I have a web project build on angular 6. Now, I want to extend it for mobile apps(both android and ios) using nativescript. I have done the basic setup to convert it. But it requires to rewrite the entire code for html & css part for mobile apps. It will be very time consuming as I am new to nativescript and there's a lot of html. I want to know, if there is any way to convert or sync automatically web html to native app html? if yes, what are those?
