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 🔜

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

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 🔥

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...

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!

🤔 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!
