# RequireJS in the TYPO3 Backend {#requirejs}

Since TYPO3 v7 it is possible to use RequireJS in the backend.
A short explanation: RequireJS enables developers to have some kind of
dependency handling for JavaScript. The JavaScript is written as so-called
"Asynchronous Module Definition" (AMD).
Some libraries delivered with TYPO3 are written as modules.

## Credits {#credits}

The complete documentation about RequireJS was inspired by the
[blog post of Andreas Fernandez](https://scripting-base.de/blog/requirejs-backend.html).
