In plain words
To-Userscript is a Chrome extension that converts Chrome extensions into userscripts. It allows users to repurpose existing extension code as standalone scripts that can run in userscript managers. The tool is designed for developers who want to migrate or adapt their extensions to userscript format, offering a technical solution for code conversion and reuse across different scripting environments.

Convert any website into a React component2024 · chromewebstore.google.com · ▲326Hey HN, we built a Chrome Extension (https://www.magicpatterns.com/extension) that converts a snippet of any website to an isolated React component. Demo video: https://youtu.be/hutUYDkyE_A How it works: 1) Iterate through each node in the selected DOM tree, 2) For each element, find any matching CSS selectors / inline styles, 3) Use window.getComputedStyle to get the deterministic values, 4) Construct JSX It was pretty hard producing the minimal code necessary while maintaining the same visual look. To do this, we implemented things like abstracting out…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Hey HN! Pilots everywhere are required to keep a logbook of all their flying hours, aircraft, airports, and so on. Since I track everything digitally (some people still just use paper logbooks!), I put together some data visualizations and a few 3D globes to show my flying history. This globe is probably my favourite so far: https://jameshard.ing/pilot/globes/all If you’ve got ideas for other graphs or ways to show this kind of data, I’d love to hear them!

I was the main contributor to workout.lol, an open-source fitness app to easily build a workout routine. The project had traction (1.4k GitHub stars, 95 forks, ~20K visits/month), but was eventually sold due to video licensing hurdles. The new owner stopped maintaining it, and the repo went abandoned. Over the next 9 months, I sent 15 emails to try to save it : no replies. Feature requests & issues were ignored. The community was left with a "broken" tool let's say. I couldn't just let it die So I built the new version from scratch with the same open-source spirit, but a better…
