Passport-local: Lain ~ Satu-satunya masalah kredensial yang hilang: D

Apakah bagian ini, yang di passport.js, salah?

 router.post('/login', function(req, res, next) {
   passport.authenticate('local', {
     sucessRedirect: '/',
     failureRedirect: '/users/login',
     failureFlash: true
   })(req, res, next)
 })

paspor.js

const LocalStrategy = require('passport-local').Strategy;
const User = require('../models/user')
const config = require('../config/database');
const bcrypt = require('bcryptjs')


module.exports = function(passport) {
  // Local Strategy
  passport.use(new LocalStrategy(function(username, password, done) {
    //Match Username
    let query = {
      username: username
    };
    User.findOne(query, function(err, user) {
      if (err) throw err;
      if (!user) {
        return done(null, false, {
          message: 'No User Found'
        })
      }

      //Match Password
      bcrypt.compare(password, user.password, function(err, isMatch) {

        if (isMatch) {
          return done(null, user);

        } else {

Satu hal lagi, file database.js ini ada di folder config
untuk apa rahasia variabel itu? Kata orang bisa apa saja.
database.js

module.exports = {
  database: 'mongodb://localhost:27017/nodekb',
  secret: 'anything'
}
