trying to figure AWS S3 API and failing miserably...

I currently got a bucket which consist lots of videos.

I need to request all the videos as an object, that will have the video meta-data which I set once uploading, and the link to share the video.

Problem is I'm getting the object without any of the above...

What Iv'e got so far -

AWS.config.update({accessKeyId: 'id', secretAccessKey: 'key', region: 'eu-
west-1'});
var s3 = new AWS.S3();

var params = { 
 Bucket: 'Bucket-name',
 Delimiter: '/',
 Prefix: 'resource/folder-with-videos/'

}

s3.listObjects(params, function (err, data) {
 if(err)throw err;
 console.log(data);
});

Thanks for reading :)

UPDATE - found that when using getObject and adding ExposeHeader to the CORS setting I can indeed get the metadata I set. problem is getObject only works on a specific Object (video in my case).

any Idea how I can get all the object like listObject and have values of each object like I do on getObject?

Only solution I can think of is doing listObject to get a list of all the objects, and then by this result to do for each object an getObject ajax?... rip UX thanks :)
