How to upload files directly to AWS using AngularJS and the AWS JS SDK

@binoculars The reason there is a callback option is because the getSignedUrl method will asynchronously refresh credentials if they are expired. Calling getSignedUrl without a callback will return the url directly, but this can be unsafe if your credentials can expire.. I agree that we should also allow for getSignedUrl to return a promise. The way this currently works for other operations is that the request object returned by an operation can then have promise() called on it.getSignedUrl GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together Example browser script that shows how to view and manipulate photo albums and photos in Amazon S3 buckets.

Surprisingly, apart from using the AWS CLI, I didn't find any proper Node.js script or an app that would do this for medium to large scale buckets using the AWS-SDK. The answers I found on Node.js posts online had several problems, including half-baked scripts, scripts that would try and synchronously create a file and would not know when to complete and also would ignore cloning empty folders if there was any. Basically, it didn't do the job right. Hence decided to write one myself, properly.

If you download one file at a time (basically run the code above with 1 concurrent download serially for each file), that should be pretty safe. However, if you have a lot of small files and/or light compression, this will probably be quite a bit slower. If you have large files and/or heavy compression, I would guess it would not be much slower. So there you have it! That's how you Upload and Get Images from Amazon S3 with NodeJS.

AWS.S3 methods documentation The scenario we’re going to build for here will be to upload a file (of any size) directly to AWS S3 into a temporary bucket that we will access using a restricted and public IAM account. The purpose of this front end application will be to get files into AWS S3, using only JavaScript libraries from our browser. Surprisingly, apart from using the AWS CLI, I didn't find any proper Node.js script or an app that would do this for medium to large scale buckets using the AWS-SDK.

Rather than sending the large file through your application's servers, the client can upload the file directly from the browser via tightly-scoped permissions. Imagine I want to allow a user to upload a file to my cloudberry-examples bucket with the key name of uploads/image.jpg. In

Using that URL opens the file even for anonymous users. How does it work? This works by signing an operation, in this case, this is the S3 getObject with the bucket and the object key as parameters. You can sign other operations too, for example PUT allows uploading new objects.. If you look at the URL, you can find the Access key, but the Secret key is only used to generate the Signature part. Lambda Functions The first thing I found out was that I could use AWS Lambda to sort of outsource computations that might normally take place on a server. As a bonus, since I was already using S3, I could attach what amounts to an event listener to trigger my Lambda function when I uploaded a video file.. Creating a new Lambda function is straightforward. When prompted you want to chose create a function from scratch and come up with a decent name; createThumbail worked for me. Also, select @vkovalskiy to answer your question specifically, you can theoretically generate signed URLs for multipart uploads, but it would be fairly difficult to do. You could initiate the multipart upload on the backend on behalf of the user, but you would have to generate signed URLs for each individual uploadPart call, which would mean having to know exactly how many bytes the user was uploading, as well as keeping track of each ETag from the uploadPart calls that the user sends so that you can Simple File Upload Example.

All this data is ingested through your web server(s), which you then have to scale — if you’re lucky this means auto-scaling in AWS, but if you’re not in the cloud you’ll also have to contend with the physical network bottleneck issues.

I was googling it, but couldn't find any resources tha In a Node.js project, I am attempting to get data back from S3.

I believe I am just using it incorrectly. This is what I've tried The AWS SDK for JavaScript enables you to directly access AWS services from JavaScript code running in the browser.
