Mobile

This guide will cover concepts specific to the Dioxus mobile renderer.

Running Javascript

Dioxus provides some ergonomic wrappers over the browser API, but in some cases you may need to access parts of the browser API Dioxus does not expose.

For these cases, Dioxus desktop exposes the use_eval hook that allows you to run raw Javascript in the webview:

src/eval.rs
use dioxus::prelude::*;

fn main() {
    launch(app);
}

fn app() -> Element {
    let future = use_resource(move || async move {
        // You can create as many eval instances as you want
        let mut eval = document::eval(
            r#"
            // You can send messages from JavaScript to Rust with the dioxus.send function
            dioxus.send("Hi from JS!");
            // You can receive messages from Rust to JavaScript with the dioxus.recv function
            let msg = await dioxus.recv();
            console.log(msg);
            "#,
        );

        // You can send messages to JavaScript with the send method
        eval.send("Hi from Rust!").unwrap();

        // You can receive any message from JavaScript with the recv method
        eval.recv::<String>().await.unwrap()
    });

    match future.read_unchecked().as_ref() {
        Some(v) => rsx! {
            p { "{v}" }
        },
        _ => rsx! {
            p { "hello" }
        },
    }
}

Custom Assets

You can link to local assets in dioxus mobile instead of using a url:

src/eval.rs
use dioxus::prelude::*;

fn main() {
    launch(app);
}

fn app() -> Element {
    rsx! {
        div {
            img { src: "public/static/scanner.png" }
        }
    }
}

Integrating with Wry

In cases where you need more low level control over your window, you can use wry APIs exposed through the Desktop Config and the use_window hook
