Get the list of all subscribers to a public graphql subscription

Question

I'm implementing a graphql server, it must have a public subscription for public updates. My question is, how would one get the subscriber count? Is there something I'm missing about graphql subscriptions? Are graphql endpoints even supposed to be freely available?

Answer 1

You will need to create a Publisher/Subscriber instance. Check out this example . From there you should be able to implement the counter. So each time you add a subscriber you can increment the count.
