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 🙏

Readme

OfflineSync.js

npm version GitHub stars License: MIT

OfflineSync.js es una librería escrita en TypeScript que permite a las aplicaciones web y móviles funcionar sin conexión a internet, almacenando datos localmente y sincronizándolos automáticamente con el servidor al recuperar la conectividad.

Ideal para aplicaciones educativas, médicas, logísticas o de telecomunicaciones donde la conexión es inestable.


Características principales

  • Detección automática de conexión/desconexión
  • Almacenamiento local en localStorage, sessionStorage o IndexedDB
  • Sincronización automática con APIs REST o Firebase
  • Resolución inteligente de conflictos
  • Eventos personalizables (onSync, onOffline, onOnline, etc.)
  • Compatible con navegadores modernos y entornos híbridos

Instalación

Con NPM

npm install offlinesyncjs

 ##como se usa
import { OfflineSync } from "offlinesyncjs";

const sync = new OfflineSync({
  endpoint: "https://jsonplaceholder.typicode.com/posts", // URL de tu servidor que vallas a ocupar
});

// Guardar datos localmente
sync.save({ title: "Offline Post", body: "Contenido local", userId: 1 });

// Sincronización manual
sync.syncNow();
// Escuchar eventos
sync.on("online", () => console.log("Conexión restablecida"));
sync.on("offline", () => console.log("Sin conexión"));
sync.on("synced", (data) => console.log("Datos sincronizados:", data));


//Ejemplo usando IndexedDB
import { OfflineSync, IndexedDBAdapter } from "offlinesyncjs";

const sync = new OfflineSync({
  endpoint: "https://api.tuapp.com/data",
  storage: new IndexedDBAdapter("OfflineDB"),
});

Ejemplo práctico en React
import React, { useEffect } from "react";
import { OfflineSync } from "offlinesyncjs";

export default function App() {
  const sync = new OfflineSync({ endpoint: "/api/posts" });

  useEffect(() => {
    sync.on("synced", () => alert("Datos sincronizados con el servidor!"));
  }, []);

  const handleSubmit = () => {
    sync.save({ title: "Nuevo post offline", body: "Guardado sin conexión" });
  };

  return (
    <button onClick={handleSubmit}>Guardar offline</button>
  );
}
