Supabase

createSupabaseAdapter uploads directly to Supabase Storage.

import { createSupabaseAdapter } from "../components/DropUpload"

const adapter = createSupabaseAdapter({
  url: "https://your-project.supabase.co",
  bucket: "uploads",
  getToken: () => process.env.NEXT_PUBLIC_SUPABASE_ANON_KEY!,
})

<DropUpload uploadAdapter={adapter} />

• getToken can return the anon key for public buckets, or a user's JWT for buckets governed by row-level security policies.
• Files are uploaded to a timestamp-prefixed path ({Date.now()}-{filename}) to avoid collisions; existing objects at that path are overwritten unless you pass upsert: false.
• The adapter resolves with the object's public URL — only usable if the bucket (or the specific object) is public.
