# Integrating with Third-party Libraries

Custom extensions allow the use of third-party library code that can also be integrated as part of the native VDL 5.8 language.

A simple script tag with a `src` attribute can be used as in HTML to include the library. Code to use the library is then added to the `transform` and `createViewModel` callbacks depending on whether it needs to transform the DOM or make updates at runtime.
