Using slugs in route with a resource controller

https://laravel.com/docs/10.x/controllers#restful-partial-resource-routes

Slugs are important when it comes to seo friendly url. We will see how to use slugs for url instead of ID.

/**
     * Display the specified resource.
     */
    public function show(String $slug)
    {

        $post = Post::where('slug', $slug)->first();
        
        if (!$post) {
            abort(404);
        }

        return view('posts.show', compact('post'));
    }

Route::get('posts/{slug}', [PostController::class, 'show'])->name('posts.show');
Route::resource('posts', PostController::class)->except([
    'show'
]);
