Dioxus can be used to deliver webapps, desktop apps, static sites, liveview apps, mobile apps (WIP), and more. At its core, Dioxus is entirely renderer agnostic and has great documentation for creating new renderers for any platform.

In general, Dioxus and React share many functional similarities. If this guide is lacking in any general concept or an error message is confusing, React's documentation might be more helpful. We are dedicated to providing a *familiar* toolkit for UI in Rust, so we've chosen to follow in the footsteps of popular UI frameworks (React, Redux, etc). If you know React, then you already know Dioxus. If you don't know either, this guide will still help you!

# Tasks
|
||||
|
||||
All async code in Dioxus must be explicit and handled through Dioxus' task system.
|
||||
|
||||
In this chapter, we'll learn how to spawn new tasks through our `Scope`.
|
||||
|
||||
## Spawning a task
|
||||
|
||||
You can push any `'static` future into the Dioxus future queue by simply calling `cx.spawn` to spawn a task. Pushing a future returns a `TaskId` which can then be used to cancel the
|
||||
|
||||
```rust
|
||||
fn App(cx: Scope) -> Element {
|
||||
cx.spawn(async {
|
||||
let mut count = 0;
|
||||
loop {
|
||||
tokio::time::delay(std::instant::Duration::from_millis(500)).await;
|
||||
count += 1;
|
||||
println!("Current count is {}", count);
|
||||
}
|
||||
});
|
||||
|
||||
None
|
||||
}
|
||||
```
|
||||
|
||||
The future must be `'static` - so any values captured by the task must not carry any references to `cx`. All the Dioxus hooks have a method called `for_async` which will create a slightly more limited handle to the hook for you to use in your async code.
|
||||
|
||||
```rust
|
||||
fn App(cx: Scope) -> Element {
|
||||
let mut count = use_state(&cx, || 0);
|
||||
|
||||
let taskid = cx.spawn({
|
||||
let mut count = count.for_async();
|
||||
async {
|
||||
loop {
|
||||
tokio::time::delay(std::instant::Duration::from_millis(500)).await;
|
||||
count += 1;
|
||||
println!("Current count is {}", count);
|
||||
}
|
||||
}
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
The task will run in the background until it is completed.
|
||||
|
||||
> Note: `spawn` will always spawn a *new* future. You probably want to call it from a hook initializer instead of the main body of your component.
|
||||
|
||||
When bringing lots of values into your task, we provide the `for_async!` macro which will can `for_async` on all values passed in. For types that implement `ToOwned`, `for_async!` will simply call `ToOwned` for that value.
|
||||
|
||||
```rust
|
||||
fn App(cx: Scope) -> Element {
|
||||
let mut age = use_state(&cx, || 0);
|
||||
let mut name = use_state(&cx, || "Bob");
|
||||
let mut description = use_state(&cx, || "asd".to_string());
|
||||
|
||||
let taskid = cx.spawn({
|
||||
for_async![count, name, description]
|
||||
async { /* code that uses count/name/description */ }
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
## Details of Tasks
|
||||
|
||||
Calling `spawn` is *not* a hook and will *always* generate a new task. Make sure to only spawn tasks when you want to. You should *probably* not call `spawn` in the main body of your component, since a new task will be spawned on every render.
|
||||
|
||||
## Spawning Tokio Tasks (for multithreaded use cases)
|
||||
|
||||
Sometimes, you might want to spawn a background task that needs multiple threads or talk to hardware that might block your app code. In these cases, we can can directly spawn a `tokio task` from our future. For Dioxus-Desktop, your task will be spawned onto Tokio's Multithreaded runtime:
|
||||
|
||||
```rust
|
||||
cx.spawn({
|
||||
tokio::spawn(async {
|
||||
// some multithreaded work
|
||||
}).await;
|
||||
|
||||
tokio::spawn_blocking(|| {
|
||||
// some extremely blocking work
|
||||
}).await;
|
||||
|
||||
tokio::spawn_local(|| {
|
||||
// some !Send work
|
||||
}).await;
|
||||
})
|
||||
```
|
||||
|
||||
> Note: Tokio tasks must be `Send`. Most hooks are `Send` compatible, but if they aren't, then you can use `spawn_local` to spawn onto Dioxus-Desktop's `localset`.

