Microsoft Azure Storage Client Library for Node.js and JavaScript

Class: BlobService

BlobService

The BlobService class is used to perform operations on the Microsoft Azure Blob Service.
The Blob Service provides storage for binary large objects, and provides
functions for working with data stored in blobs as either streams or pages of data.

For more information on the Blob Service, as well as task focused information on using it in a Node.js application, see
How to Use the Blob Service from Node.js.
The following defaults can be set on the blob service.
singleBlobPutThresholdInBytes The default maximum size, in bytes, of a blob before it must be separated into blocks.
defaultEnableReuseSocket The default boolean value to enable socket reuse when uploading local files or streams.
If the Node.js version is lower than 0.10.x, socket reuse will always be turned off.
defaultTimeoutIntervalInMs The default timeout interval, in milliseconds, to use for request made via the Blob service.
defaultClientRequestTimeoutInMs The default timeout of client requests, in milliseconds, to use for the request made via the Blob service.
defaultMaximumExecutionTimeInMs The default maximum execution time across all potential retries, for requests made via the Blob service.
defaultLocationMode The default location mode for requests made via the Blob service.
parallelOperationThreadCount The number of parallel operations that may be performed when uploading a blob that is greater than
the value specified by the singleBlobPutThresholdInBytes property in size.
useNagleAlgorithm Determines whether the Nagle algorithm is used for requests made via the Blob service; true to use the
Nagle algorithm; otherwise, false. The default value is false.
enableGlobalHttpAgent Determines whether global HTTP(s) agent is enabled; true to use Global HTTP(s) agent; otherwise, false to use
http(s).Agent({keepAlive:true}).

new BlobService( [storageAccountOrConnectionString] [, storageAccessKey] [, host] [, sas] [, endpointSuffix] [, token])

Creates a new BlobService object.
If no connection string or storageaccount and storageaccesskey are provided,

var blobService = azure.createBlobService();
blobService.createBlockFromText("sampleBlockName", containerName, blobName, "sampleBlockContent", function(error) {
  assert.equal(error, null);
  // In this example, LatestBlocks is used, we hope the Blob service first search
  // the uncommitted block list, and then the committed block list for the named block "sampleBlockName",
  // and thus make sure the block is with latest content.
  blobService.commitBlocks(containerName, blobName, { LatestBlocks: ["sampleBlockName"] }, function(error) {

createAppendBlobFromBrowserFile(container, blob, browserFile [, options], callback)

Creates a new append blob from an HTML File object. If the blob already exists on the service, it will be overwritten.
To avoid overwriting and instead throw an error if the blob exists, please pass in an accessConditions parameter in the options object.
This API should be used strictly in a single writer scenario because the API internally uses the append-offset conditional header to avoid duplicate blocks.
If you are guaranteed to have a single writer scenario, please look at options.absorbConditionalErrorsOnRetry and see if setting this flag to true is acceptable for you.
If you want to append data to an already existing blob, please look at appendFromBrowserFile.

If you are guaranteed to have a single writer scenario, please look at options.absorbConditionalErrorsOnRetry and see if setting this flag to true is acceptable for you.

withFilter(filter)

Associate a filtering operation with this StorageServiceClient. Filtering operations
can include logging, automatically retrying, etc. Filter operations are objects
that implement a method with the signature:

"function handle (requestOptions, next)".

After doing its preprocessing on the request options, the method needs to call
"next" passing a callback with the following signature:
signature:

"function (returnObject, finalCallback, next)"

In this callback, and after processing the returnObject (the response from the
request to the server), the callback needs to either invoke next if it exists to
continue processing other filters or simply invoke finalCallback otherwise to end
up the service invocation.

Parameters:
Name Type Description
filter Object

The new filter object.
Inherited From:
Source:
Returns:

A new service client with the filter applied.
