How to work with "Lazy loading paths"?

Question

Vue.js

Hello.
I am creating a SPA application and I can’t figure out a bit with templates:c
I don’t fully understand how to properly split the code, I read about “Lazy loading of paths” in the documentation for vue-router.
I have never worked with WebPack, so I have a vague idea of ​​what it is, how to use it when deploying,
etc. .
vue-router connected via cdn
Everything works fine, but I can't figure out how to properly split the code (So that all templates are not loaded at once).
