Keep getting a TypeError: Cannot read property 'title here' of undefined.

Very frustrating and I dont know why...

'use strict';

var express = require('express'),
      posts = require('./mock/posts.json');

var app = express();

//Creates a server request.
app.get('/', function (req, res) {
  res.send("<h1>Im creating my first express app! Looking good</h1>");
});

app.get('/blog', function (req, res) {
  res.send(posts);
});

app.get('/blog/:title', function (req, res) {

  var title = req.params.title;
  var post = req.posts[title];
  res.send(post);
});

//tells server request to listen on '3000'.
app.listen(3000, function () {
  console.log('*** The frontend server is running on port (3000) ***');
});

{
  "I like to run": {
    "title": "I like to run",
    "description": "Running is great for you, It's hard to get out there and do it but I'm always happy when I do."
  },
  "Fake content": {
    "title": "This is a bunch of fake content",

remove req

app.get('/blog/:title', function (req, res) {

  var title = req.params.title;

  //remove req. below
  //var post = req.posts[title];

  var post = posts[title];

  res.send(post);

});

That worked! Thank you very much. I put this down temporarily but will now come back to it.
