# Feature: #101807 - Automatic inclusion of user TSconfig of extensions {#feature-101807-1693473782}

See [forge#101807](https://forge.typo3.org/issues/101807)

## Description {#description}

Extension authors can now put a file named
`Configuration/user.tsconfig` in their extension folder.

This file is then recognized to load the contents as global user TSconfig
for the whole TYPO3 installation during build-time. This is
more performant than the existing solution using
`ExtensionManagementUtility::addUserTSConfig()` in
`ext_localconf.php`, which is added to
`$TYPO3_CONF_VARS[SYS][defaultUserTSconfig]` during runtime.

## Impact {#impact}

When a file is created, the user TSconfig is loaded automatically without a
custom registration, cached within the Core caches, and more
performant than the existing registration format. The old registration
format has been marked as deprecated, see
[Deprecated ExtensionManagementUtility::addUserTSConfig()](https://docs.typo3.org/permalink/changelog:deprecation-101807-1693474000)
for more details.
