Create a Blob container.

See https://docs.microsoft.com/en-us/rest/api/storageservices/create-container

function createContainer(containerName: string, options?: ContainerCreateOptions): Promise<{ containerClient: ContainerClient, containerCreateResponse: ContainerCreateResponse }>

Parameters

Returns

Container creation response and the corresponding container client.

Deletes a Blob container.

function deleteContainer(containerName: string, options?: ContainerDeleteMethodOptions): Promise<ContainerDeleteResponse>

Parameters

Returns

Container deletion response.

Returns an async iterable iterator to find all blobs with specified tag under the specified account.

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

See https://docs.microsoft.com/en-us/rest/api/storageservices/get-blob-service-properties

Example using for await syntax:

let i = 1;
for await (const blob of blobServiceClient.findBlobsByTags("tagkey='tagvalue'")) {
  console.log(`Blob ${i++}: ${container.name}`);
}

Example using iter.next():

let i = 1;
const iter = blobServiceClient.findBlobsByTags("tagkey='tagvalue'");
let blobItem = await iter.next();
while (!blobItem.done) {
  console.log(`Blob ${i++}: ${blobItem.value.name}`);
  blobItem = await iter.next();
}

Example using byPage():

// passing optional maxPageSize in the page settings
let i = 1;
for await (const response of blobServiceClient.findBlobsByTags("tagkey='tagvalue'").byPage({ maxPageSize: 20 })) {
  if (response.blobs) {
    for (const blob of response.blobs) {
      console.log(`Blob ${i++}: ${blob.name}`);
    }
  }
}

Example using paging with a marker:

let i = 1;
let iterator = blobServiceClient.findBlobsByTags("tagkey='tagvalue'").byPage({ maxPageSize: 2 });
let response = (await iterator.next()).value;

// Prints 2 blob names
if (response.blobs) {
  for (const blob of response.blobs) {
    console.log(`Blob ${i++}: ${blob.name}`);
  }
}

// Gets next marker
let marker = response.continuationToken;
// Passing next marker as continuationToken
iterator = blobServiceClient
  .findBlobsByTags("tagkey='tagvalue'")
  .byPage({ continuationToken: marker, maxPageSize: 10 });
response = (await iterator.next()).value;

// Prints blob names
if (response.blobs) {
  for (const blob of response.blobs) {
     console.log(`Blob ${i++}: ${blob.name}`);
  }
}
