Can you add a flappy bird demo? I find that flappy bird demos for state-over-wire tech like LiveView and Blazor to be a great gauge for performance and latency. If there is the slightest delay or inconsistency in performance you will be able to tell immediately.
I can't tell if you're joking, but just in case you're serious... the only thing benchmarking flappy bird demos tells you is how fast your internet connection is.
I am preeminently qualified to beg people to judge frameworks on API surface and architecture because I have written all of the so-called hi-perf frame rate demos for StimulusReflex and one of the main reasons we took them down is because it is only a distraction from the incredible force for good these libraries actually are.
How's this for a demo: when you embrace the Rails + StimulusReflex + Turbolinks stack, you don't need to introduce React in 90% of the scenarios it's improperly used today. You end up with UIs that run faster, are smaller over the wire, drastically simpler and more fun to build and easier for newcomers to contribute to.
I'm surprised (and happy) that you added ts-liveview. I'm working on 1.0 moving to use primus.js instead of raw websocket for better (dis)connection handling, and trying to make the integration of s-js less noisy.
