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!

It's very important to add `dioxus` with the `desktop` feature for this example. The `dioxus` crate is a batteries-include crate that combines a bunch of utility crates together, ensuring compatibility of the most important parts of the ecosystem. Under the hood, the `dioxus` crate configures various renderers, hooks, debug tooling, and more. The `desktop` feature ensures the we only depend on the smallest set of required crates to compile and render.
If you system does not provide the `libappindicator3` library, like Debian/bullseye, you can enable the replacement `ayatana` with an additional flag:
```shell

$ cargo add dioxus --features desktop --features ayatana

//! Dioxus Desktop Renderer

//! # Desktop
//!
//! One of Dioxus' killer features is the ability to quickly build a native desktop app that looks and feels the same across platforms. Apps built with Dioxus are typically <5mb in size and use existing system resources, so they won't hog extreme amounts of RAM or memory.
//!
//! Dioxus Desktop is built off Tauri. Right now there aren't any Dioxus abstractions over keyboard shortcuts, menubar, handling, etc, so you'll want to leverage Tauri - mostly [Wry](http://github.com/tauri-apps/wry/) and [Tao](http://github.com/tauri-apps/tao)) directly. The next major release of Dioxus-Desktop will include components and hooks for notifications, global shortcuts, menubar, etc.
//!
//!
//! ## Getting Set up
//!
//! Getting Set up with Dioxus-Desktop is quite easy. Make sure you have Rust and Cargo installed, and then create a new project:
//!
//! ```shell
//! $ cargo new --bin demo
//! $ cd app
//! ```
//!
//! Add Dioxus with the `desktop` feature:
//!
//! ```shell
//! $ cargo add dioxus --features desktop
//! ```
//!
//! Edit your `main.rs`:

//! fn app(cx: Scope) -> Element {
//! cx.render(rsx!{
//! div {
//! "hello world!"
//! }
//! })

//! ```
//!
//!
//! To configure the webview, menubar, and other important desktop-specific features, checkout out some of the launch configuration in the [API reference](https://docs.rs/dioxus-desktop/).

Dioxus Desktop Renderer
Render the Dioxus VirtualDom using the platform's native WebView implementation.
# Desktop
One of Dioxus' killer features is the ability to quickly build a native desktop app that looks and feels the same across platforms. Apps built with Dioxus are typically <5mb in size and use existing system resources, so they won't hog extreme amounts of RAM or memory.
Dioxus Desktop is built off Tauri. Right now there aren't any Dioxus abstractions over keyboard shortcuts, menubar, handling, etc, so you'll want to leverage Tauri - mostly [Wry](http://github.com/tauri-apps/wry/) and [Tao](http://github.com/tauri-apps/tao)) directly. The next major release of Dioxus-Desktop will include components and hooks for notifications, global shortcuts, menubar, etc.
## Getting Set up
Getting Set up with Dioxus-Desktop is quite easy. Make sure you have Rust and Cargo installed, and then create a new project:
```shell
$ cargo new --bin demo
$ cd app
```
Add Dioxus with the `desktop` feature:
```shell
$ cargo add dioxus --features desktop
```
Edit your `main.rs`:
```rust
// main.rs
use dioxus::prelude::*;
fn main() {
dioxus::desktop::launch(app);
}
fn app(cx: Scope) -> Element {
cx.render(rsx!{
div {
"hello world!"
}
})
}
```
To configure the webview, menubar, and other important desktop-specific features, checkout out some of the launch configuration in the [API reference](https://docs.rs/dioxus-desktop/).
## Future Steps
Make sure to read the [Dioxus Guide](https://dioxuslabs.com/guide) if you already haven't!

-----
Fermi is a global state management solution for Dioxus that's as easy as `use_state`.
Inspired by atom-based state management solutions, all state in Fermi starts as an `atom`:
```rust
static NAME: Atom<&str> = |_| "Dioxus";
```
From anywhere in our app, we can read our the value of our atom:
```rust
fn NameCard(cx: Scope) -> Element {
let name = use_read(&cx, NAME);
cx.render(rsx!{ h1 { "Hello, {name}"} })
}
```
We can also set the value of our atom, also from anywhere in our app:
```rust
fn NameCard(cx: Scope) -> Element {
let set_name = use_set(&cx, NAME);
cx.render(rsx!{
button {
onclick: move |_| set_name("Fermi"),
"Set name to fermi"
}
})
}
```
It's that simple!
## Installation
Fermi is currently under construction, so you have to use the `master` branch to get started.
```rust
[depdencies]
fermi = { git = "https://github.com/dioxuslabs/fermi" }
```
## Running examples
The examples here use Dioxus Desktop to showcase their functionality. To run an example, use
```
$ cargo run --example EXAMPLE
```
## Features
Broadly our feature set to required to be released includes:
- [x] Support for Atoms
- [x] Support for AtomRef (for values that aren't clone)
- [ ] Support for Atom Families
- [ ] Support for memoized Selectors
- [ ] Support for memoized SelectorFamilies
- [ ] Support for UseFermiCallback for access to fermi from async

/// This is an upgraded form of [`use_future`] with an integrated channel system.
/// Specifically, the coroutine generated here comes with an [`UnboundedChannel`]
/// built into it - saving you the hassle of building your own.
