Parse stream to object in Nodejs

I am trying Get an object from Amazon S3 storage in Node.Js.

And this perfectly works when I am saving it to a file.

amazon.getObject = function () {

    var options = {
        BucketName : 'mybucket',
        ObjectName : 'path/to/my.json',
        ResponseContentType : 'application/json'
    };

    s3.GetObject(options, function(err, data) {
        var fs = require('fs');
        var fd = fs.openSync('helloaa.json', 'w+');
        fs.writeSync(fd, data.Body, 0, data.Body.length, 0);
        fs.closeSync(fd);
    });

};

In. helloaa.json is:

{
    "hello": 1,
    "world": 3
}

But. I don't want to write data to file on my disk.

I want parse this json to object with JSON.parse();

When I print object there with:

    s3.GetObject(options, function(err, data) {
        console.log(JSON.stringify(data));
    });

In console is this:

{"StatusCode":200,"Headers":{"x-amz-id-2":"N1gDLPam+fDCLWd9Q2NI62hizH7eXAjg
61oLYOkanLoSlqUlDl6tqasbfdQXZ","x-amz-request-id":"C53957DAF635D3FD","date"

9":34,"10":58,"11":32,"12":49,"13":44,"14":10,"15":32,"16":32,"17":32,"18":

What is it?

How can I parse it?

Is it stream?

Can I save stream to object in NodeJs?

Have you tried data.Body.toString()?


I had to parse the JSON after converting to string:

    var fileContents = data.Body.toString();
    var json = JSON.parse(fileContents);
    console.log(json);
