================================================ Deprecation: #92494 - Extbase EnvironmentService

See :issue:92494

Description

The extbase class :php:TYPO3\CMS\Extbase\Service\EnvironmentService is an API for TYPO3's legacy constant :php:TYPO3_MODE. That constant has been marked as deprecated in v11 and superseded by core API class :php:TYPO3\CMS\Core\Http\ApplicationType, which relies on a PSR-7 request to determine frontend or backend mode. The :php:EnvironmentService has now been marked as deprecated as a logical follow-up to these works.

Impact

Using the class will trigger a PHP :php:E_USER_DEPRECATED error.

Affected Installations

Even though :php:TYPO3\CMS\Extbase\Service\EnvironmentService is :php:@internal, some extensions may still rely on it. The extension scanner will find usages.

Migration

Instances with extensions using that class should either make their code agnostic to frontend or backend mode, or use :php:ApplicationType. Code examples can be found in the Changelog_ file.
