loopback2-component-pubsub
Loopback v2.x component that injects pubsub client into the global app object.
The main difference with Loopback /change-stream channels is that this implementation creates only two observers (after save and after delete) per model and then streams the changes to keep-alive registered connections. In contrast Loopback creates two same observers for each connection.
