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 🙏

Framework-agnostic DOM, SVG, and Web Animations renderer for DEKS presentations.

Readme

@deks-js/renderer-core

Renderer DOM imperativo y sin React.

const renderer = new RendererCore({ assetResolver, onOpenExternal });
renderer.mount(host);
renderer.renderSlide(document, slideId);
renderer.setViewportMode("presentation");

La misma instancia sirve al editor y al playback. El host puede aplicar y revertir frames transitorios sin mutar el documento ni repintar la escena:

renderer.previewElements(nextSnapshots);
renderer.restoreElements(elementIds);
renderer.setSelection(elementIds);
renderer.setOnionSkin(previousSlide, { opacity: 0.24 });

compileTransition() conserva el contrato 4.0. seek(milliseconds), setPlaybackRate(rate), getPlaybackProgress() y subscribePlaybackProgress(listener) exponen el único reloj lógico, pero Web Animations API sigue siendo propiedad imperativa del renderer. Los callbacks del host no avanzan frames.

validateSnapshot() valida el boundary portable y iconSvgMarkup() serializa los íconos offline registrados para adaptadores compartidos, incluida la exportación PPTX. Ninguno consulta la red.

Los enlaces HTTPS sólo se delegan a onOpenExternal en modo presentación. El renderer no abre ventanas y no descarga assets. Las transiciones usan Web Animations API cuando existe y respetan prefers-reduced-motion. La identidad estable de un elemento compila morphs geométricos; entradas, salidas y cambios discretos usan presencia o crossfade según los presets, movimientos por elemento y overrides del SlideTransition portable. React sólo inicia o interrumpe el playback: el renderer imperativo es dueño de los frames.

Los rectángulos proyectan los cuatro valores canónicos de cornerRadii en orden top-left, top-right, bottom-right y bottom-left.

Los cambios de fondo hacen crossfade entre capas para todas las combinaciones portables de sólido y gradiente lineal. Usan la duración efectiva, delay y easing del beat de transición; con movimiento reducido se aplica inmediatamente el fondo de destino. Un renderSlide() durante playback cancela las capas transitorias y deja ese snapshot canónico como autoridad.
