Is there a message queue or do I need websockets?

Should I be implementing websockets for real-time communication? Or is there a built-in message queue?

Hey Hiro!

The Node.js SDK uses gRPC by default (more efficient than WebSockets for this use case). Messages are streamed bidirectionally.

For Unreal, it’s integrated into the engine’s async subsystems.

You don’t need to manage the connection manually, the SDK handles reconnection, backoff, etc.
