And so it begins. I'm building an app to fight global food waste 🍏 github.com/barclayd/kee... SwiftUI devs, give me tips please #buildinpublic

KeepFresh v1.1 (my food waste tracking app) just dropped! Edit, move and add additional food items in a flash. Blazing fast search from 3mil+ grocery products that's growing everyday. Find all your supermarket favourites - guaranteed. Give it a try! apps.apple.com/app/keepfres...

Hello, friends! After 10(!) years of #AdventOfCode, I've made some changes to preserve my sanity: there will be 12 days of puzzles each December (still starting Dec 1) and there is no longer a global leaderboard. Read more: adventofcode.com/2025/about#f... adventofcode.com/2025/about#f...

Getting ready to launch my first app to the App Store since iOS 13. Is Combine dead? Doesn't look like Apple have given it any love since 2019 developer.apple.com/documentatio...

Is there a specific reason @vite.dev doesn’t offer a runtime for a Node.js server? Feels like there’s so much opportunity to improve server build tooling. Surely lots of this must exist already from @vitest.dev and vite handling SSR?

Want an easy way to stay up to date with new releases of libraries, frameworks and tools you use #buildinpublic? Easiest way I've found: Go to the relevant Github repo, click on Watch -> Custom -> Releases, and you'll get notified by email every time a new release is made 👌

Lynn’s portfolio refreshes are legendary. Love seeing the clever ways she manages to make things responsive. This year didn’t disappoint. ✨

Google Calendar see how meetings you already have booked for 2025

Say you're working on a UI design from Figma that's using hex codes for colours: If you stumble across a new colour to add to the UI e.g. #EAF2FC, does a tool exist to automatically determine the relative value of the new colour to your existing colour set? Ideally would return blue-100 here

"Hey Siri, define recovery winter arc" 📈 *Disclaimer, my work required me to use a different Github account so these are all purely open source commits. Feels great to be getting back to side projects and super motivated to make 2025 the year they go live. Happy New Year everyone 🎉

The Next team are ridiculously good at this. We need more people in the react-router/Remix ecosystem to follow suit

The struggle is real.

Jumping onboard the Ghostty hype but I'm loving it so far 👻 ⚡️It's super fast, works with existing zsh configurations, great built in themes too. It's my go to Terminal now. Seriously tempted to learn Zig following Ghostty's and Bun's track record for speed

Inching closer to getting KeepFresh live (the app I'm building for fighting food waste). Keeping to a strict MVP is a challenge but motivated to share a TestFlight link in early January. Back to designing the last screens and then hooking up the API 🚀 github.com/barclayd/kee...

“The best designed software is frictionless to change” 👆I’ve come up with my first engineering principle after nearly 6 years of professional software engineering at some of the biggest companies in the UK Blog post incoming 👀

I love Array.reduce, but I find myself writing less of them as the browser primitives get better. Map + Object groupBy is one place you can now get rid of reduce for www.youtube.com/watch?v=1bfK...

TIL I've been sleeping on folders in Mail for over a decade 🤯 Today is the first time I've seen my inbox at 0 since the day I setup my email account. Feels great to have things organised. Now to create an LLM that can do all future organising for me 🧠

Really liking the look of NanoIDs. URL state is important and should be a design consideration imo. Excited to give these a try in my new project

More API products should return errors with links to docs. I suspect I get fewer support tickets and quicker integrations because of that. For every possible API error, I return a link to the dedicated page on the possible reasons and how to fix it.

TIL that I never need to lose my inline styling changes made in Dev Tools ever again 🤯

Thank you. I really like react scan and think it's awesome. But I wish it also had tools for before/after measurements that showed whether optimizations paid for the added complexity in perf gains.

This is super neat from @wesbos.com as always 🔥 Great to see focus on accessibility too. CSS grid is super underrated and can help solve so many issues more elegantly than flexbox. Really hoping the CSS-first configuration in Tailwind v4 makes writing grid css easier than before

As I understand, SB leans heavily into module mocking, which yields an integration test. I believe a proper way to test RSC is an e2e test that runs the underlying framework, be it Remix or Next, in its entirety, executes routes, loaders, server-side code as it happens in production.

It’s that time of the year 🥲 @publicdomainrev.bsky.social #domain #developer #coding

Another reminder of the amazing impact @tannerlinsley.com and the maintainers of his projects have had in the front end ecosystem. Great to see more commonality within our community, we’re so much more powerful working together

The wide screen display of the Vision Pro is quite amazing!

As it often comes, one should test a thing similar to how it's used. RSC is by design a full-stack feature requiring the client and server/build. It's crucial we preserve that requirement in testing. The easiest way to do that is to build your app and interact with it. Almost a conventional e2e test

First PR merged into react router feels really good! github.com/remix-run/re... Excited to keep up the momentum and bring some really exciting ideas to the testing space

I've had a great discussion around testing RSC with @kentcdodds.com the other day. I will share my view on it once I've explored the tools (and wrote a few of those myself). So far, I see the in-browser, app-instance-per-test approach to justify its cost. It's always about justifying the cost.

I love that @bsky.app has a setting to make alt text required for images I post. Here’s a nice 🧵 on what should go in there!!!

There’s a $2.99 app in the App Store right now “My Classic - Retro Console” that’s hiding its true feature: an iPod Classic emulator that utilizes your Apple Music library. It works amazingly well and if you want it, get it before Apple pulls it (they will).
