Which is feasible technology to develop office add-in in word?

Question

We've been relying on Angular for our system development, but now we're looking to create an Office add-in for Word using Angular. However, we've discovered that the Angular for Office add-in project has been archived as per below link.

https://github.com/OfficeDev/Word-Add-in-Angular2-StyleChecker

Here are our questions:

1. Can we continue to use Angular for our project, given our current needs and goals?
2. If not, are there other technologies or frameworks that you suggest could be better suited and more efficient for our system development?
3. We're also interested in knowing if there's a recommended technology with assured long-term support for Office add-in development.
