Framework yang pernah dipakai

Kesalahan saya

  1. Gaya kode tidak konsisten
  2. Sering membuat class yang gendut (Contoh: Controller dengan 15 method didalamnya)
  3. Menggunakan pattern yang kurang sesuai

Belajar dari kesalahan

Pengalaman adalah guru terbaik

Perbaiki Kesalahan #1

2<?php
3
4// Good
5$result = $object instanceof Model
6    ? $object->name
7    : 'A default value';
8
9$name = $isFoo ? 'foo' : 'bar';
10
11// Bad
12$result = $object instanceof Model ?
13    $object->name :
14   'A default value';

9Route::get('', 'HomeController@index');
10Route::get('/open-source', 'OpenSourceController@index');

Perbaiki Kesalahan #2

Ketika kode mulai besar dan kompleks

mulai pecah menjadi beberapa kode kecil

Simpan Semua Models dalam folder Models

Gunakan Aturan 7 Standard REST action di Controller

Resource

  • Index
  • Show
  • Create
  • Store
  • Edit
  • Update
  • Destroy

API Resource

  • Index
  • Show
  • Create
  • Store
  • Edit
  • Update
  • Destroy

2php artisan make:controller ProductsController --resource
3php artisan make:controller ProductsController --api

Perbaiki Kesalahan #3

Jangan menggunakan pattern karena terlihat keren

namun dari masalah apa yang akan dipecahkan

Lebih baik menerapkan cara-cara yang lebih mudah dan sederhana

Gunakan Jobs

Kode yang berulang di controller dapat dipecah menjadi sebuah Job

1
2<?php // app/Jobs/CloseOrder.php
3
4namespace App\Jobs;
5
6use App\Models\Order;
7
8class CloseOrder
9{
10    protected $order;
11
12    public function __construct(Order $order, $delay)
13    {
14        $this->order = $order;
15        $this->delay($delay);
16    }
17
18    public function handle()
19    {
20        if ($this->order->paid_at) {
21            return;
22        }
23
24        DB::transaction(function() {
25          // ...
26        });
27    }
28}
29
1
2<?php
3
4use App\Jobs\CloseOrder;
5
6dispatch(new CloseOrder($order, $delay = 500));
7

Gunakan Query Object

Query filter untuk menampilkan list bisa sangat panjang

1
2<?php
3
4namespace App\Http\Controllers;
5
6use App\Models\Stock;
7
8class StocksController extends Controller
9{
10  public function index()
11  {
12    $keyword = request('search');
13
14    $stocks = Stock::query()
15      ->with('product', 'product.category', 'branch')
16      ->leftJoin('products', function ($join) {
17          $join->on('stocks.product_id', 'products.id');
18      })
19      ->leftJoin('branches', function ($join) {
20          $join->on('stocks.branch_id', 'branches.id');
21      })
22      ->when($keyword, function ($query) use($keyword) {
23          return $query
24            ->where('stock', 'like', "%{$keyword}%")
25            ->orWhere('product_name', 'ilike', "%{$keyword}%")
26            ->orWhere('branch_name', 'ilike', "%{$keyword}%");
27      })
28      ->selectRaw('stocks.*, products.name as product_name, branches.name as branch_name')
29      ->paginate(request('per_page'));
30
31    return response()->json(compact('stocks'));
32  }
33}
34

2<?php // app/Queries/SearchStocks.php
3
4namespace App\Queries;
5
6use App\Models\Stock;
7use Illuminate\Contracts\Pagination\Paginator;

9final class SearchStocks
10{
11  public static function get($perPage = 20): Paginator
12  {
13    $keyword = request('search');
14
15    return Stock::query()
16      ->with('product', 'product.category', 'branch')
17      ->leftJoin('products', function ($join) {
18          $join->on('stocks.product_id', 'products.id');
19      })
20      ->leftJoin('branches', function ($join) {
21          $join->on('stocks.branch_id', 'branches.id');
22      })
23      ->when($keyword, function ($query) use($keyword) {
24          return $query
25            ->where('stock', 'like', "%{$keyword}%")
26            ->orWhere('product_name', 'ilike', "%{$keyword}%")
27            ->orWhere('branch_name', 'ilike', "%{$keyword}%");
28      })
29      ->selectRaw('stocks.*, products.name as product_name, branches.name as branch_name')
30      ->paginate($perPage);
31  }
32}
