TypeError: Cannot read property 'myemail' of undefined

Question

I am trying to make login system using html,nodejs,express.

I have created a form and gave the input tag name as myemail, I used this name just to display email in console.But I am getting this error.

I have checked all the answers provided in the similar questions, but none of them worked for me. app.js

const express = require('express');
const path = require('path');
const session = require('express-session');
const bodyparser = require('body-parser');
const app = express();

const port = process.env.PORT || 5000;

const router = require('./router');
const bodyParser = require('body-parser');

app.set('view engine','ejs');
app.use('/static',express.static(path.join(__dirname,'public')));
app.use('/assets',express.static(path.join(__dirname,'public/assets')));
app.use('/route',router);

app.use(bodyparser.urlencoded({extended:true}));
app.use(bodyparser.json());

app.use(session({
    secret:'secret',
    resave:'false',
    saveUninitialized:'true'
}));

app.get('/',(req,res) =>{
    res.render('base',{title:'Login'})
})
app.listen(port,console.log("listening.."));

router.js

const express = require('express');
const router = express.Router();

const user = {
    email : 'abc@gmail.com',
    password : 'abcd'
};

router.post('/login',(req,res)=>{

    console.log(req.body.myemail);
    res.end("Login Successful");

});

module.exports = router;
