QUESTION
As our logging mechanism is not able to create big gz-files, I'm trying to do it with a lambda. It works when I load all of them from S3 into the memory and afterwards create the gzip file. But this needs too much memory. This is why I try the following: Start a gzip stream into memory and when I receive the content of a file from S3, I write it to the gzip stream. Without luck. Besides other ideas, I tried the code below.
I read from here https://github.com/aws/aws-sdk-js/issues/2961 that the aws-sdk needs to know the length of a stream. That's why I use the streamToBuffer function which was also described on the given link.
...ANSWER
Answered 2022-Jan-11 at 17:23I finally got it working! I don't have to set the encoding for gzip but during the write. This is my code which is creating correct gzip-files:
QUESTION
Since I have fallen into the AWS trap and not ignoring the info message on the Elastic Transcoder Page saying that, we should start using Elemental MediaConverter instead, pretty much nothing is working as expected.
I have set up the Elemental MediaConvert following these steps. I have to admit that setting up everything in the console was pretty easy and I was soon able to transcode my videos which are stored on my S3 bucket.
Unfortunately, the time had to come when I was forced to do the transcoding from my web application, using the @aws-sdk/client-mediaconvert. Apart from not finding any docs on how to use the SDK, I cannot even successfully connect to the service, since apparently MediaConvert does not support CORS.
So my question is, did anyone use MediaConvert with the SDK successfully? And if yes, could you please tell me what to do?
Here is my configuration so far:
...ANSWER
Answered 2021-Nov-25 at 17:02So, after almost two entire days of trial and error plus digging into the source code, I finally found a solution! To make it short: unauthenticated access and MediaConvert will not work!
The entire problem is Cognito which does not allow access to MediaConvert operations on unauthenticated access. Here is the access list.
Since I am using Auth0 for my user authentication I was simply following this guide and basically all my problems were gone! To attach the token I was using
QUESTION
I was doing some hands on with the new SvelteKit FE using AWS Amplify to use Cognito service to authenticated my app and everything run fine in dev mode. But then, I tried to build it for deployment and this is where the fun begin...
First, I was not able to simply build the app. There was an error with Vite not able to correctly "interpret" the "browser" field!? :
...ANSWER
Answered 2021-Sep-01 at 03:54I'm not entirely sure this gets you on the right track, but one thing that has helped me out with package import weirdness, especially when it's between dev and build, is vite's optimizedDeps config directive. Perhaps something within the AWS package(s) is not liking the pre-bundling that vite is doing and you need to exclude it? This might help explain why things run fine while in dev.
QUESTION
I have created the S3 Bucket with Serverless Framework like this:
...ANSWER
Answered 2021-Jul-18 at 22:58I am confused with your explanation of your existing system (sorry!), but the general approach would be one of the following:
Using Cognito
Your back-end can use Cognito to authenticate the user and then use AssumeRoleWithWebIdentity to return a set of credentials. The user's client can then use those credentials to directly access AWS services based on the the assigned permissions.
For example, they might be permitted to access their own subdirectory in an Amazon S3 bucket, or read from a specific DynamoDB table. This can be done by sending requests directly to AWS rather than going via the back-end.
Using pre-signed URLs
If your goal is purely to grant access to private objects in Amazon S3, then instead of using Cognito, your back-end can generate Amazon S3 pre-signed URLs that provide time-limited access to private objects.
Whenever the back-end is generating a page that contains a reference to a private object (eg via tags), it can do the following:
- The app verifies that the user is entitled to access the private object by checking information in the app's database
- If the user is entitled to access the private object, the back-end generates a pre-signed URL
- The pre-signed URL is returned in the HTML page (or even as a direct link)
- When S3 receives the pre-signed URL, it verifies the signature and, if it is correct, returns the private object
The benefit of this approach is that the app can determine fine-grained access to individual objects rather than simply using buckets and prefixes to define access. This can be very useful in situations where data is shared between users (eg a photo-sharing app where users can share photos with other users) on a per-object basis.
Don't mix
In looking through your code samples, it appears that your Cognito roles are granting access to specific parts of an S3 bucket:

QUESTION
I have been playing around with the following code trying to reduce my current AWS uploader to a few lines of code. This code works great but I really need a progress indicator to monitor upload progress as for larger files or folder uploads the users has no idea how long its going to take.
I am new with promise await etc my current code uses callbacks.
I see this code here. ES6 Promise.all progress
Is it possible to get a callback for each file uploaded successfully? this way I can just get the total length of all the files to upload and output a progress based on that with an increment.
Here is my current code.
...ANSWER
Answered 2021-May-07 at 10:26You can wrap the s3.upload with your own function, as long as that returns the original response you'll have a hook into each of the promises inside the Promise.all.
QUESTION
I can find a lot of resources online on how to track upload progress to S3 using aws-sdk V2, listening to the event like:
...ANSWER
Answered 2021-Jan-15 at 14:31Looking through the github issues I've just found that @aws-sdk/client-s3 don't support upload progress tracking, since it uses fetchHttpHandler under the covers. The recommended way is to use @aws-sdk/lib-storage which I have not tried yet, but looks promising!
QUESTION
I have built applications using Firebase and React, and the procedure is pretty seamless.
Lately I have been required to use AWS Cognito, and it seems a bit of a pain to set up as the docs are not clear.
Firstly, how can I do user authentication using Cognito? I set up a user pool, with the following app client settings:
Now, I add the authorizer to my API as follows:
Now my question is, how do I use this with my frontend to sign in a user and make authenticated API calls?
There seem to be two different toolkits available:
It is not clear at all for a beginner what to use, and how to get authentication working. Ideally I would use it like I do for firebase, and just have my frontend make an authentication call using the email and password, and in turn receiving a token of some sort (on success only) that can then be used to then make signed API calls.
Can someone please help with code examples?
...ANSWER
Answered 2021-Jan-11 at 11:23sorry for the confusion.
AWS Cognito Userpools act as an Identity Provider. It supports all User management (Sign Up, Sign In, Password reset, User deletion, etc). Cognito also supports Federated Identity (E.g., A User who already has an Google/Facebook account can sign in). In this case, Cognito talks to Google/Facebook using OAuth.
When I was learning about Cognito/JWT tokens, I created a simple JS/HTML to understand how it works. Since you asked for code, you can refer it - https://github.com/ryandam9/Cognito-tokens.
As per your screen shot, you already configured a Userpool - sls-notes-backend. Say, you configured the mandatory attribute as Email.
Step 0 - Initialize You get both userPoolId and appId when you create the user pool.
QUESTION
I used CognitoIdentityServiceProvider.adminListUserAuthEvents for getting user auth events but received an invalid result. I logged in from Opera but Cognito displays that I used Chrome 8 (this is a mistake).
I could fix that if I get original navigator.userAgent (for example: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.198 Safari/537.36 OPR/72.0.3815.400), but I only received data like that:
