Logger creation error

[wildart]

I'm trying to create logger by running following code (node 0.10.17)

var co = require('cocaine')
var Logger = co.Service('logging')
L = new Logger(argv.app)
L.info("test")

it generates an error:

/home/test/test/node_modules/cocaine/lib/services/logging.js:32
    this.verbosity()
         ^
TypeError: Object #<EventEmitter> has no method 'verbosity'

Ok, now. I clearly see that the right examples are missing. They are to be added some days this week.

Right away you can use services in a way like this: https://github.com/cocaine/cocaine-framework-nodejs/tree/development#make-use-of-cocaine-services

This one proved itself to be working:

I changed program as you recommended:

#!/usr/bin/node

var co = require('cocaine')
    , argv = require('optimist').argv
    , mp = require('msgpack')

var W, L

co.getServices(['logging'],function(Logger){

    L = new Logger(argv.app)
    W = new co.Worker(argv)

    W.on('test',function(stream){
        var msg
        L.info("Got request")
        stream.on('data',function(data){
            msg = data
            console.info('received:' + msg)
        })

        stream.on('end',function(){
            stream.write(mp.pack('respond:' + msg))
            stream.end()
        })
    })

    W.on('_terminate',function(){
        L.info('bridge terminated')
    })
    W.connect()
});

but still have an error during logger initialization:

/opt/cocaine/spool/test/node_modules/cocaine/node_modules/q/q.js:126
                    throw e;
                          ^

    at process._tickCallback (node.js:415:13)

And it is a logger initialization call again. Any clues?

Hi, I have a problem with logger.
I'm trying to add logger to my app (worker):

var cocaine = require('cocaine');
var cli = new cocaine.Client(); // ["localhost", 10053]
var L = new cli.Logger("farkleportal") 

L.connect(); // error

Error:

/var/spool/cocaine/farkleportal/node_modules/cocaine/lib/client/service.js:152
    (_this._client || client).resolve(_this._name, _resolveDone)
                              ^

Cocaine module version: "0.4.1-6".

That's an inaccuracy in readme, since cli.Logger is a factory function, not a constructor. So, you can create logger like this:

var cocaine = require('cocaine');
var cli = new cocaine.Client(); // ["localhost", 10053]
var L = cli.Logger("farkleportal") 

L.connect();
