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
  • Text compression services (gzip, brotli)

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 converter on the server and make sure the cwebp encoder tool is available as cwebp on the command line.
  • For creating AVIV image variants, install the AVIF converter on the server and make sure the encoder tool is available as avifenc 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.
  • For creating gzipped versions of merged CSS and JavaScript files you need to have the GNU Gzip command line utility installed (standard on any Linux system), globally available as gzip binary.
  • For creating Brotli compressed versions of merged CSS and JavaScript files you need to have the Brotli command line utility installed, globally available as brotli binary.
