Hi,
i am currently trying to create a custom node. In this custom node i need an instance from node-red-contrib-opcua. Especially from the server node there because i need the server object.
So i tried to "require" the whole server.js as a module inside my custom node. But this doesnt work because the module will try to register the server node which is already there.
Is there a better workaround for this? I need for example the initNewServer() function in this node. But it seemed to be encapsulated. Structure is:
module.exports = function (RED) {
...
OpcUaServerNode(n){
...
initNewServer(){
I am still a newbie with node.js and Node-RED so i don't know if there is a common solution for this. I know that i could create the server node from the "node-opcua" dependency myself, but it would be more logical for me to include the node-red-contrib-opcua as a Dependency because i work with more nodes from there inside my flows.
Thanks a lot
