Question

I want to delete AWS S3 Object according to the time of creation using Nodejs Lambda function. I want to delete all objects in a particular folder which are created before 24 hour
Now I have tried to delete multiple object which is success but I dnt know how to do it with time

var params = {
      Bucket: s3bucket, 
      Delete: { 
        Objects: [ 
          {
            Key: 'scheduled_lambda_test/1.png' 
          },
          {
            Key: 'scheduled_lambda_test/2.png' 
          }
        ]
      }
    };

s3.deleteObjects(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

You can use node sdk and perform below operations

1. use listObject action on your folder.

2. Loop through all the object returned for that folder and check last modified date.

3. If object is expired add object key to an array.

4. Delete all the object in expired array
