Step 1: Set Up Laravel Project


Installing a fresh new laravel application, so head over to the terminal, type the command, and create a new laravel app.


```php
composer create-project --prefer-dist laravel/laravel cart
```

Step 2: Set Up Database Details in ENV


Now, you have to connect the laravel app to the database, hence open the .env configuration file and add the database credentials as suggested below.

.env
```php
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=database_name
DB_USERNAME=database_user_name
DB_PASSWORD=database_password

```
Step 3: Setup laravelshoppingcart package 
```html
composer require "darryldecode/cart"
```
Open config/app.php and add this line to your Service Providers Array.

```html
Darryldecode\Cart\CartServiceProvider::class
```
Open config/app.php and add this line to your Aliases

```html
'Cart' => Darryldecode\Cart\Facades\CartFacade::class
```

Optional configuration file (useful if you plan to have full control)

```html
php artisan vendor:publish --provider="Darryldecode\Cart\CartServiceProvider" --tag="config"
```
Install Livewire 
```html
composer require livewire/livewire
```
Include the JavaScript (on every page that will be using Livewire).
```html
...
  @livewireStyles
</head>
<body>
  ...

  @livewireScripts
</body>

```
Create Product Model with Migration
```html
php artisan make:model Product -m
```
product migration file
```php
<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreateProductsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('products', function (Blueprint $table) {
            $table->id();
            $table->string('name');
            $table->double('price');
            $table->text('description');
            $table->string('image');
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('products');
    }
}


```
product model file
```php
<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Product extends Model
{
    use HasFactory;
    protected $fillable = [
        'name',
        'price',
        'image',
        'description',
    ];
}

```
Create Product Seeder

```html
php artisan make:seeder ProductSeeder
```
Now add dummy data in seeder
```php
<?php

namespace Database\Seeders;

use App\Models\Product;
use Illuminate\Database\Seeder;

class ProductSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        Product::create([
            'name' => 'Watch',
            'price' => 250,
            'description' => 'Good watch',
            'image' => 'https://images.unsplash.com/photo-1523275335684-37898b6baf30?ixid=MnwxMjA3fDB8MHxwaG90by1wYWdlfHx8fGVufDB8fHx8&ixlib=rb-1.2.1&auto=format&fit=crop&w=989&q=80'
        ]);
        Product::create([
            'name' => 'Bag',
            'price' => 350,
            'description' => 'Good Bag',
            'image' => 'https://images.unsplash.com/photo-1491637639811-60e2756cc1c7?ixlib=rb-1.2.1&ixid=MnwxMjA3fDB8MHxwaG90by1wYWdlfHx8fGVufDB8fHx8&auto=format&fit=crop&w=669&q=80'
        ]);
        Product::create([
            'name' => 'perfume',
            'price' => 100,
            'description' => 'Good perfume',
            'image' => 'https://images.unsplash.com/photo-1528740561666-dc2479dc08ab?ixid=MnwxMjA3fDB8MHxwaG90by1wYWdlfHx8fGVufDB8fHx8&ixlib=rb-1.2.1&auto=format&fit=crop&w=1868&q=80'
        ]);
    }
}

```
Now create controller and routes

```html
php artisan make:controller ProductController
```
Create Routes in web.php
```php
<?php

use App\Http\Controllers\CartController;
use App\Http\Controllers\ProductController;
use Illuminate\Support\Facades\Route;

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

Route::get('/', [ProductController::class, 'productList'])->name('products.list');
Route::get('cart', [ProductController::class, 'cartList'])->name('cart.list');
Route::post('cart', [ProductController::class, 'addToCart'])->name('cart.store');

```
Add Code Logic In Controller
app/Http/Controllers/ProductController.php

```php
<?php

namespace App\Http\Controllers;

use App\Models\Product;
use Illuminate\Http\Request;

class ProductController extends Controller
{
    public function productList()
    {
        $products = Product::all();

        return view('products', compact('products'));
    }

    public function cartList()
    {
        return view('cart');
    }

    public function addToCart(Request $request)
    {
        \Cart::add([
            'id' => $request->id,
            'name' => $request->name,
            'price' => $request->price,
            'quantity' => $request->quantity,
            'attributes' => array(
                'image' => $request->image,
            )
        ]);
        session()->flash('success', 'Product is Added to Cart Successfully !');

        return redirect()->route('cart.list');
    }
}

```
Create View Files
