npm install @azure/ms-rest-nodeauth
Sample code
import * as msRest from "@azure/ms-rest-js";
import * as msRestAzure from "@azure/ms-rest-azure-js";
import * as msRestNodeAuth from "@azure/ms-rest-nodeauth";
import { DataLakeStorageClient, DataLakeStorageModels, DataLakeStorageMappers } from "@azure/storage-datalake";
const subscriptionId = process.env["AZURE_SUBSCRIPTION_ID"];

msRestNodeAuth.interactiveLogin().then((creds) => {
  const client = new DataLakeStorageClient(creds, subscriptionId);
  const prefix = "testprefix";
  const continuation = "testcontinuation";
  const maxResults = 1;
  const xMsClientRequestId = "testxMsClientRequestId";
  const timeout = 1;
  const xMsDate = "testxMsDate";
  client.filesystem.list(prefix, continuation, maxResults, xMsClientRequestId, timeout, xMsDate).then((result) => {
    console.log("The result is:");
    console.log(result);
  });
}).catch((err) => {
  console.error(err);
});
