Get file properties
You can get file properties and metadata without downloading the file
getProperties
import { getProperties } from 'aws-amplify/storage';
try { const result = await getProperties({ path: 'public/album/2024/1.jpg', // Alternatively, path: ({identityId}) => `protected/${identityId}/album/2024/1.jpg` }); console.log('File Properties ', result);} catch (error) { console.log('Error ', error);}import { getProperties } from 'aws-amplify/storage';
try { const result = await getProperties({ key: 'album/2024/1.jpg', options: { accessLevel: 'guest', // defaults to `guest` but can be 'private' | 'protected' | 'guest' targetIdentityId: 'xxxxxxx' // ID of another user, if accessLevel is `protected` } }); console.log('File Properties ', result);} catch (error) { console.log('Error ', error);}The properties and metadata will look similar to the below example