# Working with Async
|
||||
|
||||
Not all apps you'll build can be self-contained with synchronous code. You'll often need to interact with file systems, network interfaces, hardware, or timers.
|
||||
|
||||
So far, we've only talked about building apps with synchronous code, so this chapter will focus integrating asynchronous code into your app.
|
||||
|
||||
|
||||
## The Runtime
|
||||
|
||||
By default, Dioxus-Desktop ships with the `Tokio` runtime and automatically sets everything up for you.
|
||||
|
||||
|
||||
|
||||
## Send/Sync
|
||||
Writing apps that deal with Send/Sync can be frustrating at times. Under the hood, Dioxus is not currently thread-safe, so any async code you write does *not* need to be `Send/Sync`. That means Cell/Rc/RefCell are all fair game.
|
||||
|
||||
|
||||
|
||||
All async code in your app is polled on a `LocalSet`, so any async code we w

# Handling Events
|
||||
|
||||
In the overview for this section, we mentioned how we can modify the state of our component by responding to user-generated events inside of event listeners.
|
||||
|
||||
In this section, we'll talk more about event listeners:
|
||||
- What events are available
|
||||
- Handling event data
|
||||
- Mutability in event listeners

# Suspense

Suspense in Dioxus is enabled through placeholder nodes.

## Auto Conversion of the `Children` field
|
||||
|
||||
This pattern can become tedious in some instances, so Dioxus actually performs an implicit conversion of any `rsx` calls inside components into `Elements` at the `children` field. This means you must explicitly declare if a component can take children.

||||

## The inline_props macro
|
||||
|
||||
Yes - *another* macro! However, this one is entirely optional.
|
||||
|
||||
For internal components, we provide the `inline_props` macro, which will let you embed your `Props` definition right into the function arguments of your component.
|
||||
|
||||
Our title card above would be transformed from:
|
||||
|
||||
```rust
|
||||

|
||||
struct TitleCardProps {
|
||||
title: String,
|

}

|

cx.render(rsx!{

h1 { "{cx.props.title}" }
|
||||
})
|
||||
}
|
||||
```
|
||||
|
||||
to:
|
||||
|
||||
```rust
|
||||
#[inline_props]
|
||||
fn TitleCard(cx: Scope, title: String) -> Element {
|
||||

h1 { "{title}" }

Sometimes, you don't want your component to return anything at all. Under the hood, the `Element` type is just an alias for `Option<VNode>`, so you can simply return `None`.

This can be helpful in certain patterns where you need to perform some logical side-effects but don't want to render anything.

# Core Topics
|
||||
|
||||
In this chapter, we'll cover some core topics on how Dioxus works and how to best leverage the features to build a beautiful, reactive app.
|
||||
|
||||
At a very high level, Dioxus is simply a Rust framework for _declaring_ user interfaces and _reacting_ to changes.
|
||||
|
||||
1) We declare what we want our user interface to look like given a state using Rust-based logic and control flow.
|
||||
2) We declare how we want our state to change when the user triggers an event.
|
||||
|
||||
## Declarative UI
|
||||
|
||||
Dioxus is a *declarative* framework. This means that instead of manually writing calls to "create element" and "set element background to red," we simply *declare* what we want the element to look like and let Dioxus handle the differences.
|
||||
|
||||
Let's pretend that we have a stoplight we need to control - it has a color state with red, yellow, and green as options.
|
||||
|
||||
|
||||
Using an imperative approach, we would have to manually declare each element and then handlers for advancing the stoplight.
|
||||
|
||||
```rust
|
||||
let container = Container::new();
|
||||
|
||||
let green_light = Light::new().color("green").enabled(true);
|
||||
let yellow_light = Light::new().color("yellow").enabled(false);
|
||||
let red_light = Light::new().color("red").enabled(false);
|
||||
container.push(green_light);
|
||||
container.push(yellow_light);
|
||||
container.push(red_light);
|
||||
|
||||
container.set_onclick(move |_| {
|
||||
if red_light.enabled() {
|
||||
red_light.set_enabled(false);
|
||||
green_light.set_enabled(true);
|
||||
} else if yellow_light.enabled() {
|
||||
yellow_light.set_enabled(false);
|
||||
red_light.set_enabled(true);
|
||||
} else if green_light.enabled() {
|
||||
green_light.set_enabled(false);
|
||||
yellow_light.set_enabled(true);
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
As the UI grows in scale, our logic to keep each element in the proper state would grow exponentially. This can become very unwieldy and lead to out-of-sync UIs that harm user experience.
|
||||
|
||||
Instead, with Dioxus, we *declare* what we want our UI to look like:
|
||||
|
||||
```rust
|
||||
let mut state = use_state(&cx, || "red");
|
||||
|
||||
cx.render(rsx!(
|
||||
Container {
|
||||
Light { color: "red", enabled: state == "red", }
|
||||
Light { color: "yellow", enabled: state == "yellow", }
|
||||
Light { color: "green", enabled: state == "green", }
|
||||
|
||||
onclick: move |_| {
|
||||
state.set(match *state {
|
||||
"green" => "yellow",
|
||||
"yellow" => "red",
|
||||
"red" => "green",
|
||||
})
|
||||
}
|
||||
}
|
||||
))
|
||||
```
|
||||
|
||||
Remember: this concept is not new! Many frameworks are declarative - with React being the most popular. Declarative frameworks tend to be much more enjoyable to work with than imperative frameworks.
|
||||

