+### **Prinsip _single responsibility_**
+
+Kelas dan metode seharusnya hanya memiliki satu tanggung jawab.
+
+Contoh buruk:
+
+```php
+public function getFullNameAttribute(): string
+{
+    if (auth()->user() && auth()->user()->hasRole('client') && auth()->user()->isVerified()) {
+        return 'Mr. ' . $this->first_name . ' ' . $this->middle_name . ' ' . $this->last_name;
+    } else {
+        return $this->first_name[0] . '. ' . $this->last_name;
+    }
+}
+```
+
+Contoh terbaik:
+
+```php
+public function getFullNameAttribute(): string
+{
+    return $this->isVerifiedClient() ? $this->getFullNameLong() : $this->getFullNameShort();
+}
+
+public function isVerifiedClient(): bool
+{
+    return auth()->user() && auth()->user()->hasRole('client') && auth()->user()->isVerified();
+}
+
+public function getFullNameLong(): string
+{
+    return 'Mr. ' . $this->first_name . ' ' . $this->middle_name . ' ' . $this->last_name;
+}
+
+public function getFullNameShort(): string
+{
+    return $this->first_name[0] . '. ' . $this->last_name;
+}
+```

+
+### **Model tebal, _controller_ tipis**
+
+Masukkan semua logika terkait DB ke model _eloquent_ atau ke dalam kelas repositori jika anda menggunakan _Query Builder_ atau kueri SQL mentah.
+
+Contoh buruk:
+
+```php
+public function index()
+{
+    $clients = Client::verified()
+        ->with(['orders' => function ($q) {
+            $q->where('created_at', '>', Carbon::today()->subWeek());
+        }])
+        ->get();
+
+    return view('index', ['clients' => $clients]);
+}
+```
+
+Contoh terbaik:
+
+```php
+public function index()
+{
+    return view('index', ['clients' => $this->client->getWithNewOrders()]);
+}
+
+class Client extends Model
+{
+    public function getWithNewOrders()
+    {
+        return $this->verified()
+            ->with(['orders' => function ($q) {
+                $q->where('created_at', '>', Carbon::today()->subWeek());
+            }])
+            ->get();
+    }
+}
+```
+
+[🔝 Kembali ke konten](#konten)
+
+### **Validasi**
+
+Pindahkan validasi dari _controller_ ke kelas _request_.
+
+Contoh buruk:
+
+```php
+public function store(Request $request)
+{
+    $request->validate([
+        'title' => 'required|unique:posts|max:255',
+        'body' => 'required',
+        'publish_at' => 'nullable|date',
+    ]);
+
+    ...
+}
+```
+
+Contoh terbaik:
+
+```php
+public function store(PostRequest $request)
+{
+    ...
+}
+
+class PostRequest extends Request
+{
+    public function rules()
+    {
+        return [
+            'title' => 'required|unique:posts|max:255',
+            'body' => 'required',
+            'publish_at' => 'nullable|date',
+        ];
+    }
+}
+```
+
+[🔝 Kembali ke konten](#konten)
+
+### **_Business logic_ harus di dalam kelas _services_**
+
+_Controller_ harus hanya memiliki satu tanggung jawab, jadi pindahkan _business logic_ dari _controller_ ke kelas _service_.
+
+Contoh buruk:
+
+```php
+public function store(Request $request)
+{
+    if ($request->hasFile('image')) {
+        $request->file('image')->move(public_path('images') . 'temp');
+    }
+
+    ...
+}
+```
+
+Contoh terbaik:
+
+```php
+public function store(Request $request)
+{
+    $this->articleService->handleUploadedImage($request->file('image'));
+
+    ...
+}
+
+class ArticleService
+{
+    public function handleUploadedImage($image)
+    {
+        if (!is_null($image)) {
+            $image->move(public_path('images') . 'temp');
+        }
+    }
+}
+```

