Async upload AWS S3?

Question

Amazon Web Services

Hello.
There is a need to download a picture, upload it to AWS S3, then delete it.
If you don't have to download it, it would be great to keep it in memory or something like that...
This is an example of a controller for koajs.
In the response back, of course, I want to give a link to the file on S3.

exports.updatePhoto = async function (ctx) {
    let url = 'http://cs8.pikabu.ru/post_img/2017/06/23/8/149822058719807864.jpg';
    let timestamp = + new Date();
    let filename = config.aws.userFolder + '/' + timestamp + '.png';

    await request(url).pipe(fs.createWriteStream('test.png'));

    let read = await fs.createReadStream('test.png');
    let upload = s3Stream.upload({
        'Bucket': config.aws.bucketName,
        'Key': filename
    });

    upload.on('error', function (error) {
        console.log('ERROR');
        console.log(error);
        ctx.body = {error: error};
    });

    upload.on('uploaded', function (details) {
        console.log('DONE');
        console.log(details);
        ctx.body = {url: details.Location};
    });

    await read.pipe(upload);

    // await fs.unlink('test.png', function(err) {
    //     console.log(err);
    // });

    ctx.body = 'Hello';
};
