Upload

Upload allows for easy and efficient uploading of buffers, blobs, or streams, using a configurable amount of concurrency to perform multipart uploads where possible. This abstraction enables uploading large files or streams of unknown size due to the use of multipart uploads under the hood.

import { Upload } from "@aws-sdk/lib-storage";
import { S3Client, S3 } from "@aws-sdk/client-s3";

try {
  const parallelUploads3 = new Upload({
    client: new S3({}) || new S3Client({}),
    params: { Bucket, Key, Body },

    // optional tags
    tags: [
      /*...*/
    ],

    // additional optional fields show default values below:

    // (optional) concurrency configuration
    queueSize: 4,

    // (optional) size of each part, in bytes, at least 5MB
    partSize: 1024 * 1024 * 5,

    // (optional) when true, do not automatically call AbortMultipartUpload when
    // a multipart upload fails to complete. You should then manually handle
    // the leftover parts.
    leavePartsOnError: false,
  });

  parallelUploads3.on("httpUploadProgress", (progress) => {
    console.log(progress);
  });

  await parallelUploads3.done();
} catch (e) {
  console.log(e);
}
