stop screen flicker from createResource refetch?

I'm refetching from a database every three seconds to display the most up to date values from a database without having to refresh the page.

  const [fetchedOnline, { refetch }] = createResource(
    () => [selectedZone(), selectedJob()],
    fetchOnline,
  )

  const timer = setInterval(() => {
    refetch()
  }, 3000)

  onCleanup(() => clearInterval(timer))

  const [fetchedOnline, { refetch }] = createResource(
    () => [selectedZone(), selectedJob()],
    fetchOnline,
  )

  const timer = setInterval(() => {
    refetch()
  }, 3000)

  onCleanup(() => clearInterval(timer))

Every time it updates, every three seconds, my screen flickers and shows some fallbacks from Shows for a brief second. I'd like for it to just show the old values until it gets the new ones... I'm playing with fetchedOnline.ready, fetchedOnline.loading, etc but not having any luck

SolidJS

Solid is a purely reactive library. It was designed from the ground up with a reactive core. It's influenced by reactive principles developed by previous libraries.

fancy Im going to try that Thanks. I used startTransition instead. I also think using refetch() instead of refetch had something to do with it well still having issues but working through it When I refresh the page it gives me this error: Uncaught (in promise) Error: Hydration Mismatch. Unable to find DOM nodes for hydration key: s00-1-0-0 Which was fixed by changing astro's client:load to client:only='solid-js'

I remember I had that kind of issues unless I used .latest Try to use fetchedOnline.latest in your JSX ?

As of 1.4.0, data.latest will return the last returned value and won't trigger Suspense and transitions; if no value has been returned yet, data.latest acts the same as data(). This can be useful if you want to show the out-of-date data while the new data is loading. https://www.solidjs.com/docs/latest/api#createresource

I asked this last week in solid-start, using .latest was the answer.
