All-terrain dev working across web, native, TV, and backend for over a decade, with a particular masochism for React Native and NativeScript.

Pretty surreal to see @theo covering my article! I caught it live, so can assure it was a fun watch from my point of view. 🍿 Theo also caught the fact that React Native deploys to e-ink Kindles and PlayStations, which I overlooked! Tempted to add those to the addendum now 😄
If you want to embarrass a senior iOS engineer, ask them to explain the difference between Dynamic Frameworks and Static Libraries. Learn to reduce app bundle size, simplify your dependency graph, optimise launch performance, and accelerate build times. Read more here:…
As a former Smart TV dev, I can only think it’s a blessing that these devices can all fit on one desk
Android setup for @Backpack Each of these phones have had a specific issue that I couldn't reproduce on any other device. It could be general lag, a broken keyboard, inconsistent haptics or font rendering. You name it. The 3 phones connected are my daily drivers. I replaced…
If you're going to make a barrel module, at least do it with style
Best part of tech meetups is shutting up about the tech and going to a karaoke bar
At #ReactNativeJP, Shunsuke-san revealed that the following Amazon devices, plus the new Fire TV 4K Select, all run React Native.

React Native’s networking stack is built on native APIs: - iOS and macOS: NSURLRequest - Android: OkHttpClient - Windows: winrt::Windows::Web::Http There’s a “last mile” of non-native code to expose it as familiar JavaScript APIs, sure, but the hot path is all native.
Learning the right way to consistently vertically align text across both iOS and Android thanks to @mrtry_'s talk at React Native Japan! The key to victory is the `includeFontPadding` style! Also iOS doesn't have `textAlignVertical`? 😮
don't worry, sheeple devs always just parrot popular claims without substantiating them
I hear this a lot, but in my experience React Native is very fast and can be even faster than native apps. Is there any evidence it’s slow, or is this just a common misconception?
OSS contributions are measured in bread machines
Node & TypeScript excitement 😉 Marco tells the story of implementing Type Stripping support in Node. It involves a lot of collaboration across the JS ecosystem. 🔷 First cut took 20 days (fast for Node) 🔷 TS delivered flags to ease adoption 🔷 Marco's reward: a bread machine
If you ever feel like being truly hazed, try asking an LLM to implement streaming file uploads for the Electron main process. It's a pinball machine that ricochets between being wrong for every possible implementation of networking that Electron has access to.
Nice! I’d say when comparing Expo / React Native to single-platform dev, some easy things become hard, yet some hard things become easy. Personally, I greatly prefer the tradeoff that Expo / RN strikes. I like writing TS, developing in VSC and expressing UIs in React + Tailwind.
👀 First time built something using Expo. Was quite a hassle compared to SwiftUI lol

Building React Native Fiddle (today: debugging Metro)
Businesses need to get into the habit of valuing engineering hours properly. Sure, CI/CD and SaaS offerings do cost a certain amount, but spending weeks of engineering time naïvely trying to implement a fraction of what something like EAS gives you is just short-sighted.
Team debated: GitHub Actions vs Jenkins for CI/CD. Jenkins advocates: - We already have it - More powerful - Self-hosted - Free (ignoring ops time) GitHub Actions advocates: - YAML in repo - No server to maintain - Modern UI - Faster Decision process: - Ran both for 1 month -…
