AWS Javascript/Typescript SDK download s3 file

I would like to use the AWS Javascript SDK to download a file from s3.

My current code is

import {
    S3Client,
    GetObjectCommand,
} from "@aws-sdk/client-s3";

const s3 = new S3Client({region: REGION});


const downloadParams = {Bucket: bucketName, Key: keyName};

const downloadFile = async () => {
    try {
        const data = await s3.send(new GetObjectCommand(downloadParams));
        // fs.writeFileSync("output.txt", data.Body);
        // fs.writeFile("output.txt", data.Body);
        console.log("Success, bucket returned", data);
    } catch (err) {
        console.log("Error", err);
    }
}
downloadFile();

But I am not sure how to get the file data from the return data.

Data.body does not get the file data.

Please refer to this JS example in the AWS Github repo. It shows you how to get the object from the Amazon S3 bucket. It is returned as a ReadableStream.
