Why I'm getting Error [ERR_MODULE_NOT_FOUND]: Cannot find module when running the server

Question

I'm doing a startup server. Basically It has initial setup with express and nodemon dependencies. Unfortunately, I'm getting ERR_MODULE_NOT_FOUND when running yarn dev or npm run dev Here is the code and file structure I have.

Answer 1

You need to add .js extension index.js:

import { SampleExport } from "../path/file.js"

In my opinion, it is better to use .env files together with some npm package or even a json file.
