Calculating average rating across a large dataset

Hello! I'm currently looking to build a feature that shows the average rating of a show based on entry logged by users. This is my first time approaching something like this Convex. I was wondering if there were any recommended solutions? I was looking into the Aggregate convex component to potential solve my problem. The only issue I've have with that approach is that a user can log an entry without rating it, but the sameValue does not accept undefined.

export const animeStatsByEntry = new TableAggregate<{
  Namespace: Id<'anime'>
  Key: null
  DataModel: DataModel
  TableName: 'anime_entries'
}>(components.aggregateByAnime, {
  namespace: doc => doc.animeId,
  sortKey: _ => null,
  // TODO: This needs to ignore undefined values instead of setting them to 0
  sumValue: doc => doc.rating ?? 0
})

export const animeStatsByEntry = new TableAggregate<{
  Namespace: Id<'anime'>
  Key: null
  DataModel: DataModel
  TableName: 'anime_entries'
}>(components.aggregateByAnime, {
  namespace: doc => doc.animeId,
  sortKey: _ => null,
  // TODO: This needs to ignore undefined values instead of setting them to 0
  sumValue: doc => doc.rating ?? 0
})

useQuery different return types

Hello, I'm fetching data with useQuery and for some reason it has two different return types. In one component it returns an object with the data, error, etc properties while in the other it only returns the data. returns entry type | null | undefined

const entry = useQuery(api.functions.anime_entries.authSingleById, {
   id: media._id
 })

const entry = useQuery(api.functions.anime_entries.authSingleById, {
   id: media._id
 })

returns an object with data about the query as well

const { data: lists, error: listError } = useQuery(
  api.functions.lists.authAll,
  {}
)

const { data: lists, error: listError } = useQuery(
  api.functions.lists.authAll,
  {}
)

Best way of querying documents when using Clerk

Hello! I'm currently working on a project that uses both Convex and Clerk together. I've been running into some issues with consistency within my backend when it comes to query documents by id and wanted to see if anyone had advice. The problem is that it's easy and convenient to query by a user's Clerk id, but I lose the type safety of the _id prop. It also leads to weird situations when creating relationships between tables. Should I just my me query function (returns user info protected by auth RLS) every time I want to query with a user id or is using the clerkId as the primary way of fetching a document a ok practice? me function

export const me = authRLSQuery({
  handler: async ctx => {
    const user = await getUser(ctx, ctx.identity.subject)
    if (!user) {
      throw new ConvexError({ message: 'No user found for this identifier' })
    }
    return user
  }
})

export const me = authRLSQuery({
  handler: async ctx => {
    const user = await getUser(ctx, ctx.identity.subject)
    if (!user) {
      throw new ConvexError({ message: 'No user found for this identifier' })
    }
    return user
  }
})

utils

export async function getUser(ctx: QueryCtx | MutationCtx, clerkId: string) {
  const user = await ctx.db
    .query('users')
    .withIndex('by_clerkId', q => q.eq('clerkId', clerkId))
    .first()
  return user
}
export const authRLSQuery = customQuery(query, {
  args: {},
  input: async (ctx, args) => {
    const identity = await ctx.auth.getUserIdentity()
    if (!identity) {
      throw new ConvexError({
        code: 'UNAUTHORIZED',
        message: 'Sorry, you must be logged in to perform this action'
      })
    }

    const db = wrapDatabaseReader({ identity }, ctx.db, {
      users: {
        read: async (ctx, user) => ctx.identity.subject === user.clerkId
      }
    })
    return { ctx: { ...ctx, db, identity }, args }
  }
})

export async function getUser(ctx: QueryCtx | MutationCtx, clerkId: string) {
  const user = await ctx.db
    .query('users')
    .withIndex('by_clerkId', q => q.eq('clerkId', clerkId))
    .first()
  return user
}

        message: 'Sorry, you must be logged in to perform this action'
      })
    }

    const db = wrapDatabaseReader({ identity }, ctx.db, {
      users: {
        read: async (ctx, user) => ctx.identity.subject === user.clerkId
      }
    })
    return { ctx: { ...ctx, db, identity }, args }
  }
})

ip whitelist with httpRouter

Hello, I'm currently using the httpRouter with Clerk webhooks to sync events with convex. I was wondering if there was a easy way to setup an ip whitelist so any requests that aren't from a specific ip list are dropped?

Implementing non OpenID custom auth

Hello, I have a website that requires dual auth provider sign ins for a valid session. Previous I would do this with supabase by using their JWT secret to sign my session cookie. This allowed supabase auth to work with my custom authenication system. I was wondering if there was a similar way to do this with Convex?

preloaded data with paginated query

Hello, I was wondering if there was an official way of preload loading data for a paginated query in nextjs? With regular queries I can just use the usePreloadedQuery() hook, but I don't see an equivalent for paginated queries.

Adding typing to ConvexError data field without casting everytime

Hello! I was using ConvexError and following the docs on adding custom data to the data field of ConvexError. The docs recommended casting for getting the correct typings, but I feel this would be a bit cumbersome. Is there any better way to do this?
