README

This extension provides tools to render Web Components with TYPO3.

TypoScript based rendering

tt_content.tx_myext_mycontentelement = WEBCOMPONENT
tt_content.tx_myext_mycontentelement {
  tagName = my-web-component
  properties {
    title.data = header
    greeting = Hello World!
  }
}

Generates the output:

<my-web-component
    title="This is the title from the content element record"
    greeting="Hello World!"
></my-web-component>

Component class based rendering

You can populate the web component with PHP:

tt_content.tx_myext_mycontentelement = WEBCOMPONENT
tt_content.tx_myext_mycontentelement.component = Acme\MyExt\Components\MyContentElement

<?php

namespace Acme\MyExt\Components;

use Sinso\Webcomponents\DataProviding\ComponentInterface;
use Sinso\Webcomponents\Dto\ComponentRenderingData;
use Sinso\Webcomponents\Dto\InputData;

class MyContentElement implements ComponentInterface
{
    public function provide(InputData $inputData): ComponentRenderingData
    {
        $record = $inputData->record;
        $properties = [
            'title' => $record['header'],
            'greeting' => 'Hello World!',
        ];

        return (new ComponentRenderingData())
            ->withTagProperties($properties)
            ->withTagName('my-web-component');
    }
}

Abort rendering

The component classes can use the \Sinso\Webcomponents\DataProviding\Traits\Assert trait to abort rendering, for example if the record is not available:

<?php

namespace Acme\MyExt\Components;

use Sinso\Webcomponents\DataProviding\ComponentInterface;
use Sinso\Webcomponents\DataProviding\Helpers\FileReferencesHelper;
use Sinso\Webcomponents\DataProviding\Traits\Assert;
use Sinso\Webcomponents\Dto\ComponentRenderingData;
use Sinso\Webcomponents\Dto\InputData;
use TYPO3\CMS\Core\Resource\FileReference;

class Image implements ComponentInterface
{
    use Assert;

    public function __construct(
        private readonly FileReferencesHelper $fileReferencesHelper,
    ) {}

    public function provide(InputData $inputData): ComponentRenderingData
    {
        $record = $inputData->record;
        $image = $this->fileReferencesHelper->loadFileReference($record, 'image');

        // rendering will stop here if no image is found
        $this->assert($image instanceof FileReference, 'No image found for record ' . $record['uid']);

        return (new ComponentRenderingData())
            ->withTagProperty('imageUrl', $image->getPublicUrl())
            ->withTagName('my-image');
    }
}
