<p>This guide assumes you read the <a href="web.html">Web</a> guide and installed the <a href="https://github.com/DioxusLabs/cli">Dioxus-cli</a></p>
</blockquote>
<h1 id="getting-started"><a class="header" href="#getting-started">Getting Started</a></h1>
<h2 id="setup"><a class="header" href="#setup">Setup</a></h2>
<p>For this guide, we're going to show how to use Dioxus with <a href="https://docs.rs/axum/latest/axum/">Axum</a>, but <code>dioxus-fullstack</code> also integrates with the <a href="https://docs.rs/warp/latest/warp/">Warp</a> and <a href="https://docs.rs/salvo/latest/salvo/">Salvo</a> web frameworks.</p>
<p>Make sure you have Rust and Cargo installed, and then create a new project:</p>
<pre><code class="language-shell">cargo new --bin demo
cd demo
</code></pre>
<p>Add <code>dioxus</code> and <code>dioxus-fullstack</code> as dependencies:</p>
<pre><code class="language-shell">cargo add dioxus
cargo add dioxus-fullstack --features axum, ssr
</code></pre>
<p>Next, add all the Axum dependencies. This will be different if you're using a different Web Framework</p>
<pre><code class="language-shell">cargo add tokio --features full
cargo add axum
</code></pre>
<p>Your dependencies should look roughly like this:</p>
<pre><code class="language-toml">[dependencies]
axum = &quot;*&quot;
dioxus = { version = &quot;*&quot; }
dioxus-fullstack = { version = &quot;*&quot;, features = [&quot;axum&quot;, &quot;ssr&quot;] }
tokio = { version = &quot;*&quot;, features = [&quot;full&quot;] }
</code></pre>
<p>Now, set up your Axum app to serve the Dioxus app.</p>
<pre><pre class="playground"><code class="language-rust edition2018">#![allow(non_snake_case, unused)]
use dioxus::prelude::*;

#[tokio::main]
async fn main() {
    #[cfg(feature = &quot;ssr&quot;)]
    {
        use dioxus_fullstack::prelude::*;

        let addr = std::net::SocketAddr::from(([127, 0, 0, 1], 8080));
        axum::Server::bind(&amp;addr)
            .serve(
                axum::Router::new()
                    .serve_dioxus_application(&quot;&quot;, ServeConfigBuilder::new(app, ()))
                    .into_make_service(),
            )
            .await
            .unwrap();
    }
}

fn app(cx: Scope) -&gt; Element {
    let mut count = use_state(cx, || 0);

    cx.render(rsx! {
        h1 { &quot;High-Five counter: {count}&quot; }
        button { onclick: move |_| count += 1, &quot;Up high!&quot; }
        button { onclick: move |_| count -= 1, &quot;Down low!&quot; }
    })
}
</code></pre></pre>
<p>Now, run your app with <code>cargo run</code> and open <code>http://localhost:8080</code> in your browser. You should see a server-side rendered page with a counter.</p>
<h2 id="hydration"><a class="header" href="#hydration">Hydration</a></h2>
<p>Right now, the page is static. We can't interact with the buttons. To fix this, we can hydrate the page with <code>dioxus-web</code>.</p>
<p>First, modify your <code>Cargo.toml</code> to include two features, one for the server called <code>ssr</code>, and one for the client called <code>web</code>.</p>
<pre><code class="language-toml">[dependencies]
# Common dependancies
dioxus = { version = &quot;*&quot; }
dioxus-fullstack = { version = &quot;*&quot; }

# Web dependancies
dioxus-web = { version = &quot;*&quot;, features=[&quot;hydrate&quot;], optional = true }

# Server dependancies
axum = { version = &quot;0.6.12&quot;, optional = true }
tokio = { version = &quot;1.27.0&quot;, features = [&quot;full&quot;], optional = true }

[features]
default = []
ssr = [&quot;axum&quot;, &quot;tokio&quot;, &quot;dioxus-fullstack/axum&quot;]
web = [&quot;dioxus-web&quot;]
</code></pre>
<p>Next, we need to modify our <code>main.rs</code> to use either hydrate on the client or render on the server depending on the active features.</p>
<pre><pre class="playground"><code class="language-rust edition2018">#![allow(non_snake_case, unused)]
use dioxus::prelude::*;

fn main() {
    #[cfg(feature = &quot;web&quot;)]
    dioxus_web::launch_cfg(app, dioxus_web::Config::new().hydrate(true));
    #[cfg(feature = &quot;ssr&quot;)]
    {
        use dioxus_fullstack::prelude::*;
        tokio::runtime::Runtime::new()
            .unwrap()
            .block_on(async move {
                let addr = std::net::SocketAddr::from(([127, 0, 0, 1], 8080));
                axum::Server::bind(&amp;addr)
                    .serve(
                        axum::Router::new()
                            .serve_dioxus_application(&quot;&quot;, ServeConfigBuilder::new(app, ()))
                            .into_make_service(),
                    )
                    .await
                    .unwrap();
            });
    }
}

fn app(cx: Scope) -&gt; Element {
    let mut count = use_state(cx, || 0);

    cx.render(rsx! {
        h1 { &quot;High-Five counter: {count}&quot; }
        button { onclick: move |_| count += 1, &quot;Up high!&quot; }
        button { onclick: move |_| count -= 1, &quot;Down low!&quot; }
    })
}
</code></pre></pre>
<p>Now, build your client-side bundle with <code>dioxus build --features web</code> and run your server with <code>cargo run --features ssr</code>. You should see the same page as before, but now you can interact with the buttons!</p>
<h2 id="sycronizing-props-between-the-server-and-client"><a class="header" href="#sycronizing-props-between-the-server-and-client">Sycronizing props between the server and client</a></h2>
<p>Let's make the initial count of the counter dynamic based on the current page.</p>
<h3 id="modifying-the-server"><a class="header" href="#modifying-the-server">Modifying the server</a></h3>
<p>To do this, we must remove the serve_dioxus_application and replace it with a custom implementation of its four key functions:</p>
<ul>
<li>Serve static WASM and JS files with serve_static_assets</li>
<li>Register server functions with register_server_fns (more information on server functions later)</li>
<li>Connect to the hot reload server with connect_hot_reload</li>
<li>A custom route that uses SSRState to server-side render the application</li>
</ul>
<h3 id="modifying-the-client"><a class="header" href="#modifying-the-client">Modifying the client</a></h3>
<p>The only thing we need to change on the client is the props. <code>dioxus-fullstack</code> will automatically serialize the props it uses to server render the app and send them to the client. In the client section of <code>main.rs</code>, we need to add <code>get_root_props_from_document</code> to deserialize the props before we hydrate the app.</p>
