If I use ionic to build as a website, will Cordova plugins still work?

Hi all,

I had this vague impression that someone says if you use ionic to build as website(which looks quite like a mobile app), all those cordova plugins will not work. Is that true? How?

So now is it possible to use cordova plugins like cordova toast in this mobile-app-like-website? If it can ,how can I install this plugin or reference this in this mobile-app-like-website?

Some help would be much appreciated!
