As kevin pointed out Node-Red does have a OPC Server node.

There is a stripped down version of the server but the above gives you more features to expand later on and it has more examples for you to follow.

You could also use MQTT

I've used both methods, For what you are doing, its down to which road you think will be easier. I think MQTT may need a little bit more set up in ignition, Vs telling ignition what IP address to discover the OPC server. This is assuming your node red device is on the same network as ignition. If not, use MQTT.
