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 🙏

Librería para comunicación entre app y iframe

Readme

@aaroncode/iframe-bridge

Librería para facilitar la comunicación segura entre una aplicación padre y un iframe usando postMessage.

Instalación

npm install @aaroncode/iframe-bridge

Uso básico

1. Agrega los elementos en tu HTML

<button id="openKycBtn">Abrir KYC</button>
<iframe id="kycIframe" style="display:none;width:600px;height:400px;"></iframe>
<div id="mensaje"></div>

2. Usa la librería en tu JS

Opción A: Busca el archivo index.js dentro de la carpeta node_modules/@aaroncode/iframe-bridge/dist/ Copia este archivo a tu proyecto (por ejemplo, al mismo nivel que tu archivo de ejemplo) y renómbralo si lo deseas.

import { KycIframeBridge } from "./index.js";


Opción B: Importando desde npm (con bundler)

import { KycIframeBridge } from "@aaroncode/iframe-bridge";

Opción C: Importando desde CDN (jsDelivr)

import { KycIframeBridge } from "https://cdn.jsdelivr.net/npm/@aaroncode/iframe-bridge/+esm";

Ejemplo de uso:


    
    const bridge = new KycIframeBridge({
    iframeId: "kycIframe",
    buttonId: "openKycBtn",
    allowedOrigins: ["http://localhost:45679"],
    iframeUrl: "http://localhost:45679/kyc",
    entity: {
        id: "usuario-123",
        apiKey: "api-key-xyz"
    },
    onExit: (data) => {
        document.getElementById("mensaje").textContent = "KYC cerrado: " + (data?.message || "");
    },
    onError: (data) => {
        document.getElementById("mensaje").textContent = "Error: " + (data?.message || "");
    }
    });

Opciones del constructor

| Opción | Tipo | Descripción | | -------------- | -------- | -------------------------------------------------- | | iframeId | string | ID del iframe en el DOM | | buttonId | string | ID del botón que abre el iframe | | allowedOrigins | string[] | Lista de orígenes permitidos para recibir mensajes | | iframeUrl | string | URL que se cargará en el iframe | | entity | object | Datos que se enviarán al iframe | | onExit | function | Callback al cerrar el iframe | | onError | function | Callback para errores |

Notas

  • Solo se permite comunicación por postMessage (no acceso directo al DOM del iframe si es cross-origin).
  • Si tienes una app sin usar herramientas de empaquetado la mejor forma es usando la libreria es descargandolo desde npm usando npm install @aaroncode/iframe-bridge luego buscar la carpeta dentro de node_modules el archivo index.js en la carpeta @aaroncode/iframe-bridge/dist/index.js y copear lo que existe en este archivo en un archivo js
