how do I add arbitrary attributes to a tag? for example [:table {:foo "bar"}] does not seem to translate to <table foo="bar">

@sonnyto: I’d think React cleans them up

"If you pass properties to native HTML elements that do not exist in the HTML specification, React will not render them. If you want to use a custom attribute, you should prefix it with data-."

what’s the main idea of using reactions?

currently, we just derive data in the component ...

@grav: if you derive in components they're recomputed each render I believe

@martinklepsch: Ok, so it’s an optimization. I wonder if it’s worth the complexity

It is an optimization but I thought it also was a way of explicitly defining a signal graph. It seems to me to be a decomplecting thing, not a complecting thing. I don’t use the database and reactions for static data, but I absolutely use it if I’m changing my render for any reason, the parts that can mutate go in the database, and I use reactions to describe signals that resolve to values and drive the react render.

@sonnyto if you have to have an unsupported attribute, you can [span {:dangerouslySetInnerHTML {:__html "<scary foo=1></scary>"}}], but best to avoid them if possible

@timothypratley: lol data-* attribute is supported so I used that

ooOOOOooo nice!!!
