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deprecated in v11 and superseded by core API class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.
