Must use import to load ES Module webpack.config.js

I decided to try the es6 Node modules.js (those that are .mjs or "type" = "module"). I write the code in typescript, the ts-loader webpack should compile the code into js files. The problem is that webpack does not want to be friends with the es6 environment and gives an error:

Must use import to load ES Module webpack.config.js


// webpack.config.js
import path from 'path'

export default {
  mode: 'development',
  target: 'node',
  entry: ['./main.ts'],
  output: {
    filename: 'main.js',
    path: path.resolve(__dirname, 'dist'),
  },
  module: {
  rules: [
      {
        test: /\.tsx?$/,
        use: 'ts-loader',
        exclude: /node_modules/,
      },
    ],
  },
};

UPD:

Here is the full text of the error

Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: /home/admin/web/31_MyCMS2/webpack.config.js require() of ES modules is not supported. require() of /home/admin/web/31_MyCMS2/webpack.config.js from /usr/lib/node_modules/webpack-cli/bin/utils/convert-argv.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules. Instead rename webpack.config.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from /home/admin/web/31_MyCMS2/package.json.

Renamed webpack. config.js => webpack.config.mjs

Added the webpack.config.cjs file:

module.exports = async (env, argv) => {
  const config = await import('./webpack.config.mjs')
  return config.default(env, argv)
}

Calling webpack --config webpack.config.cjs --node-arg="--experimental-modules --experimental-vm-modules"

Mistake:

TypeError: Invalid host defined options at module.exports (/home/admin/web/31_MyCMS2/webpack.config.cjs:2:18)
