What about support for data-* attributes?

I noticed I can add data-* attributes to the virtual dom and they work as expected both with React and Inferno. I’m curious about why this doesn’t work with Preact. Is that on purpose. What would be the reason for that? I just get an empty dataset with Preact.

for some deal types, will render over a thousand separate fields with components attached to them such as autocomplete, sliders and datepickers

the fast vdom libs have very low overhead [1]. most of the slowdown will be from the fact that you have a huge DOM for the browser to render rather than a huge backing vtree. “over one thousand” is peanuts 😃

A lot of the complexity and size in datepickers comes from those edge cases as @leeoniya pointed out. If you can skip them, skip them. The Canadian VS US dates you can probably do as a display mechanism if you’re using VDOM (data doesn’t have to be displayed in the same format as it is held/edited). I agree the numbers you’re looking at actually aren’t that bad, and Code Splitting seems like an easy bit of low-hanging fruit.
