The URL of the request that resulted in this page being rendered.

The route matcher (e.g. /blog/:id) that the request matched for this page to be rendered.

The parameters that were matched from the route.

For the /foo/:bar route with url /foo/123, params would be { bar: '123' }. For a route with no matchers, params would be {}. For a wildcard route, like /foo/:path* with url /foo/bar/baz, params would be { path: 'bar/baz' }.

Additional data passed into HandlerContext.render. Defaults to undefined.
