Latest Release: v0.9.2

use sycamore::prelude::*;

#[component]
fn Counter(initial: i32) -> View {
    let mut value = create_signal(initial);

    view! {
        button(on:click=move |_| value += 1) {
            "Count: " (value)
        }
    }
}

Features

Effortless Performance

Sycamore is built on top of Rust and WebAssembly, giving you full
control over performance.

Fine-Grained Reactivity

Sycamore's reactivity system is fine-grained, meaning that only the
parts of your app that need to be updated will be.

Type-checked UI

Whether you use our custom DSL or the builder API, Sycamore
type-checks your code to catch errors at compile-time.

Server Side Rendering (SSR)

Sycamore supports Server Side Rendering out of the box. If you don't
need it, however, SPA mode works just as well.

Async and Suspense

Easily load and display asynchronous data using the resources and
suspense API with first-class async/await support.

Built-in Routing

Sycamore comes with a built-in router that supports both client-side
navigation and server side rendering.
