{
  srcS3,
  destS3,
  srcBucket,
  destBucket,
  srcKey,
  destKey
}

Where:

srcS3 - The AWS S3 instance where the source file resides

destS3 - The AWS S3 instance where the file is to be copied

srcBucket - S3 bucket name where the source file resides

destBucket - S3 bucket name where the file is to be copied

srcKey - Source file key

destKey - Destination file key

Module assume Read access on the srcS3 credentials and write access on destS3 credentials.

const srcAWS = require('aws-sdk')
srcAWS.config.update({

  secretAccessKey: SRC_SECRET_ACCESS_KEY
})

const destAWS = require('aws-sdk')
destAWS.config.update({
  region: DEST_REGION,
  accessKeyId: DEST_ACCESS_KEY_ID,
  secretAccessKey: DEST_SECRET_ACCESS_KEY
})

const srcS3 = new srcAWS.S3()
const destS3 = new destAWS.S3()

const s3Copy = require('copy-s3-files')

s3Copy({
  srcS3: srcS3,
  destS3: destS3,
  srcBucket: SRC_BUCKET_NAME,
  destBucket: DEST_BUCKET_NAME,
  srcKey: SRC_FILE_KEY,
  destKey: DEST_FILE_KEY
}).then(function() {
  console.log('Done copying file')
