updateCredentials(credentials)

Sometimes we want to set our AWS credentials dynamically.

In that senario we can use updateCredentials() to set the credentials on the fly

	const credentials = {
		accessKeyId:'your-aws-access-key',
		secretAccessKey:'your-aws-secret-key'
	};
	updateCredentials(credentials)

updateRegion(region)

Setting our S3 region on the fly

	updateRegion('ap-south-1')

updateBucketName(bucketName)

Setting our S3 region on the fly

	updateBucketName('new-bucket-name')

TODO

• Handle Missing credentials errors
• File Upload Progress
