NextJS dynamic routes with „use cache“ and dynamicIO - examples?

Hi everyone 😃 Does anyone have an example with an cached dynamic route in the new dynamicIO way of doing it? Even though I saw an issue on GitHub, I can’t believe it’s in general not possible. I basically need a very common example for something like a blog....

Problem with t3 chat pro

I bought it yesterday, and I do get quite a lot of 'Stream failed for unknown reasons' or 'Uncaught exception' errors. After it encounters an uncaught exception, there is no way to recover that particular chat—you have to create a new one. Here is an example

I have magic link auth and google oauth. I need to create default team in db for user when user signups but before he redirected to dashboard. What would be appropriate place to do it?

Solution:

found it. events.createUser . i though this event executed asynchoniously but it is actully awaited in auth flow so user is blocked while team is being created

T3 Chat Temp Chat Feature

I was thinking of buying T3 chat and was wondering if they had a temporary chat feature, that works like a incognito chrome tab. Was wondering if this was a feature and if it wasn't if it would be added in the future.

Next js server actions

Hi, its my first time using server actions, i always use an api and make requests using react query, So I'm used to handling query invalidations, through react query, and now using actions, to simplify my code base, since it's a very simple project, would this be the best way to update data after removing files? by the way, does the code structure look correct?

trpc with nextjs 15

Does it makes sense using trpc with nextjs 15? Because there is server actions too but that's not type safe.

Struggling to Reduce Vercel Function Invocations on My Next.js Website – Need Optimization Tips!

I'm building a website using Next.js, Prisma, and MongoDB, but I'm encountering an issue with excessive Vercel Function Invocations. On a private Vercel account, I noticed that a single request can trigger anywhere from 19 to 100 function invocations, which feels extreme. I've already tried batching requests, server-side caching, and Incremental Static Generation (ISR), but the improvements are minimal. Does anyone have experience optimizing server-side actions for medium to large-scale projects? How can I effectively consolidate these invocations without sacrificing functionality? Any advice, strategies, or resources would be greatly appreciated! I am including stats from my Vercel Account where the app was hosted. I have paused the project because I don't want to end up homeless before AI takes my job....

UT Download Speed question.

So I've noticed that hosted files on UT are downloading quite slowly, or at least slower than I thought. For example, a 150kb image sometimes takes 2 seconds to download or longer. I wonder why this is. I am assuming it has to do with some configuration mistake I made. I'm using "Frankfurt, Germany" region. Can someone advise? I don't even know how to start diagnosing the issue......

"Favourite"/Pinned replies on t3.chat

Hi all! I recently subscribed to t3.chat and while I watch the stream when I can (UK timezone, sadly) - i'm not sure if there is a place to ask about t3.chat or recommend. Do you think it could be possible to add a 'pin' to t3.chat replies, similar to the pinned posts in Discord?...

Solution:

That's a good feature that I'm looking forward too! The T3 Chat channel is #t3-chat, although in order to always see it in the sidebar I had to right click on it and select add to channel list.
