node.js require cannot find custom module

Question

Here is the project structure:

/
  app.js
  package.json
  /node_modules
  /app
    config.json
    /frontend
      assets and html tpls
    /modules
      couch.js
      raeume.js
      users.js

I require config.json, raeume.js and users.js from app.js and it all works fine.

var config   = require('./app/config');
var raeume   = require('./app/modules/raeume');
var users    = require('./app/modules/users');

Then I require config.json and couch.js from user.js the same way and it won't find anything.

var couch     = require('./app/modules/couch');
var config    = require('./app/config');

I guess it should find it. After some research I saw a diverse landscape of problems inclusive how node is compiled. Thus included: I work on osx 10.8 with node v0.10.7.

The path is relative to the directory in which you are requireing the files, so it should be something like:

var couch = require('./couch');
var config = require('../config');

A bit of clarification, if you write

var couch = require('./couch');

you are trying to require the couch module which resides in the current directory, if you write

var couch = require('couch');

you are trying to require the couch module installed via npm.

I try relative: var couch = require('couch'); var config = require('../config'); finds config but not couch. – thgie May 20 '13 at 15:22

You missed the `./` in `require('couch');` – Alberto Zaccagni May 20 '13 at 15:27
I doesn't work with me: when I do either `require('qmlweb')` or `require('./node_modules/qmlweb')`, it says the module cannot be found. Yet qmlweb is installed in node_modules/qmlweb, and all the files are there. – Michael Feb 24 '16 at 11:11

Here is how you do it :

var users    = require('./../modules/users');

It must be:

var config = require(../../app/config)

var couch = require(./couch) (same directory)
