 *
 * All content of this folder will be copied as is to the output folder. So only import:
 *  1. node_modules (and yarn/npm install dependencies -- NOT to devDependecies though)
 *  2. create files in this folder and import only those with the relative path
 *
 * Note: This file is used only for PRODUCTION. It is not picked up while in dev mode.
 *   If you are looking to add common DEV & PROD logic to the express app, then use
 *   "src-ssr/extension.js"
