    I spent a few hours chasing down just how to get my static assets (css, fonts, images) to load in an Electron app built using electron-forge v6 (https://www.electronforge.io/) and its webpack plugin (https://www.electronforge.io/config/plugins/webpack) while in development mode. There really isn't any documentation available online, either in the electron-forge documentation or in places like blogs or gists or stackoverflow. So I thought I'd put it down here.
Step 1

Load CopyWebpackPlugin
npm i -D copy-webpack-plugin

Step 2

Use the plugin to move your directories into place.
It's important that they be at bare minimum in .webpack/renderer, since that is the root used for localhost
webpack.renderer.config.js
const path = require('path');
const CopyWebpackPlugin = require('copy-webpack-plugin');
const assets = [ 'img', 'css', 'fonts' ]; // asset directories

module.exports = {
  // Put your normal webpack config below here
  module: {
    rules: require('./webpack.rules'),
  },
  plugins: assets.map(asset => {
    return new CopyWebpackPlugin([
      {
        from: path.resolve(__dirname, 'src', asset),
        to: path.resolve(__dirname, '.webpack/renderer', asset)
      }
    ]);
  })
};

Step 3

IMPORTANT: Access files with absolute paths

Files without absolute paths do not appear to work, even when everything is relatively placed.
