How to set a Heartbeat Timeout in TypeScript

To set a Heartbeat Timeout, use ActivityOptions.heartbeatTimeout. If the Activity takes longer than that between heartbeats, the Activity is failed.

// Creating a proxy for the activity.
const { longRunningActivity } = proxyActivities<typeof activities>({
  // translates to 300000 ms
  scheduleToCloseTimeout: '5m',
  // translates to 30000 ms
  startToCloseTimeout: '30s',
  // equivalent to '10 seconds'
  heartbeatTimeout: 10000,
});
