Sycamore is a _reactive_ library for creating web apps in **Rust** and **WebAssembly**.
```rust
#[component]
fn Hello<G: Html>(cx: Scope) -> View<G> {
view! { cx,
p { "Hello World!" }
}
}
```
- **Lightning Speed**: Sycamore harnesses the full power of [Rust](https://www.rust-lang.org/) via
[WebAssembly](https://webassembly.org/), giving you full control over performance.
- **Ergonomic and Intuitive**: Write code that feels natural. Everything is built on
[reactive primitives](https://sycamore-rs.netlify.app/docs/basics/reactivity) without a cumbersome
virtual DOM.
- **No JavaScript**: Had enough of JavaScript? So have we. Create apps using Sycamore without
touching a single line of JS.
## Documentation
Sycamore is extensively documented:
- [Getting Started](https://sycamore-rs.netlify.app/docs/getting_started/installation): How to write
your first Sycamore app.
- [Reactivity](https://sycamore-rs.netlify.app/docs/basics/reactivity): Find out how to use
Sycamore's powerful reactive primitives.
- [API Documentation](https://docs.rs/sycamore): rustdocs for the `sycamore` crate.

## Examples
Sycamore has many examples for your reference in the
[`examples/`](https://github.com/sycamore-rs/sycamore/tree/master/examples) directory. Be sure to
check them out!
### Viewing on `sycamore-rs.netlify.app`
All the examples are hosted under `sycamore-rs.netlify.app/examples/<example_name>` with
`<example_name>` being the name of the example you want to view. For instance, the `todomvc` example
is hosted on
[`sycamore-rs.netlify.app/examples/todomvc`](https://sycamore-rs.netlify.app/examples/todomvc).
### Building Locally
All the examples can also be built locally using [Trunk](https://trunkrs.dev). For instance, the
following command builds and serves the `todomvc` example:
```bash
cd examples/todomvc
trunk serve
```
Now open up `localhost:8080` in your browser to see "Hello World!".
## Perseus
[Perseus](https://github.com/arctic-hen7/perseus) is a fullstack framework built with Sycamore.
Think [NextJS](https://nextjs.org) or [SvelteKit](https://kit.svelte.dev) but with no JavaScript.
Everything from backend to frontend is built with pure Rust!
## Alternatives?
Don't think Sycamore is for you? Thankfully, there are plenty of alternatives!
- **[SolidJS](https://github.com/solidjs/solid): A declarative, efficient and flexible JavaScript
library for building user interfaces** <br /> Solid is a JavaScript library which greatly inspired
Sycamore. Many concepts such as fine-grained reactivity and components as factory functions were
borrowed from Solid. If you don't mind working with JavaScript (or TypeScript), go check it out!
- **[Yew](https://github.com/yewstack/yew): Rust / Wasm framework for building client web apps**
<br /> Yew was also a big inspiration for Sycamore. Yew employs a VDOM and has a MVU (Elm)
architecture. If you think that's for you, take a look!
- **[MoonZoon](https://github.com/MoonZoon/MoonZoon): Rust Fullstack Framework** <br /> MoonZoon
also champions the no VDOM paradigm and uses [dominator](https://github.com/Pauan/rust-dominator)
as its underlying DOM layer. MoonZoon is a fullstack framework making it easier to combine
frontend and backend code with minimal boilerplate.
