Nico and I have made it easier to extract tools, agents, and components for structuring your AI SDK apps:

Do you remember Atom? For many it was the first IDE and we have fond memories of it! But what happened to Atom? Where did it go? Why did it die? We explored the full story of Atom in our newest full length YouTube video 📹 (it's below!)
I think authentication in E2E tests can be better. That's why I'm building a library called Playwright Persona. Learn what it is, why it exists, and how to use it: github.com/kettanaito/pla… And, please, share your thoughts! 🙏 Thank you.

Weekend project: adding validation ✅ - Deserialise → parse → validate on read - No validation on write yet (would be a breaking change, could be an experimental opt-in flag) - Standard Schema based, or pass in any sync function that throws on invalid values (for other libs)
@SandroMaglione Using effect/schema, but hitting an issue: optional fields come from FormData, which always returns "" — even when the user leaves the field blank. This breaks .optional(S.string.minLength(1)), since "" ≠ undefined. Best way to model "optional but non-empty if present"?
What are people using instead of Storybook these days? One simple alternative I enjoy: Create a page in the app that shows reusable components. This page isn't linked to by the nav, so it's only visible for developers. This avoids the overhead of keeping up with Storybook's…
I spoke at @ReactSummit this week on "The State of React and the Community in 2025", addressing many common questions and concerns I've seen. Slides are on my blog: blog.isquaredsoftware.com/2025/06/presen…
And, as always, you can support the effort behind MSW by becoming its sponsors on GitHub: github.com/sponsors/mswjs Thank you.
Is creating schemas at runtime from JSONSchemas fetched over the network a bad practice @colinhacks @EffectTS_ ?

i'm watching rag systems evolve from "chat with your pdfs" into something far more valuable. the problem? most rag implementations are primitive text chunking exercises that miss the real economic opportunity. here's what actually matters: extract structured data, not just…
Damn, I really want to make a "UX Patterns For AI Applications" course All the hard stuff like stream resuming, generative UI, properly streaming markdown, editable plans, showing LLM progress
After so many years #React docs finally teach UI with state machines. They still make a mess with Boolean states, but hey it's a start! @DavidKPiano your preaching finally worked 🤣 react.dev/learn/reacting…
I came across SO many misconceptions around testing over the years it's eye-opening. No wonder so many devs find themselves lost and then missing the point of testing altogether. You DON'T need 100% code coverage. You DON'T have to do TDD. You DON'T have fill in the pyramid.
The @vercel Chat SDK now features stream resumption. This makes AI conversations resilient to network hiccups and reloading or sharing a chat mid-generation. This is especially valuable for long responses (e.g.: Deep Research). No proprietary APIs, no sticky load balancing, just…
Yup. Lawyers, nurses/doctors (only for triage), notaries, customer service agents, etc. Everything that is "fact checking and document drafting" can be automated easily. Bake that with Blockchain verification and the world could save real money.

My mom just told me she didn't want to pay $350/hr for her attorney to draft a contract, so she used ChatGPT. She then showed it to him... "This looks perfect! Nothing I would change. Who wrote it?" Btw my mom still asks for help to fix her printer. Are lawyers cooked?
