Disable/enable queries: SOLVED (use "skip")

I've seen it mentioned elsewhere that enabled is in the works, and to use useQueries in the meantime. It doesn't seem like useQueries, even if you memoize the args object, actually works this way. It simply never updates when the dynamically excluded query is eventually added.

Code:

  const foo = useQuery(api.app.getFoo, { fooId })
  const foosArgs = useMemo(() => {
    if (!foo) {
      return {}
    }
    const args = {
      foo: {
        query: api.app.getFoos,
        args: { barId: foo?.barId },
      },
    }
    return args
  }, [foo])
  const result = useQueries(foosArgs)
  const foos = result?.foos
  // foos => undefined

  const foo = useQuery(api.app.getFoo, { fooId })
  const foosArgs = useMemo(() => {
    if (!foo) {
      return {}
    }
    const args = {
      foo: {
        query: api.app.getFoos,
        args: { barId: foo?.barId },
      },
    }
    return args
  }, [foo])
  const result = useQueries(foosArgs)
  const foos = result?.foos
  // foos => undefined

Man, your model keeps making issues non-blocking. I can just handle undefined args in the convex query, no need for useQueries. Good to go on this, enabled is just a nice to have for me. Like is this maybe even better then enabled? It might be better.

Hey @erquhart this is definitely one way of getting around the limitation, handling it on the server. A way to skip subscribing to the query from the client should be coming soon as well.

Hey, is there any development on this?

Yeah we could probably delete this old thread, now that "skip" has existed for a while?
