Node –experimental-modules – Error: Cannot find module

Tags: , , ,



I am getting an error when trying to import a local file, though no problem when using npm packages.

server.js

import express from 'express'
import next from 'next'

import apis from './src/server/api'

api.js

export default {
  ello: 'bye',
  jamie: 'hey'
}

Starting app

node --experimental-modules --inspect server.js

Error

For help, see: https://nodejs.org/en/docs/inspector

Answer

I’m answering my own question if anybody else has this problem.

It turns out in experimental mode you need to define the full path with extension. So I am trying to import index.js thinking it will know.

To fix it:

import express from 'express'
import next from 'next'
import api from './src/server/api/index.js'
