Tanstack Start + Convex version of voting for the Roundest pokemon

Convex backend I was initially developing on my own, but hit into a lot of issues with the random element and convexs caching. Initally was trying to do the random selction client side, but I've sense just copied Jamies backend code for now. I have some ideas to change it for the "turbo" version I want to make.

For the main vote page, I've actually not used a lot of the router integration with Tanstack Query. I found it easier to decouple the state of the random seed from the router, so the battles are loaded as not critical data inside it's own Suspense boundary. Still very fast.

I had some issues with client server hydration mismatches with the random numbers as well, so I created a server function to just return Math.random and have a queryOptions object with staleTime: Infinity. So when the query client rehydrates on the client-side it doesn't fetch again. As an aside, the Tanstack Query integration seems to be invalidating everything including my own queries when you call a mutation, so no need to invalidate manually.

Next TODO for this app

• [ ] loc
• [ ] turbo route
• [ ] use framer to provide clean transtions between different pokemon battles (over the coarse of voting and fetching next pokemon)

loc TBD

This is great!

Yeah thanks for your work on the query integration. I'll be using it as a playground for silly optimization for a bit I think

[versed elbow]

Yeah the query invalidation stuff is slick, you still need to invalidate other non-Convex fetches but Convex queries all update together so never need to be invalidated

@terse ledge was thinking about doing some perf stuff too, imagine prefetching the next pair

@hushed eagle +1 this is great. Any chance you have a video demo loading too? lol

[hushed eagle]

Maybe once I've turbo it up.

@hushed eagle my latest video is based on a tanstack version too! https://www.youtube.com/watch?v=vTHRmAoHCug

Nice. I've been trying to go deep on the loaders in router and start (I've a rough video demo of my own here https://discord.com/channels/1019350475847499849/1312052455055298610) but it's definitely a bit more complex. I might still be tweak in and then figure out a way to use Motion to animate the transition between routes

It might be more idiomatic to use prefetchQuery rather then useQuery without capturing the result

great video

There's a comment here on fetchQuery vs prefetchQuery #1003327027849474198 message

prefetchQuery both returns no data (it's return type is Promise<void>) and it catches errors.
