Can angularjs routes have default parameter values?

I recognize that this question is old, but still: Why don’t you just redirect the “empty” URL to one containing the default productId?

myModule.config(['$routeProvider', function($routeProvider) {
    $routeProvider.
     when('/products/', {redirectTo: '/products/123'}).
     when('/products/:productId', {templateUrl: 'products.html', controller: ProductsCtrl})
}]);
