DB connection error handling with monk

I am using monk on a code that looks like

var monk = require('monk')
var db = monk('localhost/mydb')

if(!db){
  console.log('no connection')
}

when I run it, console logs 'no connection', but I would like to know why it is not connecting, (maybe see a stack trace' how do I do that?

Looks like this is known bug. https://github.com/Automattic/monk/issues/24

In your snippet, monk(url) returns db object whether connection or not.

This is db object on connection

> dbgood
{ driver:
   { _construct_args: [],
     _native:
      { domain: null,
        _events: {},
        _maxListeners: 10,
        databaseName: 'dbgood',
        serverConfig: [Object],
        options: [Object],
        _applicationClosed: false,
        slaveOk: false,
        bufferMaxEntries: -1,
        native_parser: true,
        bsonLib: [Object],
        bson: [Object],
        bson_deserializer: [Object],
        bson_serializer: [Object],
        _state: 'connected',
        pkFactory: [Object],
        forceServerObjectId: false,
        safe: false,
        notReplied: {},
        isInitializing: true,
        openCalled: true,

        logger: [Object],

        serializeFunctions: false,
        raw: false,
        recordQueryStats: false,
        retryMiliSeconds: 1000,
        numberOfRetries: 60,
        readPreference: [Object] },
     _emitter:
      { domain: null,
        _events: {},
        _maxListeners: 50 },
     _state: 2,
     _connect_args: [ 'mongodb://localhost/dbgood', [Object] ] },
  helper:
   { toObjectID: [Function],
     id:
      { [Function: ObjectID]
        index: 10690856,
        createPk: [Function: createPk],
        createFromTime: [Function: createFromTime],
        createFromHexString: [Function: createFromHexString],
        isValid: [Function: isValid] } },
  collections: {},
  options: { safe: true },
  _events: {} }

This is db object when mongodb is not running

> dbbad
{ driver:
   { _construct_args: [],
     _native: null,
     _emitter:
      { domain: null,
        _events: {},
        _maxListeners: 50 },
     _state: 0,
     _connect_args: [ 'mongodb://dbbad', [Object] ] },
  helper:
   { toObjectID: [Function],
     id:
      { [Function: ObjectID]
        index: 10690856,
        createPk: [Function: createPk],
        createFromTime: [Function: createFromTime],
        createFromHexString: [Function: createFromHexString],
        isValid: [Function: isValid] } },
  collections: {},
  options: { safe: true },
  _events: {} }

Maybe for now, you can use _native._state for checking connection.
