// Express/Connect top-level generic
// This example demonstrates adding a generic JSON and URL-encoded parser as a top-level middleware, which will parse the bodies of all incoming requests. 
// This is the simplest setup.

var express = require('express')
var bodyParser = require('body-parser') 
var app = express() 

// parse application/x-www-form-urlencoded
app.use(bodyParser.urlencoded({ extended: false })) 

// parse application/json
app.use(bodyParser.json())

  res.setHeader('Content-Type', 'text/plain')  
  res.write('you posted:\n')  
res.end(JSON.stringify(req.body, null, 2))})
