JavaScript Express Basics (2015) Serving Static Files in Express Review Static Middleware

Express Basics > Serving Static Files in Express > Review Static Middleware Challenge

Why does the app.use method not work in this Challenge question when it's identical to the previous lesson video? I'm getting a "Bummer! _dirname is not defined" error message.

app.js
'use strict';

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

var app = express();

app.use('/static', express.static(_dirname + '/public'))

app.set('view engine', 'jade');
app.set('views', __dirname + '/templates');

app.get('/', function(req, res){
  res.render('index');
});

app.get('/blog/:title?', function(req, res){ 
  var title = req.params.title;
  if (title === undefined) {
    res.status(503);
    res.send("This page is under construction!");
  } else {
    var post = posts[title] || {};
    res.render('post', { post: post});
  }
});

app.listen(3000, function() {
  console.log("The frontend server is running on port 3000!");
});

Hi, __dirname requires 2 underscores, then you're good to go :)

Jeremiah Bushau:

Thanks. I'll try it. It was not mentioned in the lesson video.
