Tahapan Implementasi & Walkthrough Kode

Berikut adalah langkah demi langkah teknis yang dapat Anda ikuti langsung pada codebase Anda:

Tahap 1: Penulisan Kode & Konfigurasi

        }

        //redirect to index
        return redirect()->route('posts.index')->with(['success' => 'Data Berhasil Diubah!']);
    }

     * destroy

        //delete image
        Storage::delete('public/posts/'. $post->image);

        //delete post
        $post->delete();

        //redirect to index
        return redirect()->route('posts.index')->with(['success' => 'Data Berhasil Dihapus!']);
    }
}

Tahap 2: Penulisan Kode & Konfigurasi

public function destroy($id): RedirectResponse
{

	//...
	
}

Tahap 3: Penulisan Kode & Konfigurasi

//get post by ID
$post = Post::findOrFail($id);

Tahap 4: Penulisan Kode & Konfigurasi

//delete image
Storage::delete('public/posts/'. $post->image);

Tahap 5: Penulisan Kode & Konfigurasi

//delete post
$post->delete();

Tahap 6: Penulisan Kode & Konfigurasi

//redirect to index
return redirect()->route('posts.index')->with(['success' => 'Data Berhasil Dihapus!']);
💡 Tips Rekayasa Perangkat Lunak (SiHubung Engineering Best Practice)

Selalu gunakan pendekatan deklaratif, validasi input seawal mungkin di boundary layer, dan lakukan logging terstruktur untuk memudahkan observability ketika sistem dijalankan di lingkungan cloud produksi.

Kesimpulan

Dengan mengikuti langkah-langkah terstruktur di atas, implementasi modul Anda akan jauh lebih rapi, aman dari bug umum, serta siap diskalakan ke lingkungan produksi.
