node.js - Node-Redis psubscribe with custom messages -

i under impression using library:

https://github.com/mranney/node_redis

could this:

var redis = require('redis');  var pub = redis.createclient(); var sub = redis.createclient();  sub.psubscribe('channel');  sub.on('message channel', function(){});  pub.publish('channel','a message xyz'); 

the problem can't seem sub.on() receive specific custom message. entry point seems fired sub.on('message') or sub.on('pmessage'), how can sub.on('my custom message') invoked? hope makes sense.

this how node redis client works. reserves message , pmessage emit events notifying of subscribe , psubscribe events respectively.

but if want syntax have in code can define own message format , eventemitter, maybe:

var events = require('events'); var redis = require('redis'); var pub = redis.createclient(); var sub = redis.createclient();  var ee = new events.eventemitter();  ee.on('aweomseevent', function() {     console.log('party!'); });  sub.on('subscribe', function() {     var message = {         type: 'aweomseevent',         isawesome: true     };     pub.publish('mychannel', json.stringify(message)); });  sub.subscribe('mychannel'); sub.on('message', function(channel, message) {     var deserialized = json.parse(message);     if (deserialized.type) {         ee.emit(deserialized.type, deserialized);     } });