+
+### **_Don't repeat yourself_ (DRY)**
+
+Gunakan kembali kode ketika anda bisa. [PSR](#prinsip-single-responsibility) membantu anda menghindari duplikasi. Juga, gunakan kembali _template blade_, _scope eloquent_, dll.
+
+Contoh buruk:
+
+```php
+public function getActive()
+{
+    return $this->where('verified', 1)->whereNotNull('deleted_at')->get();
+}
+
+public function getArticles()
+{
+    return $this->whereHas('user', function ($q) {
+            $q->where('verified', 1)->whereNotNull('deleted_at');
+        })->get();
+}
+```
+
+Contoh terbaik:
+
+```php
+public function scopeActive($q)
+{
+    return $q->where('verified', 1)->whereNotNull('deleted_at');
+}
+
+public function getActive()
+{
+    return $this->active()->get();
+}
+
+public function getArticles()
+{
+    return $this->whereHas('user', function ($q) {
+            $q->active();
+        })->get();
+}
+```
+
+[🔝 Kembali ke konten](#konten)
+
+### **Lebih memilih menggunakan _Eloquent_ daripada menggunakan _Query Builder_ dan query SQL mentah. Lebih memilih _collections_ daripada _array_**
+
+_Eloquent_ memungkinkan anda menulis kode yang dapat dibaca dan _maintainable_. Dan, _Eloquent_ memiliki _built-in tools_ yang bagus seperti _soft deletes_, _events_, _scopes_, dll.
+
+Contoh buruk:
+
+```sql
+SELECT *
+FROM `articles`
+WHERE EXISTS (SELECT *
+              FROM `users`
+              WHERE `articles`.`user_id` = `users`.`id`
+              AND EXISTS (SELECT *
+                          FROM `profiles`
+                          WHERE `profiles`.`user_id` = `users`.`id`)
+              AND `users`.`deleted_at` IS NULL)
+AND `verified` = '1'
+AND `active` = '1'
+ORDER BY `created_at` DESC
+```
+
+Contoh terbaik:
+
+```php
+Article::has('user.profile')->verified()->latest()->get();
+```
+
+[🔝 Kembali ke konten](#konten)
+
+### **_Mass assignment_**
+
+Contoh buruk:
+
+```php
+$article = new Article;
+$article->title = $request->title;
+$article->content = $request->content;
+$article->verified = $request->verified;
+
+// Add category to article
+$article->category_id = $category->id;
+$article->save();
+```
+
+Contoh terbaik:
+
+```php
+$category->article()->create($request->validated());
+```
+
+[🔝 Kembali ke konten](#konten)
+
+### **Jangan mengeksekusi kueri dalam _template blade_ dan gunakan _eager loading_ (masalah N + 1)**
+
+Contoh buruk (untuk 100 _user_, 101 kueri DB akan dieksekusi):
+
+```blade
+@foreach (User::all() as $user)
+    {{ $user->profile->name }}
+@endforeach
+```
+
+Contoh terbaik (untuk 100 _user_, 2 kueri DB akan dieksekusi):
+
+```php
+$users = User::with('profile')->get();
+
+@foreach ($users as $user)
+    {{ $user->profile->name }}
+@endforeach
+```
+
+[🔝 Kembali ke konten](#konten)
+
+### **Komentari kode anda, tetapi lebih baik _method_ dan nama variabel yang deskriptif daripada komentar**
+
+Contoh buruk:
+
+```php
+if (count((array) $builder->getQuery()->joins) > 0)
+```
+
+Contoh lebih baik:
+
+```php
+// Determine if there are any joins.
+if (count((array) $builder->getQuery()->joins) > 0)
+```
+
+Contoh terbaik:
+
+```php
+if ($this->hasJoins())
+```
+
+[🔝 Kembali ke konten](#konten)
+
+### **Jangan letakkan JS dan CSS di _template blade_ dan jangan letakkan HTML apa pun di kelas PHP**
+
+Contoh buruk:
+
+```javascript
+let article = `{{ json_encode($article) }}`;
+```
+
+Contoh lebih baik:
+
+```php
+<input id="article" type="hidden" value='@json($article)'>
+
+Atau
+
+<button class="js-fav-article" data-article='@json($article)'>{{ $article->name }}<button>
+```
+
+Dalam file javascript:
+
+```javascript
+let article = $('#article').val();
+```
+
+Cara terbaik adalah dengan menggunakan _package_ `PHP to JS` khusus untuk mentransfer data.
+
+[🔝 Kembali ke konten](#konten)
+
+### **Gunakan file _config_, _language_, dan konstanta daripada teks dalam kode**
+
+Contoh buruk:
+
+```php
+public function isNormal()
+{
+    return $article->type === 'normal';
+}
+
+return back()->with('message', 'Your article has been added!');
+```
+
+Contoh terbaik:
+
+```php
+public function isNormal()
+{
+    return $article->type === Article::TYPE_NORMAL;
+}
+
+return back()->with('message', __('app.article_added'));
+```
+
+[🔝 Kembali ke konten](#konten)
+
+### **Gunakan _tools_ standar Laravel yang diterima oleh komunitas**
+
+Selalu gunakan fungsi _built-in_ bawaan laravel dan _packages_ komunitas daripada menggunakan _packages_ dan _tools_ pihak ke-3. _Developer_ manapun yang akan bekerja dengan aplikasi anda di masa mendatang perlu mempelajari _tools_ baru. Dan juga, peluang untuk mendapatkan bantuan dari komunitas Laravel jauh lebih rendah saat anda menggunakan _packages_ atau _tools_ pihak ke-3. Jangan membuat klien Anda membayar untuk itu.

+### **Gunakan _IoC Container_ atau _facades_ daripada kelas baru**
+
+Sintaks Kelas baru membuat penggabungan yang sempit antar kelas dan memperumit proses pengujian. Gunakan _facades_ atau _IoC container_ sebagai gantinya.
+
+Contoh buruk:
+
+```php
+$user = new User;
+$user->create($request->validated());
+```
+
+Contoh terbaik:
+
+```php
+public function __construct(User $user)

+}
+
+...
+
+$this->user->create($request->validated());

+### **Jangan mendapatkan data dari file `.env` secara langsung**
+
+Alihkan data ke file konfigurasi sebagai gantinya dan kemudian gunakan fungsi `config ()` untuk menggunakan data dalam aplikasi.
+
+Contoh buruk:
+
+```php
+$apiKey = env('API_KEY');
+```
+
+Contoh terbaik:
+
+```php
+// config/api.php
+'key' => env('API_KEY'),
