Node.js Express JS - Cannot find module './config/express'

Question

Im Learning to make a web application with Node.js Express JS.

When I run my server.js

$ node server

I get this

Error: Cannot find module './config/express'
at Function.Module._resolveFilename (module.js:538:15)
at Function.Module._load (module.js:468:25)
at Module.require (module.js:587:17)

at Module.load (module.js:556:32)
at tryModuleLoad (module.js:499:12)
at Function.Module._load (module.js:491:3)

my server.js file is like this...

server.js:

var express = require('./config/express');
var app = express();
app.listen(3000);
module.exports = app;
console.log('Server running at http://localhost:3000/');

before doing this I run this command in the root of my app

npm install

Here is a like to a picture to show you the project folder structure I have.

I dont understand why cannot find module './config/express' while apparently the folder structure is fine.

Any idea??

Answer 1

after installing npm, you should try express installation into your project directory as

npm install express

it will create node_modules of express. then you should use

var express = require('express');

Answer 2

Your server.js doesn't work because express.js file into config folder create confusion. Change the name from express.js to init.express.js and then it will work.
