AzCopy Azure Storage NodeJs

Question

I have a page developed in NodeJs and I want to pass a file.txt from my local to my storage account using azcopy-node.The code I currently have is as follows:

const { AzCopy } = require("@azure-tools/azcopy-node");

const azCopy = new AzCopy({
    accountName: "myaccount",
    accountKey: "mykey",
});

// Copy a local file to a storage account
azCopy.copy(__dirname + "/../../auto_load_event/1239.txt", "https://mystorage.blob.core.windows.net/container/1239.txt");

The problem I have is that when running it tells me that azcopy is not a constructor, and when I see the documentation of this link: https://www.npmjs.com/package/@azure-tools/azcopy-node I tried the code shown as an example and it does not work for me either, the error that shows me with this code is:

TypeError: Cannot read properties of undefined (reading 'fromTo')

I would like to be able to pass .TXT files from my local to my storage_account using Azcopy or if you know a better way to transfer files I thank you for sharing the information

If you know a better way to transfer files I thank you for sharing the information

You can try with @azure/storage-blob package to copy a file from local to Azure blob storage.

Code:

const { BlobServiceClient } = require("@azure/storage-blob");
const fs = require("fs");

async function uploadFileToBlobStorage() {
  const connectionString = "<your-storage connection string>";
  const containerName = "<container name>";
  const blobName = "sample.txt";
  const filePath = "C:\\Users\\v-xxx\\xxx\\xxx\\file.txt";

  const blobServiceClient = BlobServiceClient.fromConnectionString(connectionString);
  const containerClient = blobServiceClient.getContainerClient(containerName);
  const blockBlobClient = containerClient.getBlockBlobClient(blobName);

  const uploadOptions = {
    bufferSize: 4 * 1024 * 1024, 
    maxBuffers: 20
  };

  const stream = fs.createReadStream(filePath);
  const uploadResult = await blockBlobClient.uploadStream(stream, uploadOptions.bufferSize, uploadOptions.maxBuffers);

  console.log("Upload successful");
}

uploadFileToBlobStorage();

Output:
