Laravel Livewire: Full-Stack Without the SPA Nightmare

Laravel Livewire: Full-Stack Without the SPA Nightmare

Forget React. Forget Vue. Laravel Livewire delivers dynamic user interfaces using server-side PHP and minimal JavaScript. Build full-stack applications without the complexity of modern SPAs.

The Problem with Traditional SPAs

Modern web development has become a nightmare:

• Complex JavaScript build systems
• API/frontend synchronization hell
• State management complexity
• SEO and performance issues
• Massive bundle sizes

Livewire eliminates this complexity entirely.

What is Laravel Livewire?

Livewire is a full-stack framework for Laravel that makes building dynamic interfaces as simple as writing vanilla PHP. No APIs, no JavaScript frameworks, no build tools.

Core Principles

• Server-side rendering: Components rendered on the server
• AJAX magic: Automatic DOM diffing and updating
• PHP-first: Write logic in PHP, not JavaScript
• Progressive enhancement: Works with or without JavaScript

Building a Real-Time Todo Application

1. Create the Livewire Component

php artisan make:livewire TodoList

<?php

namespace App\Http\Livewire;

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

class TodoList extends Component
{
    public $todos;
    public $newTodo = '';
    public $editingId = null;
    public $editingText = '';
    
    protected $listeners = ['todoAdded' => 'refreshTodos'];

    public function mount()
    {
        $this->refreshTodos();
    }

    public function refreshTodos()
    {
        $this->todos = Todo::orderBy('created_at', 'desc')->get();
    }

    public function addTodo()
    {
        $this->validate([
            'newTodo' => 'required|min:3|max:255'
        ]);

        Todo::create([
            'text' => $this->newTodo,
            'completed' => false
        ]);

        $this->newTodo = '';
        $this->refreshTodos();
        
        // Emit event for other components
        $this->emit('todoAdded');
        
        session()->flash('message', 'Todo added successfully!');
    }

    public function toggleComplete($todoId)
    {
        $todo = Todo::find($todoId);
        if ($todo) {
            $todo->update(['completed' => !$todo->completed]);
            $this->refreshTodos();
        }
    }

    public function startEditing($todoId, $text)
    {
        $this->editingId = $todoId;
        $this->editingText = $text;
    }

    public function saveEdit()
    {
        $this->validate([
            'editingText' => 'required|min:3|max:255'
        ]);

        $todo = Todo::find($this->editingId);
        if ($todo) {
            $todo->update(['text' => $this->editingText]);
        }

        $this->cancelEdit();
        $this->refreshTodos();
    }

    public function cancelEdit()
    {
        $this->editingId = null;
        $this->editingText = '';
    }

    public function deleteTodo($todoId)
    {
        Todo::find($todoId)?->delete();
        $this->refreshTodos();
    }

    public function render()
    {
        return view('livewire.todo-list');
    }
}

2. Create the Blade Template

resources/views/livewire/todo-list.blade.php

<div class="max-w-2xl mx-auto p-6">
    <div class="bg-white rounded-lg shadow-lg p-6">
        <h1 class="text-3xl font-bold text-gray-800 mb-6">Todo List</h1>
        
        @if (session()->has('message'))
            <div class="bg-green-100 border border-green-400 text-green-700 px-4 py-3 rounded mb-4">
                
            </div>
        @endif

        <!-- Add Todo Form -->
        <form wire:submit.prevent="addTodo" class="mb-6">
            <div class="flex gap-2">
                <input 
                    type="text" 
                    wire:model.defer="newTodo"
                    placeholder="Add a new todo..."
                    class="flex-1 px-4 py-2 border border-gray-300 rounded-lg focus:ring-2 focus:ring-blue-500 focus:border-transparent"
                >
                <button 
                    type="submit"
                    class="px-6 py-2 bg-blue-500 text-white rounded-lg hover:bg-blue-600 transition-colors"
                    wire:loading.attr="disabled"
                >
                    <span wire:loading.remove>Add</span>
                    <span wire:loading>Adding...</span>
                </button>
            </div>
            @error('newTodo') 
                <span class="text-red-500 text-sm mt-1 block"></span> 
            @enderror
        </form>

        <!-- Todo List -->
        <div class="space-y-2">
            @forelse($todos as $todo)
                <div class="flex items-center gap-3 p-3 border border-gray-200 rounded-lg hover:bg-gray-50 transition-colors">
                    <!-- Checkbox -->
                    <input 
                        type="checkbox" 
                        wire:click="toggleComplete()"
                        
