Introduction to Livewire

Livewire is a full-stack framework for Laravel that makes building dynamic interface simple, without leaving the comfort of Laravel. In this blog post, we’ll delve into the core features of Livewire and examine how it can enhance your Laravel applications.

Livewire Basics

Livewire allows you to build modern, dynamic, and reactive user interfaces using Laravel. It seamlessly integrates with Laravel’s ecosystem, allowing developers to write JavaScript like they write Blade and PHP.

Getting Started with Livewire

  composer require livewire/livewire
  php artisan livewire:make Counter

This will provide a new Counter component located in the App\Http\Livewire directory.

Example Component: Counter

  <?php

  namespace App\Http\Livewire;

  use Livewire\Component;

  class Counter extends Component
  {
      public $count = 0;

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

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

View for Counter Component

  <div>
      <h1>Counter: <?= $count ?></h1>
      <button wire:click="increment">+</button>
  </div>

Useful Livewire API

1. Actions

  <button wire:click="method">Click Me</button>

2. Properties

  <input type="text" wire:model="property">

3. Hooks

  public function updating{Property}()
  {
      // Do something before updating property
  }
  public function updated{Property}()
  {
      // Do something after updating property
  }

Building a Small Application with Livewire

Let’s create a simple to-do application using Livewire’s dynamic components.

ToDo Component

  <?php

  namespace App\Http\Livewire;

  use Livewire\Component;
  use App\Models\Todo;

  class Todos extends Component
  {
      public $todos;
      public $title;

      public function mount()
      {
          $this->todos = Todo::all();
      }

      public function addTodo()
      {
          Todo::create(['title' => $this->title]);
          $this->todos = Todo::all();
      }

      public function delete($id)
      {
          Todo::destroy($id);
          $this->todos = Todo::all();
      }

      public function render()
      {
          return view('livewire.todos');
      }
  }

View for ToDo Component

  <div>
      <div>
          <input type="text" wire:model="title">
          <button wire:click="addTodo">Add Todo</button>
      </div>
      <ul>
          @foreach($todos as $todo)
              <li>{{ $todo->title }} <button wire:click="delete({{ $todo->id }})">Delete</button></li>
          @endforeach
      </ul>
  </div>

By following this example, you can see the power and simplicity of using Livewire for creating dynamic applications with Laravel.
