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 🙏

chat-glass

Visual thinking companion for Claude Code.

chat-glass gives Claude Code the ability to create rich, interactive visualizations -- diagrams, charts, comparisons, flowcharts -- and display them in a live-reloading browser viewer.

What it does

When Claude Code needs to explain something visually, it delegates to the chat-glass agent. The agent writes a self-contained HTML file, and chat-glass serves it in a browser viewer with a gallery of past visualizations. Everything updates in real time via WebSocket.

Quick start

npm install -g chat-glass
chat-glass install-agent

That's it. The agent is now available in Claude Code. When a visual explanation would help, Claude will automatically use it.

To install the agent for only the current project:

chat-glass install-agent --local

How it works

  1. Claude Code decides a visual would help and delegates to the chat-glass subagent
  2. The subagent writes a self-contained HTML file to .chat-glass/pages/
  3. The subagent runs chat-glass show, which starts a local server (or reloads an existing one)
  4. The browser viewer updates in real time via WebSocket
  5. A gallery strip lets you browse all past visualizations

Commands

| Command | Description | |---------|-------------| | chat-glass show | Open the visualization viewer (starts server if needed) | | chat-glass list | List saved visualizations | | chat-glass clean | Delete all saved pages | | chat-glass install-agent | Install the chat-glass agent file globally | | chat-glass install-agent --local | Install the agent for the current project only | | chat-glass --help | Show help |

Configuration

chat-glass stores data in a .chat-glass/ directory in your project root:

.chat-glass/
  config.json    # Server state (port, pid, timestamps)
  pages/         # Generated HTML visualizations
    latest.html  # Symlink to most recent page

The server listens on 127.0.0.1 on a port in the range 3737-3747 and shuts down automatically after 30 minutes of inactivity.

For contributors

git clone https://github.com/tfLConsulting/chat-glass.git
