How do I stop a createHeartbeat loop after a status check is done?

[clyxudev]

I want a small heartbeat while a status check is running. What should stop the interval and how can I inspect the last beat?

Create it with createHeartbeat({ interval, onBeat }), call start() while the status check is active, then call stop() when the check finishes. stop() clears the interval and returns snapshot() with running, count, startedAt, lastBeatAt, and interval; listeners can use onBeat(handler) and keep the unsubscribe function.
