UrlPattern #

Route is built around UrlPattern a class that matches, parses and produces URLs. A UrlPattern is similar to a regex, but constrained so that it is reversible, given a UrlPattern and a set of arguments you can produce the URL that when parsed returns those same arguments. This is important for keeping the URL space for your app flexible so that you can change a URL for a resource in one place and keep your app working.

Route lets you use the same URL patterns for client-side and server-side routing. Just define a library containing all your URLs.

As an example, consider a blog with a home page and an article page. The article URL has the form /article/1234. We want to show articles without reloading the page.

Routing #

On the browser, there is a Router class that associates UrlPatterns to handlers. Given a URL, the router finds a pattern that matches, and invokes its handler. The handlers are then responsible for rendering the appropriate changes to the page.
