Get real page source

Nowadays with all these javascript frameworks if you just do a view page source, you will only get the skeleton app div with a bunch of script tags. To see the expanded real page source, type in the following in the web console.

copy(document.querySelector('html').outerHTML)

That will copy the computed dom to your clipboard, then you just need to paste it to your text editor. You will see all the other dom nodes which the js files added to the app div.