///
/// Addititionally, coroutines are automatically injected as shared contexts, so
/// downstream components can tap into a coroutine's channel and send messages
/// into a singular async event loop.
///
/// This makes it effective for apps that need to interact with an event loop or

///
/// ## Global State
///
/// Typically, writing apps that handle concurrency properly can be difficult,
/// so the intention of this hook is to make it easy to join and poll async tasks
/// concurrently in a centralized place. You'll find that you can have much better
/// control over your app's state if you centralize your async actions, even under
/// the same concurrent context. This makes it easier to prevent undeseriable
/// states in your UI while various async tasks are already running.
///
/// This hook is especially powerful when combined with Fermi. We can store important
/// global data in a coroutine, and then access display-level values from the rest
/// of our app through atoms.
///
/// ## UseCallback instead
///
/// However, you must plan out your own concurrency and synchronization. If you
/// don't care about actions in your app being synchronized, you can use [`use_callback`]
/// hook to spawn multiple tasks and run them concurrently.
///
/// ## Example
///
/// ```rust, ignore
/// enum Action {
/// Start,
/// Stop,
/// }
///
/// let chat_client = use_coroutine(&cx, |rx: UnboundedReceiver<Action>| async move {

pub fn use_ref<'a, T: 'static>(cx: &'a ScopeState, f: impl FnOnce() -> T) -> &'a UseRef<T> {
/// `use_ref` is a key foundational hook for storing state in Dioxus.
///
/// It is different that `use_state` in that the value stored is not "immutable".
/// Instead, UseRef is designed to store larger values that will be mutated at will.
///
/// ## Writing Values
///
/// Generally, `use_ref` is just a wrapper around a RefCell that tracks mutable
/// writes through the `write` method. Whenever `write` is called, the component
/// that initialized the hook will be marked as "dirty".
///
/// ```rust
/// let val = use_ref(|| HashMap::<u32, String>::new());
///
/// // using `write` will give us a `RefMut` to the inner value, which we can call methods on
/// // This marks the component as "dirty"
/// val.write().insert(1, "hello".to_string());
/// ```
///
/// You can avoid this defualt behavior with `write_silent`
///
/// ```
/// // with `write_silent`, the component will not be re-rendered
/// val.write_silent().insert(2, "goodbye".to_string());
/// ```
///
/// ## Reading Values
///
/// To read values out of the refcell, you can use the `read` method which will retrun a `Ref`.
///
/// ```rust
/// let map: Ref<_> = val.read();
///
/// let item = map.get(&1);
/// ```
///
/// To get an &T out of the RefCell, you need to "reborrow" through the Ref:
///
/// ```rust
/// let read = val.read();
/// let map = &*read;
/// ```
///
/// ## Collections and iteration
///
/// A common usecase for `use_ref` is to store a large amount of data in a component.
/// Typically this will be a collection like a HashMap or a Vec. To create new
/// elements from the collection, we can use `read()` directly in our rsx!.
///
/// ```rust
/// rsx!{
/// val.read().iter().map(|(k, v)| {
/// rsx!{ key: "{k}", value: "{v}" }
/// })
/// }
/// ```
///
/// If you are generating elements outside of `rsx!` then you might need to call
/// "render" inside the iterator. For some cases you might need to collect into
/// a temporary Vec.
///
/// ```rust
/// let items = val.read().iter().map(|(k, v)| {
/// cx.render(rsx!{ key: "{k}", value: "{v}" })
/// });
///
/// // collect into a Vec
///
/// let items: Vec<Element> = items.collect();
/// ```
///
/// ## Use in Async
///
/// To access values from a `UseRef` in an async context, you need to detach it
/// from the current scope's lifetime, making it a `'static` value. This is done
/// by simply calling `ToOnwed` or `Clone`.
///
/// ```rust
/// let val = use_ref(|| HashMap::<u32, String>::new());
///
/// cx.spawn({
/// let val = val.clone();
/// async move {
/// some_work().await;
/// val.write().insert(1, "hello".to_string());
/// }
/// })
/// ```
///
/// If you're working with lots of values like UseState and UseRef, you can use the
/// `clone!` macro to make it easier to write the above code.
///
/// ```rust
/// let val1 = use_ref(|| HashMap::<u32, String>::new());
/// let val2 = use_ref(|| HashMap::<u32, String>::new());
/// let val3 = use_ref(|| HashMap::<u32, String>::new());
///
/// cx.spawn({
/// clone![val1, val2, val3];
/// async move {
/// some_work().await;
/// val.write().insert(1, "hello".to_string());
/// }
/// })

//! Parse the root tokens in the rsx!{} macro
//! =========================================
//!
//! This parsing path emerges directly from the macro call, with `RsxRender` being the primary entrance into parsing.
//! This feature must support:
//! - [x] Optionally rendering if the `in XYZ` pattern is present
//! - [x] Fragments as top-level element (through ambiguous)
//! - [x] Components as top-level element (through ambiguous)
//! - [x] Tags as top-level elements (through ambiguous)
//! - [x] Good errors if parsing fails
//!
//! Any errors in using rsx! will likely occur when people start using it, so the first errors must be really helpful.
