Generating npm package without including file extensions in imports

I am currently working on creating an internal library for my workplace.

Everything seems to be going smoothly until I try to use it in another project. It appears that the file extension in all of the import statements has disappeared during the npm pack phase.

To illustrate, the statement:

import * as Account from './modules/account.js'

turns into:

import * as Account from './modules/account'

This change causes the import to fail.

Initially, I thought this issue might have occurred because I used the .js extension instead of .mjs, but even switching to .mjs produces the same problem.

main.js

import * as Account from './modules/account.js'

Account.secretSquirrel().then( data => console.log( 'inspector gadget', data ) );

node version

v16.15.0

package.json (confidential information hidden)

{
  "name": "@Nunya",
  "version": "0.0.0",
  "description": "Nunya",
  "private": true,
  "main": "./lib/main.js",
  "scripts": {
    "build": "npm run pack",
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "repository": {
    "type": "git",
    "url": "Nunya.git"
  },
  "author": "Nunya",
  "license": "ISC",
  "type": "module",
  "exports": {
    ".": {
      "require": "./lib/main.js",
      "default": "./lib/main.js"
    },
    "./Account": "./lib/modules/account.js"
  }
}

Based on my analysis, this discrepancy should not be occurring. I am unsure how to address it

Answer №1

It appears that the solution to resolving this issue involves including an import object that sets the resolutions for relative paths in the package.json. While I believe there may be an automated method to achieve this, I am currently unaware of it.

If you have any insight on this matter, kindly share with me.
