Ex: You can make a beautiful HTML web pages using tailwind or derivatives like daisyui.com, tailwinduikit.com,

But if you want fully minimize css/js, you have to use npm to build you web pages.

Now my original question is how you going to take this npm/node base project to your DJango/rails/Java Spring project.

By partial rendering mean not using React/Vue type SSR, but rendering page snippets with HTMx,Jquery or plain JS.
