How check if Vue is in development mode?

When I run my Vue app, the console shows:

You are running Vue in development mode.
Make sure to turn on production mode when deploying for production.

Answer 1

Webpack is used for almost all of my Vue projects, so I check to see if webpackHotUpdate is present.

 if (webpackHotUpdate) {
      console.log('In Dev Mode');
 }

It's present in the window object if the webpack dev server is running.
