# Laravel Livewire

## Agent Workflow (MANDATORY)

Before ANY implementation, use `TeamCreate` to spawn 3 agents:

1. **fuse-ai-pilot:explore-codebase** - Check existing Livewire components
2. **fuse-ai-pilot:research-expert** - Verify Livewire 3 patterns via Context7
3. **mcp__context7__query-docs** - Check specific Livewire features

After implementation, run **fuse-ai-pilot:sniper** for validation.

## Overview

| Feature | Description |
|---------|-------------|
| **Components** | Reactive PHP classes with Blade views |
| **wire:model** | Two-way data binding |
| **Actions** | Call PHP methods from frontend |
| **Events** | Component communication |
| **Volt** | Single-file components |
| **Folio** | File-based routing |

---

## Critical Rules

1. **Always use wire:key** in loops
2. **Use wire:model.blur** for validation, not .live everywhere
3. **Debounce search inputs** with .debounce.300ms
4. **#[Locked]** for sensitive IDs
5. **authorize()** in destructive actions
6. **protected methods** for internal logic

## Decision Guide

### Component Type

```
Component choice?
├── Complex logic → Class-based component
├── Simple page → Volt functional API
├── Medium complexity → Volt class-based
├── Quick embed → @volt inline
└── File-based route → Folio + Volt
```

### Data Binding

```
Binding type?
├── Form fields → wire:model.blur
├── Search input → wire:model.live.debounce.300ms
├── Checkbox/toggle → wire:model.live
├── Select → wire:model
└── No sync → Local Alpine x-data
```

## Quick Reference

### Basic Component

```php
class Counter extends Component
{
    public int $count = 0;

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

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

### Volt Functional

```php
<?php
use function Livewire\Volt\{state};

state(['count' => 0]);

$increment = fn() => $this->count++;
?>

<button wire:click="increment">{{ $count }}</button>
```

### Wire Directives

```blade
<input wire:model.blur="email">
<input wire:model.live.debounce.300ms="search">
<button wire:click="save" wire:loading.attr="disabled">Save</button>
```

## Best Practices

### DO
- Use wire:key in @foreach loops
- Debounce search/filter inputs
- Use Form Objects for reusable logic
- Test with Livewire::test()
- #[Locked] for IDs, #[Computed] for derived data

### DON'T
- wire:model.live on every field
- Query in render() method
- Forget authorization in actions
- Skip wire:key in loops
- Store sensitive data in public properties

## Laravel 13 Notes

### Livewire 4 sur Laravel 13
Livewire 4 est la version compatible Laravel 13. Changements clés :

- **PHP 8.3 minimum** (était 8.2 sur Livewire 3)
- `wire:model.live` rate-limited par défaut (300ms debounce implicite)
- `#[Locked]`, `#[Computed]`, `#[On]` toujours supportés
- Volt et Folio : versions majeures alignées (Volt 2, Folio 2)
- **PreventRequestForgery** : routes `/livewire/update` gérées automatiquement, pas de config requise

### Migration depuis Livewire 3
- `wire:poll.5s` → toujours valide
- `$this->dispatch('event')` → toujours valide
- Form Objects (`#[\Livewire\Attributes\Validate]`) → API stable
