There is critical vulnerability in React Server Components disclosed as CVE-2025-55182 that impacts React 19 and frameworks that use it. A fix has been published in React versions 19.0.1, 19.1.2, and 19.2.1. We recommend upgrading immediately. react.dev/blog/2025/12...

JavaScript top-level await is no longer considered 'baseline' due to a pretty big Safari bug caniuse.com/mdn-javascri... The module graph fails in cases where two modules import a third at the same time. Demo: random-stuff.jakearchibald.com/bug-repros/t... It's best to avoid the feature for now 😔

Ages ago, when I was still a student, I taught myself Ruby on Rails for my senior thesis and fell in love. Fifteen years later, and I’ve used Rails at every job I’ve ever held in the tech industry. Fifteen years, and I still love Rails! But there’s something rotten at its core, and we share a name.

Just published an article series on how #WebAssembly Component Model can be used to build multi-language 🧩 plugin system that work seamlessly across 🛠️ CLI and 🌐 browser! Real-world examples with #Rust, #Go, #C & #TypeScript plugins. #WASM #WASI 🦀 dev.to/topheman/web...

The WebAssembly 3.0 spec is complete! webassembly.org/news/2025-09... This includes major features like GC, 64-bit memories, exceptions, and tail calls.

Built an automated distribution pipeline for my #Rust project! ⚡️ Cross-compiled for Linux/macOS (Intel/ARM) 🍺 #Homebrew formula auto-updates 💻 Shell completions bundled (bash, fish, zsh) 🤖 Custom GitHub Actions #CrossCompilation #GitHubActions #CLI github.com/topheman/web...

Is there a tool that, given a set of .d.ts files, gives you the minimum version of TypeScript supported? TIL @nuqs.47ng.com requires TS ^5, and that requirement came in silently as a feature was merged (const modifiers on generics). I need to automate this to prevent further type breaking changes.

🚀 My #WebAssembly Component Model based project can now handle WRITE operations in the #browser version! Forked #bytecodealliance/preview2-shim to fix filesystem issues. Now plugin-tee works perfectly in both CLI and web. #WASI #WASM #webdev #rust 🦀 github.com/topheman/web...

MIT’s NANDA initiative found that 95% of generative AI deployments fail after interviewing 150 execs, surveying 350 workers, and analyzing 300 projects. The real “productivity gains” seem to come from layoffs and squeezing more work from fewer people not AI.

tsup is not actively maintained anymore 👀 With >9M NPM monthly downloads and >10k GitHub stars, tsup is undeniably a popular choice for bundling. Unfortunately, it is not under active maintenance anymore. Thanks to @egoist.dev & contributors for all the work on tsup 🙏🏻

In the latest @rolldown.rs powered @vite.dev version, we've enabled the rust-based resolver plugin by default! This will lead to even faster builds in case you don't use the experimental native plugins yet. Wanna try out more native core plugins? Then enable them and make sure to use rolldown-vite

the main thing that makes me uneasy about llms is the cultural backdrop of global war on knowledge. the war on knowledge isn’t new but now it’s cheered on from tech too. tools for thought pivoted to slot machines because that’s what people want. “how things work” is buried under opaque indirections

obviously actual domain knowledge isn't going anywhere so it seems like the gap between more experienced and less experienced developers will widen? with less knowledge transfer and incentives to learn. i've learned a lot from conversations i'm no longer observing

👀 React + throw a promise technique, soon deprecated? If you throw promises to trigger Suspense boundaries, it looks like a good idea to migrate to React.use() PR not merged yet, but it's likely React will print a warning

#WebAssembly Component Model is promising, but examples are either too simple or too complex. I built a REPL with plugins that work in both CLI & web, sandboxed by default, and the REPL logic itself compiles to #WASM. Beyond hello world but still learnable! #WASI #rust 🦀 github.com/topheman/web...

Au CFP de BDXIO la section « talk reference » est primordiale, donnez lui un peu d’amour ! Le processus de notation est anonyme: on ne sait pas qui postule sur quel sujet. L’abstract ne peut pas rendre compte de toutes les notions abordées, et on a besoin de savoir de quoi vous allez parler.

Question: what are the common "meaningless" GitHub comments you tend to see? "+1", "any update?", etc. - things that don't add to the conversation at all. Context: writing a package to detect these automatically, so I can automate posting friendly replies on GitHub ~ github.com/JoshuaKGoldb...

⭐️ e18e is doing some awesome work fixing the world of outdated JS packages. Goal: upgrade deps that are boated, abandoned, stuck on common js, etc through open source contributions and build tools. Some Vite maintainers there too. Follow their work! e18e.dev

Everyone can make software now, no more need for developers to implement your ground-breaking idea. 😉 Until ... "fix it {AI}" doesn't cut it anymore while AWS and OpenAI bills are piling up or the project is down. 😇 #vibecoding #ai

Wait... what? I accidentally ran `npx` without a package and got this. How did I not know this was a thing?

You can pass sub-classed Promises to React such as in use() with the fields status and value or reason. This allows React synchronously read the value without waiting on a microtask. This is much faster but it also ensures compat when someone needs flushSync(). Microtasks are bad, mkay.

Node.js will no longer ship corepack starting from v25. This might make a lot of people sad, but it was a problem in terms of project maintainance. 🧵 github.com/nodejs/TSC/p...

node folks put a lot of energy to backport important features, so the ecosystem can move forward years in advance. It requires a ton of hard work that sometimes goes unnoticed. To everyone working on node, we appreciate your efforts 🙏
