## Running examples locally
All local examples are built for the desktop renderer. This means you can simply clone this repo and call `cargo run --example EXAMPLE_NAME`. To run non-desktop examples, checkout the example projects shown above.
## Why Dioxus and why Rust?
TypeScript is a fantastic addition to JavaScript, but it's still fundamentally JavaScript. TS code runs slightly slower, has tons of configuration options, and not every package is properly typed.

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

## Auto Conversion of the `Children` field

This means that during the render process, a newer version of `TitleCardProps` will never be compared with a previous version, saving some clock cycles.
## 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
#[derive(Props, PartialEq)]
struct TitleCardProps {
title: String,
}
fn TitleCard(cx: Scope<TitleCardProps>) -> Element {
cx.render(rsx!{
h1 { "{cx.props.title}" }
})

```rust
#[inline_props]
fn TitleCard(cx: Scope, title: String) -> Element {
cx.render(rsx!{
h1 { "{title}" }
})
}
```
Again, this macro is optional and should not be used by library authors since you have less fine-grained control over documentation and optionality.
However, it's great for quickly throwing together an app without dealing with *any* extra boilerplate.
## The `Scope` object
Though very similar to React, Dioxus is different in a few ways. Most notably, React components will not have a `Scope` parameter in the component declaration.

## Rendering Nothing
Sometimes, you don't want your component to return anything at all. In these cases, we can pass "None" into our bracket. However, Rust is not able to infer that our `None` corresponds to `Element` so we need to cast it appropriately:
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.
```rust
rsx!(cx, {None as Element} )
fn demo(cx: Scope) -> Element {
None
}
```
## Moving Forward:
In this chapter, we learned how to render different Elements from a Component depending on a condition. This is a very powerful building block to assemble complex User Interfaces!

# 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.
Here's some reading about declaring UI in React:

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.

However, they internally translate their snake_case convention to HTML's camelCase convention. 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.
```rust
// settings.json
{
"rust-analyzer.diagnostics.disabled": [
"macro-error"
],
}
```
## 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.

# 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:
![Published App](../images/publish.png)
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.
