I am finally trying to make the switch from Blaze to React and am having troubles to understand one simple concept I used all over the place with Blaze: template level subscriptions. I think I understand how subscriptions are done
withTracker, but none of the examples I have found so far show how to stop the subscription. I want to understand how the blaze pattern of subscribing to data in the
onCreated hook of a template and the automatic stopping of the subscription when destroying the template is done in react.
Any pointers welcome.
