I'm polling a PLC via setInterval once connected and passing data over socketio to a vue application.

Is there a more appropriate method to polling the PLC? Or is this the best way for "live" responses for a web front end?

This is the way to go for now, see mathiask88/node-snap7#21

I use the same approach in my (feathers) backend which polls the PLC DBs and emits socket events whenever a value changes

I'll add a polling example to documentation when I get a few spare minutes if you like?
