Hello there,
I am learning GraphQL concepts so I am totally beginner. I am learning GraphQL Subscriptions in ApolloServer now, and as it is given in the Docs that Subscriptions are not supported in V3. So, I started learning using apollo-server-express package. But the Docs Also says that PubSub Class is not recommended for Production. So, I don’t quite understand why it is not recommended. Also, There is no Proper documentation for Production Libraries recommended by Apollo or anyone else. I literally couldn’t found any resource for those production libraries. So, I would like to learn how to setup those libraries to use PubSub.
