javascript - Using passport.socketio with express and passport-local-mongoose -

i'm trying make easy chat room using passport , socket.io, need know has emit message using socket.io, use passport.socketio this, , use module passport-local-mongoose simplify using passport.

however, when add

io.use(passportsocketio.authorize({     cookieparser: cookieparser,     secret: 'lqcbfu1wfjagklfzng4x',     store: sessionstore })); 

in app.js caused client-side socket not connected server (if commented block, message server's console )

i thought may due misusing of passport.socketio or module passport-local-mongoose, don't know what's wrong qaq.

app.js:

var express = require('express'); var path = require('path'); var favicon = require('serve-favicon'); var logger = require('morgan'); var cookieparser = require('cookie-parser'); var bodyparser = require('body-parser'); var session = require('express-session'); var flash = require('req-flash'); var helmet = require('helmet'); var passport = require('passport'); var mongoose = require('mongoose'); var localstrategy = require('passport-local').strategy; var socketio = require('socket.io'); var passportsocketio = require('passport.socketio');  var app = express();  // view engine setup app.set('views', path.join(__dirname, 'views')); app.set('view engine', 'ejs');  // midllewares preprocess things app.use(favicon(path.join(__dirname, 'assets', 'favicon.ico'))); app.use(helmet()); app.use(logger('dev')); app.use(bodyparser.json()); app.use(bodyparser.urlencoded({ extended: false })); app.use(cookieparser()); var sessionstore = new session.memorystore(); app.use(session({     secret: 'lqcbfu1wfjagklfzng4x',     store: sessionstore,     resave: false,      saveuninitialized: false,  })); app.use(passport.initialize()); app.use(passport.session()); app.use(flash()); app.use(express.static(path.join(__dirname, 'assets')));  app.use('/', require('./routes/index')); app.use('/users', require('./routes/users'));  // passport config var account = require('./models/account'); passport.use(new localstrategy(account.authenticate())); passport.serializeuser(account.serializeuser()); passport.deserializeuser(account.deserializeuser());  // make socket.io able use passport var io = socketio(); io.use(passportsocketio.authorize({     cookieparser: cookieparser,     secret: 'lqcbfu1wfjagklfzng4x',     store: sessionstore })); app.io = io;  (...)

models/socketio.js:
