Buat Teknologi untuk Project Marketplace UMKM

Buat Latihan project Laravel marketplace minimal, siap dijalankan di XAMPP, dan saya sertakan semua file penting yang kamu butuh untuk menjalankan MVP (auth, produk, kategori, cart session, checkout sederhana, admin CRUD, seeder, storage link, dan instruksi).

Di bawah ini saya paste file-by-file yang perlu kamu buat/masukkan ke project (salin-tempel). Ikuti urutan supaya lebih rapi.

Asumsi: kamu pakai Laravel 10+, PHP ≥ 8.1, MySQL via XAMPP, project diletakkan di C:\xampp\htdocs\marketplace (Windows) atau /opt/lampp/htdocs/marketplace (Linux).
Jika mau, setelah ini saya juga bisa rapikan jadi checklist file yang bisa kamu copy-paste satu per satu.

1) FILE: .env.example

Salin ke .env lalu sesuaikan.

APP_NAME=Marketplace
APP_ENV=local
APP_KEY=
APP_DEBUG=true
APP_URL=http://localhost:8000

LOG_CHANNEL=stack

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=marketplace_db
DB_USERNAME=root
DB_PASSWORD=

FILESYSTEM_DRIVER=public

2) README singkat (README.md)

# Marketplace (Laravel) - Minimal MVP

Requirements:
- PHP 8.1+, Composer, Node.js (optional for assets)
- XAMPP (Apache + MySQL)

Setup:
1. letakkan folder project di htdocs
2. copy .env.example -> .env, set DB
3. run: composer install
4. run: php artisan key:generate
5. run: php artisan migrate --seed

        if(auth()->check() && auth()->user()->is_admin) return $next($request);
        abort(403,'Unauthorized');
    }
}

Daftarkan di app/Http/Kernel.php pada $routeMiddleware:

'is_admin' => \App\Http\Middleware\IsAdmin::class,

---

7) ROUTES (routes/web.php)

<?php
use Illuminate\Support\Facades\Route;

Route::prefix('admin')->middleware(['auth','is_admin'])->group(function(){
    Route::resource('products', ProductAdminController::class, ['as'=>'admin']);
});

require __DIR__.'/auth.php';

g) Admin views: resources/views/admin/products/*

(Admin index/create/edit — saya sudah sediakan contoh sebelumnya in the earlier message; paste them into respective files.)

---

9) SEEDER (database/seeders/SampleSeeder.php)

<?php
namespace Database\Seeders;
use Illuminate\Database\Seeder;
use Illuminate\Support\Str;
use App\Models\Category;
use App\Models\Product;
use App\Models\User;

class SampleSeeder extends Seeder {
    public function run(){
        // Admin user (password: password123)
        User::create([
            'name'=>'Admin',
            'email'=>'admin@example.com',
            'password'=>bcrypt('password123'),
            'is_admin'=>true
        ]);
        User::create([
            'name'=>'User',
            'email'=>'user@example.com',
            'password'=>bcrypt('password123'),
            'is_admin'=>false
        ]);

        $c1 = Category::create(['name'=>'Elektronik','slug'=>Str::slug('Elektronik')]);
        $c2 = Category::create(['name'=>'Fashion','slug'=>Str::slug('Fashion')]);

        Product::create(['name'=>'Headphone ABC','slug'=>'headphone-abc','description'=>'Headphone berkualitas','price'=>250000,'stock'=>10,'category_id'=>$c1->id]);
        Product::create(['name'=>'Kaos Polos','slug'=>'kaos-polos','description'=>'Kaos cotton 100%','price'=>50000,'stock'=>50,'category_id'=>$c2->id]);
    }
}

Update DatabaseSeeder.php agar memanggil SampleSeeder.

10) Perintah penting setelah menaruh file

Jalankan di terminal project:

composer install
cp .env.example .env
php artisan key:generate
php artisan migrate --seed
php artisan storage:link
php artisan serve --port=8000

Atau jika di XAMPP, akses http://localhost/marketplace/public (jika meletakkan di htdocs tanpa virtualhost).

Akun admin: admin@example.com / password123

11) Opsi fitur tambahan (opsional, nanti bila ingin dikembangkan)

• Integrasi payment gateway (Midtrans / Xendit / Stripe).

• Upload product gallery (multiple images).

• Seller accounts / multi-vendor (setiap UMKM punya dashboard sendiri).

• Rating & review, pencarian lanjutan, filter berdasarkan kategori & harga.

• Tema (themes folder + settings table untuk kustomisasi warna/logo via admin).
