This is a simple quick to use wrapper for AWS SDK v3. This tool is crafted to streamline file management in the cloud, freeing up your time to concentrate on higher-priority tasks.

• Upload: Upload files and directories to S3.
• Download: Download files and directories from S3.
• Cloud transfer: Transfer files from one storage to another.
• Syncing: Ignore file if it exist, or replace only if it is newer.
• Delete: Delete files and directories from S3.
• List: List objects in an S3 directory with optional metadata.
• Meta data: Get files' metadata.

npm i s3driver

import s3driver from 's3driver';
const remote = new s3driver();

remote.config({
    accessKeyId: 'AWG7P3D8VX5Z9F21L6QC',
    secretAccessKey: 'sX9KpR4HjQ8UyL3oB6ZvA2DcP1F5TtG7IiJ2R8JqD3L4O9P2L7E8',
    endpoint: 'ams3.digitaloceanspaces.com',
    bucket: 'bucket-name',
});

(async () => {
	// Uploading directory with public-read access
	await remote.uploadDir('./test-dir', 'test-dir/');

	// Listing files, add 2nd param "true" to get full data, and not only names
	console.log('Files:', await remote.list('test-dir'));

	// Getting metadata of a file
	console.log('Files:', await remote.getMetaData('test-dir/1.txt'));

	// Deleting a file
	await remote.delete('test-dir/1.txt');

	// Deleting a dir
	await remote.deleteDir('s3driver-test-dir');
})();

For debugging messages I'm using debug

# bash shell
DEBUG=s3driver node app.js
# fish shell
env DEBUG=s3driver node app.js

    Testing

    Create file jestEnv.js in the package folder with connection data:

    process.env.ACCESS_KEY_ID="AWG7P3D8VX5Z9F21L6QC"
    process.env.SECRET_ACCESS_KEY="sX9KpR4HjQ8UyL3oB6ZvA2DcP1F5TtG7IiJ2R8JqD3L4O9P2L7E8"
    process.env.ENDPOINT="fra1.digitaloceanspaces.com"
    process.env.BUCKET="testbucket"
    

    Can run it with npm run test
