How to reduce cold start times with tRPC api
My app was built using t3 stack and for the most part its great but it has one problem that i havent been able to solve / understand yet. Currently, my tRPC api has a ~10s or so cold start time in my vercel deployment. When the api isnt cold starting the api requests take a second or 2. This is ruining demos whenever I try to show people. Here are the things I know / figured out:
- The cold start time is only bad for api requests. The UI never seems to have a problem loading quickly.
- Vercel's function logger shows the Init Duration as > 7s
- Online i've seen people complaining about 1-2 second cold start times so i feel like i must be doing something totally wrong...

Easy way to clear database?
Noob here. My schema is massive and I don't want to have to manually type in all of my model names + deleteMany().
Doing that is also painful because a lot of times you have to delete things in a certain order.
I'm using prisma db push instead of migrations.
Anyone have an easy ts code snippet that will just completely wipe my database so I can seed everything again?...
NextAuth + GitHub Provider refresh
is anyone using NextAuth with the GitHub provider in a real app?
From what I understand, sessions don't get renewed properly after a few hours unless you make some changes, see:
- https://next-auth.js.org/providers/github
- https://docs.github.com/en/apps/creating-github-apps/authenticating-with-a-github-app/refreshing-user-to-server-access-tokens#response

...NextAuth - User stays logged in after token is expired
Right, I understand that maybe I should write some sort of callback or something that prompts the user to log in again, or maybe to refresh the token.. but I don't understand why this happens.
React-Dropzone, useState & dnd-kit struggles
What I want to achieve is the ability to drag image previews to change the order of the images, ie. something like this: https://codesandbox.io/s/dndkit-sortable-image-grid-py6ve?file=/src/App.jsx
The images & their preview come from a react-dropzone component. There is a solid chance this is irrelevant to my issue but mentioning it to be sure.
My initial plan was to have a state in the react-dropzone component inside of the
onDrop: that will populate the useState into the following shape: { id: number, src: File }. This approach is similar to the example in the first codesandbox. but I don't see how I can do this without a useEffect, which feels overkill since this is really close to what I want to achieve: https://github.dev/HamedBahram/dropzone...Export a Planetscale database.

TRPC useQuery keeps refetching when switching pages? How can I cache the data on the client?
I recently migrated my project from CRA + React Query to T3 stack.
I'm finding that on my client, all my queries called using useQuery are not being cached correctly. The whole React Query cache gets wiped when I go to a different page. In CRA this wasn't an issue, the query was cached until I invalidated it or it ran out of cache time.
I'm not sure if there's an option I need to pass to the useQuery calls?...

How to replicate React Router Outlet like utility for Next.js?
A module in my Next.js application has a sidebar. I want to navigate to those paths without re-fetching the same data (that belongs to the parent component) from the API. The routing system of Next.js is restricting me to achieve the same. Is there any way I can replicate react-router "Outlet" like utility in Next.js?
Thanks!...
pre-defining data in SSR?
Curious — can you use NextJS middleware to push data into getServerSideProps? Let’s say you have some global variable that gets reset every page refresh — but you need to populate through some API or pass it from the client. What’s a good way to populate the server with that global variable before it reaches a pages SSR
