New post! ✨ Prompt caching ✨

My first big project post for @ngrok.com. 5 weeks, 12217 lines of code, 195 commits. I poured a lot into this one, and learned a lot in the process.

I really hope you enjoy it ❤️

Great post by @addyosmani.bsky.social, my co-chair on @oreilly.bsky.social's upcoming May 8 online event about the future of software development. I've been writing about what AI needs to learn from internet protocols, and Addy makes it real with concrete examples of how MCP is doing that.

Sam Rose walks us through some real-world usage of TypeScript’s utility types in their day jobs, open source codebase to help those new to the language get to grips with this key capability.

It took a while but here is the next attempt to introduce object property tree-shaking: Please install rollup@4.29.0-0 and tell me if performance is ok and if you find any bugs with the generated code. Otherwise, I will take it live in the next days.

"Free background-image remover in the browser!" ⚡️

Excited to announce bg.addy.ie, a free little app that removes backgrounds from images directly in your browser! Privacy-friendly. Uses Transformers.js, RMBG-1.4 & MODNet.

In 2025 all our UI tests will finally run in a real browser again for the first time since Karma was replaced by JSDOM.

I'm so here for this.

.@danabra.mov Hello! Just curious, how that Bluesky web app doesn't ship CSS outside of JS script?

Just released Lightning CSS v1.24.0! ⚡️

Support for compiling the light-dark() color function, enabling simple OS + programmatic dark mode toggles! 🌘

Also improves minification for custom properties, @​keyframes rules, system colors, and more! 💪

I really like the performance of bluesky web app. Great job so far!

The new linear() feature means you can have bounce and spring easing in CSS. But, how can you convert JS easing functions to CSS? Well, with this handy web app! https://linear-easing-generator.netlify.app/

I want to thank @ped.bsky.social for being awesome!
