# dioxus-core
|
|
|
|
`dioxus-core` provides a fast and featureful VirtualDom implementation for Rust.
|
|
|
|
```rust, no_run
|
|
# tokio::runtime::Runtime::new().unwrap().block_on(async {
|
|
use dioxus_core::prelude::*;
|
|
use dioxus_core::*;
|
|
|
|
let mut vdom = VirtualDom::new(app);
|
|
let real_dom = SomeRenderer::new();
|
|
|
|
loop {
|
|
tokio::select! {
|
|
evt = real_dom.event() => vdom.handle_event("onclick", evt, ElementId(0), true),
|
|
_ = vdom.wait_for_work() => {}
|
|
}
|
|
vdom.render_immediate(&mut real_dom.apply())
|
|
}
|
|
|
|
# fn app() -> Element { VNode::empty() }
|
|
# struct SomeRenderer; impl SomeRenderer { fn new() -> SomeRenderer { SomeRenderer } async fn event(&self) -> std::rc::Rc<dyn std::any::Any> { unimplemented!() } fn apply(&self) -> Mutations { Mutations::default() } }
|
|
# });
|
|
```
|
|

|
## Features
|
|
|
|
A virtualdom is an efficient and flexible tree data structure that allows you to manage state for a graphical user interface. The Dioxus VirtualDom is perhaps the most fully-featured virtualdom implementation in Rust and powers renderers running across Web, Desktop, Mobile, SSR, TUI, LiveView, and more. When you use the Dioxus VirtualDom, you immediately enable users of your renderer to leverage the wide ecosystem of Dioxus components, hooks, and associated tooling.
|
|
|
|
Some features of `dioxus-core` include:
|
|
|
|
- UI components are just functions
|
|
- State is provided by hooks
|
|
- Deep integration with async
|
|
- Strong focus on performance
|
|
- Integrated hotreloading support
|
|
- Extensible system for UI elements and their attributes
|

## Understanding the implementation
|
|
|
|
`dioxus-core` is designed to be a lightweight crate that. It exposes a number of flexible primitives without being deeply concerned about the intracices of state management itself. We provide a number of useful abstractions built on these primitives in the `dioxus-hooks` crate as well as the `dioxus-signals` crate.
|
|
|
|
The important abstractions to understand are:
|
|
|
|
- The [`VirtualDom`]
|
|
- The [`Component`] and its [`Properties`]
|
|
- Handling events
|
|
- Working with async
|
|
- Suspense
|
|
|
|
## Usage
|
|
|
|
The `dioxus` crate exports the `rsx` macro which transforms a helpful, simpler syntax of Rust.
|
|
|
|
First, start with your app:
|
|
|
|
```rust
|
|
# use dioxus::dioxus_core::Mutations;
|
|
use dioxus::prelude::*;
|
|
|
|
// First, declare a root component
|
|
fn app() -> Element {
|
|
rsx!{
|
|
div { "hello world" }
|
|
}
|
|
}
|
|
|
|
fn main() {
|
|
// Next, create a new VirtualDom using this app as the root component.
|
|
let mut dom = VirtualDom::new(app);
|
|
|
|
// The initial render of the dom will generate a stream of edits for the real dom to apply
|
|
let mutations = dom.rebuild_to_vec();
|
|
}
|
|
```
