Web components for declarative client-side routing.

  • Parses the browser window.location for pathname and search query parameters
  • Pattern matching supports named parameters, optional sections and wildcards
  • Updates the browser URL on the client using the History API
  • Supports using parameters to interpolate URL changes
  • Can intercept anchor links and resolve on the client


$ bower install -S arsnebula/nebula-routing

Getting Started

Import the package.

<link rel="import" href="/bower_components/nebula-routing/nebula-routing.html">

Add the routing elements. The <nebula-intercept> element can intercept clicks on anchor elements that have an href that targets the local origin. Typically, you will add a single instance to your top-level application element, or the HTML body element.


The <nebula-location> element parses the window location and provides route information including pathnanme, query parameters, and the current hash. The <nebula-route> element is used to match a route path to a specified pattern.



Use something like iron-pages to perform conditional rendering of page elements:

<iron-pages selected="{{}}" attr-for-selected="name">
  <div name="test1">Test 1</div>
  <div name="test2">Test 2</div>

Use the redirect method to change the route based on a new path, or parameter:

this.$.route.redirect({page: 'test2'})

To perform a replaceState rather than pushState, set the optional replace parameter to true.

this.$.route.redirect('/test2'}, true)
this.$.route.redirect({page: 'test2'}, true)

For more information, see the API documentation.
