Data fetching with GraphQL and ActionCable
summary
A concrete how-to for running GraphQL on Rails using the graphql-ruby gem, GraphiQL for introspection, and ActionCable WebSockets to push subscriptions and incremental responses. The presenter shows a working prototype that streams GraphQL patches using @defer/@stream and ActionCable (not yet in production), notes streaming multiple events over one channel, and flags the unresolved problem of end‑of‑stream signaling. Also covers persisted queries to save bandwidth and graphql-batch to fix N+1 queries. graphql-ruby GraphiQL ActionCable