||||

Every Element in your User Interface will have some sort of properties that the renderer will use when drawing to the screen. These might inform the renderer if the component should be hidden, what its background color should be, or to give it a specific name or ID.

When using custom attributes, make sure the name of the attribute **exactly** matches what the renderer is expecting.

All element attributes must occur *before* child elements. The `rsx!` macro will throw an error if your child elements come before any of your attributes. If you don't see the error, try editing your Rust-Analyzer IDE setting to ignore macro-errors. This is a temporary workaround because Rust-Analyzer currently throws *two* errors instead of just the one we care about.

## Listeners
|
||||
|
||||
Listeners are a special type of Attribute that only accept functions. Listeners let us attach functionality to our Elements by running a provided closure whenever the specified Listener is triggered.
|
||||
|
||||
We'll cover listeners in more depth in the Listeners chapter, but for now, just know that every listener must start with the `on` keyword and can accept either a closure or an expression wrapped in curly braces.

Typically, immediate-mode GUIs are simpler to write but can slow down as more features, like styling, are added.

Many GUIs today are written in *Retained mode* - your code changes the data of the user interface but the renderer is responsible for actually drawing to the screen. In these cases, our GUI's state sticks around as the UI is rendered. To help accommodate retained mode GUIs, like the web browser, Dioxus provides a mechanism to keep state around.
|
||||
|

Dioxus, following in the footsteps of React, provides a "Reactive" model for you to design your UI. This model emphasizes one-way data flow and encapsulation. Essentially, your UI code should be as predictable as possible.

## Mechanics of Hooks
|
||||
In order to have state stick around between renders, Dioxus provides the `hook` through the `use_hook` API. This gives us a mutable reference to data returned from the initialization function.

# Managing State
|
||||
|
||||
Every app you'll build with Dioxus will have some sort of state that needs to be maintained and updated as your users interact with it. However, managing state can be particular challenging at times, and is frequently the source of bugs in many GUI frameworks.
|
||||
|
||||
In this chapter, we'll cover the various ways to manage state, the appropriate terminology, various patterns, and then take an overview

