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 🙏

Kilden web SDK: analytics, identity, autocapture and session replay on the shared data foundation

Readme

kilden-sdk-js

SDK web de Kilden. TypeScript estricto, cero dependencias de runtime, builds ESM + CJS + IIFE (el snippet carga el IIFE). Contexto general en el CLAUDE.md del wrapper padre; superficie y contratos congelados en ../docs/10-sdk-api.md (y en el CLAUDE.md de este repo).

Uso

import kilden from 'kilden';               // singleton
kilden.init('wk_...', { debug: true });
kilden.track('signup_completed', { plan: 'pro' });
kilden.identify('user-42', { name: 'Ada' });

// o la primitiva real, sin singleton:
import { createClient } from 'kilden';
const client = createClient('wk_...', { autocapture: false });

Para sitios sin bundler: snippet.html (loader async con cola de stubs — las llamadas hechas antes de que cargue el bundle no se pierden y se reproducen en orden).

Arquitectura

El core es: cola + identidad + transporte + pipeline de plugins (before → enrichment → after, ver ../docs/13-sdk-plugins.md). Todo lo demás son plugins — incluidas las features propias: sesiones, contexto, $utm_* (plugins internos) y autocapture (plugin en chunk lazy: con autocapture: false nunca se descarga). beforeSend es azúcar sobre un plugin before.

La superficie de session replay (startSessionRecording, etc.) y group() están reservadas: no-op con warning en debug hasta que existan sus paquetes (docs/14 y fase B2B).

Desarrollo

npm install
npm run check       # typecheck + tests + build + presupuesto de tamaño
npm run playground  # http://localhost:8787 — demo con snippet y mock de /capture

El presupuesto es duro: el bundle core (dist/kilden.iife.js) debe pesar <15KB gzip; los chunks lazy no cuentan. npm run size lo verifica y CI local falla si se pasa.
