Javascript to download a file from amazon s3 bucket?

Question

I was trying to download a file from a bucket on Amazon S3. I was wondering if I can write a javascript to download such a file from a bucket. I was googling it, but couldn't find any resources that can help me do that.

Some steps in mind are: authenticate Amazon S3, then by providing bucket name, and file(key), download or read the file so that I can be able to display the data in the file.

Thanks,

Maybe you can use AWS Node.js API:

var AWS = require('aws-sdk');
AWS.config.update(
  {
    accessKeyId: ".. your key ..",
    secretAccessKey: ".. your secret key ..",
  }
);
var s3 = new AWS.S3();
s3.getObject(
  { Bucket: "my-bucket", Key: "my-picture.jpg" },
  function (error, data) {
    if (error != null) {
      alert("Failed to retrieve an object: " + error);
    } else {
      alert("Loaded " + data.ContentLength + " bytes");
      // do something with data.Body
    }
  }
);
