nodejs app works fine when starting with node, but fails when starting from index.html in nwjs

I’m using next technologies in my app:
nodejs v7.2.1
nwjs v0.19.0
node in nwjs v7.2.0
Windows 10 Pro x64
npm ffi
npm ref
npm ref-array
npm sleep
MasterRD.dll

Code, that fails:

var CARDREADER = (function() {
    window.CARDREADER = CARDREADER;

    var ffi = require('../cardreader/node_modules/ffi'),
        ref = require('../cardreader/node_modules/ref'),
        ArrayType = require('../cardreader/node_modules/ref-array'),
        Sleep = require('../cardreader/node_modules/sleep'),
        CharArray = ArrayType(ref.types.char),
        chatPtr = ref.refType('char'),
        intPtr = ref.refType('int32'),
        BUFFER_LENGTH = 20,
        stateAvailabilityCard = false,
        statusConnected = 1;

    RFIDfunctions = ffi.Library('../cardreader/MasterRD', {

    return {
