This extension provides tools to render Web Components with TYPO3.
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>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\DataProviding\Traits\ContentObjectRendererTrait;
use Sinso\Webcomponents\Dto\ComponentRenderingData;
class MyContentElement implements ComponentInterface
{
use ContentObjectRendererTrait;
public function provide(ComponentRenderingData $componentRenderingData): WebcomponentRenderingData
{
$record = $componentRenderingData->getContentRecord();
$properties = [
'title' => $record['header'],
'greeting' => 'Hello World!',
];
$componentRenderingData->setTagName('my-web-component');
$componentRenderingData->setTagProperties($properties);
}
}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\Traits\Assert;
use Sinso\Webcomponents\DataProviding\Traits\ContentObjectRendererTrait;
use Sinso\Webcomponents\DataProviding\Traits\FileReferences;
use Sinso\Webcomponents\Dto\ComponentRenderingData;
use TYPO3\CMS\Core\Resource\FileReference;
class Image implements ComponentInterface
{
use Assert;
use ContentObjectRendererTrait;
use FileReferences;
public function provide(ComponentRenderingData $componentRenderingData): WebcomponentRenderingData
{
$record = $componentRenderingData->getContentRecord();
$image = $this->loadFileReference($record, 'image');
// rendering will stop here if no image is found
$this->assert($image instanceof FileReference, 'No image found for record ' . $record['uid']);
$componentRenderingData->setTagName('my-image');
$componentRenderingData->setTagProperties(['imageUrl' => $image->getPublicUrl()]);
}
