Question

Almost for all third-party modules WebStorm’s autocomplition cannot resolve methods/fields. Under autocompletion I mean also all intellisense-like features.
For example:

var async = require('async');
async.series() //WebStorm's tooltip says: Unresolved function or method series()

At the same time it resolves

async.exports.series(). 

But this leads to runtime error:

TypeError: Cannot call method 'series' of undefined

For my own modules I’ve found workaround. If I do in the module:

var myModule = module.exports;
myModule.someMethod = function(){
...
}

Then autocomplition for someMethod works fine.

Regarding all of above I have a bunch of questions.
1. Why the ide fails to resolve async.series()?
2. Why async.exports.series() leads to runtime error?
3. How to make autocomplition work?

WebStorm 5.0.4.

Use new as follows:

var async = new require('async');
