node.js - Node-Red: Create server and share input -

i'm trying create new node node-red. udp listening socket shall established via config node , shall pass incoming messages dedicated nodes processing. basic have:

function udpserver(n) {     red.nodes.createnode(this, n);     this.addr = n.host;     this.port = n.port;      var node = this;      var socket = dgram.createsocket('udp4');      socket.on('listening', function () {         var address = socket.address();         loginfo('udp server listening on ' + address.address + ":" + address.port);     });      socket.on('message', function (message, remote) {         var bb = new bytebuffer.frombinary(message,1,0);         var coedata = decodecoe(bb);         if (coedata.type == 'digital') { //handle digital output             // pass digital handling node         }         else if (coedata.type == 'analogue'){ //handle analogue output             // pass analogue handling node         }     });           socket.on("error", function (err) {         logerror("socket error: " + err);         socket.close();              });      socket.bind({         address: node.addr,         port: node.port,         exclusive: true     });      node.on("close", function(done) {         socket.close();     }); } red.nodes.registertype("myservernode", udpserver); 

for processing node:

function processanalog(n) {     red.nodes.createnode(this, n);     var node = this;     this.serverconfig = red.nodes.getnode(this.server);      this.channel = n.channel;      // how server's message here?  } red.nodes.registertype("process-analogue-in", processanalog); 

i can't figure out how pass messages socket receives variable number of processing nodes, i.e. multiple processing nodes shall share on server instance.

==== edit more clarity =====

i want develop new set of nodes:

one server node:

• uses config-node create udp listening socket
• managing socket connection (close events, error etc)
• receives data packages 1 many channels of different data

one many processing nodes

• the processing nodes shall share same connection server node has established
• the processing nodes shall handle messages server emitting
• possibly node-red flow use many processing nodes there channels in server's data package

to quote node-red documentation on config-nodes:

a common use of config nodes represent shared connection remote system. in instance, config node may responsible creating connection , making available nodes use config node. in such cases, config node should handle close event disconnect when node stopped.

as far understood this, make connection available via this.serverconfig = red.nodes.getnode(this.server); cannot figure out how pass data, received connection, node using connection.

a node has no knowledge of nodes connected downstream.

the best can first node have 2 outputs , send digital 1 , analogue other.

you passing array node.send() function.

e.g.

//this sends output first output node.sent([msg,null]);  //this sends output second output node.send([null,msg]); 

nodes have receive messagess need add listener input

e.g.

node.on('input', function(msg) {    ... }); 

all of documented on node-red page

the other option if udpserver node config node need implement own listeners, best bet mqtt nodes in core examples of pooling connections
