As with elm, sauron follows the simplistic design of writing view code. //! //! ### Example //! ```rust,no_run //! use sauron::html::attributes::*; //! use sauron::html::events::*; //! use sauron::*; //! use sauron::Component; //! use sauron::Node; //! use sauron::Program; //! use sauron::Cmd; //! use wasm_bindgen::prelude::*; //! use log::*; //! //! #[derive(Debug, PartialEq, Clone)] //! pub enum Msg { //! Click, //! } //! //! pub struct App { //! click_count: u32, //! } //! //! impl App { //! pub fn new() -> Self { //! App { click_count: 0 } //! } //! } //! //! impl Component<Msg> for App { //! //! fn view(&self) -> Node<Msg> { //! div!( //! [class("some-class"), id("some-id"), attr("data-id", 1)], //! [ //! input!( //! [ //! class("client"), //! type_("button"), //! value("Click me!"), //! onclick(|_| { //! trace!("Button is clicked"); //! Msg::Click //! }), //! ], //! [], //! ), //! text!("Clicked: {}", self.click_count), //! ], //! ) //! } //! //! fn update(&mut self, msg: Msg) -> Cmd<Self, Msg> { //! trace!("App is updating from msg: {:?}", msg); //! match msg { //! Msg::Click => { //! self.click_count += 1; //! Cmd::none() //! } //! } //! } //! //! } //! //! #[wasm_bindgen(start)] //! pub fn main() { //! Program::mount_to_body(App::new()); //! } //! ``` //! index.html //! ```html //! <html> //! <head> //! <meta content="text/html;charset=utf-8" http-equiv="Content-Type"/> //! <title>Minimal sauron app</title> //! </head> //! <body> //! <script src='pkg/minimal.js'></script> //! <script type=module> //! window.wasm_bindgen('pkg/minimal_bg.wasm') //! .catch(console.error); //! </script> //! </body> //! </html> //! ``` //! //! **Note:** You need to use the nightly compiler with minimum version: rustc 1.37.0-nightly (17e62f77f 2019-07-01) //! //! Build using //! ```sh //! $> wasm-pack build --target no-modules //! ``` //! Look at the [examples](https://github.com/ivanceras/sauron/tree/master/examples) //! and the build script for the details. //! //! //! ### Prerequisite: //! //! ```sh //! cargo install wasm-pack //! cargo install basic-http-server //! ``` //! //! **Warning:** I repeat, You need to use the latest nightly compiler in order for this to work. //! //!
