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

@gwn-sheet-stack/core

Framework-agnostic primitives for sheet-stack: the stack store, FSM, snapshot/mount-window, presentation rules, event bus, and router-adapter contract. Animation and gesture handling are intentionally the adapter's responsibility.

You probably want to install one of the framework bindings instead — @gwn-sheet-stack/react or @gwn-sheet-stack/svelte. This package is what they share.

Install

bun add @gwn-sheet-stack/core

@gwn-sheet-stack/core must be present as a single instance at runtime. It is declared as a peerDependency of every framework and adapter package; install it once.

What lives here

  • StackStore — createStackStore, LRUMountWindow, Layer, State, RouterAdapter. The vanilla-TS state container that runs the FSM, broadcasts changes, owns the mount window, and wires the router adapter.
  • FSM — LayerPhase (mounting | presenting | active | background | dragging | snapping | dismissing | evicted), LayerEvent, renderModeFor, PresentationKind.
  • Presentation — inertForLayer.
  • Router — historyAdapter reference implementation; concrete adapters live in gwn-sheet-stack-adapters-router-*.
  • Event bus — EventBus.

Domain vocabulary

The full vocabulary (Layer, Stage, Stack, Detent, Snapshot, Mount window, …) is documented in CONTEXT.md. Use those terms exactly.
