Add <Redirect /> component

[Bechma]

Motivation

We need to increase the compatibility of SSR redirects from server functions:

Problem

With axum in the backend as an example, the redirects emitted from the server functions with an utility like leptos_axum::redirect(cx, path) makes a request in the browser, but it doesn't redirects in the application(wasm).

To accomplish that, we need to not do a redirect, but instead, create a Response case that handle that in the client. Something like:

let navigate = use_navigate(cx);
match msg {
...
  Ok(EditorResponse::Redirect) => navigate("/login", NavigateOptions::default()).unwrap(),
...
}

What we really want is to keep the redirect from the server fn(so in case there is no wasm or js, the redirect will still do his job) and handle it in the client.

Solution

A <Redirect /> component for the integrations:

• Axum
• Actix
