Javascript code to download a file from Amazon S3

Question

Is there a javascript code to download a file from Amazon S3? I couldn't find anything useful resources on the internet. So, if any of you have done something similar to this can you post the code?  Well, is it possible to write a javascript code to download a file from S3?

Answer 1

Hai, I was thinking along the same lines. Then I figured out I could make use of node.js, ie. use AWS SDK for javascript in node.js.

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");
    }
  }
);

Try this out!

Hope this helps!!

Hi Prashanth,

To run your script on the client-side, you need to use some automation tools. Generally in this type of use case, we use Terraform. But we can also use the Ansible playbook to do this task.
