Building shadcn <Form> components for string arrays?

So I know it uses react-hook-form under the hood, but I'm struggling to figure out the best pattern for building the form for an array. Say I had a form schema like this:

const formSchema = z.object({
  socials: z.array(z.string()),
});

const formSchema = z.object({
  socials: z.array(z.string()),
});

I want to create multiple <Input /> components that should each correspond to a certain element in the "socials" array, but how would this work using shadcn <Form> components? This doesn't work, it throws an error saying "expected array, received string"

<FormField
  control={form.control}
  name="socials"
  render={({ field }) => (
    <FormItem>
      <FormLabel className="sr-only">Create post</FormLabel>
      <FormControl>
        {/* I want these inputs to correspond to each element in the array, how do I achieve this? */}
        <Input
          {...field}
        />
        <Input
          {...field}
        />
        <Input
          {...field}
        />
      </FormControl>
      <FormDescription className="sr-only">
        Paste in your Spotify link
      </FormDescription>
      <FormMessage />
    </FormItem>
  )}
/>

<FormField
  control={form.control}
  name="socials"
  render={({ field }) => (
    <FormItem>
      <FormLabel className="sr-only">Create post</FormLabel>
      <FormControl>
        {/* I want these inputs to correspond to each element in the array, how do I achieve this? */}
        <Input
          {...field}
        />
        <Input
          {...field}
        />
        <Input
          {...field}
        />
      </FormControl>
      <FormDescription className="sr-only">
        Paste in your Spotify link
      </FormDescription>
      <FormMessage />
    </FormItem>
  )}
/>

Best practice for providing current user from db to all react components?

So I know that various auth providers have hooks like useUser() or useSession() which you can use to access their user object in components, but I have a users table where each user has an extensive amount of data describing them. I personally use supabase with the T3 stack, and I don't want to copy all this data to the "user_metadata" that supabase provides just to have the useUser() functionality. So my question is: what's the best practice for providing current user data (from the users table in db) to all react components for the purpose of stuff like conditional rendering? (I've thought about state management solution, or just plain old useContext(), but then how would you trigger refetches when the user changes something?)

Alternative to Clerk for cross-platform app (Next.js / React Native + Expo)

I’m looking to build a cross-platform app (web + mobile) and I love the DX that comes with the t3 stack. Ive seen the turborepo templates but one major issue sticks out to me: create-t3-turbo doesn’t seem to have an auth solution for RN + Expo, and the other template forces the use of Clerk. Yes Clerk is a great product, but their pricing is insane for anything consumer-focused (lots of MAUs) so what are some viable alternatives for handling auth across web + mobile?

tRPC SSG Helper w/ new Clerk middleware

So my goal is to do almost exactly what Theo does in his tutorial using the SSG helper for profile pages, but due to updated Clerk middleware I had to change my trpc.ts file. I have my trpc.ts file set up identical to this: https://github.com/perkinsjr/t3-app-clerk-minimal/blob/main/src/server/api/trpc.ts There is a comment in there that says:

/**
 * This helper generates the "internals" for a tRPC context. If you need to use
 * it, you can export it from here
 *
 * Examples of things you may need it for:
 * - testing, so we dont have to mock Next.js' req/res
 * - trpc's `createSSGHelpers` where we don't have req/res
 * @see https://create.t3.gg/en/usage/trpc#-servertrpccontextts
 */

/**

 * it, you can export it from here
 *

 * - trpc's `createSSGHelpers` where we don't have req/res
 * @see https://create.t3.gg/en/usage/trpc#-servertrpccontextts
 */

But I can't figure out how to use the "auth" object in the context when defining the SSG helper, it's always erroring when I try to set it up:

import { createServerSideHelpers } from "@trpc/react-query/server";
import { appRouter } from "~/server/api/root";
import { prisma } from "~/server/db";
import superjson from "superjson";


export const generateSSGHelper = () =>
  createServerSideHelpers({
    router: appRouter,
    ctx: { auth, prisma }, // auth errors here saying: No value exists in scope for the shorthand property 'auth'. Either declare one or provide an initializer.ts(18004)
    transformer: superjson,
  });

import { createServerSideHelpers } from "@trpc/react-query/server";
import { appRouter } from "~/server/api/root";
import { prisma } from "~/server/db";
import superjson from "superjson";


export const generateSSGHelper = () =>
  createServerSideHelpers({
    router: appRouter,
    ctx: { auth, prisma }, // auth errors here saying: No value exists in scope for the shorthand property 'auth'. Either declare one or provide an initializer.ts(18004)
    transformer: superjson,
  });

How to create debounce search with tRPC

So I'm aware that react-query provides a useDebounce hook but I guess tRPC doesn't wrap around this - so I'm wondering, what is the optimal way to create a simple search bar function with tRPC? If I have something like this:

const { data } = api.users.getById.useQuery({ id });

const { data } = api.users.getById.useQuery({ id });

How do I add debouncing functionality so that the query only fires after a set time interval? As far as I can tell, tRPC queries fire instantly unless you set the

enabled

enabled

property, but that only accepts a boolean.

How to use Prisma model type in tRPC mutation w/ Zod

I have some models defined in my schema.prisma file. Let's say they look like this:

model Art {
  id        String @id @default(cuid())
  // Some other fields
  creators Creator[]
}

model Creator {
  id        String @id @default(cuid())
  creatorId String
  artId    String
  art      Art   @relation(fields: [artId], references: [id])
}

model Art {
  id        String @id @default(cuid())
  // Some other fields
  creators Creator[]
}

model Creator {
  id        String @id @default(cuid())
  creatorId String
  artId    String
  art      Art   @relation(fields: [artId], references: [id])
}

I am using a tRPC mutation to create an "Art" in my Planetscale database. So, since I'm using Zod, I am doing something like this:

create: privateProcedure
    .input(
      z.object({
        // Some other fields
        creators: (this is where I'm confused)
      })
    )
    .mutation(async ({ input }) => {
      const artistId = ctx.userId;

      const art = await ctx.prisma.art.create({
        data: {
          // Some other fields
          creators: input.creators,
        },
      });

      return art;
    }),

create: privateProcedure
    .input(
      z.object({
        // Some other fields
        creators: (this is where I'm confused)
      })
    )
    .mutation(async ({ input }) => {
      const artistId = ctx.userId;

      const art = await ctx.prisma.art.create({
        data: {
          // Some other fields
          creators: input.creators,
        },
      });

      return art;
    }),

I know I can get the Creator type from Prisma, but I don't know how to tell Zod to expect those properties as the input so that the tRPC procedure will run. I hope I'm explaining this ok because it's kinda hard to put into words lol

Clerk - can’t get types of unsafeMetadata properties on user object?

I have some unsafeMetadata stored on the user object for users in my t3-app. When I try to access any property of the object, TypeScript seems unable to get/infer the type of that property. So for example: user.unsafeMetadata.stringProperty should be a string but it comes back as unknown. Is this a known issue or am I not doing something right?

tons of eslint errors in vercel builds that don’t show up in dev

I haven’t changed the default eslint config file that comes out the box with create-t3-app. Whenever I deploy to vercel, the builds always exit with many @typescript-eslint/… errors that I just don’t see anywhere during development. Anyone know how to fix this so that these errors show up during development and on local host?

File storage with T3

Hey so someone asked this before but it was half a year ago so I’m interested in seeing if things have changed: I’m looking for a cloud-based file storage option for storing image and audio files for my app. Metadata for both will be stored in Planetscale but I need something for the actual files. What do you guys recommend?
