## Handlers & Routes

Handlers have a predefined Handler ID. 
In addition, there can be several *static* subroutes used to differentiate between different handlers of the same ID.
A subroute on a client must match a subroute on the server. So routes cannot be used for dynamic routing, unlike HTTP.

 log.Println("Connected")

 // Subscribe to subject
 log.Printf("Subscribing to subject 'bucketevents'\n")
 natsConnection.Subscribe("bucketevents", func(msg *nats.Msg) {

  // Handle the message
  log.Printf("Received message '%s\n", string(msg.Data)+"'")
 })

 // Keep the connection alive
 runtime.Goexit()
}
```

```
go run nats.go
