I would like to develop a web application with Spring Boot, Spring Web MVC and Thymeleaf. I recently stumbled upon Web Components and Polymer which might be a good addition to Thymeleaf in order to use cool components. As I'm a frontend noob, I ask myself why I need this npm and bower stuff in order to use Polymer.
If I got it right, Web Components and Polymer are just js libraries. Why can't I just include them (maybe by using a cdn) in my html page? I like Thymeleaf as it's possible to view the pages without the need to have a webserver. If I could just include polymer as js library that would still work. I am quite sure that I misunderstand some major concepts, but I can't grab it. Can anyone help me?
Thanks!
