Routing in Angular 2: Find all paths beginning with a specific prefix

I am trying to configure the Angular router to match any path that starts with a specific prefix and route it to a component. Below is my current router setup:

  {
    path: 'posts/:id/:title',
    component: PostDetailsComponent
  }

Everything works fine when I navigate to a route like

/posts/1/json-web-token-(jwt)-authentication-with-asp.net-core-2.0

using router.navigate(), but I encounter an error when I try to refresh the page:

 Cannot match any routes. URL Segment: 'jwt'
   Error: Cannot match any routes. URL Segment: 'jwt'
    at ApplyRedirects.noMatchError (router.js:1719)

I have explored a solution suggested here, but it did not work for my specific case. I also attempted to modify my router configuration to:

  {
    path: 'posts/:id/**',
    component: PostDetailsComponent
  }

However, this resulted in an error during the build process. Is there a way to successfully match any route that starts with /posts/:id/?

Answer №1

If you're looking to match routes beyond a specific prefix, you can utilize the special '**' catchAll in a nested route:

{
    path: 'posts',
//or with :id
//  path: 'posts/:id',
    children: [
        {
          path: '**',
          component: PostDetailsComponent
        }
    ]
    
}

This setup will cover all routes starting with the "posts" prefix, like

posts/8634986/json-in-urls-rockz-or-not

or

posts/my/path/is/longer/than/yours

.

Keep in mind that by using this method, you may miss out on some of Angular Router's functionalities such as params. Additionally, it only works with URLs that comply with Angular Router's definition of validity. To access the actual URL, you'll need to utilize Router.url.

It seems like I may have stumbled upon a solution inadvertently. By eliminating any special characters from the title and substituting spaces with hyphens, I was able to revamp my URL generation logic as follows:

const cleanTitle = title.toLowerCase()
  .replace(/\s\s+/g, '-') // replacing repeated white spaces with hyphen
  .replace('(', '')
  .replace(')', '');
this.router.navigate([`/posts/${id}/${cleanTitle}`]);

Following this adjustment, the routing configuration began successfully matching URLs such as

/posts/1/efficient-data-encryption-in-java-using-aes-algorithm
