# rust-fel
[](https://github.com/tostaylo/rust-fel/actions) [](https://github.com/tostaylo/rust-fel/issues) [](https://github.com/tostaylo/rust-fel/blob/master/LICENSE.txt) [](https://crates.io/crates/rust-fel) [](https://github.com/tostaylo/rust-fel/releases/tag/v0.1.0) [](https://docs.rs/rust-fel/0.1.0/rust_fel/)
An experimental front end library which relies on [rustwasm](https://github.com/rustwasm).
Very lightweight and does not support much of the [HTML Standard](https://html.spec.whatwg.org/). More work needs to be done to truly make this a viable option for creating client side front-ends with [rustwasm](https://github.com/rustwasm).
A working example can be found here [rust-fel-example](https://github.com/tostaylo/rust-fel-example)
## Features
- State Management
- [JSX](https://github.com/facebook/jsx) -like syntax
- [DOM](https://developer.mozilla.org/en-US/docs/Web/API/Document_Object_Model/Introduction) construction from a Virtual [DOM](https://developer.mozilla.org/en-US/docs/Web/API/Document_Object_Model/Introduction).
## Use
```
use crate::main_component::Main;
use wasm_bindgen::prelude::_;
extern crate rust_fel;
// invoked when the wasm module is instantiated
#[wasm_bindgen(start)]
pub fn main() -> Result<(), JsValue> {
let main = Main::create();
let app = rust_fel::App::new(main);
app.mount("root");
Ok(())
}
```
### Examples
A`rust_fel` [struct](https://doc.rust-lang.org/std/keyword.struct.html) component implements [rust_fel::Component](https://docs.rs/rust-fel/0.1.0/rust_fel/component/index.html)
