I've been taking a similar, but somewhat different approach to upgrading some old Knockout projects to mostly Vanilla JS+RxJS. Here's one example app: https://github.com/WorldMaker/compradprog/blob/main/main.tsx https://github.com/WorldMaker/compradprog/blob/main/main.tsx One of the obvious differences is that I'm still using TSX, but it is very different from React, it just looks a lot like React at first glance. Also, because I was doing it across at least a couple of projects, I started it from the beginning as its own small framework and have been trying to document it: https://github.com/WorldMaker/butterfloat/tree/main https://github.com/WorldMaker/butterfloat/tree/main It's still very much in early "prerelease" stages, but feedback is welcome.
