The post request in nodejs return nothing for passport authentication

Question

Am a newbie to Node.js, Am getting only a loading page in node.js post request when running the passport authentication. Can anyone help me

my Router.js

var express = require('express');
var router = express.Router();
var passport = require('passport');
var User = require('../models/user-model');
var Local = require('../config/passport-local');


/* GET home page. */
router.get('/', function(req, res, next){
  res.render('index',{ title : 'Login'});
});

router.post('/login', (req, res, next) => {
  passport.authenticate('local',(req, res,next) => {
    console.log('ok');  
  });
}, (req, res, next) => {

});
module.exports = router;

passport-local.js

var passport = require('passport');
var LocalStrategy = require('passport-local').Strategy;

var User = require('../models/user-model')

passport.use(new LocalStrategy(
    function(username, password, next) {
        console.log('auth');
        User.findOne({username: username}, function(err, user) {
            console.log('passport');
            if(err) { return  next(err);}
            if(!user) { 
                return next(null, false, {message : 'invalid username'});
            }
            if(!user.validPassword(password)) {
                return next(null, false, {message: 'invalid password'})
            }
            return next(null, user);
        });
    }
));

App.js

var createError = require('http-errors');
var express = require('express');
var path = require('path');
var cookieParser = require('cookie-parser');
var logger = require('morgan');
var mongoose = require('mongoose');
var passport = require('passport');

var indexRouter = require('./routes/index');
var usersRouter = require('./routes/users');
var commonKeys = require('./config/keys');

var app = express();

//connect mongoDb 
mongoose.connect(commonKeys.mongoDB.connect + '/' + commonKeys.mongoDB.database, { useNewUrlParser: true });

// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'pug');


app.use(logger('dev'));
app.use(express.json());
app.use(express.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));

//app.use(flash());
app.use(passport.initialize());
app.use(passport.session());


app.use('/', indexRouter);
app.use('/users', usersRouter);


// catch 404 and forward to error handler
app.use(function(req, res, next) {
  next(createError(404));
});

// error handler
app.use(function(err, req, res, next) {
  // set locals, only providing error in development
  res.locals.message = err.message;
  res.locals.error = req.app.get('env') === 'development' ? err : {};

  // render the error page
  res.status(err.status || 500);
  res.render('error');
});

module.exports = app;

I am trying to learn passport authentication in nodejs. it is much appriciated if anyone can explain the error in this code and why its not working.

You need to update your code accordingly:

router.post('/login',
  passport.authenticate('local'),
  function(req, res) {
    // If this function gets called, authentication was successful.
    // `req.user` contains the authenticated user.
    res.send('Done');
  });

Here's more documentation.
