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
  })
