JSPM

Build web components using a syntax similar to React JS. 🚀

1. Scalable and reusable interfaces: Build once with Atomico, run anywhere — React, Vue, Svelte, HTML, WebView, you name it. Feels super simple — especially if you already know React. 🚀
2. Open communication: Atomico makes building and using web components easy — delivering a truly authentic dev experience. ⚡
3. Performance: Atomico is fast — actually 60% faster than React. Your apps will fly! 🚀

Atomico is fully type-friendly — full autocomplete powered by your IDE, TypeScript, and AI. 🚀

import { c } from "atomico";

const MyComponent = c(
    ({ message }) => (
        <host>
            <h1>Helo {message}</h1>
        </host>
    ),
    {
        props: { message: String }
    }
);

customElements.define("my-component", MyComponent);

Summary

Atomico is a modern micro-library created by Matias Trujillo, aka @UpperCod , designed to simplify web component development. It replaces the need for classes and contexts with functions and scoped logic, supporting attributes, properties, methods, and events — making your components cleaner and easier to maintain.
