Deprecation: #94791 - GeneralUtility::minifyJavaScript()

See forge#94791


The static method TYPO3\CMS\Core\Utility\GeneralUtility::minifyJavaScript() has been marked as deprecated.

Back in TYPO3 4.x times, the "jsmin" library was used to minify JavaScript, however as this became more flexible, a hook was introduced, and then "jsmin" was removed again. Since then, the hook to minify inline JavaScript is used in PageRenderer, and should rather be moved into the ResourceCompressor functionality, where it resides now.

The hook itself works exactly as before.


Calling the method will trigger a PHP E_USER_DEPRECATED error. Extension scanner will detect calls as strong match.

Affected Installations

TYPO3 installations with custom extensions calling this method, which is highly unlikely.

Custom extensions using this hook will still work as before without any changes.


As this method was used to only trigger a hook, it is recommended to use the PageRenderer and ResourceCompressor API instead, removing any direct calls to this method.

If still needed, extension authors can also copy the hook call execution to use the hook logic, which is not recommended though.
