• run: template agnostic package to create an unidirectional user interface architecture
• router: hyperfun plugin to integrate a router in your hyperfun applications
• dom: Hyper Script Helpers and Incremental DOM/String mixed to create a template engine that can be rendered on the server and the client
• component: designed to be used in those cases when is needed to re-render a part of the app or when an action has to be executed in the life cycle. It uses Incremental DOM as a dependency to render and update the DOM tree

Example:

import { run, update } from '@hyperfun/run';
import { h1, li, p, patch, ul } from '@hyperfun/dom';

/* Types */

interface CounterState {
    counter: number;
}

/* State */

const state: CounterState = {
    counter: 0
};

/* Update */

const increment = () =>
    update({
        type: 'INCREMENT_COUNTER',
        payload: (state: State) => ({ counter: state.counter + 1 }),
    });
const decrement = () =>
    update({
        type: 'DECREMENT_COUNTER',
        payload: (state: State) => ({ counter: state.counter - 1 }),
    });
const reset = () =>
    update({
        type: 'RESET_COUNTER',
        payload: () => ({ counter: 0 }),
    });

/* View */

const counter = (state: CounterState) => p([state.counter]);

const view: View = (state: CounterState) =>
    section([
        counter(state),
        ul([
            li([button({ onClick: increment }, 'Increase')]),
            li([button({ onClick: decrement }, 'Decrement')]),
            li([button({ onClick: reset }, 'Reset')]),
        ])
    ]);

/* Render */

const render = (element, options) =>
    patch(options.element ? options.element() : document.getElementById('app'), element);

/* Run */

run({
    view,
    render,
    state
});
