+
+- Portals
+- Suspense integration with SSR
+- Server Components / Bundle Splitting / Lazy
+
+Dioxus is unique in the Rust ecosystem in that it supports:
+
+- Components with props that borrow from their parent
+- Server-side-rendering with client-side hydration
+- Support for desktop applications

 Dioxus differs slightly from other UI virtual doms in some subtle ways due to its memory allocator.
 
-One important aspect to understand is how props are passed down from parent components to children. All "components" (custom user-made UI elements) are tightly allocated together in an arena. However, because props and hooks are generically typed, they are casted to any and allocated on the heap - not in the arena with the components.

However, because props and hooks are generically typed, they are casted to `Any` and allocated on the heap - not in the arena with the components.
 
 With this system, we try to be more efficient when leaving the component arena and entering the heap. By default, props are memoized between renders using COW and context. This makes props comparisons fast - done via ptr comparisons on the cow pointer. Because memoization is done by default, parent re-renders will _not_ cascade to children if the child's props did not change.

 For users of React: Dioxus knows *not* to memoize components that borrow property fields. By default, every component in Dioxus is memoized. This can be disabled by the presence of a non-`'static` borrow.

+Yes - *another* macro! However, this one is entirely optional.

+Coming from React, the `Scope` object might be confusing. In React, you'll want to store data between renders with hooks. However, hooks rely on global variables which make them difficult to integrate in multi-tenant systems like server-rendering.
 
 In Dioxus, you are given an explicit `Scope` object to control how the component renders and stores data. The `Scope` object provides a handful of useful APIs for features like suspense, rendering, and more.

 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.
 
-> Note: Even though hooks are accessible, you should still prefer to one-way data flow and encapsulation. Your UI code should be as predictable as possible. Dioxus is plenty fast, even for the largest apps.

+
+Dioxus 是一个可移植、高性能的框架，用于在 Rust 中构建跨平台的用户界面。
+
+```rust
+fn app(cx: Scope) -> Element {
+    let mut count = use_state(&cx, || 0);
+
+    cx.render(rsx!(
+        h1 { "High-Five counter: {count}" }
+        button { onclick: move |_| count += 1, "Up high!" }
+        button { onclick: move |_| count -= 1, "Down low!" }
+    ))
+}
+```
+
+Dioxus 可用于制作 网页程序、桌面应用、静态站点、移动端应用。
+
+Dioxus 为不同的平台都提供了很好的开发文档。
+
+如果你会使用 React ，那 Dioxus 对你来说会很简单。 
+
+### 项目特点:
+- 对桌面应用的原生支持。
+- 强大的状态管理工具。
+- 支持所有 HTML 标签，监听器和事件。
+- 超高的内存使用率，稳定的组件分配器。
+- 多通道异步调度器，超强的异步支持。
+- 更多信息请查阅： [版本发布文档](https://dioxuslabs.com/blog/introducing-dioxus/).
+
+### 示例
+
+本项目中的所有例子都是 `桌面应用` 程序，请使用 `cargo run --example XYZ` 运行这些例子。

+## 为什么使用 Dioxus 和 Rust ？
+
+TypeScript 是一个不错的 JavaScript 拓展集，但它仍然算是 JavaScript。
+
+TS 代码运行效率不高，而且有大量的配置项。
+
+相比之下，Dioxus 使用 Rust 编写将大大的提高效能。
+
+使用 Rust 开发，我们能获得：
+
+- 静态类型支持。
+- 变量默认不变性。
+- 简单直观的模块系统。
+- 内部集成的文档系统。
+- 先进的模式匹配系统。
+- 简洁、高效、强大的迭代器。
+- 内置的 单元测试 / 集成测试。
+- 优秀的异常处理系统。
+- 强大且健全的标准库。
+- 灵活的 `宏` 系统。
+- 使用 `crates.io` 管理包。
+
+Dioxus 能为开发者提供的：
+
+- 安全使用数据结构。
+- 安全的错误处理结果。
+- 拥有原生移动端的性能。
+- 直接访问系统的IO层。
+
+Dioxus 使 Rust 应用程序的编写速度和 React 应用程序一样快，但提供了更多的健壮性，让团队能在更短的时间内做出强大功能。
+
+### 不建议使用 Dioxus 的情况？
+
+您不该在这些情况下使用 Dioxus ：
+
+- 您不喜欢类似 React 的开发风格。
+- 您需要一个 `no-std` 的渲染器。
+- 您希望应用运行在 `不支持 Wasm 或 asm.js` 的浏览器。
+- 您需要一个 `Send + Sync` UI 解决方案（目前不支持）。

+In React, "suspense" is the ability render nodes outside of the traditional lifecycle. React will wait on a future to complete, and once the data is ready, will render those nodes. React's version of suspense is designed to make working with promises in components easier.
 
 
 In Dioxus, we have similar philosophy, but the use and details of suspense is slightly different. For starters, we don't currently allow using futures in the element structure. Technically, we can allow futures - and we do with "Signals" - but the "suspense" feature itself is meant to be self-contained within a single component. This forces you to handle all the loading states within your component, instead of outside the component, keeping things a bit more containerized.

-/// Store state between component renders!
-///
-/// ## Dioxus equivalent of useState, designed for Rust
-///
-/// The Dioxus version of `useState` for state management inside components. It allows you to ergonomically store and
-/// modify state between component renders. When the state is updated, the component will re-render.
-///
-/// Dioxus' use_state basically wraps a RefCell with helper methods and integrates it with the VirtualDOM update system.
-///
-/// [`use_state`] exposes a few helper methods to modify the underlying state:
-/// - `.set(new)` allows you to override the "work in progress" value with a new value
-/// - `.get_mut()` allows you to modify the WIP value
-/// - `.get_wip()` allows you to access the WIP value
-/// - `.deref()` provides the previous value (often done implicitly, though a manual dereference with `*` might be required)
-///
-/// Additionally, a ton of std::ops traits are implemented for the `UseState` wrapper, meaning any mutative type operations
-/// will automatically be called on the WIP value.
-///
-/// ## Combinators
-///
-/// On top of the methods to set/get state, `use_state` also supports fancy combinators to extend its functionality:
-/// - `.classic()` and `.split()`  convert the hook into the classic React-style hook
-///     ```rust
-///     let (state, set_state) = use_state(&cx, || 10).split()
-///     ```
-///
-///
-/// Usage:
-///
-/// ```ignore
-/// const Example: Component = |cx| {
-///     let counter = use_state(&cx, || 0);
-///
-///     cx.render(rsx! {
-///         div {
-///             h1 { "Counter: {counter}" }
-///             button { onclick: move |_| counter += 1, "Increment" }
-///             button { onclick: move |_| counter -= 1, "Decrement" }
-///         }
-///     ))

 ## How to work around it:
 If an attribute in Dioxus is invalid (defined incorrectly) - first, make an issue - but then, you can work around it. The raw builder API is actually somewhat ergonomic to work with, and the NodeFactory type exposes a bunch of methods to make any type of tree - even invalid ones! So obviously, be careful, but there's basically anything you can do.

+# JS Interpreter
+
+After diffing old and new trees, the Dioxus VirtualDom produces patches that are used to modify the existing Dom. We can send these patches anywhere - including targets without WASM support.
+
+In renderers with support for JavaScript, we use the interpreter from this repository - written in TypeScript - to patch the Dom. This lets us circumvent any overhead on the Rust <-> Dom boundary and keep consistency in our interpreter implementation in web/webview targets.
+
+
+For now - both Dioxus Web and Dioxus Desktop (webview) use the same interpreter code with tweaks.
