@mjablecnik You can add a PR into this branch and I will merge from time to time to keep it updated. This PR is just to keep track of all combined changes.

Hi, thanks for your work

I have some Bootstrap components and types implemented in this repo. They may be useful for implementing some of the work being done in the bootstrap folder. In particular, there are some @JS() annotated classes like Modal with the corresponding separate interface for usage in non-web (server-side) environments. This is using a fork of package:deact. However, I believe it could be ported to jaspr or at least use/explore a similar API. You can view the implemented components in this web page and the code of the deployed page.

If there is anything I can help you with please let me know.
