(Not sure if this is the right place for this)
As of April 2018, the production deployment at https://vuejs-tips.github.io/cheatsheet/ seems to be running in development mode.
On load, the app prints this banner to the browser console:
You are running Vue in development mode.
Make sure to turn on production mode when deploying for production.
See more tips at https://vuejs.org/guide/deployment.html
This seems to be happening across all browsers.
Is this intentional?
