Hi petays,
Thank you for writing.
We will consider adding Typescript definitions in the future versions. At present, we are focused on building the User Interface components and adding the missing features to the existing components.
Is not it possible to use the Framework without Typescript? We have tutorials like that one https://www.htmlelements.com/docs/create-angular-and-react-applications-with-shared-web-components/ which shows how to use a Custom Element from our framework within Angular & React projects which use Typescript. As for Type checking, all properties in our UI Components are Typed(int, float, date, string, bool) with built-in type checking at run-time i.e invalid values are handled by the framework.
Best regards,
