Collection of building blocks and viewhelpers for TYPO3 projects by tollwerk

Domain objects


  • Custom Country model extending SJBR\StaticInfoTables\Domain\Model\Country (when the static_info_tables extension is installed)
  • UnsubmittableFormDefinition extending TYPO3\CMS\Form\Domain\Model\FormDefinition (Form Framework). Use for form definitions in combination with a custom hook to prevent advancing beyond the final form step (see class for hook example)


  • Custom CountryRepository providing the method findByIntlPhoneNumber() to find all countries using a country code starting with particular digits. Extends SJBR\StaticInfoTables\Domain\Repository\CountryRepository when the static_info_tables extension is installed.


  • DebuggableRepositoryTrait — add this to a repository and use the debugQuery() method for debugging SQL queries.
  • StoragePidsIgnoringRepositoryTrait — add this to a repository as a quick and easy way to make it ignore the storage PIDs.

Link handlers


  • Custom ImageService extending \TYPO3\CMS\Extbase\Service\ImageService adding format conversion capabilities
  • Image compression services (mozjpeg, SVGO)
  • Image converters (WebP)
  • Primitive LQIP service, creating SVGO previews of raster images

These services don't work out of the box and require particular software to be available on the server:

  • For optimizing JPEG images using the mozjpeg encoder, install the Mozilla JPEG Encoder Project and create a mozjpeg alias to jpegtran.
  • For creating WebP image variants, install the WebP on the server and make sure the cwebp encoder tool is available as cwebp on the command line.
  • For compressing SVG images on the fly, install the Node.js based SVGO tool and make sure it's available as svgo on the command line.
  • For creating SVG previews for images with Primitive, install the Go language and Primitive on your server and make sure primitive is available on the command line.
