why this else sir? from what i can see you are returning the same thing

videoUrl is diff in both the case. there was already an implementation for type == 'video'. I do not want to break that. plus control will not go inside if in case of folder because parent will be null.

@siinghd let me know if you feel some changes is required.

also, rn in production user can create same bookmark multiple time. creating multiple entry of same contentId. I think we should change the schema of bookmark to

model Bookmark {
  id        Int      @id @default(autoincrement())
  userId    String
  contentId Int
  user      User     @relation(fields: [userId], references: [id], onDelete: Cascade)
  content   Content  @relation(fields: [contentId], references: [id])
  createdAt DateTime @default(now())

  @@unique([userId, contentId])
} 

here is a script to delete multiple records then we can do prisma migrate.

import { PrismaClient } from '@prisma/client'

const prisma = new PrismaClient()

async function deduplicateBookmarks() {
  console.log('Starting deduplication process...')

  const allBookmarks = await prisma.bookmark.findMany({
    select: {
      id: true,
      userId: true,
      contentId: true,
    },
    orderBy: {
      createdAt: 'asc',
    },
  })

  console.log(`Total bookmarks found: ${allBookmarks.length}`)

  const uniqueCombinations = new Set()
  const duplicateIds = []

  for (const bookmark of allBookmarks) {
    const key = `${bookmark.userId}-${bookmark.contentId}`
    if (uniqueCombinations.has(key)) {
      duplicateIds.push(bookmark.id)
    } else {
      uniqueCombinations.add(key)
    }
  }

  console.log(`Duplicate bookmarks found: ${duplicateIds.length}`)

  if (duplicateIds.length > 0) {
    const deleteResult = await prisma.bookmark.deleteMany({
      where: {
        id: {
          in: duplicateIds,
        },
      },
    })

    console.log(`Deleted ${deleteResult.count} duplicate bookmarks`)
  } else {
    console.log('No duplicates found')
  }

  console.log('Deduplication process completed')
}

deduplicateBookmarks()
