Server-side functions with non-empty response.

[veta666]

Hello!

First of all, thank you for your project, it makes work with web so more comfortable!

While I was reading leptos book, it was so easy to make client-side rendering. But in the end I've met some problems with server-side functions. In this chapter server function looks very easy, but it isn't returning something from server and spawn_local.. return (). But what if I need to ask server and receive some data back?

Look at the final section of the chapter you linked to, or at some of the examples in this repo that use server functions (like todo_app_sqlite):

Because a server function is just a plain Rust async function, it integrates perfectly with the async Leptos primitives we discussed earlier. So you can easily integrate your server functions with the rest of your applications:

• Create resources that call the server function to load data from the server
• Read these resources under or to enable streaming SSR and fallback states while data loads.

In other words, say you have a server function called my_server_function: just create a resource that calls it.

let async_data = create_resource(cx,
    || (),
    |_| my_server_function(),
);
