use Illuminate\Http\Request;
use Intervention\Image\Facades\Image;
use Illuminate\Support\Facades\DB;
class PostController extends Controller
{
    public function __construct()
    {
        $this->middleware('auth');
    }

    public function index()

        return view('posts.create');
    }

    public function store()
    {
        $data = request()->validate([
            'title' => ['required', 'string'],
            'image' => ['required', 'image'],

        $image = Image::make(public_path("/storage/{$imagePath}"))->fit(1200, 1200);
        $image->save();


        auth()->user()->posts()->create([
            'title' => $data['title'],
            'descriptionpost' => $data['descriptionpost'],
            'price' => $data['price'],
            'image' => $imagePath
        ]);

        return redirect()->route('profile.show', ['user' => auth()->user() ]);
    }

    public function show(Post $post)
    {
        return view('posts.show', compact('post'));
    }
}

route

Route::get('/welcome', 'PostController@index')->name('posts.index');

but i have this error :

Undefined variable: posts (View: /home/savinov/annonces/resources/views/welcome.blade.php)

dont understand why its undefined variable if i define him in controller, someone can helping to me if its possible?

try dd($posts) in your controller to see what you're getting. You can also just pass it in as return view('welcome', $posts); seeing as you're only passing in one variable — party-ring
@DenKot What doesn't work? Can you be more specific? He asked you to do more than 1 thing. What's dd($posts) returning to you? — César Escudero

You try like below options

option 1

public function index()
{
   $posts = DB::table('posts')->orderBy('created_at', 'DESC')->paginate(10);
   return view('welcome', ['posts' => $posts]);
}

option2

public function index()
{
    $posts = Post::orderBy('created_at', 'DESC')->paginate(10);
    return view('welcome',compact('posts'));
     or 
   return view('welcome', ['posts' => $posts]);
}
