|
||
<p>O Dioxus 'VirtualDom' pode ser renderizado por servidor.</p>
|
||
<p><a href="https://github.com/dioxusLabs/docsite">Exemplo: Dioxus DocSite</a></p>
|
||
<h2 id="suporte-a-multitarefas"><a class="header" href="#suporte-a-multitarefas">Suporte a Multitarefas</a></h2>
|
||
<p>O Dioxus <code>VirtualDom</code>, infelizmente, atualmente não é <code>Send</code>. Internamente, usamos um pouco de mutabilidade interior que não é <em>thread-safe</em>. Isso significa que você não pode usar Dioxus facilmente com a maioria dos frameworks da web como Tide, Rocket, Axum, etc.</p>
|
||
<p>Para resolver isso, você deve gerar um <code>VirtualDom</code> em seu próprio thread e se comunicar com ele por meio de canais.</p>
|
||
<p>Ao trabalhar com frameworks web que requerem <code>Send</code>, é possível renderizar um <code>VirtualDom</code> imediatamente para uma <code>String</code> – mas você não pode manter o <code>VirtualDom</code> em um ponto de espera. Para SSR de estado retido (essencialmente LiveView), você precisará criar um <em>pool</em> de <code>VirtualDoms</code>.</p>
|
||
<h2 id="configurar"><a class="header" href="#configurar">Configurar</a></h2>
|
||
<p>Se você quer apenas renderizar <code>rsx!</code> ou um VirtualDom para HTML, confira os documentos da API. É bem simples:</p>
|
||
<pre><pre class="playground"><code class="language-rust edition2018">
|
||
<span class="boring">#![allow(unused)]
|
||
</span><span class="boring">fn main() {
|
||
</span>// We can render VirtualDoms
|
||
let mut vdom = VirtualDom::new(app);
|
||
let _ = vdom.rebuild();
|
||
println!("{}", dioxus::ssr::render_vdom(&vdom));
|
||
|
||
// Or we can render rsx! calls directly
|
||
println!( "{}", dioxus::ssr::render_lazy(rsx! { h1 { "Hello, world!" } } );
|
||
<span class="boring">}
|
||
</span></code></pre></pre>
|
||
<p>No entanto, para este guia, vamos mostrar como usar Dioxus SSR com <code>Axum</code>.</p>
|
||
<p>Certifique-se de ter o Rust and Cargo instalado e, em seguida, crie um novo projeto:</p>
|
||
<pre><code class="language-shell">cargo new --bin demo
|
||
cd app
|
||
</code></pre>
|
||
<p>Adicione o Dioxus com o recurso <code>ssr</code>:</p>
|
||
<pre><code class="language-shell">cargo add dioxus
|
||
cargo add dioxus-ssr
|
||
</code></pre>
|
||
<p>Em seguida, adicione todas as dependências do Axum. Isso será diferente se você estiver usando um Web Framework diferente</p>
|
||
<pre><code>cargo add tokio --features full
|
||
cargo add axum
|
||
</code></pre>
|
||
<p>Suas dependências devem ficar mais ou menos assim:</p>
|
||
<pre><code class="language-toml">[dependencies]
|
||
axum = "0.4.5"
|
||
dioxus = { version = "*" }
|
||
dioxus-ssr = { version = "*" }
|
||
tokio = { version = "1.15.0", features = ["full"] }
|
||
</code></pre>
|
||
<p>Agora, configure seu aplicativo Axum para responder em um <em>endpoint</em>.</p>
|
||
<pre><pre class="playground"><code class="language-rust edition2018">use axum::{response::Html, routing::get, Router};
|
||
use dioxus::prelude::*;
|
||
|
||
#[tokio::main]
|
||
async fn main() {
|
||
let addr = std::net::SocketAddr::from(([127, 0, 0, 1], 3000));
|
||
println!("listening on http://{}", addr);
|
||
|
||
axum::Server::bind(&addr)
|
||
.serve(
|
||
Router::new()
|
||
.route("/", get(app_endpoint))
|
||
.into_make_service(),
|
||
)
|
||
.await
|
||
.unwrap();
|
||
}
|
||
</code></pre></pre>
|
||
<p>E, em seguida, adicione nosso <em>endpoint</em>. Podemos renderizar <code>rsx!</code> diretamente:</p>
|
||
<pre><pre class="playground"><code class="language-rust edition2018">
|
||
<span class="boring">#![allow(unused)]
|
||
</span><span class="boring">fn main() {
|
||
</span>async fn app_endpoint() -> Html<String> {
|
||
Html(dioxus_ssr::render_lazy(rsx! {
|
||
h1 { "hello world!" }
|
||
}))
|
||
}
|
||
<span class="boring">}
|
||
</span></code></pre></pre>
|
||
<p>Ou podemos renderizar <code>VirtualDoms</code>.</p>
|
||
<pre><pre class="playground"><code class="language-rust edition2018">
|
||
<span class="boring">#![allow(unused)]
|
||
</span><span class="boring">fn main() {
|
||
</span>async fn app_endpoint() -> Html<String> {
|
||
fn app(cx: Scope) -> Element {
|
||
cx.render(rsx!(h1 { "hello world" }))
|
||
}
|
||
let mut app = VirtualDom::new(app);
|
||
let _ = app.rebuild();
|
||
|
||
Html(dioxus_ssr::render_vdom(&app))
|
||
}
|
||
<span class="boring">}
|
||
</span></code></pre></pre>
|
||
<p>E é isso!</p>
|
||
<blockquote>
|
||
<p>Você pode notar que não pode manter o VirtualDom em um ponto de espera. Dioxus atualmente não é ThreadSafe, então <em>deve</em> permanecer no <em>thread</em> que iniciou. Estamos trabalhando para flexibilizar essa exigência.</p>
