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.

@opensankey/tableau

Tableau dashboard extension for OpenSankey. Renders interactive Sankey charts inside Tableau dashboards.

Setup

Build the extension:

pnpm build

Host the built dist/index.global.js and an index.html on a web server (HTTPS in production, localhost for development).
Create an index.html that loads the Tableau Extensions API and the built bundle:

<!DOCTYPE html>
<html>
<head>
  <script src="https://cdn.jsdelivr.net/npm/@anthropic-ai/tableau-ext-api/lib/tableau.extensions.1.latest.js"></script>
  <script src="./dist/index.global.js"></script>
</head>
<body></body>
</html>

Update the source-location URL in opensankey.trex to point to your hosted index.html.
In Tableau Desktop, drag the extension onto your dashboard. The extension reads from the first worksheet and auto-detects dimensions (source, target) and measures (value).

Data Requirements

The worksheet should contain at least:

2 dimension columns (text) — source and target nodes
1 measure column (numeric) — flow value

The extension auto-detects column types and maps the first two text columns as source/target and the first numeric column as value.

Events

The extension automatically re-renders when:

Filters change
Mark selection changes
The browser window resizes
