Deprecation: #92494 - Extbase EnvironmentService¶
The extbase class
TYPO3\CMS\Extbase\Service\EnvironmentService is an API
for TYPO3's legacy constant
TYPO3_MODE. That constant has been marked as
deprecated in v11 and superseded by core API class
TYPO3\CMS\Core\Http\ApplicationType, which relies on a PSR-7 request
to determine frontend or backend mode. The
EnvironmentService has now
been marked as deprecated as a logical follow-up to these works.
Using the class will trigger a PHP
@internal, some extensions
may still rely on it. The extension scanner will find usages.
