Express4 returns error in a POST request

I recive a "Express.js returns error in a POST request" when I try to send data in a POST resquest. How I can fix it?

My app.js code:

var express = require('express');
var bodyParser = require('body-parser')
var app = express();
var form = require('./routes/form')(app);

app.set('views', __dirname + '/views');
app.set('view engine', 'ejs');
app.use(express.static(__dirname + '/public'));
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());

app.listen(7777, function(){
  console.log("Running...")
});

My form.js code:

module.exports = function(app){

  app.get('/form', function(req, res){
    res.render('form');
  });

  app.post('/send', function(req, res){
    console.log(req.body.name);
  });

};

My form.ejs code:

<form action="/send" method="post">
  <input type="text" name="name" value="">
  <input type="submit" value="Submit">
</form>

Console error:

TypeError: Cannot read property 'name' of undefined

Thanks for the attention!

You dont yet mounting your middlewares on app when you pass it to form. you first should mount your middle wares at least the body-parser one which is responsible for populating req.body. so move:

var form = require('./routes/form')(app);

after your body-parser middle ware and it should work.

In general order matters.

Try removing value="" from your input. I think you are setting always as empty this way.
