An example to create a presigned url with Node.js

presigned url (doppio.sh 👋).js

const { getSignedUrl } = require('@aws-sdk/s3-request-presigner');
const { S3Client, PutObjectCommand } = require('@aws-sdk/client-s3');

const connectedClient = new S3Client({
  credentials: {
    accessKeyId: process.env.S3_ACCESS_KEY_ID,
    secretAccessKey: process.env.S3_SECRET_ACCESS_KEY,
  },
  endpoint: `https://${process.env.S3_ENDPOINT}`,
  region: 'eu-east-1',
});

const command = new PutObjectCommand({
  Bucket: 'YOUR_BUCKET_NAME',
  Key: 'doppio/presignedtest' + Date.now() + '.pdf', //filename, 'doppio' will become a folder
  ContentType: 'application/pdf',
});

const url = getSignedUrl(connectedClient, command, { expiresIn: 3600 });

url.then(url => {
  console.log(url);
});