# Publishing

|
||||
Congrats! You've made your first Dioxus app that actually does some pretty cool stuff. This app uses your operating system's WebView library, so it's portable to be distributed for other platforms.
|
||||
|
||||
In this section, we'll cover how to bundle your app for macOS, Windows, and Linux.
|
||||
|
||||
|
||||
|
||||
## Install `cargo-bundle`
|
||||
|
||||
|
||||
The first thing we'll do is install [`cargo-bundle`](https://github.com/burtonageo/cargo-bundle). This extension to cargo will make it very easy to package our app for the various platforms.
|
||||
|
||||
According to the `cargo-bundle` github page,
|
||||
|
||||
|
||||
|
||||
*"cargo-bundle is a tool used to generate installers or app bundles for GUI executables built with cargo. It can create .app bundles for Mac OS X and iOS, .deb packages for Linux, and .msi installers for Windows (note however that iOS and Windows support is still experimental). Support for creating .rpm packages (for Linux) and .apk packages (for Android) is still pending."*
|
||||
|
||||
|
||||
To install, simply run
|
||||
|
||||
|
||||
`cargo install cargo-bundle`
|
||||
|
||||
## Setting up your project
|
||||
|
||||
|
||||
To get a project setup for bundling, we need to add some flags to our `Cargo.toml` file.
|
||||
|
||||
|
||||
```toml
|
||||
[package]
|
||||
name = "example"
|
||||
# ...other fields...
|
||||
|
||||
[package.metadata.bundle]
|
||||
name = "DogSearch"
|
||||
identifier = "com.dogs.dogsearch"
|
||||
version = "1.0.0"
|
||||
copyright = "Copyright (c) Jane Doe 2016. All rights reserved."
|
||||
category = "Developer Tool"
|
||||
short_description = "Easily search for Dog photos"
|
||||
long_description = """
|
||||
This app makes it quick and easy to browse photos of dogs from over 200 bree
|
||||
"""
|
||||
```
|
||||
|
||||
|
||||
## Building
|
||||
|
||||
Following cargo-bundle's instructions, we simply `cargo-bundle --release` to produce a final app with all the optimizations and assets builtin.
|
||||
|
||||
Once you've ran `cargo-bundle --release`, your app should be accessible in
|
||||
|
||||
`target/release/bundle/<platform>/`.
|
||||
|
||||
For example, a macOS app would look like this:
|
||||
|
||||
|
||||
|
||||
Nice! And it's only 4.8 Mb - extremely lean!! Because Dioxus leverages your platform's native WebView, Dioxus apps are extremely memory efficient and won't waste your battery.
|
||||
|
||||
> Note: not all CSS works the same on all platforms. Make sure to view your app's CSS on each platform - or web browser (Firefox, Chrome, Safari) before publishing.

