Creating a signed S3 URL with Javascript

Question

I am attempting to create a signed S3 URL using Javascript & NodeJS. I have used this specification.

var crypto     = require(\'crypto\'),
    date       =          


        

Answer 1

My implementation using AWS-SDK and Rx.

import AWS from "aws-sdk"
import Rx from 'rx'

/*
* Credentials could be loaded from env variables
* http://docs.aws.amazon.com/sdk-for-javascript/v2/developer-guide/loading-node-credentials-environment.html
* */

const s3 = new AWS.S3({apiVersion: '2006-03-01'});

export function getS3SignedImage(objectKey) {
    return Rx.Observable.create(function (observer) {
        s3.getSignedUrl('getObject',{
            Bucket: process.env.AWS_BUCKET,
            Key: objectKey
        }, (err, data) => {
            if (err) {
                return observer.onError(err);
            }
            observer.onNext(data);
            observer.onCompleted();
        });
    });
}
