app.js

/**
 * app.js
 *
 * Use `app.js` to run your app without `sails lift`.
 * To start the server, run: `node app.js`.
 *
 * This is handy in situations where the sails CLI is not relevant or useful.
 *
 * For example:
 *   => `node app.js`
 *   => `forever start app.js`
 *   => `node debug app.js`
 *   => `modulus deploy`
 *   => `heroku scale`
 *
 *
 * The same command-line arguments are supported, e.g.:
 * `node app.js --silent --port=80 --prod`
