  139. <p>Build a standalone native desktop app that looks and feels the same across operating systems.</p>
  140. <p>Apps built with Dioxus are typically &lt;5mb in size and use existing system resources, so they won't hog extreme amounts of RAM or memory.</p>
  141. <p>Examples:</p>
  142. <ul>
  143. <li><a href="https://github.com/DioxusLabs/example-projects/blob/master/file-explorer">File Explorer</a></li>
  144. <li><a href="https://github.com/DioxusLabs/example-projects/blob/master/wifi-scanner">WiFi Scanner</a></li>
  145. </ul>
  146. <p><a href="https://github.com/DioxusLabs/example-projects/tree/master/file-explorer"><img src="https://raw.githubusercontent.com/DioxusLabs/example-projects/master/file-explorer/image.png" alt="File ExplorerExample" /></a></p>
  147. <h2 id="support"><a class="header" href="#support">Support</a></h2>
  148. <p>The desktop is a powerful target for Dioxus but is currently limited in capability when compared to the Web platform. Currently, desktop apps are rendered with the platform's WebView library, but your Rust code is running natively on a native thread. This means that browser APIs are <em>not</em> available, so rendering WebGL, Canvas, etc is not as easy as the Web. However, native system APIs <em>are</em> accessible, so streaming, WebSockets, filesystem, etc are all viable APIs. In the future, we plan to move to a custom web renderer-based DOM renderer with WGPU integrations.</p>
  149. <p>Dioxus Desktop is built off <a href="https://tauri.app/">Tauri</a>. Right now there aren't any Dioxus abstractions over the menubar, handling, etc, so you'll want to leverage Tauri – mostly <a href="http://github.com/tauri-apps/wry/">Wry</a> and <a href="http://github.com/tauri-apps/tao">Tao</a>) directly.</p>
  150. <h1 id="getting-started"><a class="header" href="#getting-started">Getting started</a></h1>
  151. <h2 id="platform-specific-dependencies"><a class="header" href="#platform-specific-dependencies">Platform-Specific Dependencies</a></h2>
  152. <p>Dioxus desktop renders through a web view. Depending on your platform, you might need to install some dependancies.</p>
  153. <h3 id="windows"><a class="header" href="#windows">Windows</a></h3>
  154. <p>Windows Desktop apps depend on WebView2 – a library that should be installed in all modern Windows distributions. If you have Edge installed, then Dioxus will work fine. If you <em>don't</em> have Webview2, <a href="https://developer.microsoft.com/en-us/microsoft-edge/webview2/">then you can install it through Microsoft</a>. MS provides 3 options:</p>
  155. <ol>
  156. <li>A tiny &quot;evergreen&quot; <em>bootstrapper</em> that fetches an installer from Microsoft's CDN</li>
  157. <li>A tiny <em>installer</em> that fetches Webview2 from Microsoft's CDN</li>
  158. <li>A statically linked version of Webview2 in your final binary for offline users</li>
  159. </ol>
  160. <p>For development purposes, use Option 1.</p>
  161. <h3 id="linux"><a class="header" href="#linux">Linux</a></h3>
  162. <p>Webview Linux apps require WebkitGtk. When distributing, this can be part of your dependency tree in your <code>.rpm</code> or <code>.deb</code>. However, likely, your users will already have WebkitGtk.</p>
  163. <pre><code class="language-bash">sudo apt install libwebkit2gtk-4.1-dev libgtk-3-dev libayatana-appindicator3-dev
  164. </code></pre>
  165. <p>When using Debian/bullseye <code>libappindicator3-dev</code> is no longer available but replaced by <code>libayatana-appindicator3-dev</code>.</p>
  166. <pre><code class="language-bash"># on Debian/bullseye use:
  167. sudo apt install libwebkit2gtk-4.1-dev libgtk-3-dev libayatana-appindicator3-dev
  168. </code></pre>
  169. <p>If you run into issues, make sure you have all the basics installed, as outlined in the <a href="https://tauri.studio/v1/guides/getting-started/prerequisites#setting-up-linux">Tauri docs</a>.</p>
  170. <h3 id="macos"><a class="header" href="#macos">MacOS</a></h3>
  171. <p>Currently – everything for macOS is built right in! However, you might run into an issue if you're using nightly Rust due to some permissions issues in our Tao dependency (which have been resolved but not published).</p>
  172. <h2 id="creating-a-project"><a class="header" href="#creating-a-project">Creating a Project</a></h2>
  173. <p>Create a new crate:</p>
  174. <pre><code class="language-shell">cargo new --bin demo
  175. cd demo
  176. </code></pre>
  177. <p>Add Dioxus and the desktop renderer as dependencies (this will edit your <code>Cargo.toml</code>):</p>
  178. <pre><code class="language-shell">cargo add dioxus
  179. cargo add dioxus-desktop
  180. </code></pre>
  181. <p>Edit your <code>main.rs</code>:</p>
  182. <pre><pre class="playground"><code class="language-rust edition2018">#![allow(non_snake_case)]
