react-rx@7.1.0

Minor Changes

• #690 f7527b8 Thanks @stipsan! - Add createObservableCache, a keyed cache of shared observables for request-like sources. Every
  caller of a key gets the same observable, which is what lets them share one request — and, since
  useObservablePromise caches its promise per observable identity, one settled promise. A sibling or
  a remount then renders the loaded value instead of suspending again, where an observable built per
  component (useMemo(() => fetchUser(id), [id])) makes every consumer fetch and suspend on its own.

  const users = createObservableCache(fetchUser, {ttl: USER_TTL})
  // const promise = useObservablePromise(users(id), {ttl: USER_TTL})

  Keys are plain strings. A key is released ttl after its last subscriber leaves — the same ttl an
  abandoned request keeps running for, and the window an entry nothing ever subscribed to gets.
  A request that produces no value at all is a failure, and failures are never cached (EmptyError,
  as in firstValueFrom). The cached observable ends at the first value and then stays open, so take
  it with first() / firstValueFrom rather than an operator that waits for completion, and expect
  one value per key — anything emitted or thrown after the result is truncated rather than pushed at
  subscribers who already settled. clear() forgets every key at once. See the
  reference for how this ttl nests with the
  hook's, and for choosing one that does not keep a Node process alive.
