Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

🍋 Papaya.js — Framework frontend reactivo, simple y sin build tools.

Readme

Papaya.js

Framework frontend reactivo, simple y sin build tools.


1. Introducción técnica

Papaya.js es un micro-framework frontend diseñado para desarrolladores que buscan comprender y aplicar los fundamentos de la reactividad y el renderizado declarativo sin depender de herramientas de compilación o entornos complejos.

Papaya combina simplicidad estructural, flujo de datos unidireccional y composición de componentes a través de módulos ES nativos, brindando una base sólida para el desarrollo de interfaces modernas con JavaScript puro.

Su propĂłsito no es competir con React, Vue o Svelte, sino ofrecer una alternativa educativa y funcional que demuestre cĂłmo funcionan internamente los frameworks modernos.


2. CaracterĂ­sticas clave

  • Reactividad minimalista basada en Proxy y watchers.
  • Renderizado declarativo mediante templates tagged (`html``...```).
  • Montaje automático con etiquetas <component src="...">.
  • Router nativo con soporte para rutas dinámicas (/user/:id).
  • Ciclo de vida (onMount, onDestroy) integrado en el nĂşcleo.
  • Arquitectura modular (runtime, template, router, core).
  • Sin dependencias, sin compiladores, sin configuraciones.
  • Tamaño total: ~4KB minificado.

3. Instalación y uso rápido

Opción 1 — CDN o local

<script type="module">
  import Papaya from "./dist/papaya.min.js";
  Papaya.mount();
</script>

Opción 2 — NPM

npm install @usercr1dev/papayajs
import Papaya from "@usercr1dev/papayajs";
Papaya.mount();

Estructura base

papaya/
├─ dist/
│  └─ papaya.min.js
├─ components/
│  └─ Welcome.js
├─ index.html
└─ main.js

4. Arquitectura conceptual

Papaya.js se compone de cuatro mĂłdulos principales:

| Módulo | Descripción | |--------|--------------| | runtime.js | Implementa el sistema reactivo (basado en Proxy y watch). | | template.js | Convierte templates HTML en fragmentos reactivos con actualización automática. | | router.js | Enrutador declarativo y ligero basado en el history API. | | papaya.js (core) | Punto de entrada público; expone la API global y gestiona el montaje automático de componentes. |


5. Principios de diseño

5.1 Unidirectional Data Flow

Papaya sigue un flujo de datos de una sola direcciĂłn. Las vistas derivan de un estado reactivo, y cualquier cambio en ese estado provoca una actualizaciĂłn controlada del DOM.

5.2 Declarative Rendering

El renderizado se realiza con plantillas declarativas (`html``...```) que vinculan datos reactivos sin manipulaciĂłn directa del DOM.

5.3 Minimal Abstraction Layers

Papaya evita capas innecesarias entre el cĂłdigo del desarrollador y el DOM, permitiendo comprender el flujo completo de datos y renderizado.


6. Ejemplo práctico

// components/Welcome.js
export default function Welcome() {
  const el = document.createElement("div");
  el.innerHTML = `
    <h1>Papaya.js</h1>
    <p>Framework frontend simple, reactivo y sin build tools.</p>
  `;
  return el;
}
<component src="./components/Welcome.js"></component>
<script type="module">
  import Papaya from "./dist/papaya.min.js";
  Papaya.mount();
</script>

7. Comparativa técnica (Papaya vs React)

| Concepto | Papaya.js | React | |-----------|------------|--------| | Lenguaje | JavaScript puro (ESM) | JSX + Babel | | Reactividad | Proxy nativo + watchers | Virtual DOM + diffing | | Tamaño | ~4KB | ~100KB | | Dependencias | Ninguna | Varias (React, ReactDOM) | | Build Tool | No requerido | Webpack / Vite | | Filosofía | Simplicidad y comprensión | Escalabilidad y ecosistema |


8. FilosofĂ­a Papaya.js

“Hazlo simple, hazlo entendible, hazlo Papayuca.”

Papaya.js promueve la comprensión sobre la abstracción. Cada línea de su core busca mostrar cómo un framework moderno puede construirse de forma transparente y didáctica, sin ocultar el funcionamiento interno.


9. Roadmap Técnico

| Versión | Estado | Objetivos | |----------|----------|------------| | 0.2.0 | ✅ Actual | Núcleo estable (reactividad, router, templates). | | 0.3.0 | 🚧 En desarrollo | Hooks, efectos, tipado, dev-server. | | 0.4.0 | 🧠 Planeado | SSR básico, compatibilidad TypeScript, CLI “papaya dev”. |

English Version

Papaya.js

Reactive frontend framework built with pure JavaScript — no build tools, no dependencies.

Overview

Papaya.js is a micro reactive framework for developers who want to understand modern frontend architecture without abstraction layers or build systems. It focuses on clarity, simplicity, and educational value while remaining fully functional for real projects.

Core Concepts

  • Reactive state via native Proxies.
  • Declarative DOM rendering via tagged templates.
  • Auto-mounting with <component src="...">.
  • Built-in router and lifecycle hooks.
  • Lightweight core (~4KB).

Architecture

Papaya consists of:

  • runtime.js: reactive core and dependency tracking.
  • template.js: HTML templates with reactive bindings.
  • router.js: client-side navigation with dynamic params.
  • papaya.js: public API and component auto-loader.

Design Principles

  • Unidirectional Data Flow
  • Declarative Rendering
  • Minimal Abstraction Layers

Example

<component src="./components/Welcome.js"></component>
<script type="module">
  import Papaya from "./dist/papaya.min.js";
  Papaya.mount();
</script>

Philosophy

“Keep it simple, keep it clear.”
Papaya.js demonstrates how reactivity and declarative UIs can exist without complexity — making it an ideal learning and prototyping framework.
