app.js

#!/usr/bin/env node

/**
 * app.js
 *
 * Use `app.js` to run your app without `sails lift`.
 * To start the server, run: `node app.js`.
 * Or directly: `./app.js`.
 *
 * This is handy in situations where the sails CLI is not relevant or useful,
 * such as when you deploy to a server, or a PaaS like Heroku.
 *
 * For example:
 *   => `node app.js`
 *   => `npm start`
 *   => `forever start app.js`
 *   => `node debug app.js`
 *
 * The same command-line arguments and env vars are supported, e.g.:
 * `NODE_ENV=production node app.js --port=80 --verbose`
 *
 * For more information see:
 *   https://sailsjs.com/anatomy/app.js
