Hello my application created with node.js I have several modules: the database, the Api, customer service, etc ... Well, in some I have to refer to another in the package.json file but I do not know if I'm doing it right, because when I start linking them, it does not end up working. I have all the modules in the same directory, each one in your directory. The package.json file sometimes flags me the error: this module is not installed , because if it is in node_modules . Am I calling the module well in the package.json file? "michaelgram-client": "file:../michaelgram-client" , Thanks, I show part of package.json

EDIT: To add code that was suggested to me.

"license": "MIT",
  "dependencies": {
    "aws-sdk": "^2.239.1",
    "axios": "^0.18.0",
    "babel-polyfill": "^6.26.0",
    "body-parser": "^1.18.3",

    "intl-messageformat": "^2.2.0",
    "intl-relativeformat": "^2.1.0",
    "materialize-css": "^0.100.2",
    "michaelgram-client": "file:../michaelgram-client",
    "multer": "^1.3.0",

    "title": "^3.2.0",
    "vinyl-source-stream": "^2.0.0",
    "yo-yo": "^1.4.1"
  },

Simplifying the structure of the project.

Project structure

~root
  - moduloA
     - index.js
     - ...
  - moduloB
    -index.js
    - ...

Suppose I am doing the moduloA module whose input file ( main ) is index.js . In that package.json there must be:

{
 ...
 "main": "index.js",
 ...
}

Now we are working on another module moduloB .

If we want to install the local module moduloA taking into account the structure of the project, we would do:

npm install ../moduloA --save

Anywhere in module B you can load your module:

import ... from 'moduloA' (o require('moduloA'))