                        class="w-5 h-5 text-blue-600 rounded"
                    >
                    
                    <!-- Todo Text -->
                    <div class="flex-1">
                        @if($editingId === $todo->id)
                            <div class="flex gap-2">
                                <input

                                    wire:model.defer="editingText"
                                    wire:keydown.enter="saveEdit"
                                    wire:keydown.escape="cancelEdit"
                                    class="flex-1 px-2 py-1 border border-gray-300 rounded"

                                >
                                    Save
                                </button>
                                <button

                                >
                                    Cancel
                                </button>
                            </div>
                        @else
                            <span 
                                class=""

                        @endif
                    </div>
                    
                    <!-- Actions -->
                    @if($editingId !== $todo->id)
                        <button 
                            wire:click="deleteTodo()"

                <div class="text-center py-8 text-gray-500">
                    No todos yet. Add one above!
                </div>
            @endforelse
        </div>
    </div>
</div>

3. Todo Model and Migration

php artisan make:model Todo -m

Migration:

<?php

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

return new class extends Migration
{
    public function up()
    {
        Schema::create('todos', function (Blueprint $table) {
            $table->id();
            $table->string('text');
            $table->boolean('completed')->default(false);
            $table->timestamps();
        });
    }

    public function down()
    {
        Schema::dropIfExists('todos');
    }
};

Model:

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class Todo extends Model
{
    protected $fillable = ['text', 'completed'];
    
    protected $casts = [
        'completed' => 'boolean'
    ];
}

Advanced Livewire Features

Real-Time Updates with Broadcasting

class TodoList extends Component
{
    protected $listeners = ['echo:todos,TodoUpdated' => 'refreshTodos'];
    
    public function addTodo()
    {
        // ... validation and creation
        
        // Broadcast to all connected clients
        broadcast(new TodoUpdated($todo));
        
        $this->refreshTodos();
    }
}

File Uploads

use Livewire\WithFileUploads;

class FileUploader extends Component
{
    use WithFileUploads;
    
    public $photo;
    
    public function save()
    {
        $this->validate([
            'photo' => 'image|max:1024', // 1MB Max
        ]);
        
        $path = $this->photo->store('photos');
        
        // Save to database
        auth()->user()->update(['avatar' => $path]);
        
        session()->flash('message', 'Photo uploaded successfully!');
    }
    
    public function render()
    {
        return view('livewire.file-uploader');
    }
}

<div>
    @if ($photo)
        <img src="" class="w-32 h-32 object-cover rounded">
    @endif
    
    <input type="file" wire:model="photo">
    
    @error('photo') <span class="error"></span> @enderror
    
    <button wire:click="save" wire:loading.attr="disabled">
        <span wire:loading.remove>Save Photo</span>
        <span wire:loading>Uploading...</span>
    </button>
</div>

Pagination

use Livewire\WithPagination;

class PostsList extends Component
{
    use WithPagination;
    
    public $search = '';
    
    public function updatingSearch()
    {
        $this->resetPage();
    }
    
    public function render()
    {
        return view('livewire.posts-list', [
            'posts' => Post::where('title', 'like', '%' . $this->search . '%')
                          ->paginate(10)
        ]);
    }
}

Performance Optimization

1. Defer Loading Heavy Components

class ExpensiveComponent extends Component
{
    public $readyToLoad = false;
    
    public function loadData()
    {
        $this->readyToLoad = true;
    }
    
    public function render()
    {
        return view('livewire.expensive-component', [
            'data' => $this->readyToLoad ? $this->getExpensiveData() : []
        ]);
    }
}

2. Optimize Network Requests

class OptimizedComponent extends Component
{
    // Only update when explicitly called
    public function hydrate()
    {
        // Runs on every request
    }
    
    // Lazy load properties
    public function getDataProperty()
    {
        return cache()->remember('expensive-data', 3600, function () {
            return $this->calculateExpensiveData();
        });
    }
}

Security Considerations

Input Validation

public function updatePost()
{
    $this->validate([
        'title' => 'required|max:255',
        'content' => 'required|min:10'
    ]);
    
    // Authorization
    $this->authorize('update', $this->post);
    
    $this->post->update($this->only(['title', 'content']));
}

Mass Assignment Protection

protected $fillable = ['title', 'content']; // In Livewire component

public function updatePost()
{
    $this->post->update($this->only($this->fillable));
}
