i tried change webpack config js, paths and rules. but its not works. also guides for webpack 4 generally. and webpack docs is very complex, so i trying on boilterplate

Webpack generates a JS file for each resource defined in the entry option. So works Webpack.

To remove generated empty JavaScript files you can use the webpack-remove-empty-scripts plugin.

Install

npm install webpack-remove-empty-scripts --save-dev

Usage

Add the plugin to webpack.config.js:

const RemoveEmptyScriptsPlugin = require('webpack-remove-empty-scripts');

module.exports = {
  ...
  plugins: [
    // removes the empty `.js` files generated by webpack
    new RemoveEmptyScriptsPlugin(),
    ...
  ],
  ...
};
