Hydration for create_server_action?

[y-haidar]

Hi I have been playing around with leptos and loved the Progressive Enhancement (and Graceful Degradation) concept, and so I have been trying to use ActionForms for all the inputs, but the downside that I noticed is that if a page is loaded, the action's value() will be empty until the wasm is loaded and then manually dispatch the action.

Is there a way to enable hydration/ssr for it? Am I missing something?

Bellow is sample code for what I am trying to do:

#[component]
pub fn MonthlyView(
  cx: Scope,
  data: RwSignal<Option<Result<Vec<(NaiveDate, Vec<String>)>, ServerFnError>>>,
) -> impl IntoView {
  // ...
}

// This included in the Router
#[component]
pub fn TestPage(cx: Scope) -> impl IntoView {
  let today = chrono::Utc::now().naive_utc().date();
  let test_action = create_server_action::<GetMonthlyView>(cx);

  // MonthlyView IS EMPTY until this runs(or user submits a request)
  test_action.dispatch(GetMonthlyView {
    year: today.year() as u32,
    month: today.month(),
  });

  view! { cx,
    <YearMonthInput action=test_action/>
    <MonthlyView data=test_action.value()/>
  }
}

The YearMonthInput component basically contains the ActionForm.

If you ever find yourself creating an action and immediately dispatching it, you should probably be using a resource instead. If you used a resource to load the data here, it would load on the server and stream down to the client. Any data you used from it in your view behind a Suspense or Transition would appear in the HTML before the WASM had loaded.

You could then use a create_effect and Resource::set to feed the action's value into the resource.

Worked perfectly, didn't know about the Resource::set. I was using a resource initially, but only figured how to change it via signals.

Also love your work thank you for leptos :)

Also a regular <Form method="GET ...> ... </Form> and a resource with use_query_map as oppose to create_signal was what I wanted, no create_server_action is needed. I am clearly not a forntend guy
