DataLakeServiceClient

Retrieves a user delegation key for the Data Lake service. This is only a valid operation when using bearer token authentication.

example

// Generate user delegation SAS for a file system
const userDelegationKey = await dataLakeServiceClient.getUserDelegationKey(startsOn, expiresOn);
const fileSystemSAS = generateDataLakeSASQueryParameters({
    fileSystemName, // Required
    permissions: FileSystemSASPermissions.parse("racwdl"), // Required
    startsOn, // Required. Date type
    expiresOn, // Optional. Date type
    ipRange: { start: "0.0.0.0", end: "255.255.255.255" }, // Optional
    protocol: SASProtocol.HttpsAndHttp, // Optional
    version: "2018-11-09" // Must >= 2018-11-09 to generate user delegation SAS
  },
  userDelegationKey, // UserDelegationKey
  accountName
).toString();

DataLakeServiceClient

.byPage() returns an async iterable iterator to list the file systems in pages.

Example using for await syntax:

let i = 1;
for await (const fileSystem of serviceClient.listFileSystems()) {
  console.log(`FileSystem ${i++}: ${fileSystem.name}`);
}

Example using iter.next():

let i = 1;
const iter = serviceClient.listFileSystems();
let fileSystemItem = await iter.next();
while (!fileSystemItem.done) {
  console.log(`FileSystem ${i++}: ${fileSystemItem.value.name}`);
  fileSystemItem = await iter.next();
}

Example using byPage():

// passing optional maxPageSize in the page settings
let i = 1;
for await (const response of serviceClient.listFileSystems().byPage({ maxPageSize: 20 })) {
  if (response.fileSystemItems) {
    for (const fileSystem of response.fileSystemItems) {
      console.log(`FileSystem ${i++}: ${fileSystem.name}`);
    }
  }
}

Example using paging with a marker:

let i = 1;
let iterator = serviceClient.listFileSystems().byPage({ maxPageSize: 2 });
let response = (await iterator.next()).value;

// Prints 2 file system names
if (response.fileSystemItems) {
  for (const fileSystem of response.fileSystemItems) {
    console.log(`FileSystem ${i++}: ${fileSystem.name}`);
  }
}

// Gets next marker
let marker = response.continuationToken;
// Passing next marker as continuationToken
iterator = serviceClient
  .listContainers()
  .byPage({ continuationToken: marker, maxPageSize: 10 });
response = (await iterator.next()).value;

// Prints 10 file system names
if (response.fileSystemItems) {
  for (const fileSystem of response.fileSystemItems) {
     console.log(`FileSystem ${i++}: ${fileSystem.name}`);
  }
}
