Can you explain what do you understand by below route configuration?

Code Snippet:


const routes: Routes = [
  { path: 'home', component: HomeComponent },             // Route 1
  { path: 'products/:id', component: ProductComponent },  // Route 2
  { path: '', redirectTo: '/home', pathMatch: 'full' },  // Route 3
  { path: '**', component: PageNotFoundComponent }        // Route 4
];

Answer By Starting like this: This is an Angular routing configuration that defines how different URLs should be handled in an Angular application.

And elaborate each route definition:

1.{ path: 'home', component: HomeComponent }

2. { path: 'products/:id', component: ProductComponent }

  • This is a dynamic route with a parameter :id
  • The :id is a placeholder that can be any value
  • For example: http://yourapp.com/products/1 or http://yourapp.com/products/xyz
  • The ProductComponent can access this ID value in its code

3. { path: '', redirectTo: '/home', pathMatch: 'full' }

  • This handles the empty path (root URL)
  • When someone visits just http://yourapp.com, they’ll be redirected to /home
  • pathMatch: 'full' means the redirect only happens for the exact empty path`

4. { path: '**', component: PageNotFoundComponent }

  • This is a wildcard route that catches all URLs that don’t match any other routes
  • If someone visits a non-existent route, they’ll see the PageNotFoundComponent
  • The ** means "match anything"
  • This should always be the last route in the array
