Get uploaded object URL with Javascript 'aws-sdk' v3

Question

Currently, we are using aws-sdk v2, and extracting uploaded file URL in this way

  const res = await S3Client
    .upload({
      Body: body,
      Bucket: bucket,
      Key: key,
      ContentType: contentType,
    })
    .promise();

  return res.Location;

Now we have to upgrade to aws-sdk v3, and the new way to upload files looks like this

const command = new PutObjectCommand({
  Body: body,
  Bucket: bucket,
  Key: key,
  ContentType: contentType,
});

const res = await S3Client.send(command);

Unfortunately, res object doesn't contain Location property now.

getSignedUrl SDK function doesn't look suitable because it just generates a URL with an expiration date (probably it can be set to some extra huge duration, but anyway, we still need to have a possibility to analyze the URL path)

Building the URL manually does not look like a good idea and a stable solution to me.

Answer 1

Answering myself: I don't know whether a better solution exists, but here is how I do it

const command = new PutObjectCommand({
  Body: body,
  Bucket: bucket,
  Key: key,
  ContentType: contentType,
});

const [res, region] = await Promise.all([
  s3Client.send(command),
  s3Client.config.region(),
]);

const url = `https://${bucket}.s3.${region}.amazonaws.com/${key}`
