How to Get Signed S3 Url in AWS-SDK JS Version 3? - amazon-web-services

Question

I am following the proposed solution by Trivikr for adding support for s3.getSignedUrl api which is not currently available in newer v3. I am trying to make a signed url for getting an object from bucket.
Just for convenience, the code is being added below:
const { S3, GetObjectCommand } = require("#aws-sdk/client-s3"); // 1.0.0-gamma.2 version
const { S3RequestPresigner } = require("#aws-sdk/s3-request-presigner"); // 0.1.0-preview.2 version
const { createRequest } = require("#aws-sdk/util-create-request"); // 0.1.0-preview.2 version
const { formatUrl } = require("#aws-sdk/util-format-url"); // 0.1.0-preview.1 //version
const fetch = require("node-fetch");
(async () => {
try {
const region = "us-east-1";
const Bucket = `SOME_BUCKET_NAME`;
const Key = `SOME_KEY_VALUE`;
const credentials = {
accessKeyId: ACCESS_KEY_HERE,
secretAccessKey: SECRET_KEY_HERE,
sessionToken: SESSION_TOKEN_HERE
};
const S3Client = new S3({ region, credentials, signatureVersion: 'v4' });
console.log('1'); // for quick debugging
const signer = new S3RequestPresigner({ ...S3Client.config });
console.log('2')
const request = await createRequest(
S3Client,
new GetObjectCommand({ Key, Bucket })
);
console.log('3');
let signedUrl = formatUrl(await signer.presign(request));
console.log(signedUrl);
let response = await fetch(signedUrl);
console.log("Response", response);
}catch(e) {
console.error(e);
}
I successfully create S3Client and signer but on creating request, I get the following error:
clientStack.concat(...).filter is not a function
Anything wrong I am doing?
Please also note that I am using webpack for bundling

Answer 1

Just add my example in TypeScript:
import { S3Client, GetObjectCommand, S3ClientConfig } from '#aws-sdk/client-s3';
import { getSignedUrl } from '#aws-sdk/s3-request-presigner';
const s3Configuration: S3ClientConfig = {
credentials: {
accessKeyId: '<ACCESS_KEY_ID>',
secretAccessKey: '<SECRET_ACCESS_KEY>'
},
region: '<REGION>',
};
const s3 = new S3Client(s3Configuration);
const command = new GetObjectCommand({Bucket: '<BUCKET>', Key: '<KEY>' });
const url = await getSignedUrl(s3, command, { expiresIn: 15 * 60 }); // expires in seconds
console.log('Presigned URL: ', url);

RESOLVED
I ended up successfully making the signed urls by installing the beta versions rather than preview (default) ones
