This commit adds subtree memoization to Dioxus. Subtree memoization is basically a compile-time step that drastically reduces the amount of work the diffing engine needs to do at runtime by extracting non-changing nodes out into a static "template." Templates are then understood by the various renderers in the ecosystem as a faster way of rendering the same items. For example, in the web, templates are simply a set of DOM Nodes created once and then cloned later. This is the same pattern frameworks like Lithtml and SolidJS use to achieve near-perfect performance. Subtree memoization adds an additional level of complexity to Dioxus. The RSX macro needs to be much smarter to identify changing/nonchanging nodes and generate a mapping between the Template and its runtime counterparts. This commit represents a working starter point for this work, adding support for templates for the web, desktop, liveview, ssr, and native-core renderers. In the future we will try to shrink code generation, generally improve performance, and simplify our implementation. |

Dioxus
Dioxus is a portable, performant, and ergonomic framework for building cross-platform user interfaces in 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 can be used to deliver webapps, desktop apps, static sites, mobile apps, TUI apps, liveview apps, and more. Dioxus is entirely renderer agnostic and can be used as platform for any renderer.
If you know React, then you already know Dioxus.
Unique features:
- Desktop apps running natively (no Electron!) in less than 10 lines of code.
- Incredibly ergonomic and powerful state management.
- Comprehensive inline documentation - hover and guides for all HTML elements, listeners, and events.
- Extremely memory efficient - 0 global allocations for steady-state components.
- Multi-channel asynchronous scheduler for first-class async support.
- And more! Read the full release post.

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.
By using Rust, we gain:
- Static types for every library
- Immutability by default
- A simple and intuitive module system
- Integrated documentation (
go to sourceactually goes to source) - Advanced pattern matching
- Clean, efficient, composable iterators
- Inline built-in unit/integration testing
- Best-in-class error handling
- Powerful and sane standard library
- Flexible macro system
- Access to
crates.io
Specifically, Dioxus provides us many other assurances:
- Proper use of immutable data structures
- Guaranteed error handling (so you can sleep easy at night not worrying about
cannot read property of undefined) - Native performance on mobile
- Direct access to system IO
And much more. Dioxus makes Rust apps just as fast to write as React apps, but affords more robustness, giving your frontend team greater confidence in making big changes in shorter time.
Why NOT Dioxus?
You shouldn't use Dioxus if:
- You don't like the React Hooks approach to frontend
- You need a no-std renderer
- You want to support browsers where Wasm or asm.js are not supported.
- You need a Send+Sync UI solution (Dioxus is not currently thread-safe)
Comparison with other Rust UI frameworks
Dioxus primarily emphasizes developer experience and familiarity with React principles.
- Yew: prefers the elm pattern instead, no borrowed props, supports SSR (no hydration), no direct desktop/mobile support.
- Percy: Supports SSR but with less emphasis on state management and event handling.
- Sycamore: VDOM-less using fine-grained reactivity, but no direct support for desktop/mobile.
- Dominator: Signal-based zero-cost alternative, less emphasis on community and docs.
- Azul: Fully native HTML/CSS renderer for desktop applications, no support for web/ssr
Parity with React & Roadmap
Dioxus is heavily inspired by React, but we want your transition to feel like an upgrade. Dioxus is most of the way there, but missing a few key features. These include:
- 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
