When you set permissions for a container, the existing permissions are replaced. If no access or containerAcl provided, the existing container ACL will be removed.

When you establish a stored access policy on a container, it may take up to 30 seconds to take effect. During this interval, a shared access signature that is associated with the stored access policy will fail with status code 403 (Forbidden), until the access policy becomes active.

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

setMetadata(Metadata, ContainerSetMetadataOptions)

Sets one or more user-defined name-value pairs for the specified container.

uploadBlockBlob(string, RequestBodyType, number, BlockBlobUploadOptions)

Creates a new block blob, or updates the content of an existing block blob.

Updating an existing block blob overwrites any existing metadata on the blob. Partial updates are not supported; the content of the existing blob is overwritten with the new content. To perform a partial update of a block blob's, use stageBlock and commitBlockList.

This is a non-parallel uploading method, please use uploadFile, uploadStream or uploadBrowserData for better performance with concurrency uploading.

let i = 1;
for await (const response of containerClient
  .listBlobsByHierarchy("/", { prefix: "prefix2/sub1/" })
  .byPage({ maxPageSize: 2 })) {
  console.log(`Page ${i++}`);
  const segment = response.segment;

  if (segment.blobPrefixes) {
    for (const prefix of segment.blobPrefixes) {
      console.log(`\tBlobPrefix: ${prefix.name}`);
    }
  }

  for (const blob of response.segment.blobItems) {
    console.log(`\tBlobItem: name - ${blob.name}`);
  }
}
function listBlobsByHierarchy(delimiter: string, options?: ContainerListBlobsOptions): PagedAsyncIterableIterator<({ kind: "prefix" } & BlobPrefix) | ({ kind: "blob" } & BlobItem), ContainerListBlobHierarchySegmentResponse, PageSettings>

Parameters

delimiter

string

The character or string used to define the virtual hierarchy

options
ContainerListBlobsOptions

Options to list blobs operation.

Returns

listBlobsFlat(ContainerListBlobsOptions)

Returns an async iterable iterator to list all the blobs under the specified account.

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

Example using for await syntax:

// Get the containerClient before you run these snippets,
// Can be obtained from `blobServiceClient.getContainerClient("<your-container-name>");`
let i = 1;
for await (const blob of containerClient.listBlobsFlat()) {
  console.log(`Blob ${i++}: ${blob.name}`);
}

Example using iter.next():

let i = 1;
let iter = containerClient.listBlobsFlat();
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 containerClient.listBlobsFlat().byPage({ maxPageSize: 20 })) {
  for (const blob of response.segment.blobItems) {
    console.log(`Blob ${i++}: ${blob.name}`);
  }
}

Example using paging with a marker:

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

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

// Gets next marker
let marker = response.continuationToken;

// Passing next marker as continuationToken

iterator = containerClient.listBlobsFlat().byPage({ continuationToken: marker, maxPageSize: 10 });
response = (await iterator.next()).value;

// Prints 10 blob names
for (const blob of response.segment.blobItems) {
  console.log(`Blob ${i++}: ${blob.name}`);
}
function listBlobsFlat(options?: ContainerListBlobsOptions): PagedAsyncIterableIterator<BlobItem, ContainerListBlobFlatSegmentResponse, PageSettings>

Parameters

options
ContainerListBlobsOptions

Options to list blobs.

Returns

An asyncIterableIterator that supports paging.

setAccessPolicy(PublicAccessType, SignedIdentifier[], ContainerSetAccessPolicyOptions)

Sets the permissions for the specified container. The permissions indicate whether blobs in a container may be accessed publicly.

When you set permissions for a container, the existing permissions are replaced. If no access or containerAcl provided, the existing container ACL will be removed.

When you establish a stored access policy on a container, it may take up to 30 seconds to take effect. During this interval, a shared access signature that is associated with the stored access policy will fail with status code 403 (Forbidden), until the access policy becomes active.

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

function setAccessPolicy(access?: PublicAccessType, containerAcl?: SignedIdentifier[], options?: ContainerSetAccessPolicyOptions): Promise<ContainerSetAccessPolicyResponse>

Parameters

access
PublicAccessType

The level of public access to data in the container.

containerAcl

SignedIdentifier[]

Array of elements each having a unique Id and details of the access policy.

options
ContainerSetAccessPolicyOptions

Options to Container Set Access Policy operation.

Returns

setMetadata(Metadata, ContainerSetMetadataOptions)

Sets one or more user-defined name-value pairs for the specified container.

If no option provided, or no metadata defined in the parameter, the container metadata will be removed.

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

function setMetadata(metadata?: Metadata, options?: ContainerSetMetadataOptions): Promise<ContainerSetMetadataResponse>

Parameters

metadata
Metadata

Replace existing metadata with this value. If no value provided the existing metadata will be removed.

options
ContainerSetMetadataOptions

Options to Container Set Metadata operation.

Returns

uploadBlockBlob(string, RequestBodyType, number, BlockBlobUploadOptions)

Creates a new block blob, or updates the content of an existing block blob.

Updating an existing block blob overwrites any existing metadata on the blob. Partial updates are not supported; the content of the existing blob is overwritten with the new content. To perform a partial update of a block blob's, use stageBlock and commitBlockList.

This is a non-parallel uploading method, please use uploadFile, uploadStream or uploadBrowserData for better performance with concurrency uploading.

See https://docs.microsoft.com/rest/api/storageservices/put-blob

function uploadBlockBlob(blobName: string, body: RequestBodyType, contentLength: number, options?: BlockBlobUploadOptions): Promise<{ blockBlobClient: BlockBlobClient, response: BlockBlobUploadResponse }>

Parameters

blobName

string

Name of the block blob to create or update.

body
HttpRequestBody

Blob, string, ArrayBuffer, ArrayBufferView or a function which returns a new Readable stream whose offset is from data source beginning.

contentLength

number

Length of body in bytes. Use Buffer.byteLength() to calculate body length for a string including non non-Base64/Hex-encoded characters.

options
BlockBlobUploadOptions

Options to configure the Block Blob Upload operation.

Returns

Promise<{ blockBlobClient: BlockBlobClient, response: BlockBlobUploadResponse }>

Block Blob upload response data and the corresponding BlockBlobClient instance.
