Runtime Ownership Made Simple with TanStack Router Route-level ownership that your IDE can actually enforce

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 🌅

TanStack Router + Datadog RUM: How to? A practical guide to integrating Datadog RUM with TanStack Router for better monitoring.

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...

React router v5 🥶

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 🔜

I'm in a workspace based repo, but without a composite setup

If that helps

Yes, and even better than when tsc

Dm me if interested! And share to help us find the hidden gems of bluesky

Introducing, tanstack ai! tanstack.com/blog/tanstac...

It's been hard to keep it a secret, but I've loved seeing the tanstack team assemble around this new library to make it awesome! Check it out

Yup! We have both ts and tsgo installed, and webstorm will pick up tsgo :D

I've used this trick a couple of weeks ago! Thanks for sharing! :D

I should really get into the habit to blog more often.. 😅

It's mostly about ts expect error positioning, and if I recall, I've read an issue saying this is intentional

It's not perfect as in tsgo will complain about things tsc says it's OK, but it's not a lot of cases so when tsgo is usable within vs code, we will probably switch to tsgo fully

👀 I'm eager to know what they are

We have been using tsgo at work since 21th of August! Mainly for webstorm usage. It's been great! Night and day with the old ts server

How we accidentally made route matching more performant by aiming for correctness | TanStack Blog We achieved a 20,000× performance improvement in route matching in TanStack Router. Let's be honest, this is definitely cherry-picked, but the number is real and comes from a real production applicati...

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 🧵

I nearly finished moving our work codebase from router v5 to TanStack router, this would have been soo useful! 😔

I also use the gh pr checkout featue and every time I can push to the branch without any issues 🤔

I don't know if it's because of the gh cli or my git config

I have push.default = upstream so maybe git played a role there too!

Config ref

I was also going to suggest open code, it's solid and works amazingly well!

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? ⬇️

Already did 😎

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 ❤️

Storybook doesn't work when using rolldown-vite with `output.generatedCode.symbols: true` · Issue #6700 · rolldown/rolldown Hello, unfortunately, it's not working. I've created a minimal (as I can only have this bug while running storybook build) reproduction: https://github.com/beaussan/repro-storybook-rolldown-story-o...

Only one last issue and I can make the switch 🤩 last time we tried, the only thing that broke was our storybook documentation! Gigen it was on our design system, and in the same monorepo we can't have both vite and rolldown, we had rollback
