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

@orkestrel/workflow

A typed workflow engine for the @orkestrel line — a serializable Workflow → Phase → Task tree that a UI or an LLM authors as pure JSON, and a PURE WorkflowRunner engine executes by COMPOSING the shipped substrate (a per-phase Runner, Abort, Timeout, Budget, and a cooperative cross-environment Scheduler) rather than re-implementing its own concurrency / retry / abort machinery. Each task's run is a plain behavior-name string resolved once into a handler; wiring a task to a tool or an agent is an opt-in adapter shipped by the separate @orkestrel/tool package, composed into the caller's own functions registry.

Install

npm install @orkestrel/workflow

Requirements

  • Core is cross-environment ESM; ./browser adds browser-native cooperative scheduler backends (requestAnimationFrame / requestIdleCallback / Prioritized Task Scheduling), ./server adds the Node-native setImmediate scheduler backend

Status

Pre-release (0.0.1): the definition contract, the live entity tree, the pure-engine runner (a run-string / handler model — the opt-in tool/agent adapters and the depth/cycle-bounded agent-native recursion now ship in the separate @orkestrel/tool package), the durable WorkflowStore (in-memory + driver-pluggable), and the cooperative Scheduler (the cross-environment default plus the browser and Node environment backends) are all implemented and tested, but the public API is still unstable and may change without notice. The live tree also supports runtime-only pause / resume / wait (at both the workflow and phase tiers) plus a gated add / remove / move / update structural-mutation API (pending-suffix positions, append-only on a running phase), a hard destroy teardown alongside the runner's existing graceful stop, and a WorkflowRunnerInterface.execute overload that drives an already-built, caller-owned live tree instead of only building one from a definition. See guides/src/workflow.md for the full documented surface.

Package

Published as three environment-scoped entry points per the exports field in package.json: . (the shared, environment-agnostic core — the definition/entity/runner surface plus the cross-environment Scheduler default), ./browser (adds the browser-native scheduler backends), and ./server (adds the Node-native scheduler backend). Core ships dual ESM+CJS builds; ./browser is ESM-only.
