How to create a tiddler from json inside javascript macro

[Justin B]

Hello everyone, 

This is my first time posting so please let me know if there is additional context or conventions I should be providing. 

I am trying to retrieve a json object in the format they are imported and exported by TiddlyWiki from AWS S3 and then create a tiddler with the response. I am new to Javascript and am very open to suggestions for other improvements. 

My code which successfully retrieves the object and writes the json to the console is as follows: 

```

(function(){

"use strict";

exports.name = "getobject";

exports.params = [

{key: ""}

];

exports.run = function(key) {

  

function handleresult(err, data) {

            if(err)throw err;

            console.log(data.Body.toString('utf-8'));

// Make a tiddler out of data.Body.toString('utf-8') here

return data

}

AWS.config.update({

  accessKeyId: 'MyAccessKey', 

  secretAccessKey: 'MySecretKey', 

  region: 'us-east-2'

});

var s3 = new AWS.S3();

var params = { 

 Bucket: 'testtiddlybucket',

 Key: key

}

var result = s3.getObject(params, handleresult);

return "Results from list objects call with prefix " + result

};

})();

```

Is there a Javascript macro I can call to implement the Tiddler creation? 

Thanks in advance!
