 app.use(function(req, res, next) {
      res.on('end', function() {
        console.log('end') ; //Portsion need to execute once response send
      })

      next();
    })

In the last versions of node.js the correct event to watch for end or close actions is finish (documentation). So your code should be

app.use(function(req, res, next) {
  res.on('finish', function() {
    console.log('end') ;
  })

  next();
})
