It’s December 12th and I already maxed out my included-request usage for the month in Cursor. 🙃

🆕 Knip for Editors Trust me, I've poured in A Ton of Love ✂️ This isn't just a plugin to show unused exports. It offers a unique way to view & navigate your code and connect the dots. Feels like there's so much potential here. Excited for you to try out the preview! 🙏 → github.com/webpro-nl/kn...

Gemini 3.0. 👀 blog.google/products/gem...

📚 I haven’t written much at all about the “front of the front-end” on my blog, but since I’m now working on the design engineering team @sentry.io and also maintained the design-system at adverity for some time, I have opinions there as well 😬:

Some quick observations after trying out Claude Code (CLI) for a couple tasks. 👀 Overall verdict: results were fine — good enough for day-to-day feature work. But nothing noticeably better than what the underlying model already gives you.

Cursor 2.0 is out. 👀 The most interesting bits to me: - Multi-agent support - Proprietary model (Composer) - Built-in browser - Voice mode cursor.com/changelog/2-0

I fixed some typos in the code. I commited it with the following message: "Fix types". 🙃

📚 As promised, a quick writeup on how syncing state - even if it’s between server and client state - can be avoided if we’d just derive state instead:

I want as many developers as possible to experience the joy of refactoring their code when they have a good test suite by their side. It's infectious. You'd want that feeling all the time.

💡 TIL: Zustand has an in-built middleware to persist the store (by default in local storage). See me remove all useLocalStorage hooks tomorrow. 👀

Today, I one-shot prompted a small web application, front-end and back-end included. The interface has to be reworked entirely and the backend reviewed, but it's functional. You can call me a full-stack engineer, I suppose. 🤷

I’ve been experimenting with Cursor Background Agents for a new project. Biggest takeaways: start with clear repo rules, write prompts that force planning & checks, run agents one-at-a-time early. Background agents give me ~50% of a feature. More in the article. blog.tomaszgil.me/enhancing-so...

New article in the works. ✍️

📚 Whenever I see useCallback, I wonder: why do we need it here? And a lot of the times, when I look deeper, I see that it actually doesn’t do anything. I think a lot of code-bases would be better of just not memoizing at all - and then let the compiler do it for you:

Setting up a brand new app is both so exciting and taxing. 🥵 My brain no longer shuts off after work recently. I'm still building, just in my head.

You know what AI can't do? Auth.

It's done.

How it feels to ask for approvals on your PR

Hey Friends 👋 Looking for advice, small project, React SPA, we want to focus on integration test with some unit tests: Jest or Vitest? Hit me up with your best takes. 🙇

Today, I've joined OpenSpace as a Senior Front-End Software Engineer to build a platform with a complete visual record of construction projects, powered by AI. Excited about what's ahead! 🎉

Yes, I worked on an AI sidebar, thanks for asking.

I've managed to fix the flash of the wrong theme on my website. I have tried at least half a dozen approaches over the last few months. Go see it here: tomaszgil.me ✅ Respects color scheme preference. ✅ Stores the value in local storage. ✅ Works with SSG. Here's how it's done. 🧵

Introducing large-scale tooling changes in software projects can be overwhelming. I just wrote a guide with a step-by-step process for evaluating, integrating, and getting teams on board with new tools, inspired by my work at Salesloft. 👇 blog.tomaszgil.me/introducing-...

I've been using Wispr Flow for a week or so now (mostly for prompting, but also for writing this very post), and I absolutely love it. Would recommend it as an addition to any software engineer's workflow. 🚀 wisprflow.ai

Fantastic advice not only on mentoring, but also on how to operate effectively in a rapidly-changing environment. 🙌 From @swizec.com swizec.com/blog/my-ment...

⚡️ Vite 7.0 is out! - Browser Target Changed to Baseline Widely Available - Node 18 support dropped. Vite is now distributed as ESM only - And feats, fixes, and cleanups, while we prepare for rolldown!

I have been using brag docs for a couple of years already, but it didn't occur to me to try to automate it. Another great newsletter issue from @brittanyellich.com 🙌 archives.balancedengineer.com/archive/brag...

I'm craving some new swag. 👀

I’m a newbie to automating things What do you automate? What tools do you use?

It's official: apparently I'm writing my first AI chat experience. 👀

Recently, I have found the first case where AI wasn't good enough to give me any working code — a custom random card drawing animation. I've tried multiple prompts in Cursor and then in Claude, which tend to be good with UI, but none of them really gave me the result I was looking for.

🌍 #i18n may be for you – even if your app supports just one language. It’s not just about translation – it’s about clean, resilient UI. 7 golden #frontend i18n rules, ICU → Intl → Temporal → layout tips, and more! chudy.me/blog/buildin...

React already has a way to express rendering or not rendering elements; it's called JSX.
