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 🙏

Portable DEKS document types, validation, and pure editing commands.

Readme

@deks-js/document

Contrato portable y offline de DEKS.

  • DeksDocument: único JSON canónico normalizado.
  • assertDeksDocument, parseDeksJson y deksDocumentSchema: validación defensiva y schema exhaustivo, también disponible como @deks-js/document/schema.
  • DeksPresentation: fachada scripteable que produce el mismo documento.
  • DeksCommand, batches/transacciones y DeksChangeSet: edición pura por revisión.
  • createDeksFile/readDeksFile: contenedor .deks determinista, content-addressed y sin dependencia de filesystem.
  • inspectDeksImage/normalizeDeksSvg y DEKS_IMAGE_LIMITS: una frontera portable para PNG, JPEG, GIF, WebP y el perfil SVG seguro y canónico de DEKS.
  • sniffDeksImageMediaType/inspectAndNormalizeDeksImage: detección por bytes, normalización y errores estables que Web, Desktop y sus adaptadores pueden traducir a su propia interfaz.
  • normalizeDeksFileAssets: verifica que los bytes entregados por un host correspondan exactamente a los assets embedded declarados por el documento sin persistir metadata del host.

El inspector recorre el contenedor raster completo: exige IEND/EOI/trailer y longitudes RIFF coherentes, cuenta APNG fcTL, GIF image descriptors y WebP ANMF, y limita cada imagen a 200 frames y 100 MP agregados además de 40 MP por frame. Es una validación portable de estructura; el host Cloud decodifica además los píxeles con Pillow antes de persistirlos.

JSON es la fuente de verdad. Tablas relacionales, archivos, estado React y snapshots del renderer son proyecciones. Los hosts resuelven assets y persistencia sin agregar campos al documento.

El SVG aceptado se parsea como XML con namespaces, nunca mediante regex o DOM. Core elimina la superficie activa (scripts, estilos, eventos, referencias externas, texto renderizado, fuentes, SMIL e imágenes anidadas), limita complejidad y produce UTF-8 determinista antes de calcular el hash del asset. Al leer un .deks, los SVG deben contener exactamente esos bytes canónicos.
