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 🙏

@klyfa/core

Platform-agnostic analytics core shared by @klyfa/web and @klyfa/react-native.

You probably don't want to install this directly. Reach for @klyfa/web (browsers) or @klyfa/react-native (React Native) — each depends on this package and adds its own platform layer (storage, transport lifecycle, page/app navigation). This package is the shared engine underneath.

What's in here

Pure TypeScript, no react-native / DOM / Node dependencies:

  • KlyfaAnalytics — the queue + consent + delivery engine: batching, GDPR consent gating, and classified retry (transient failures re-queue for free and honor Retry-After; only server errors count against a bounded poison-event budget; the queue is drained with bounded concurrency).
  • Api — the /track HTTP client with the failure classification the engine relies on.
  • ScreenTimer — time-on-screen arithmetic: accumulates only while the screen is in front of the user, so the platform layer just has to drive it from its own lifecycle (tab visibility on web, app state on native).
  • ExposureTracker — feature-flag exposure dedup.
  • compareSemver / isComparableVersion — version helpers (kill-switch).
  • Shared types (AnalyticsOptions, ConsentState, TrackProperties, …).

A platform package subclasses KlyfaAnalytics and provides an environment layer via onQueueChanged() (persistence) and lifecycle hooks.

Lineage

Forked from OpenPanel's MIT-licensed SDK core and rebranded to the Klyfa wire protocol (klyfa-* headers; the server also reads openpanel-* for already-shipped app versions). See the platform packages' THIRD-PARTY-LICENSES.
