You've probably noticed that many elements in the `rsx!` and `html!` macros support on-hover documentation. The approach we take to custom elements means that the unit struct is created immediately where the element is used in the macro. When the macro is expanded, the doc comments still apply to the unit struct, giving tons of in-editor feedback, even inside a proc macro.

## The Problem
Why do people say state management is so difficult? What does it mean?
Generally, state management is the code you need to write to ensure that your app renders the *correct* content. If the user inputs a name, then you need to display the appropriate response – like alerts, validation, and disable/enable various elements on the page. Things can quickly become tricky if you need loading screens and cancellable tasks.

For the simplest of apps, all of your state can enter the app from the root props. This is common in server-side rendering – we can collect all of the required state *before* rendering the content.

For example, let's say we have a component that has two children:

Borrowed Props cannot be safely memoized. However, this is not a problem – Dioxus relies on the memoization of their parents to determine if they need to be rerendered.

With Coroutines, we can centralize our async logic. The `rx` parameter is an Channel that allows code external to the coroutine to send data *into* the coroutine. Instead of looping on an external service, we can loop on the channel itself, processing messages from within our app without needing to spawn a new future.

We can use `.value()` to get the result of the future. On the first run, since there's no data ready when the component loads, its value will be `None`. However, once the future is finished, the component will be re-rendered and the value will now be `Some(...)`, containing the return value of the closure.

However, we haven't talked about error handling at all in this guide! In this chapter, we'll cover some strategies in handling errors to ensure your app never crashes.
## The simplest – returning None
Astute observers might have noticed that `Element` is actually a type alias for `Option<VNode>`. You don't need to know what a `VNode` is, but it's important to recognize that we could actually return nothing at all:
```rust

Most attributes, when rendered, will be rendered exactly as the input you provided. However, some attributes are considered "boolean" attributes and just their presence determines whether they affect the output. For these attributes, a provided value of `"false"` will cause them to be removed from the target element.

Liveview allows apps to _run_ on the server and _render_ in the browser. It uses WebSockets to communicate between the server and the browser.
Examples:
- [Axum Example](https://github.com/DioxusLabs/dioxus/tree/master/packages/liveview/examples/axum.rs)
- [Salvo Example](https://github.com/DioxusLabs/dioxus/tree/master/packages/liveview/examples/salvo.rs)
- [Warp Example](https://github.com/DioxusLabs/dioxus/tree/master/packages/liveview/examples/warp.rs)
## Support
Liveview is currently limited in capability when compared to the Web platform. Liveview apps run on the server in a native thread. This means that browser APIs are not available, so rendering WebGL, Canvas, etc is not as easy as the Web. However, native system APIs are accessible, so streaming, WebSockets, filesystem, etc are all viable APIs.
## Setup

Dioxus is a *portable* toolkit, meaning the Core implementation can run anywhere with no platform-dependent linking. Unlike many other Rust frontend toolkits, Dioxus is not intrinsically linked to WebSys. In fact, every element and event listener can be swapped out at compile time. By default, Dioxus ships with the `html` feature enabled, but this can be disabled depending on your target renderer.

Para ajudar na construção de um DOM, o núcleo nativo fornece quatro `traits`: `State`, `ChildDepState`, `ParentDepState` e `NodeDepState` e uma estrutura `RealDom`. O `ChildDepState`, `ParentDepState` e `NodeDepState` fornecem uma maneira de descrever como algumas informações em um nó se relacionam com as de seus parentes. Ao fornecer como construir um único nó a partir de suas relações, o native-core derivará uma maneira de atualizar o estado de todos os nós para você com `#[derive(State)]`. Depois de ter um estado, você pode fornecê-lo como genérico ao `RealDom`. `RealDom` fornece todos os métodos para interagir e atualizar seu novo dom.

Many of the Rust UI frameworks are particularly difficult to work with. Even the ones branded as "ergonomic" are quite challenging to in comparison to TSX/JSX. With Dioxus, we've innovated on a number of Rust patterns to deliver a framework that is actually enjoyable to develop in.
For example, many Rust frameworks require you to clone your data in for *every* closure and handler you use. This can get really clumsy for large apps.

Dioxus is humbly built off the work done by [Dodrio](https://github.com/fitzgen/dodrio), a now-archived research project by fitzgen exploring the use of bump allocators in UI frameworks.
Dioxus is *substantially* more performant than many of the other Rust DOM-based UI libraries (Yew/Percy) and is *significantly* more performant than React - roughly competitive with InfernoJS. While not as performant as libraries like SolidJS/Sycamore, Dioxus imposes roughly a ~3% overhead over DOM patching, so it's *plenty* fast.

## Works on Desktop and Mobile
We’ve mentioned before that Dioxus works practically anywhere that Rust does. When running natively as a desktop or mobile app, your Dioxus code will run on its own thread, not inside of a web runtime. This means you can access hardware, file system, and platform APIs directly without needing to go through a shim layer. In our examples, we feature a [file explorer app](https://github.com/DioxusLabs/example-projects/tree/master/file-explorer) and [WiFi scanner app](https://github.com/DioxusLabs/example-projects/tree/master/wifi-scanner) where platform access occurs inside an asynchronous multithreaded coroutine. This solves the problem faced by React Native and other cross-platform toolkits where JavaScript apps incur a massive performance penalty with substantial maintenance overhead associated with platform API shims.
