/**
 * Webpack development configuration (merged with common one).
 * it overrides the webpack.common.js configuration and:
 * - Set mode to development -> This mode is used by some plugins and webpack to prevent minifying assets etc...
 * - Generates a sourcemap of bundled code -> Allow to easily debug js code (do not use in prod)
 * - Remove some bundling optimization to speed it up
 * - Allow Load css files (import './myCssFile.css') -> Css rules will be automatically added to index.html into a <style></style> tag.
 * - Allow to load fonts and images (import './myFont.eot'; import './someImage.jpg')
