AngularJS flexible route parameter

My AngularJS application has routes that can be either:

www.website.com/blog/xyz
www.website.com/blog/xyz/title/other-params

In the second URL, the title parameter is used for readability purposes only and is not mandatory in the URL. Therefore, I have implemented the following AngularJS code for my routes:

$routeProvider
    .when('/blog', {
        templateUrl : url,
        controller : 'blogsHome'
    })
    .when('/blog/:blog_id', {
        templateUrl : url,
        controller : 'blogInfo'
    })
    .when('/blog/:blog_id/:url_params*', {
        templateUrl : url,
        controller : 'blogInfo'
    });

In the above code, I had to include a middle when statement because Angular requires the :url_params parameter and it cannot be empty. Is there a way to avoid having this extra middle when statement?

Inserting * into your project to handle various levels of folders dynamically and using ? for optional paths. However, if you need to deal with multiple layers that are also optional, you can try something like this ?:multipleOptionalParams*?

Give this a shot:

$routeProvider
    .when('/', {
        templateUrl : 'blog.html',
        controller : 'myCtrl'
    })
    .when('/blog/:blog_id/?:url_params*?', {
        templateUrl : 'details.html',
        controller : 'details'
    });

To modify the sequence of when conditions in order to have the second one come before the third, follow these steps:

Start with the most complex condition first:

$routeProvider
    .when('/blog', {
        templateUrl : url,
        controller : 'blogsHome'
    })
    .when('/blog/:blog_id/:url_params*', {
        templateUrl : url,
        controller : 'blogInfo'
    })
    .when('/blog/:blog_id', {
        templateUrl : url,
        controller : 'blogInfo'
    });
