# Deprecation: #101799 - ExtensionManagementUtility::addPageTSConfig() {#deprecation-101799-1693397542}

See [forge#101799](https://forge.typo3.org/issues/101799)

## Description {#description}

The method `\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addPageTSConfig()`
has been marked as deprecated in TYPO3 v13 and will be removed with TYPO3 v14.

The global configuration option `$GLOBALS['TYPO3_CONF_VARS']['BE']['defaultPageTSconfig']`
has been marked as deprecated in TYPO3 v13, will be ignored and removed from instance configuration
files as silent upgrade with TYPO3 v14.

## Impact {#impact}

Setting default page TSconfig using `ExtensionManagementUtility::addPageTSConfig()`
in `ext_localconf.php` files has been superseded by
[Automatic inclusion of page TSconfig of extensions](https://docs.typo3.org/permalink/changelog:feature-96614) with
TYPO3 v12 already. The old way has been deprecated now, extensions should switch to
the new functionality by placing default page TSconfig in `Configuration/page.tsconfig`
files.

## Affected installations {#affected-installations}

Instances with extensions using `ExtensionManagementUtility::addPageTSConfig()`
or directly extending `$GLOBALS['TYPO3_CONF_VARS']['BE']['defaultPageTSconfig']`
are affected: Using `ExtensionManagementUtility::addPageTSConfig()` triggers a
deprecation level log message. The extension scanner will find usages of
`ExtensionManagementUtility::addPageTSConfig()` as strong match.

## Migration {#migration}

Add default page TSconfig to a `Configuration/page.tsconfig` file within an
extension and remove calls to `ExtensionManagementUtility::addPageTSConfig()`.
Placing default page TSconfig in `Configuration/page.tsconfig` files is
available since TYPO3 v12, extensions aiming for v12 and v13 compatibility can
simply switch over to the new way.
