🚀 Laravel Livewire

Revolution in Web Development with PHP Only - No JavaScript!

Build dynamic interactive interfaces like React or Vue, but using pure PHP!

🤔 What Exactly is Livewire?

Livewire is an open-source library for Laravel framework that allows you to build interactive and dynamic web interfaces using PHP only, without writing any JavaScript code.

🔍 How Livewire Works:

        // Livewire acts as a bridge between PHP and JavaScript 1. You write
        code in PHP (Controller + View) 2. Livewire automatically translates it
        to JavaScript 3. User interacts with the interface 4. Data goes to
        server and returns automatically 5. Interface updates without page
        refresh

✅ No JavaScript Required

🚀 How to Start? - Step by Step

Step 1: Installation

composer require livewire/livewire

Step 2: Include Livewire in Your Project

        <head> @livewireStyles </head> <body> // Your website
        content @livewireScripts </body>
      

Step 3: Create Your First Livewire Component

php artisan make:livewire Counter

Note: This command automatically creates two files:
• app/Http/Livewire/Counter.php (Class)
• resources/views/livewire/counter.blade.php (View)

💡 Practical Example: Interactive Counter

Part 1: Class (PHP)


<?php 
namespace App\Http\Livewire;

use Livewire\Component;

class Counter extends Component 
{ 
    public $count = 0;

    public function increment() 
    { 
        $this->count++; 
    } 

    public function decrement() 
    { 
        $this->count--; 
    } 

    public function resetCounter() 
    { 
        $this->count = 0; 
    }

    public function render() 
    { 
        return view('livewire.counter'); 
    } 
}
?>

Part 2: View (Blade)


            <div style="text-align: center; padding: 20px;">

                <h1 style="font-size: 3em; color: #ff2d20;">{{ $count }}</h1>

                <button wire:click="increment" style="background: #4CAF50; color: white; padding: 10px 20px; border: none; border-radius: 5px; margin: 5px;">➕ increment </button>

                <button wire:click="decrement" style="background: #f44336; color: white; padding: 10px 20px; border: none; border-radius: 5px; margin: 5px;">➖ decrement</button>

                <button wire:click="resetCounter" style="background: #ff9800; color: white; padding: 10px 20px; border: none; border-radius: 5px; margin: 5px;">🔄 Reset </button>

            </div>

Part 3: Usage in Any Page

<livewire:counter />

🔥 Advanced Example: Real-time Product Search

Class (PHP)

        <?php 
          namespace App\Http\Livewire; 

          use Livewire\Component; 
          use App\Models\Product; 

          class ProductSearch extends Component 
          { 
              public $search = ''; 
              public $products = []; 

              public function updatedSearch() 
              { 
                  $this->products = Product::where('name', 'like', '%'.$this->search.'%')
                      ->orWhere('description', 'like', '%'.$this->search.'%')
                      ->limit(10)
                      ->get(); 
              } 

              public function render() 
              { 
                  return view('livewire.product-search'); 
              } 
          } 
          ?>

View (Blade)


          <div> 
              <input type="text" wire:model="search" placeholder="Searching from products ..." style="width: 100%; padding: 10px; margin-bottom: 20px;"> 

              <div wire:loading>🔍 Searching for products...</div> 

              <div wire:loading.remove> 
                  @foreach($products as $product) 
                      <div class="product-item"> 
                          <h3>{{ $product->name }}</h3> 
                          <p>{{ $product->description }}</p> 
                          <span>السعر: ${{ $product->price }}</span> 
                      </div> 
                  @endforeach 

                  @if($search && $products->isEmpty()) 
                      <p> No products found"{{ $search }}"</p> 
                  @endif 
              </div> 
          </div>

💡 Golden Tips for Beginners

1. Start with Small Projects

Don't start with a big project, try counter, contact form, todo list first

2. Use wire:model.defer for Performance

For non-critical updates, use defer to postpone server requests

3. Learn Component Lifecycle

Understand methods like mount(), hydrate(), updated()

          public function mount() { // Executes once when component loads }
          public function updated($propertyName) { // Executes when any property
          updates }
