How to use shared project in node.js

Question

I have project structure like this using node express of javascript

• Shared
• • Models
• • Helpers
• • Utils
• API
• Socket

I have some shared logic in API and Socket which I wanted to share in Shared poject, but sure the best approach.

Also, in the code how do I use the Models, Helps and Utils .

The should should work with npm, package.json, nodemon and docker.

Please suggest.

I have tried this in the app project

"shared" : "file:../shared"

but it did not work.
