## Livewire Core
- Use the ___SINGLE_BACKTICK___search-docs___SINGLE_BACKTICK___ tool to find exact version specific documentation for how to write Livewire & Livewire tests.
- Use the ___SINGLE_BACKTICK___php artisan make:livewire [Posts\\CreatePost]___SINGLE_BACKTICK___ artisan command to create new components
- State should live on the server, with the UI reflecting it.
- All Livewire requests hit the Laravel backend, they're like regular HTTP requests. Always validate form data, and run authorization checks in Livewire actions.

## Livewire Best Practices
- Livewire components require a single root element.
- Use ___SINGLE_BACKTICK___wire:loading___SINGLE_BACKTICK___ and ___SINGLE_BACKTICK___wire:dirty___SINGLE_BACKTICK___ for delightful loading states.
- Add ___SINGLE_BACKTICK___wire:key___SINGLE_BACKTICK___ in loops:

    ___SINGLE_BACKTICK______SINGLE_BACKTICK______SINGLE_BACKTICK___blade
    @foreach ($items as $item)
        <div wire:key="item-{{ $item->id }}">
            {{ $item->name }}
        </div>
    @endforeach
    ___SINGLE_BACKTICK______SINGLE_BACKTICK______SINGLE_BACKTICK___

- Prefer lifecycle hooks like ___SINGLE_BACKTICK___mount()___SINGLE_BACKTICK___, ___SINGLE_BACKTICK___updatedFoo()___SINGLE_BACKTICK___ for initialization and reactive side effects:

<code-snippet name="Lifecycle hook examples" lang="php">
    public function mount(User $user) { $this->user = $user; }
    public function updatedSearch() { $this->resetPage(); }
</code-snippet>


## Testing Livewire

<code-snippet name="Example Livewire component test" lang="php">
    Livewire::test(Counter::class)
        ->assertSet('count', 0)
        ->call('increment')
        ->assertSet('count', 1)
        ->assertSee(1)
        ->assertStatus(200);
</code-snippet>


    <code-snippet name="Testing a Livewire component exists within a page" lang="php">
        $this->get('/posts/create')
        ->assertSeeLivewire(CreatePost::class);
    </code-snippet>
