Subscription

createSubscription()

Subscribe/notify primitive used by every reactive handle.

• onFirstSubscribe attaches on first subscriber and cleans up on last.
• notify calls every subscriber; the first throw is rethrown after the loop.
• size is the subscriber count.

Examples

import { createSubscription } from 'seitu'

const { subscribe, notify, size } = createSubscription({
  onFirstSubscribe: () => {
    const id = setInterval(notify, 1000)
    return () => clearInterval(id)
  },
})
