Verifying Angular JS Routing: Ensuring the Current URL Matches the Route, including Dynamic URL Parameters

Question

Verifying Angular JS Routing: Ensuring the Current URL Matches the Route, including Dynamic URL Parameters

Just setting this up:

app.config(['$routeProvider',function($routeProvider) {
  $routeProvider
  .when('/asd/:id/:slug',{
    templateUrl:'views/home/index.html',
    controller:'Home',
    publicAccess:true,
    sessionAccess:true
  });

:id and :slug are both dynamic parameters.

Now, I want to

validate if the current URL matches

that particular route (/asd/:id/:slug)

For instance, consider the URL: asd/5/it-is-a-slug

What is the simplest way to achieve this?

I tried the following:

$rootScope.$on('$routeChangeStart', function(){ 
   console.log($route.current); 
});

However, sometimes it doesn't log anything in the console while switching between page routes.

Utilize the current route to implement regular expressions. Include the $route service and investigate the current route object, specifically the regexp section:

$route.current.regexp

Here is an example of how you can utilize it (in a controller method to determine if the current menu item with dynamic components should be activated):

$scope.isActive = function (path) {
    if ($route.current && $route.current.regexp) {
        return $route.current.regexp.test(path);
    }
    return false;
};

Here's a suggestion to try:

  $routeProvider.when('/abc/:id/:title', {
    templateUrl: '/views/template.html',
    controller: 'YourController',
    resolve: {
      info: ['$route', 'ValidationService',
        function ($route, ValidationService) {

          var id= parseInt($route.current.params.id, 10);
          var title= $route.current.params.title;

          ValidationService.validateParams(id, title);
        }
      ]
    }
  });

You can then use the ValidationService to verify the parameters, possibly using regular expressions.

Although not the most graceful solution, I have only experimented with it in Chrome DevTools and found that it appears to be effective:

Object.getPrototypeOf($route.current) === $route.routes['/asd/:id/:slug'];

It appears that the $routes service's routes property is an object literal with keys corresponding to the patterns for each route.

For those interested in using this method, simply replace '/asd/:id/:slug' with the pattern you used when defining your route.

If you need to match the otherwise path, use $route.routes['null'].

Disclaimer: This workaround I discovered may work for me, however, since this behavior is not documented and hasn't been tested thoroughly in all scenarios, proceed with caution if you choose to utilize it.
