I have a Vue SSR-application and for some components, I need to know whether they run on Node during server-side rendering or whether they run on the browser.

I've set the process env in the Webpack config like 

process.env.VUE_ENV === 'server'

which works. But for various reasons, I need a detection independent of the built environment.

I'd like to check for the browser/node in the created() hook.

How would I do that?

    You can try to access a browser specific object (like navigator object) within your `created()` hook - and catch the error it throws when trying to access this object on nodejs fails – Mortz Nov 21 '18 at 10:37

I took the following line -verbatim- from the Vue.js source code ..

const inBrowser = typeof window !== 'undefined';

You can use it to verify if your code is running in the browser.
