 * route is a the main URL builder for the API. It will use a predefined host and prefix (global)
 * in the urls.ts file and then append the passed in path parameter uring the `URL` class from the
 * browser. It will also append any query parameters passed in as the second parameter.
 *
 * The default host `http://localhost.com` is removed from the path if it is present. This allows us
 * to bootstrap the API with different hosts as needed (like for testing) but still allows us to use
 * relative URLs in production because the API and client bundle are served from the same server/host.
