Best practice for menu state in Angular2 / Meteor

I was wondering what the example or best practice would be for highlighting menu items as I activate a route. Currently in my sandbox app I have an app component that has a menu and presents content with router-outlet. So when a route is activate (link clicked) I want to load the new component and have the class on the appropriate menu item highlight to show selection.

I can come up with a couple of ways to do this but it occurred to me I don’t know which way in the Meteor/Angular2 world would be best. I suspect I will have this question in lots of areas for awhile but this one had me curious enough to ask.
