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

dsh-ros2-state

Control-plane state client for the dsh-ros2-sidecar data plane (逻辑直连 · 物理分离): a long-lived Unix Domain Socket connection (newline-JSON), letting the Agent read reduced, fresh robot state in milliseconds — no ROS2 subprocess per read, because the sidecar continuously reduces high-frequency topics into a semantic cache.

  • src/state-client.tsStateClient (get / snapshot / subscribe / close), UdsStateClient impl (request_id concurrency, heartbeat, STALE/DOWN/TIMEOUT)
  • src/tools.tsstate_get / state_snapshot (read-only), via the deps.state seam
  • src/config.tsstate { socketPath, timeoutMs, tcp }

The sidecar (data plane) is dsh-ros2-sidecar; this package is the control plane that connects to it. See docs/sidecar-design.md.

Config (state.socketPath): path to the sidecar UDS socket. fail-closed: safety-relevant reads surface STALE/DOWN as structured errors — treat them as unsafe.
