Quick Start

HellaJS is unopinionated in terms of setup and architecture. All you need to do is install the core and dom packages in any project and have a mount element in your HTML.

npm install @hellajs/core @hellajs/dom

Then, somewhere in your HTML:

<div id="app"></div>

Now, somewhere in your project:

import { signal } from "@hellajs/core";
import { mount } from "@hellajs/dom";

const App = () => {
  const count = signal(0);

  return (
    <button onclick={() => count(count() + 1)}>{count}</button>
  );
};

mount(App, "#app");

You can now run your project and see the button that increments the count when clicked.

That’s all there is to it!
