I built my own "reactive" stack a decade ago and just keep refining it. I wanted to de-couple template HTML from visual logic, and visual logic from business logic. So I model everything on components within components, they all bootstrap whatever DOM templates they need and inherit the same basic methods, and it's all tied together with an event model that handles long polling and push updates but, crucially, does not do anything in the basic HTML templates other than adding a couple attributes like "role='photo-button'" where you need them. Server updates cascade to each JS component which updates the things it thinks need to be updated at a given time. It's more hand-coded, but it's easier to read and a lot easier to micro-manage.
