You are implementing a long-polling mechanism in an Angular service and notice that the service continues to poll even after navigating away from the component that initiated the polling. How can you prevent this unnecessary network activity?

  • Implement a timer-based mechanism
  • Terminate the service manually
  • Use an if statement to check the component's status
  • Use takeUntil with a component's lifecycle event
To prevent unnecessary network activity, you can use takeUntil with a component's lifecycle event, which will automatically unsubscribe when the component is destroyed.
