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 🙏

@effect-state-machine/studio

Studio — the standalone devtool for effect-state-machine. A local server plus a browser interface that any number of applications — browser or Node — connect to over WebSocket.

Run

npx @effect-state-machine/studio        # serves http://127.0.0.1:4747

Then attach a running machine from your application with @effect-state-machine/studio-client.

What you get

The interface shows the behavior map with depth-limited focus and traversed-edge emphasis, the current actor state as JSON with an actor-local line diff, node and event detail cards with their JSON Schemas and source links (opened in your editor by the local server, --editor to configure), grouped quick events, a custom-event editor, and a semantic history with local time travel — the cursor is per-viewer state and never touches the wire or the machine.

Multiple root machines appear as sessions in the top bar; descendants stay in their root session, and disconnected sessions keep their history inspectable.

To embed the same interface inside a React app without the CLI, use @effect-state-machine/studio-react.
