Delete Object (Node.js SDK)
Copy pageDownload PDFDelete Object (Node.js SDK)
When an object is no longer in use, you can delete it to reduce costs. The current TOS Node. JS SDK supports deleting a single object in a bucket and deleting a specified number of objects. For opening multiple versions of a bucket, you can specify to delete any version of the object's data.
Precautions
- Before deleting an object, you must have tos: DeleteObjectpermission. For details, see Access control.
- For multiple versions of buckets, you must have the tos: DeleteObjectVersionpermission before deleting the specified version object. For details, see Access control.
Sample code
Delete a specified object
The following code shows deleting the specified object from the bucket.
// Import SDK, if the TOS Node.JS SDK version is less than 2.5.2, please change "TosClient" to "TOS" in the code below.
import { TosClient, TosClientError, TosServerError } from '@volcengine/tos-sdk';
// Create a client.
const client = new TosClient({
accessKeyId: process.env['TOS_ACCESS_KEY'],
accessKeySecret: process.env['TOS_SECRET_KEY'],
region: "Provide your region", // Fill in the region where the Bucket is located. For example, if it is in China North 2 (Beijing), fill in "Provide your region" as cn-beijing.
endpoint: "Provide your endpoint", // Enter the domain address.
});
function handleError(error) {
if (error instanceof TosClientError) {
console.log('Client Err Msg:', error.message);
console.log('Client Err Stack:', error.stack);
} else if (error instanceof TosServerError) {
console.log('Request ID:', error.requestId);
console.log('Response Status Code:', error.statusCode);
console.log('Response Header:', error.headers);
console.log('Response Err Code:', error.code);
console.log('Response Err Msg:', error.message);
} else {
console.log('unexpected exception, message: ', error);
}
}
async function main() {
try {
const bucketName = 'node-sdk-test-bucket';
// The specified objectKey
const objectKey = '*** Provide your object key ***';
// Delete object
const { requestId } = await client.deleteObject({
bucket: bucketName,
key: objectKey,
});
console.log('deleteObject Request ID:', requestId);
} catch (error) {
handleError(error);
}
}
main();
Delete a specified object version
// Import SDK, if the TOS Node.JS SDK version is less than 2.5.2, please change "TosClient" to "TOS" in the code below.

try {
const bucketName = 'node-sdk-test-bucket';
// Specified objectKey
const objectKey = '*** Provide your object key ***';
// Object version corresponding to objectKey
const versionId = `*** Provide objectKey's version id ***`;
// Delete object
const { requestId } = await client.deleteObject({
bucket: bucketName,
key: objectKey,
versionId,
});
console.log('deleteObject Request ID:', requestId);
} catch (error) {
handleError(error);
}
}
main();
Batch delete objects
warning
- In the bucket with version control turned on, when the DeleteMultiObjects interface is called to delete objects in bulk, a deletion flag is inserted if versionIdis not specified in the Delete request. If versionId is specified, the specified version of the object is permanently deleted.
- The response methods supported for bulk deletion of objects can be set by quiet:
- When quietis false, it means that when the response is returned, the deletion result will be included in the response regardless of whether the object is successfully deleted or not.
- When quietis true, it means that when the response is returned, only the result of deleting the object that failed is returned, and the deletion is not considered successful.
// Import SDK, if the TOS Node.JS SDK version is less than 2.5.2, please change "TosClient" to "TOS" in the code below.

Batch delete object versions
The following code is used to delete multiple object data for the specified object name and version number in the specified bucket.
