To add another method to the resource you can define a new one below the route resource definition on the "routes/web.php" file. For an example, you can see the command below where it's creating a new controller called "ArticleController" and having the "-r" flag which stands for "resource".
php artisan make:controller ArticleController -r
By default it will have all the "index", "create", "store", "show", "edit", "update" and "destroy". Now if you want to add a new method to the existing resource you can define a new method such as the following.
class ArticleController extends Controller
/* Your other codes here */
public function trending()
// your code logic here
Now from your "routes/web.php" file you can define your route resource as follow.
Route::get('articles/trending', [\App\Http\Controllers\ArticleController::class, 'trending']);
If you want to view all of your routes available from within the application then you can run the route:list command.
php artisan route:list
