Pub/Sub with NATS Broker
Use the NATS broker for pub/sub.
In code
package main
import (
"log"
"go-micro.dev/v6"
"go-micro.dev/v6/broker"
bnats "go-micro.dev/v6/broker/nats"
)
func main() {
b := bnats.NewNatsBroker()
svc := micro.NewService("nats-pubsub", micro.Broker(b))
svc.Init()
// subscribe
_, _ = broker.Subscribe("events", func(e broker.Event) error {
log.Printf("received: %s", string(e.Message().Body))
return nil
})
// publish
_ = broker.Publish("events", &broker.Message{Body: []byte("hello")})
svc.Run()
}
Via environment
Run your service with env vars set:
MICRO_BROKER=nats MICRO_BROKER_ADDRESS=nats://127.0.0.1:4222 go run main.go
