Accessing node name e.g. in a function

General
1

To get a better glance, I use multiple function nodes for lets say JSON-attributes and go on with them.
In my specific use case, I pick some special attributes and send them to distinct MQTT-topics.
So far, so good, all my nodes look somehing like this:

// JSON parsen
parsed = JSON.parse(msg.payload);
msg.payload = parsed.vehicleStatus.evStatus.batteryStatus;
msg.topic = "batterySoC";
return msg;

what would make life a bit easier would be, if the mgs.topic could get its value from the name of the Node, so something like

msg.topic = NODE_NAME;

Because then I'd only have to name the nodes and the MQTT-topic and -message would be in msg as it should be?

see:

    }

try...

msg.topic = env.get("NR_NODE_NAME");

or

msg.topic = node.name;

... that is little easier to remember :wink:
