Yew Framework - API Documentation

Yew is a modern Rust framework for creating multi-threaded front-end web apps using WebAssembly

• Features a macro for declaring interactive HTML with Rust expressions. Developers who have experience using JSX in React should feel quite at home when using Yew.
• Achieves high performance by minimizing DOM API calls for each page render and by making it easy to offload processing to background web workers.
• Supports JavaScript interoperability, allowing developers to leverage NPM packages and integrate with existing JavaScript applications.

Supported Targets

• wasm32-unknown-unknown

Important Notes

• Yew is not (yet) production ready but is great for side projects and internal tools

Example

use yew::prelude::*;

enum Msg {
AddOne,
}

struct Model {
link: ComponentLink<Self>,
value: i64,
}

impl Component for Model {
type Message = Msg;
type Properties = ();

fn create(_props: Self::Properties, link: ComponentLink<Self>) -> Self {
Self {
link,
value: 0,
}
}

fn update(&mut self, msg: Self::Message) -> ShouldRender {
match msg {
Msg::AddOne => {
self.value += 1;
true
}
}
}

fn change(&mut self, _props: Self::Properties) -> ShouldRender {
false
}

fn view(&self) -> Html {
html! {
<div>
<button onclick=self.link.callback(|_| Msg::AddOne)>{ "+1" }</button>
<p>{ self.value }</p>
</div>
}
}
}

# fn dont_execute() {
fn main() {
yew::start_app::<Model>();
}
# }
