Passport: Unknown authentication strategy "local" - node.js

Question

I'm new to NodeJS and I try to build a login/registration system. Registration works fine but I'm currently unable to login.
I find a example app using passport and nodejs, so based on this example I build the registration form and the login form.

When I try to login I get an 'Unknown authentication strategy "local" error'. Can anybody explain what I'm doing wrong?
My code
(edit: added some changes from answers/comments and filenames)
Express config (config/express.config.js)
app.use(session({
store: new MongoStore({
url: 'mongodb://' + config.url + ':' + config.port + '/' + config.name
}),
secret: 'secretkey',
key: 'skey.sid',
resave: false,
saveUninitialized: false,
cookie : {
maxAge: 604800000 //7 days in miliseconds
}
}));
app.use(passport.initialize());
app.use(passport.session());
require(path.join(__dirname, 'auth.config'))(passport); //Load passport config
app.use(function(req, res, next) {
req.resources = req.resources || {};
// res.locals.app = config.app;
res.locals.currentUser = req.user;
res.locals._t = function (value) { return value; };
res.locals._s = function (obj) { return JSON.stringify(obj); };
next();
})
Passport config (config/auth.config.js)
var path = require('path');
var passport=require('passport');
var User = require(path.join(__dirname, '..', 'models', 'user.model'));
module.exports = function(passport) {
passport.serializeUser(function(user, done){
done(null, false);
});
passport.deserializeUser(function(id, done){
console.log("deserializeUser called", id);
User.findById(id, function (err, user) {
done(err, user);
});
});
//load strategy files
require(path.join(__dirname, 'strategies', 'local-strategy'));
//TODO: Facebook
//TODO: Twitter
//TODO: Google
}
Local strategy (/config/strategies/local-strategy.js)
var passport = require('passport');
var LocalStrategy = require('passport-local').Strategy;
var mongoose = require('mongoose');
var User = mongoose.model('User');
module.exports = function () {
console.log("LocalStrategy called");
passport.use(new LocalStrategy({
usernameField : 'username',
passwordField : 'password'
},
function(username, password, done) {
User.authenticate(username, password, function(err, user) {
if (err) {
return done(err);
}
if(!user) {
return done(null, false, {message: 'Invalid username or password'});
}
return done(null, user);
})
}))
}
Auth Controller (login only) (/controllers/auth.controller.js)
module.exports.loginUser = function(req,res, next) {
console.log("Auth.config", path.join(__dirname, 'strategies', 'local-strategy'))
passport.authenticate('local', function (err, user, info) {
if (err || !user) {
console.log("Error", info);
return res.status(400).send(info);
}
req.logIn(user, function(err) {
if (err) {
return next(err);
// return res.status(404).send("Username or password incorrect");
}
})
res.status(200).json(user);
})(req, res, next);
}

Answer 1

You forgot to import passport config file in your app.js.
import passport config after initializing passport.
app.use(passport.initialize());
app.use(passport.session());
// Add the line below, which you're missing:
require('./path/to/passport/config/file')(passport);

i have done like this and it worked
$npm install passport-local
var passport = require('passport');
var LocalStrategy = require('passport-local').Strategy; /* this should be after passport*/
passport.use(new LocalStrategy(
function(username, password, done) {
User.findOne({ username: username }, function(err, user) {
if (err) { return done(err); }
if (!user) {
return done(null, false, { message: 'Incorrect username.' });
}
if (!user.validPassword(password)) {
return done(null, false, { message: 'Incorrect password.' });
}
return done(null, user);
});
}
));

this fix the error. need to use 'local' when you create a new LocalStrategy
passport.use('local', new LocalStrategy({
usernameField:'useName',
passwordField: 'password',
passReqToCallback: true
