How to retrieve the topic that triggered a subscription?

[hrougier]

Hi,

Having a subscription to multiple topics, is there a way to retrieve the topic that triggered the Subscription resolver in the filter option?

@Subscription(() => SomeType, {
  topics: ['someTopic', 'someOtherTopic'],
  filter: ({ info, topic }) => {
   // use the topic and graphql query info to filter on subscription?
   // or some way to inject the topic into the context?
  },
})
someSubscription(@Root() payload) {
  return payload
}

Thanks

put the topic in the payload when you publish to pubsub
