upload()

Signature

massi.storage.from(bucket: string).upload(
  key: string,
  file: Blob,
  opts?: { contentType?: string }
): Promise<{ data: StorageObject | null; error: MassiCloudError | null }>

Example

const file = fileInput.files[0] // a Blob/File from an <input type="file">

const { data, error } = await massi.storage
  .from('avatars')
  .upload('users/42/photo.txt', file)

Notes

• Requires a signed-in end user — massi.auth.signIn() first. Anonymous uploads are rejected even on public buckets.
• key sets the full object path, including any folder-like prefix (users/42/photo.txt).
• opts.contentType overrides the file’s own MIME type if you need to set it explicitly.
