<p>Build single-page applications that run in the browser with Dioxus. To run on the Web, your app must be compiled to WebAssembly and depend on the <code>dioxus</code> and <code>dioxus-web</code> crates.</p>
<p>A build of Dioxus for the web will be roughly equivalent to the size of a React build (70kb vs 65kb) but it will load significantly faster because <a href="https://hacks.mozilla.org/2018/01/making-webassembly-even-faster-firefoxs-new-streaming-and-tiering-compiler/">WebAssembly can be compiled as it is streamed</a>.</p>
<p>Examples:</p>
<ul>
<li><a href="https://github.com/DioxusLabs/example-projects/tree/master/todomvc">TodoMVC</a></li>
<li><a href="https://github.com/DioxusLabs/example-projects/tree/master/ecommerce-site">ECommerce</a></li>
</ul>
<p><a href="https://github.com/DioxusLabs/example-projects/blob/master/todomvc"><img src="https://github.com/DioxusLabs/example-projects/raw/master/todomvc/example.png" alt="TodoMVC example" /></a></p>
<blockquote>
<p>Note: Because of the limitations of Wasm, <a href="https://rustwasm.github.io/docs/book/reference/which-crates-work-with-wasm.html">not every crate will work</a> with your web apps, so you'll need to make sure that your crates work without native system calls (timers, IO, etc).</p>
</blockquote>
<h2 id="support"><a class="header" href="#support">Support</a></h2>
<p>The Web is the best-supported target platform for Dioxus.</p>
<ul>
<li>Because your app will be compiled to WASM you have access to browser APIs through <a href="https://rustwasm.github.io/docs/wasm-bindgen/introduction.html">wasm-bingen</a>.</li>
<li>Dioxus provides hydration to resume apps that are rendered on the server. See the <a href="fullstack.html">fullstack</a> getting started guide for more information.</li>
</ul>
<h2 id="tooling"><a class="header" href="#tooling">Tooling</a></h2>
<p>To develop your Dioxus app for the web, you'll need a tool to build and serve your assets. We recommend using <a href="https://github.com/DioxusLabs/cli">dioxus-cli</a> which includes a build system, Wasm optimization, a dev server, and support hot reloading:</p>
<pre><code class="language-shell">cargo install dioxus-cli
</code></pre>
<p>Make sure the <code>wasm32-unknown-unknown</code> target for rust is installed:</p>
<pre><code class="language-shell">rustup target add wasm32-unknown-unknown
</code></pre>
<h2 id="creating-a-project"><a class="header" href="#creating-a-project">Creating a Project</a></h2>
<p>Create a new crate:</p>
<pre><code class="language-shell">cargo new --bin demo
cd demo
</code></pre>
<p>Add Dioxus and the web renderer as dependencies (this will edit your <code>Cargo.toml</code>):</p>
<pre><code class="language-bash">cargo add dioxus
cargo add dioxus-web
</code></pre>
<p>Edit your <code>main.rs</code>:</p>
<pre><pre class="playground"><code class="language-rust edition2018">#![allow(non_snake_case)]
// import the prelude to get access to the `rsx!` macro and the `Scope` and `Element` types
use dioxus::prelude::*;

fn main() {
    // launch the web app
    dioxus_web::launch(App);
}

// create a component that renders a div with the text &quot;Hello, world!&quot;
fn App(cx: Scope) -&gt; Element {
    cx.render(rsx! {
        div {
            &quot;Hello, world!&quot;
        }
    })
}
</code></pre></pre>
<p>And to serve our app:</p>
<pre><code class="language-bash">dioxus serve
</code></pre>
