Deduplicate connections to SSE with useEventSource regardless of the event

[na2hiro]

use-event-source has a feature to deduplicate SSE connections in order to lower the number of EventStreams a browser needs to hold. However, when event name is the only differences, it creates multiple identical EventStreams and then on client side it listens to different events.

Instead, we can create a single EventStream for the same URL and withCredentials flag, no matter what event is.

Example

Given code like these

  const pinged = !!useEventSource(`/events`, { event: "ping" });

  const users = useEventSource(`/events`, { event: "users" });

It creates identical event streams
