Is this library maintained and secure?

[Susccy]

We want to extend the open source Form.io API with additional functionality for our project and need to create custom evaluation methods with formiojs. This library seems to be exactly what we're looking for, however last activity was 10 months ago and there hasn't been a full release yet.

So I'm wondering does Form.io officially recommend usage of this library or is it deprecated? In the latter case, is there an alternative to running custom formiojs evaluation methods in an isolated-vm sandbox?

We tried using this and it doesn't seem to work for the formiojs methods we intend to run (e.g. Formio.createForm) because the entire setTimeout functionality is disabled via the globalCode mock even though formiojs seems to heavily rely on it.
