Pubsub Package Recommendations?

I use ApolloGraphQL for my live data subscriptions, with graphql-postgres-subscriptions as the pubsub. I see that graphql-postgres-subscriptions is 5 years old. What’s a good current pubsub to use?

Update:

Has anyone used one or more of these?

  • graphql-ws
  • PostGraphile
  • graphql-subscriptions
  • AWS AppSync
  • Pusher

Update: graphql-ws appears to be a drop-in replacement for graphql-postgres-subscriptions.
