a mistake I see constantly: leaders go quiet when something went wrong in the absence of the real story, people will try to piece the story together from incomplete information a story always gets told. rumors are usually worse than the truth. be vulnerable: own it so you have a chance to recover

plenty of fixes deployed to rscexplorer.dev, but mostly i just feel a lot better about the code itself

I don't think we'll struggle with having too many ideas that we can't implement anymore Instead, we'll struggle with building too many things and can’t focus on one thing

Why can't I change port in Tanstack Start with Vite just by "vite dev --port 6000" and no port 6000 is not taken 😭

Researchers have found two new vulnerabilities in React Server Components while attempting to exploit the patches last week. These are new issues, separate from the critical CVE last week. The patch for React2Shell remains effective for the Remote Code Execution exploit.

@clerk.com Billing is all I need for my SaaS They offer pricing tables, waitlists, user management all in one. Why do I need 10 different providers? And before you comment, you don’t own your users. Stop as they offer a download option to get all your data Really impressed 👏

So excited about the video I’m dropping next week! Finally settled in my new apartment and man, it feels so good to get back in the routine!

maybe not the best moment for it but i finally condensed my “why react server components” into a short blurb that does well on HN

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...

pre Turbopack, we had "webpack_internals" in browser dev tools, does anyone know how I can see what files gets shipped to the browser now? it was easier to see "mark something use client and it gets included in the bundle" but don't see that anymore

Next.js has 2 Directives Everyone Mixes up 'use server': Marks a function to run on the server as a Server Action, but doesn't prevent importing in client components, leading to runtime failures 👉 'server-only': Prevents importing server code on the client, throwing an error to catch issues early

Great deals from @piccalil.li at the moment. Just bought Mindful Design, can't wait to watch it. piccalil.li/black-friday/

🍿 You might be leaking secrets in Next.js. Environment vars starting with NEXT_PUBLIC_ go straight to the browser yes, even API keys 😅 The fix? Use Server → Client Parent–Child pattern, do sensitive work on the server and pass only data down Read the full issue → dub.sh/avoid-leaking-secrets

spent the last day fighting a gnarly issue (bug?) in how Next 16 Cache Components interact with atproto OAuth flow (cc @matthieu.bsky.team). might be a Next bug or not, anyway i filed github.com/vercel/next....

Stop Infinite Re-renders Ever add a handler inside an effect, put it in the dependency array, suddenly…re-renders forever? That’s because your handler changes identity every render, the effect keeps tearing down & setting up again React 19.2 dropped useEffectEvent that fixes this 👇 dub.sh/3JmFcYR
