# Breaking: #64059 - Rewritten Javascript Tree Components {#breaking-64059}

See [forge#64059](https://forge.typo3.org/issues/64059)

## Description {#description}

In the process of refactoring prototype/scripta.culo.us code and migrate these to an AMD module, the tree component and its
drag&drop parts have been migrated to a RequireJS / jQuery module.

The page tree filter functionality of the prototype tree, which is not used in the TYPO3 core, was removed from the
tree component.

The file `typo3/js/tree.js` has been removed, the replacement code, based on jQuery is located under
EXT:backend/Resources/Public/JavaScript/LegacyTree.js.

## Impact {#impact}

Any usages in third party extensions that include `js/tree.js` will fail, as the tree component has been removed.
Any extension using the filter part of the tree.js component will not work.

## Affected installations {#affected-installations}

Any installation with its own backend module using the tree component from the core.

## Migration {#migration}

Rewrite any needed logic for filtering, and include the RequireJS module like in e.g.
FileSystemNavigationFrameController.php, to use the tree component. If the old code is needed, the `tree.js` file
and prototype need to be included as part of the extension, not from the core.
