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

node-opcua-client-browser

OPC UA client SDK for modern browsers, using the WebSocket transport mapping defined in OPC UA Part 6, §7.5.

Status — scaffold only. This initial drop establishes the package layout, build toolchain, and Playwright E2E harness. The WebSocket transport, the createBrowserClient helper, and the prebuilt browser bundle arrive in follow-up PRs. Consult openspec/changes/add-browser-client-wsopcua/ for the canonical scope and roadmap.

Planned scope (upcoming PRs)

  • Endpoint URL schemes: opc.ws://, opc.wss://, ws://, wss://
  • Security policies: None, Basic256Sha256 (SignAndEncrypt)
  • User identity tokens: Anonymous, UserName/Password (password encrypted under Basic256Sha256 when applicable)
  • Services: Read / Write / CreateSubscription / CreateMonitoredItems / Publish

What is in this scaffold PR

  • Package skeleton (package.json, tsconfig*.json).
  • An empty source/index.ts that just exports a VERSION string; subsequent PRs add the actual transport implementation.
  • A Playwright test harness that builds a minimal test page with esbuild, serves it over a local HTTP server, and loads it headless in Chromium.
  • One smoke spec (test/e2e/smoke.spec.ts) that asserts the test page loads and the node-opcua-client-browser module evaluates. Later PRs replace this with full OPC UA Read / Write / Subscribe flows over opc.ws and opc.wss against a demo server.

Running the smoke test

pnpm exec playwright install chromium   # first time only
pnpm test:e2e                           # runs the smoke spec headless
