javascript - Does PhantomJS support ES6 for serving angularjs app to crawlers and bots?

I am trying to use ajax-seo for an Angularjs app to serve html piled content from a PhantomJS webserver`. But it's not rendering the plete page. It's just giving the following response

<html><head></head><body></body></html>

I have followed the instructions well but no luck so far. So I'd like to know whether PhantomJS supports ES6 or not, because my app is in ES6.

Which PhantomJS version do you use? Please register to the onConsoleMessage, onError, onResourceError, onResourceTimeout events (Example). Maybe there are errors. – Artjom B. Commented Jun 4, 2016 at 13:03
@ArtjomB. I am using phantomjs version 1.9.0. Am using the script from github./liuwenchao/ajax-seo/blob/master/seo.js – drishti ahuja Commented Jun 4, 2016 at 13:35
@ArtjomB. Even after adding onConsoleMessage, onError and other methods specified by you, not getting any error. Simply getting the output as before – drishti ahuja Commented Jun 4, 2016 at 13:39
