The router is the backbone of your application. Trust me, that's how it is and I can prove it. One of the fundamental ideas in Web is the URL (Uniform Resource Locator).

The router is the front office that accepts the request to particular URL and wires it to a logic. Logic for generating HTML or JSON response or something else. So, the router is very important part of your system.

console.warn. In the unit tests this is happening quite often so I want to suppress it. Also I want to verify that it happens on the right place.
