Replace an existing file

  • Policy permissions required:
    • buckets permissions: none
    • objects permissions: update and select
  • For React Native, using either Blob, File or FormData does not work as intended. Update file using ArrayBuffer from base64 file data instead, see example below.

const avatarFile = event.target.files[0]
const { data, error } = await supabase
  .storage
  .from('avatars')
  .update('public/avatar1.png', avatarFile, {
    cacheControl: '3600',
    upsert: false
  })
