CSTK

CSTK is the "Classic Stylesheets Toolkit". It's intended as both a simple and (hopefully) performant JSX-based frontend TypeScript library based on reactive programming, and a set of widgets, layouts and utilities for building traditional desktop GUIs for the web.

Status

CSTK is still in the early experimental stages of development and may change or be abandoned at any time.

Reactivity

const a = bind(1);
const b = bind(2);
const c = zipWith([a, b], (a, b) => a + b);
console.log(c.value); // 3
a.value = 10
console.log(c.value); // 12

function Counter() {
    const count = bind(0);
    return <div>
        <button onClick={() => count.value++}>
            Increment
        </button>
        <div>The count is {count}</div>
    </div>;
}

Examples

• Counter (7GUIs)
• Temperature Converter (7GUIs)

How to use

Components

import { createElement, mount} from 'cstk';

// A component without inputs
function HelloWorld() {
    return <div>Hello, World!</div>;
}

// A component with a required input
function HelloName({name}: {
    name: string,
}) {
    return <div>Hello, {name}!</div>;
}

// The main application component
function App() {
    return <div>
        <HelloWorld/>
        <HelloName name='CSTK'/>
    </div>;
}

// Attach application component to the body
mount(document.body, <App/>);
