Polymer应用程序路线：到同一页面的多个路线？

Question

Is there a built-in method for routing multiple possible links to the same "page"?

For example, I have a '/' route that loads a landing page by binding the active attribute of that route to a property named landing-active, which is being observed. The most straightforwards way I can think of to allow converging routes is to create another app-route element for the new route, and bind its active attribute to the same landing-active property as the '/' route.

Is there a better/different way of handling this, or should I stick with my method?

Edit : I tried my method out, and it doesn't work. Here's my original route:

<app-route
  id='landing-route'
  route='{{route}}'
  pattern='/'
  active='{{landing-active}}'>
</app-route>

If I then add an alternate route by simply changing the pattern and id, then the '/' route no longer works. Changing the active binding on the new route fixes this issue, but also no longer allows it to rout as intended. So my conclusion is that I can't bind the same property to the active attribute of two separate app-route elements, so my routing method doesn't work.

What alternatives do I have?

Answer 1

• Option 1: Use two separate active variables for your two <app-route> s, and test for either variable (eg, with a computed binding / property ).

• Option 2: Use a different router component. <nebula-routing> might be the best option IMO, given that it has a similar API to <app-route> and supports regular expression in the route patterns.
