/**
 * Dashy is built using Vue (2). This is the main Vue and Webpack configuration
 *
 * User Configurable Options:
 * - NODE_ENV: Sets the app mode (production, development, test).
 * - BASE_URL: Root URL for the app deployment (defaults to '/').
 * - INTEGRITY: Enables SRI, set to 'true' to activate.
 * - USER_DATA_DIR: Sets an alternative dir for user data (defaults ./user-data).
 * - IS_DOCKER: Indicates if running in a Docker container.
 * - IS_SERVER: Indicates if running as a server (as opposed to static build).
 *
 * Documentation:
 * - Vue CLI Config options: https://cli.vuejs.org/config
 * - For Dashy docs, see the repo: https://github.com/lissy93/dashy
