Express.js req.body undefined

I have this as configuration of my Express server

app.use(app.router); 
app.use(express.cookieParser());
app.use(express.session({ secret: "keyboard cat" }));
app.set('view engine', 'ejs');
app.set("view options", { layout: true });
//Handles post requests
app.use(express.bodyParser());
//Handles put requests
app.use(express.methodOverride());

But still when I ask for req.body.something in my routes I get some error pointing out that body is undefined. Here is an example of a route that uses req.body :

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

I read that this problem is caused by the lack of app.use(express.bodyParser()); but as you can see I call it before the routes.

Any clue?

UPDATE July 2020

express.bodyParser() is no longer bundled as part of express. You need to install it separately before loading:

npm i body-parser

// then in your app
var express = require('express')
var bodyParser = require('body-parser')
 
var app = express()
 
// create application/json parser
var jsonParser = bodyParser.json()
 
// create application/x-www-form-urlencoded parser
var urlencodedParser = bodyParser.urlencoded({ extended: false })
 
// POST /login gets urlencoded bodies
app.post('/login', urlencodedParser, function (req, res) {
  res.send('welcome, ' + req.body.username)
})
 
// POST /api/users gets JSON bodies
app.post('/api/users', jsonParser, function (req, res) {
  // create user in req.body
})

You must make sure that you define all configurations BEFORE defining routes. If you do so, you can continue to use express.bodyParser().

An example is as follows:

var express = require('express'),
    app     = express(),
    port    = parseInt(process.env.PORT, 10) || 8080;

app.configure(function(){
  app.use(express.bodyParser());
});

app.listen(port);
    
app.post("/someRoute", function(req, res) {
  console.log(req.body);
  res.send({ status: 'SUCCESS' });
});
