Description

A third-party Laravel Livewire integration for Statamic.

It's as easy as it gets to get started with Livewire if using Statamic.

Installation

Pull in the Livewire package with composer

composer require jonassiewertsen/statamic-livewire

Manually including Livewire's frontend assets

By default, Livewire injects the JavaScript and CSS assets it needs into each page that includes a Livewire component. If you want more control over this behavior, you can manually include the assets on a page using the following Antlers tags or Blade directives:

<html>
    <head>
        <!-- If using Antlers -->
        {{ livewire:styles }}

        <!-- If using Blade -->
        @livewireStyles
    </head>
    <body>

        ...
        <!-- If using Antlers -->
        {{ livewire:scripts }}

        <!-- Blade -->
        @livewireScripts
    </body>
</html>

Manually bundling Livewire and Alpine

If you need to include some custom Alpine plugins, you need to manually bundle the Livewire and Alpine assets and disable the automatic injection by using the following Antlers tag or Blade directive. Do not forget to include the Livewire styles as well.

<html>
    <head>
        <!-- If using Antlers -->
        {{ livewire:styles }}

        <!-- If using Blade -->
        @livewireStyles
    </head>
    <body>

        ...
        <!-- If using Antlers -->
        {{ livewire:scriptConfig }}

        <!-- Blade -->
        @livewireScriptConfig
    </body>
</html>

Static caching

This addon adds an AssetsReplacer class to make Livewire compatible with half and full static caching. You may customize the replacers in the config of this addon:

'replacers' => [
    \Jonassiewertsen\Livewire\Replacers\AssetsReplacer::class,
],

If you are using full measure static caching and you're manually bundling Livewire and Alpine as per the instructions above, you need to make sure to only start Livewire once the CSRF token has been replaced.

if (window.livewireScriptConfig?.csrf === 'STATAMIC_CSRF_TOKEN') {
    document.addEventListener('statamic:nocache.replaced', () => Livewire.start());
} else {
    Livewire.start();
}

Upgrade

Make sure to read the Livewire upgrade guide, in case you're updating to Statamic Livewire 3, as there are breaking changes: https://livewire.laravel.com/docs/upgrading

General documentation

Livewire Docs

Include components

You can create Livewire components as described in the general documentation. To include your Livewire component:

<body>
    <!-- If using Antlers -->
    {{ livewire:your-component-name }}

    <!-- If using Blade -->
    <livewire:your-component-name />
</body>

if you want to include a component from a dynamic variable you can use the livewire:component tag:

<body>
    <!-- If using Antlers -->
    {{ livewire:component :name="variable" }}

    <!-- If using Blade -->
    <livewire:component name="$variable" />
</body>

@script and @assets

Antlers versions of @script and @assets are provided:

<body>
    {{ livewire:script }}

    {{ /livewire:script }}
</body>

<body>
    {{ livewire:assets }}

    {{ /livewire:assets }}
</body>

Blade or Antlers? Both!

If creating a Livewire component, you need to render a template file

namespace App\Http\Livewire;

use Livewire\Component;

class Counter extends Component
{
    public function render()
    {
        return view('livewire.counter');
    }
}

More Information: (https://livewire.laravel.com/docs/components)

Normally your template file would be a blade file, named counter.blade.php. Great, but what about Antlers? Rename your template to counter.antlers.html, use Antlers syntax and do whatever you like. No need to change anything inside your component Controller. How cool is that?

Passing Initial Parameters

You can pass data into a component by passing additional parameters

<!-- If using Antlers -->
{{ livewire:your-component-name :contact="contact" }}

<!-- If using Blade -->
<livewire:your-component-name :contact="$contact">

To intercept with those parameters, mount them and store the data as public properties.

use Livewire\Component;

class ShowContact extends Component
{
    public $name;
    public $email;

    public function mount($contact)
    {
        $this->name = $contact->name;
        $this->email = $contact->email;
    }

    ...
}

The Official Livewire documentation provides more information.

Keying Components

Livewire components are automatically keyed by default. If you want to manually key a component, you can use the key attribute.

<!-- If using Antlers -->
{{ contacts }}
    {{ livewire:your-component-name :key="id" }}
{{ /contacts }}

<!-- If using Blade -->
@foreach ($contacts as $contact)
    <livewire:your-component-name :key="$contact->id" />
@endforeach

The Official Livewire documentation provides more information.

Multi-Site

When using Livewire in a Multi-Site context, the current site gets lost between requests. There is a trait (\Jonassiewertsen\Livewire\RestoreCurrentSite) to solve that. Just include it in your component and use Site::current() as you normally do.

class ShowArticles extends Component
{
    use \Jonassiewertsen\Livewire\RestoreCurrentSite;

    protected function entries()
    {
        return Entry::query()
            ->where('collection', 'articles')
            ->where('site', Site::current())
            ->get();
    }

    public function render()
    {
        return view('livewire.blog-entries', $this->entries());
    }
}

Paginating Data

You can paginate results by using the WithPagination trait.

Blade

To use pagination with Blade, please use the Livewire\WithPagination namespace for your trait as described in the Livewire docs.

Antlers

Pagination with Antlers does work similar. Make sure to use the Jonassiewertsen\Livewire\WithPagination namespace for your trait if working with Antlers.

In your Livewire component view:

{{ entries }}
    ...
{{ /entries }}

{{ links }}

use Jonassiewertsen\Livewire\WithPagination;

class ShowArticles extends Component
{
    use WithPagination;

    protected function entries()
    {
        $entries = Entry::query()
            ->where('collection', 'articles')
            ->paginate(3);

        return $this->withPagination('entries', $entries);
    }

    public function render()
    {
        return view('livewire.blog-entries', $this->entries());
    }
}

EXPERIMENTAL: Statamic Support

As a little experiment, support for an Entry or EntryCollection has been added, so you can make an entry or a entry collection simply a public property and it just works.

Supported types: - Statamic\Entries\EntryCollection; - Statamic\Entries\Entry;

namespace App\Livewire;

use Livewire\Component;
use Statamic\Entries\EntryCollection;
use Statamic\Entries\Entry;

class Foo extends Component
{
    public EntryCollection $entries;
    public Entry $entry;

    // normal livewire stuff
}

To make it work, you need to enable that feature first.

  1. php artisan vendor:publish
  2. Select statamic-livewire in the list
  3. Enable synthesizers

Entangle: Sharing State Between Livewire And Alpine

In case you want to share state between Livewire and Alpine, there is a Blade directive called @entangle. To be usable with Antlers, we do provide a dedicated tag:

<!-- With Antlers -->
<div x-data="{ open: {{ livewire:entangle property='showDropdown' modifier='live' }} }">

<!-- With Blade -->
<div x-data="{ open: @entangle('showDropdown').live }">

It's worth mentioning that, since Livewire v3 now builds on top of Alpine, the @entangle directive is not documented anymore. Instead, it's possible to entangle the data via the $wire object.

<div x-data="{ open: $wire.entangle('showDropdown', true) }">

This: Accessing the Livewire component

You can access and perform actions on the Livewire component like this:


It's worth mentioning that, since Livewire v3 now builds on top of Alpine, the @this directive is not used widely anymore. Instead, it's possible to access and manipulate the state directly via JavaScript / the $wire object.


Lazy Components

Livewire allows you to lazy load components that would otherwise slow down the initial page load. For this you can simply pass lazy="true" as argument to your component tag.

<!-- With Antlers -->
{{ livewire:your-component-name :contact="contact" lazy="true" }}
