Nested routes example?

[yaron14]

What is the correct way for creating nested routes?
Currently I'm creating a new RoutetSlot instance in the parent component and inserting router-slot tag in the required position.

Overall it's working fine, but I noticed that I can't invoke a promise based function before initializing the router. In that case the view of the nested components is just not rendering.

Is there a better way to achieve nested routes?
