maomi: a rust framework for building pages with components

This is the DOM binding module of the framework.

Quick Start

Pages are composed by components.

To build a page, write a component which contains the page content.

use wasm_bindgen::prelude::*;
use maomi::prelude::*;
use maomi_dom::{prelude::*, element::*};

// declare a component
#[component(Backend = DomBackend)]
struct HelloWorld {
    // a component should have a template field
    template: template! {
        <div>
            // text in the template must be quoted
            "Hello world!"
        </div>
    },
}

// the component must implement `Component` trait
impl Component for HelloWorld {
    fn new() -> Self {
        Self {
            template: Default::default(),
        }
    }
}

#[wasm_bindgen(start)]
pub fn wasm_main() {
    // the `<body>` is used to contain component content
    let dom_backend = DomBackend::new_with_document_body().unwrap();
    let backend_context = maomi::BackendContext::new(dom_backend);

    // create a mount point
    let mount_point = backend_context
        .enter_sync(move |ctx| {
            ctx.attach(|_: &mut HelloWorld| {}).unwrap()
        })
        .map_err(|_| "Cannot init mount point")
        .unwrap();

    // leak the backend context, so that event callbacks still work
    std::mem::forget(mount_point);
    std::mem::forget(backend_context);
}