## Overview
|
||||
|
||||
Dioxus SSR provides utilities to render Dioxus components to valid HTML. Once rendered, the HTML can be rehydrated client side or served from your web-server of choice.
|
||||
|
||||
```rust
|
||||
// Our app:
|
||||
const App: Component = |cx| rsx!(cx, div {"hello world!"});
|
||||
let app: Component = |cx| cx.render(rsx!(div {"hello world!"}));
|
||||
|
||||
// Build the virtualdom from our app
|
||||
let mut vdom = VirtualDOM::new(App);
|
||||
|
||||
// This runs components, lifecycles, etc. without needing a physical dom. Some features (like noderef) won't work.
|
||||
let mut vdom = VirtualDom::new(app);
|
||||
let _ = vdom.rebuild();
|
||||
|
||||
// Render the entire virtualdom from the root
|
||||
let text = dioxus::ssr::render_vdom(&vdom);
|
||||
assert_eq!(text, "<div>hello world!</div>")
|
||||
```
|
||||
|
||||
|
||||
## Basic Usage
|
||||
|
||||
The simplest example is to simply render some `rsx!` nodes to html. This can be done with the [`render_lazy`] api.
|
||||
|
||||
```rust
|
||||
let content = dioxus::ssr::render(rsx!{
|
||||
div {
|
||||
(0..5).map(|i| rsx!(
|
||||
"Number: {i}"
|
||||
))
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
## Rendering a VirtualDom
|
||||
|
||||
```rust
|
||||
let mut dom = VirtualDom::new(app);
|
||||
let _ = dom.rebuild();
|
||||
|
||||
let content = dioxus::ssr::render_vdom(&dom);
|
||||
```
|
||||
|
||||
## Configuring output
|
||||
It's possible to configure the output of the generated HTML.
|
||||
|
||||
```rust
|
||||
let content = dioxus::ssr::render_vdom(&dom, |config| config.pretty(true).prerender(true));
|
||||
```
|
||||
|
||||
## Usage as a writer
|
||||
|
||||
We provide the basic `SsrFormatter` object that implements `Display`, so you can integrate SSR into an existing string, or write directly to a file.
|
||||
|
||||
```rust
|
||||
use std::fmt::{Error, Write};
|
||||
|
||||
let mut buf = String::new();
|
||||
|
||||
let dom = VirtualDom::new(app);
|
||||
let _ = dom.rebuild();
|
||||
|
||||
let args = dioxus::ssr::formatter(dom, |config| config);
|
||||
buf.write_fmt!(format_args!("{}", args));
|
||||
```
|
||||
|
||||
## Configuration
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
## Usage in pre-rendering
|
||||
|
||||
This crate is particularly useful in pre-generating pages server-side and then selectively loading dioxus client-side to pick up the reactive elements.

//! This crate demonstrates how to implement a custom renderer for Dioxus VNodes via the `TextRenderer` renderer.

//! The `TextRenderer` consumes a Dioxus Virtual DOM, progresses its event queue, and renders the VNodes to a String.

//! While `VNode` supports "to_string" directly, it renders child components as the RSX! macro tokens. For custom components,

//! ## Elements & your first component
|
||||
//!
|
||||
//! To assemble UI trees with Diouxs, you need to use the `render` function on
|
||||
//! something called `LazyNodes`. To produce `LazyNodes`, you can use the `rsx!`
|
||||
//! macro or the NodeFactory API. For the most part, you want to use the `rsx!`
|
||||
//! macro.
|
||||
//!
|
||||
//! Any element in `rsx!` can have attributes, listeners, and children. For
|
||||
//! consistency, we force all attributes and listeners to be listed *before*
|
||||
//! children.
|
||||
//!
|
||||
//! ```rust
|
||||
//! let value = "123";
|
||||
//!
|
||||
//! rsx!(
|
||||
//! div {
|
||||
//! class: "my-class {value}", // <--- attribute
|
||||
//! onclick: move |_| log::info!("clicked!"), // <--- listener
|
||||
//! h1 { "hello world" }, // <--- child
|
||||
//! }
|
||||
//! )
|
||||
//! ```
|
||||
//!
|
||||
//! The rsx macro accepts attributes in "struct form" and then will parse the rest
|
||||
//! of the body as child elements and rust expressions. Any rust expression that
|
||||
//! implements `IntoIterator<Item = impl IntoVNode>` will be parsed as a child.
|
||||
//!
|
||||
//! ```rust
|
||||
//! rsx!(
|
||||
//! div {
|
||||
//! (0..10).map(|_| rsx!(span { "hello world" }))
|
||||
//! }
|
||||
//! )
|
||||
//!
|
||||
//! ```
|
||||
//!
|
||||
//! Used within components, the rsx! macro must be rendered into an `Element` with
|
||||
//! the `render` function on Scope.
|
||||
//!
|
||||
//! If we want to omit the boilerplate of `cx.render`, we can simply pass in
|
||||
//! `cx` as the first argument of rsx. This is sometimes useful when we need to
|
||||
//! render nodes in match statements.
|
||||
//!
|
||||
//! ```rust
|
||||
//! fn example(cx: Scope) -> Element {
|
||||
//!
|
||||
//! // both of these are equivalent
|
||||
//! cx.render(rsx!("hello world"))
|
||||
//!
|
||||
//! rsx!(cx, "hello world!")
|
||||
//! }
|
||||
//! ```
|
||||
//!
|
||||
//! Putting everything together, we can write a simple component that a list of
|
||||
//! elements:
|
||||
//!
|
||||
//! ```rust
|
||||
//! fn app(cx: Scope) -> Element {
|
||||
//! let name = "dave";
|
||||
//! cx.render(rsx!(
|

//! h1 { "Hello, {name}!" }
