Middleware fix for Node Up And Running Chp 2

readme.md

In chp 2 of Node Up and Running http://chimera.labs.oreilly.com/books/1234000001808/ch02.html#I_sect12_d1e1886 ex 2-15 and the surrounding and probably some following stuff don't work properly. I think I kind of fixed it with the following fakeNoTwit.js and twTest.js files which work to make the simple server and test it a little.

Twas a simple fix. Just had to use the body-parser module because .bodyParser() was removed from the main Express module because of security flaws I guess. Have fun playing with node!

fakeNoTwit.js

var express = require('express');
var middler = require('body-parser')

var app = express()
app.listen(8000)
app.use(middler());
var tweets = []

app.get('/', function(req, res) {
  res.send('Welcome to Node Twitter')
})

app.post('/send', function(req, res) {
  if (req.body && req.body.tweet) {
    console.log(req.body.tweet)
    tweets.push(req.body.tweet)
    res.send({status:"ok", message:"Tweet received"})
  } else {
    //no tweet?
    res.send({status:"nok", message:"No tweet received"})
  }
})

app.get('/tweets', function(req,res) {
  res.send(tweets)
})

twTest.js

var http = require('http'),
    assert = require('assert')

var opts = {
  host: 'localhost',
  port: 8000,
  path: '/send',
  method: 'POST',
  headers: {'content-type':'application/x-www-form-urlencoded'}
}

var req = http.request(opts, function(res) {
  res.setEncoding('utf8')

  var data = ""
  res.on('data', function(d) {
    data += d
  })

  res.on('end', function() {
    assert.strictEqual(data, '{"status":"ok","message":"Tweet received"}')
  })
})

req.write('tweet=testing')
req.end()
