Amazon web services – I can't delete a file from AWS S3 Bucket with Javascript SDK

Then, you can use the following code to delete an object from an S3 bucket:

const AWS = require('aws-sdk');

// Configure the region
AWS.config.update({region: 'REGION'});

// Create an S3 client
const s3 = new AWS.S3();

// Define the bucket name and object key
const bucketName = 'YOUR_BUCKET_NAME';
const objectKey = 'OBJECT_KEY';

// Define the parameters for the deleteObject function
const params = {
  Bucket: bucketName,
  Key: objectKey
};

// Call the deleteObject function
s3.deleteObject(params, function(err, data) {
  if (err) {
    console.log('Error deleting object: ', err);
  } else {
    console.log('Successfully deleted object: ', data);
  }
});

Replace ‘REGION’ with the region where your S3 bucket is located, and replace ‘YOUR_BUCKET_NAME’ and ‘OBJECT_KEY’ with the name of your bucket and the key of the object you want to delete, respectively.

Make sure that the IAM role or user associated with your AWS credentials has the necessary permissions to delete objects from the S3 bucket.

If you want to delete all objects in a bucket, you can use the following code:

const AWS = require('aws-sdk');

// Configure the region
AWS.config.update({region: 'REGION'});

// Create an S3 client
const s3 = new AWS.S3();

// Define the bucket name
const bucketName = 'YOUR_BUCKET_NAME';

// Define the parameters for the listObjectsV2 function
const params = {
  Bucket: bucketName
};

// Initialize a list to store the keys of all objects in the bucket
const objectsToDelete = [];

// Call the listObjectsV2 function to get a list of all objects in the bucket
s3.listObjectsV2(params, function(err, data) {
  if (err) {
    console.log('Error listing objects: ', err);
  } else {
    // Add the keys of all objects to the objectsToDelete list
    data.Contents.forEach(function(object) {
      objectsToDelete.push({
        Key: object.Key
      });
    });

    // Define the parameters for the deleteObjects function
    const deleteParams = {
      Bucket: bucketName,
      Delete: {
        Objects: objectsToDelete
      }
    };

    // Call the deleteObjects function to delete all objects in the bucket
    s3.deleteObjects(deleteParams, function(err, data) {
      if (err) {
        console.log('Error deleting objects: ', err);
      } else {
        console.log('Successfully deleted objects: ', data);
      }
    });
  }
});
