express.static：无法获取/

Question

I'm learning how to use node.js on this blog/website: http://blog.modulus.io/absolute-beginners-guide-to-nodejs

Everything worked fine until I got to the part Doing Something Useful - Express

Express seemed to install fine with npm.

Here's my code:

var express = require('express'),
    app = express();

app.use(express.static(__dirname + '/Public'));

app.listen(8080);

I put that into a file called test.js and put it in a folder called Public . In that folder I also added a html doc with just a few words.

On the browser ´ http://localhost:8080 ´ shows up with Cannot GET / and ´ http://localhost:8080/index.html ´ shows Cannot GET /index.html

Answer 1

You need to put the public folder on the same level as your test.js file, like this

.
├── Public
│   └── index.html
└── test.js

1 directory, 2 files

It seems that you put your test.js in your Public directory.

__dirname means the name of the directory of the current file, that is why your Public directory should be in the same folder than your js file.
