Reproduction steps

The reproduction branch contains a project with two test, both of them are passing, but the the first one is set to fail using test.fails.

In a situation where you have to match an unknown port, atttempt to match it in MSW with something like this:

import { setupServer } from "msw/node";
import { http, HttpResponse } from "msw";

const server = setupServer(
  http.get("http://localhost:*", () => HttpResponse.text("Hello world!")),
);

server.listen();

Then attempt to fetch something from localhost endpoints with random ports:

const res = await fetch("http://localhost:3000");
const result = await res.text();

Current behavior

Currently the library for matching the endpoint, path-to-regexp, seems to detect this as the parameter:

If I remove the colon it acts as expected.

Expected behavior

Regardless of whether the wildcard is used with or without colon it should achieve a similar result:

• localhost:*
• localhost*

I.e. for this use case it should work. Except that in the latter pattern I would expect the hostname to not only match localhost, but also localhostable etc., so I consider it to be a workaround rather than a solution.
