optimism VS cubism

I see it the following way: - Wrap a form into a Turbo Frame. - Attach a Stimulus controller to the form. - Listen for change events and perform a form submission (requestSubmit()) whenever an input value changed. - Use a specific parameter to distinguish real submissions from preview ones (e.g., by toggling a hidden input field value in the form): in the controller, do not call #save if it's a preview request; only render a form in response with validation errors. - The most challenging part: since the HTML contents of the form would be replaced, we need restore the cursor position and any new input data. I think, using morphdom solves this issue; that's how (I believe) Stimulus Reflex and optimism library in particular work.

One of the more exciting aspects of Kredis is the tools that can be built on top of it — we can build our own simple functionality like the preference storage we created today, but other smart folks are building gems on top of Kredis to enable functionality like presence tracking for application resources or complex, multi-stage forms.
