Did you know Storybook has @tanstack.com React support built-in? 🛣 Automatic Router wrapping with memory history 🧭 Type-safe route, params, query, and path configuration 🌲 Code-based, file-based, and nested Route support 🧪 Auto-mocked Start server functions ⚙️ Zero-config setup

💬 "We went from one repo to 25 of them, just to build one frontend app." New episode with TanStack Router maintainer @beaussan.io: killing micro frontends, 25 repos to 1 monorepo, and migrating 1.5M lines off React Router v5. 🎥 https://youtu.be/3jAApeeDvNU @beaussan.io

So happy to meet @beaussan.io IRL ! We had lunch at a restaurant called "Hopen source" !

I wrote about how I use AI with Obsidian without letting it take over my notes. The core idea: every AI run should leave a visible diff, an audit trail, and a clear point where I decide whether I trust the result. beaussan.io/blog/ai-obsi...

I know I'm pretty late to the obsidian <> ai stuff, but after more than 3k notes, I didn't wanted an ai going loose in my vault. But I now have a pretty nice setup that manually sync, snapshot before and after the ai work, and it's been quite helpful! All built by opencode sdk

Thanks a lot React Paris for having me! It was a great conference, with amazing folks joining! Also, thank you everyone that gave me amazing feedback on my talk! I'm glad it resonated with soo many of you! Here are the slides if you missed it! beaussan.io/talks/2026/r...

@tanstack.com crew assembled at #ReactParis With @tannerlinsley.com @beaussan.io and Harry

@beaussan.io on stage 🤩

ICYMI, ReactParis is happening tomorrow. Dinner with @tannerlinsley.com @brillout.com @beaussan.io

I’m on my way to #ReactParis, see you all soon! 🎉

🚀 @beaussan.io is speaking at react.paris 2026 Nicolas's company ditched micro-frontend 🫨: - CI down from 45 to 5 mins - Deployments from days to 20 mins - Velocity up 75% Discover their #monorepo migration with #Nx, merge queues, and trust-rebuilding strategies after a failed first attempt.

Cut our ownership providers from 245 → 3 using @tanstack.com Router's staticData API 🧹 Route-level ownership that TypeScript enforces at compile time. Shared layouts just work. Your IDE tells you when you forgot to assign a team. Type-first routing is a game changer 🌅 beaussan.io/blog/runtime...

Wrote up how to integrate TanStack Router with Datadog RUM after reverse-engineering their codebase tldr: subscribe to onResolved, track views manually, get proper route grouping No wrappers needed, just a clean subscription pattern : beaussan.io/blog/datadog...

After a couple of months, I'm happy to share that @payfiteng.bsky.social main app is now running on @tanstack.com router (250+ routes)!🎉 This allowed us to have a snappier app, typesafe routing and found a couple of bugs thanks to better types! I am planning an article about the approach 🔜

Path matching in a router? How hard can it be 🤷‍♂️. Hard to do correctly. Very hard to do fast on top of that. This is a great blog post about the recent core refactoring done in @tanstack.com router 🔥

Prisma 7 is here! 🦀 Rust-free Prisma Client as the default 💪 90% smaller bundle size & 3x faster queries 🔌 Direct connections to Prisma Postgres We've been building towards this for months, so let's see what's in this release 🧵

oops I missed the outage, I was too busy writing in Obsidian

🤔 What if there were a conference without talks? Just hanging out with OSS maintainers & builders, seeing what they’re working on, and learning cool stuff by actually talking to people. 🤯 What if hallway track turned into the whole event! 💡 @tannerlinsley.com is exploring it. Interested? ⬇️

There is some opportunities that feels unreal. This is one of them! I've joined the TanStack Router team to keep pushing the boundaries of typescript and routing! Huge thanks to @manuelschiller.bsky.social and @tannerlinsley.com for their trust ❤️

I am looking for a full-time job. Being independent in open source for 3.5+ years has been wonderful. I've gotten done most of the high-level goals I wanted to, and miss having people & structure around me. If you know of a role for a staff-level TypeScript+web developer, let me know! 🙂

I'm really struggling with @pnpm.io , especially around libs that are duplicated since peer are resolved to different version, and singleton instance (like vitest snapshots) breaks... 😢 Is there a secret or override all the things ? pnpm.io/how-peers-ar...

📚 Continued writing about @tanstack.com Router this weekend, trying to explain one of the imo best features the router has to offer: Context Inheritance that works in a fully inferred type-safe way across nested routes 🔥

Let's make the web fun again!

Multithreaded linting just landed in ESLint! eslint.org/blog/2025/08...

Isaac is an awesome person, very knowledgeable and now, on the market! If you run large monorepos, or codebases in general, I'm sure he will be able to help you out!

And that 2h was from last October! Now we are at 20 minutes from branch pushed to deployed! Including merge, dev, staging, e2e and prod deployment 😍 Read more about the story on the Nx blog

📚 Finally found the time to write about what I think the best parts about @tanstack.com Router are. Yes, type-safety (duh), but there is so much more to talk about. Honestly, coupled with React Query, this is the most productive stack I’ve ever worked with 🚀

🎉 Excited to share that I've been promoted to Senior Staff Engineer @payfiteng.bsky.social ! Proud to have helped transform our frontend platform into one of our best developer experiences. Here's to the next chapter! 💪

I'm hearing more and more news like that, I'm not sure about attending us based conference or applying to CFPs 😢

This is dedication! @beaussan.io travelled all the way from React Paris to Nx Summit EU to bring me @tanstack.com stickers!! This guy rocks! 💪

On the road again! This time, heading to Amsterdam for @nx.dev Eu Summit! See you there! 👋

This is huge!!! (and no, it's not an April fool 😁 ) Kudos to the Nx Team, they have backtracked the original decision, and gave a full refund to the ones that paid for it

Thanks a lot to @sapphi.red , we now have a web worker building! github.com/vitejs/rolld... And we may have found the reason why it's slower, latest run is 22 seconds faster for PayFit app build on rolldown! 🎉 Always bet on Vite.
