How can I delete folder on s3 with node.js?

Question

Yes, I know. There is no folder concept on s3 storage. but I really want to delete a specific folder from s3 with node.js. I tried two solutions, but both didn't work. My code is below: Solution 1: Deleting folder directly.

var key='level/folder1/folder2/'; var strReturn;         var params = {Bucket: MyBucket};         var s3 = new AWS.S3(params);         s3.client.listObjects({             Bucket: MyBucket,             Key: key         }, function (err, data) {             if(err){                 strReturn="{\"status\":\"1\"}";              }else{                 strReturn=+"{\"status\":\"0\"}";             }             res.send(returnJson);             console.log('error:'+err+' data:'+JSON.stringify(data));         }); 

Actually, I have a lot of files under folder2. I can delete single file from folder2 if I define key like this: var key='level/folder1/folder2/file1.txt', but it didn't work when I deleted a folder(key='level/folder1/folder2/'). Solution 2: I tried to set expiration to an object when I uploaded this file or folder to s3. code is below:

s3.client.putObject({                 Bucket: Camera_Bucket,                 Key: key,                             ACL:'public-read',                  Expires: 60              } 

But it didn't either. After finishing uploading, I checked the properties of that file. it showed there was nothing value for expiry date:

Expiry Date:none Expiration Rule:N/A

Answer 1

Here is an implementation in ES7 with an async function and using listObjectsV2 (the revised List Objects API):

async function emptyS3Directory(bucket, dir) {     const listParams = {         Bucket: bucket,         Prefix: dir     };      const listedObjects = await s3.listObjectsV2(listParams).promise();      if (listedObjects.Contents.length === 0) return;      const deleteParams = {         Bucket: bucket,         Delete: { Objects: [] }     };      listedObjects.Contents.forEach(({ Key }) => {         deleteParams.Delete.Objects.push({ Key });     });      await s3.deleteObjects(deleteParams).promise();      if (listedObjects.IsTruncated) await emptyS3Directory(bucket, dir); } 

To call it:

await emptyS3Directory(process.env.S3_BUCKET, 'images/')
