Installation

You can install DCE with or without composer.

Important

When upgrading an existing installation, follow the DCE upgrading guide.

Note

If your project uses an older TYPO3 version, install an older, compatible DCE version instead. Check the available versions and their TYPO3 requirements on Packagist or in the TYPO3 Extension Repository.

Requirements

TYPO3 14.3 or newer within the TYPO3 14 release line
PHP 8.2
PHP extensions DOM and JSON

With composer

Require DCE on the command line:

$ composer req t3/dce:"^4.0"

Composer installs and activates DCE automatically. Afterwards, set up the extensions and apply the required database schema changes:

$ vendor/bin/typo3 extension:setup

Without composer

You can also fetch DCE from TER and install it without Composer. Import and activate the extension through System > Extensions.

Tip

Manual activation in System > Extensions is only required for installations without Composer.

DCE provides no further options here.
