Notes#

  • RLS policy permissions required:
    • buckets table permissions: none
    • objects table permissions: insert
  • Refer to the Storage guide on how access control works
  • For React Native, using either Blob, File or FormData does not work as intended. Upload file using ArrayBuffer from base64 file data instead, see example below.

Examples#

Upload file#

1const avatarFile = event.target.files[0]
2const { data, error } = await supabase
3  .storage
4  .from('avatars')
5  .upload('public/avatar1.png', avatarFile, {
6    cacheControl: '3600',
7    upsert: false
8  })

Upload file using ArrayBuffer from base64 file data#

1import { decode } from 'base64-arraybuffer'
2
3const { data, error } = await supabase
4  .storage
5  .from('avatars')
6  .upload('public/avatar1.png', decode('base64FileData'), {
7    contentType: 'image/png'
8  })
