Little helper package for when you want to create files and save them to TYPO3's File Abstraction Layer


FAL Filewriter is no TYPO3 extension and not available via TER. It can only be installed via composer:

composer require smichaelsen/fal-filewriter



You need to create a class that provides the content that will be saved in a file. It has to implement the \Smichaelsen\FalFilewriter\FileGeneratorInterface, which is fairly easy.


By default your TYPO3 installation will have a storage record with uid 1 pointing to the fileadmin, but of course you can configure your own storage records pointing to other folders or even to external services like AWS.

Load the storage object like this:

$storage = $this->objectManager->get(\TYPO3\CMS\Core\Resource\StorageRepository::class)->findByUid($fileStorageUid);


The \Smichaelsen\FalFilewriter\FileWriterService has one public method saveFile() which takes the following parameters:

  • $fileGenerator: Your file generator object implementing the FileGeneratorInterface.
  • $fileIdentifier: The file name which may include a relative path inside the $storage folder. The file extension may be omitted. Then it is read from the $fileGenerator (->getFileExtension()). If the file name starts with a path that doesn't exist it will be tried to create that path.
  • $storage: The ResourceStorage object to save the file in. See above ("Storage") for more information.

As return value you will receive a \TYPO3\CMS\Core\Resource\FileInterface object for the saved file.


/** @var \Smichaelsen\FalFilewriter\FileWriterService $fileWriterService */
/** @var \Smichaelsen\FalFilewriter\FileGeneratorInterface $fileGenerator */
/** @var \TYPO3\CMS\Core\Resource\ResourceStorage $storage */
$fileObject = $fileWriterService->saveFile($fileGenerator, 'folder/my-filename', $storage);
