Composer for TYPO3 Extensions


Show in app


This skill introduces usage of Composer for extensions and their integration into TYPO3 projects.


  • I know which fields to use in the composer.json of my extension, what they mean and how they work, so that I can create working, readable and helpful composer.json files.
  • I can use 3rd-party extensions and my own extensions in my site project via Composer.
  • I also know the benefits and drawbacks of using Composer and can advise my coworkers and clients when to use which approach.
  • In addition, I can build composer.json and ext_emconf.php files in such a way that their data is synchronized correctly.
  • Also, I know how to update the autoloader data for non-Composer installations.
