Neon is a library for creating cross-platform user interfaces that run everywhere on native runtime!

Neon unique characteristics:

• Bare metal/native, no intermediate/embedded runtime - which allow Neon easily target devices like: IoT, smartWatch where embedded runtime e.g Javascript is too expensive to afford.
• Instead of using Virtual DOM or Runtime Diffing, Neon generate/optimize its templates at Compile Time (like Svelte) and updates them with fine-grained reactions (like SolidJS) for the best performance.
• Neon use Haxe language/syntax - part of ECMAScript family, Javascript developer would find it extremely familiar, like home.

At a Glance:

package myApp;

import js.Browser.document;
import neon.platform.browser.Renderer;
import neon.core.Common;
import neon.core.Style;
import neon.core.State;

class Main {
    public static function main() {
        render(document.body, App, {name: "My App"});
    }
}

typedef AppProps = {
    var name:String;
};

var App = createComponent(function(props:AppProps) {
    var count = createSignal(0);
    var doubleCount = function() {
        return count.get() * 2;
    }

    var handleClick = function() {
        count.set(count.get() + 1);
    }

    return createElement("div", {style: styles.container}, [
        createElement("h1", {}, [
            "welcome ", props.name,
        ]),
        createElement("h2", {click: handleClick}, [
            "counter is: ", count.get(),
        ]),
        createElement("h2", {}, [
            "doubleCount is: ", doubleCount(),
        ]),
    ]);
});

var styles = createStyle({
    container: {
        color: "red",
        userSelect: "none",
        "@media (max-width: 768px)": {
            color: "green",
        }
    },
});

Platform support status:

• Browser
• Server side rendering, including Node.js (good for portable runtime like AWS Lambda Edge), and also include C++ target (offer blazing fast performance)
• macOS (POC implementation)
• Windows (POC implementation)
• Linux (POC implementation)
• iOS
• Android
• Other targets like VR/AR, smartWatch, smartTv, IoT devices..
