Best way to get the type of the first argument for .query or .mutation

I am creating an abstraction in which I expect the consumer to pass the whole object that is passed as the first argument of .query or .mutation. But im not sure if there is a helper type to get this type from our instance?

"fetch failed" when building

Hi, we are running into an issue where building our production next app causes "fetch failed" errors for every page that is being generated. We have ssr set to false. How can we debug this?

standaloneMiddleware: Merge ctx/meta/input types

Using standaloneMiddleware, it would be great to merge the types (ctx, input, meta) with what is already there when passing that middleware. In our case:

experimental_standaloneMiddleware<{ ctx: { user: { id: number } } }>()

experimental_standaloneMiddleware<{ ctx: { user: { id: number } } }>()

this is because we want to be sure user.id exists in the context before allowing the usage of this middleware, but when returning like this: next({ ctx: { ...ctx, newProp: '' } }) you would still want the context type to be merged with the original so your queries and mutations get the complete context.

Do tracked properties still work when using useSuspenseQuery?

From the React Query docs:

By default, access to properties will be tracked, and the component will only re-render when one of the tracked properties change.

How would batching result in a single database query?

On the httpBatchStreamLink docs it says that multiple query calls could result in a single database query. How would that work? Should you expect the passed input to possibly be an array to allow for this?

After that, you can make use of batching by setting all your procedures in a Promise.all. The code below will produce exactly one HTTP request and on the server exactly one database query:

Have middleware require a "base" input

Is there a way to have middleware add a minimum required input, like an org id? So that every procedure with that middleware always at least gets that passed in

Why do some examples create PrismaClient in context, and others don’t

Is there a specific reason to do this or not to do this? I can imagine with the new Prisma extension feature you could do some handy things like attaching multi tenancy data to each query beforehand
