Angular url matcher - match any path starting with

In Angular, the URL matcher allows you to define custom URL matching patterns for your routes using the UrlMatcher class. To match any path starting with a specific segment, you can create a custom URL matcher that checks if the URL starts with the desired segment.

Here's an example of how you can create a custom URL matcher in Angular to match any path starting with a specific segment:

1. Create a custom URL matcher function:

typescriptCopy code
import { UrlMatcher } from '@angular/router';

function startsWithSegmentMatcher(url: string): UrlMatcher {
  return (segments) => {
    if (segments.length > 0 && segments[0].path.startsWith(url)) {
      return {
        consumed: segments.slice(0, 1),
        posParams: { path: segments[0] }
      };
    }
    return null;
  };
}

2. Define your route with the custom matcher:

typescriptCopy code
import { Routes } from '@angular/router';

const routes: Routes = [
  {
    matcher: startsWithSegmentMatcher('example'), // Match any path starting with "example"
    loadChildren: () => import('./example/example.module').then(m => m.ExampleModule)
  },
  // Other routes...
];

In this example, we create a custom startsWithSegmentMatcher function that takes a string url as input and returns an Angular UrlMatcher. The URL matcher function checks if the first segment of the URL starts with the provided url. If it does, the matcher returns the consumed segments and any matched path parameters (in this case, there are no path parameters).

Now, any URL that starts with /example will be matched by the custom matcher, and the associated route will be activated. For example, the following URLs will be matched:

• /example
• /example/child
• /example/another-child
• /example/some/other/path

Remember to adjust the url parameter in the startsWithSegmentMatcher function to match your desired segment.

Using a custom URL matcher allows you to create flexible route patterns that go beyond simple path matching and enables you to handle more complex route scenarios in your Angular application.
