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

@arch-engine/adapter-pnpm

Deterministic workspace-topology extraction adapter for pnpm-managed monorepos.

Purpose

This package teaches Arch-Engine to read pnpm-workspace.yaml workspaces with full glob expansion, exclusion-glob support, and the workspace:* / workspace:^ / workspace:~ / workspace:<version> protocols on dependencies, devDependencies, peerDependencies, and optionalDependencies.

It conforms to the internal ArchitectureAdapter contract introduced in Pass 1 (docs/adapters/multi-adapter-surface-spec.md §6). The CLI's adapter registry consumes it structurally — this package has no runtime dependency on @arch-engine/cli.

Installation

npm install --save-dev @arch-engine/adapter-pnpm

The CLI dynamically resolves this package at runtime when pnpm-workspace.yaml is present at the repository root. When it is not installed, the CLI falls back to @arch-engine/adapter-monorepo's line-based pnpm parser (degraded mode).

Determinism Invariants

The adapter is pure-fs read:

  • Never executes pnpm or any other package-manager binary.
  • Never reads node_modules/ or .pnpm-store/.
  • Never opens network sockets.
  • Never mutates the user's repository.
  • Re-running on the same source produces byte-identical output.
