/**
 * Webpack common configuration.
 * it:
 * - Define the app entry point (./src) -> Where webpack will start compiling/bundling
 * - Define where assets will be served at by our webserver  (static/)
 * - Clean previous build on each build
 * - Generates the index.html file automatically by injecting bundled assets in it (css, js)
 * - Allow to load html files as strings in js code (i.e: import htmlString from './myHtmlFile.html)
 * - Allow to automatically generates the dependencies injection for angularJS components annotated with
 *   `'ngInject';` or `@ngInject` in comments. See https://docs.angularjs.org/guide/di
