Replace an existing file

Replaces an existing file at the specified path with a new one.

  • RLS policy permissions required:
    • buckets table permissions: none
    • objects table permissions: update and select
  • Refer to the Storage guide on how access control works
  • 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.
Parameters
  • path
    REQUIRED
    string

    The relative file path. Should be of the format `folder/subfolder/filename.png`. The bucket must already exist before attempting to update.

  • fileBody
    REQUIRED
    object

    The body of the file to be stored in the bucket.

  • fileOptions
    Optional
    FileOptions

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