Livewire 3.6 Released

Laravel Livewire released v3.6 this week with new HTML directives for showing and hiding DOM elements and JavaScript actions.

#JavaScript Actions

Caleb Porzio added support for defining JavaScript actions "which are JavaScript functions that can be called from wire:click or $wire, to either run client side code only or to apply optimistic updates before triggering a server request."

Here's an example from Pull Request #9202:

<?php
use Livewire\Volt\Component;

new class extends Component {
    public function save()
    {
        // ...
    }
};
?>

<div>
    <button wire:click="doSomething">Do Something</button>
</div>

@script
<script>
    $js('doSomething', () => {
        console.log('doSomething');

        $wire.save()
    });
</script>
@endscript

You can also call JavaScript actions from PHP using the ->js() method:

$this->js('onPostSaved'); 

You can learn more about JavaScript actions in the Actions documentation.

#New HTML Directives

Josh Hanley contributed the wire:show and wire:text directives, and Caleb Porzio contributed wire:cloak and wire:transition directives.

The wire:show and wire:text directives are Livewire equivalents of Alpine's x-show and x-text. The wire:show directive, for example, toggles an element's visibility using CSS

<div>
    <button x-on:click="$wire.showModal = true">New Post</button>
 
    <div wire:show="showModal">
        <form wire:submit="save">
            <textarea wire:model="content"></textarea>
 
            <button type="submit">Save Post</button>
        </form>
    </div>
</div>

The wire:text directive dynamically updates an element's content, making it useful for building optimistic UIs:

<div>
    <button x-on:click="$wire.likes++; $wire.like()">❤️ Like</button>
 
    Likes: <span wire:text="likes"></span>
</div>

You can learn more about these new directives from Livewire's documentation:

• wire:show (docs)
• wire:text (docs)
• wire:transition (docs)
