePublicFile("/public/index.html", import.meta.url);
  } else if (url.pathname.startsWith("/public")) {
    return servePublicFile(url.pathname, import.meta.url);
  } else {
    // normal server code here
  }
}

This requires a couple steps:

1. Handling requests for those files in your server
2. Reading those files in the right place in the project
3. Adding the correct content-type
