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

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

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

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

Volt Functional

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

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

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

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

Wire Directives

<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
