The previous section described the process of server-side rendering, using the server to generate an HTML version of the page that will become interactive in the browser. So far, everything has been “isomorphic” or “universal”; in other words, your app has had the “same (iso) shape (morphe)” on the client and the server.
But a server can do a lot more than just render HTML! In fact, a server can do a whole bunch of things your browser can’t, like reading from and writing to a SQL database.
With Leptos, you can do both: not only in the same language, not only sharing the same types, but even in the same files!
This section will talk about how to build the uniquely-server-side parts of your application.
