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 🙏

Readme

@animastor/web-book-session

Book session identity contour for the Animastor web frontend — the single owner of the open-book identity and its persistence.

Owns

  • bookId / buildId signals — one source of truth, no fork
  • loadBook(id, build) — the only sanctioned identity mutator (persist on non-empty id, clear on empty — animastor:currentBook)
  • stashBookSessionForUser(uid) / restoreStashedBookSessionForUser(uid) — per-user stash pair (animastor:currentBook:user:<uid>) used by authStore on logout/login
  • setGenerationBuildId(build) — the controlled adapter through which the generation flow updates buildId (one signal, two legal writers: loadBook + this adapter)
  • readPersistedBookSession() — read-only view of the persisted session (used by fileStore's restoreBookSession; the write path stays here)

Does NOT own

  • phase / errorMessage — shared session status (dual-writer contract); host-owned in generateStore
  • restoreBookSession() — File-flow orchestration; stays in fileStore
  • auth login/logout lifecycle — stays in authStore (this package never imports authStore; the direction is authStore → this package)
  • generation orchestration, playback, navigation — host side

Dependency rules (guard-pinned)

  • Runtime dependency: @preact/signals ONLY.
  • No imports of host stores, api/client, app/*, pages/*, or any other @animastor/* package.
  • No module-global mutable state beyond the two exported signals.

Consumers reach the identity through the host's generateStore compatibility re-exports — the consumer import surface is unchanged.
