javascript - About single page applications and routing

Question

For example, the documentation for single-page application routing written with Vue and Angular says that the server will ignore the content after # and needs to implement the function of the content after # on the client. I don’t understand the routing clearly, which means that it will be loaded from the server during initialization. All pages or components? Wouldn't it be heavy to load for the first time?

Hash routing, the server will indeed ignore the content after #, but this should have nothing to do with loading those pages and components. I have never written a single-page application using Vue and Angular, but I can directly implement routing-based code separation by using React-router with webpack. If I use webpack2, I can also dynamically import.
