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 🙏

Playwright Timeline Reporter

A Playwright reporter that turns execution traces (tests, hooks, fixtures) into a horizontal timeline rendered with Apache ECharts. It is designed to be consumed via npx playwright merge-reports so multiple shards can be combined into a single visualization.

Quick start

  1. Install the package next to your Playwright config (currently locally via the repo):
npm install playwright-timeline-reporter
  1. Run your usual Playwright suite while emitting blob output (per shard):
npx playwright test --reporter=blob
  1. Merge the blobs and generate the HTML timeline (defaults to timeline-report/index.html):
npx playwright merge-reports --reporter=playwright-timeline-reporter blob-report

Open the generated HTML file to inspect worker utilization, long hooks, and fixtures. The legend highlights hooks/fixtures so slow setup/teardown is easy to spot.

Example project

The example/ folder contains a minimal Playwright suite exercising hooks and custom fixtures. After npm install && npm run build in the repo root:

cd example
npm install
npm run test
npm run report

Then open example/timeline-report/index.html in a browser.
