azure-storage-node-promisify

azure-storage is a wonderful and cheap way to store objects and blobs. Be sure to check it out here: [https://azure.microsoft.com/en-us/services/storage/]. However, the current version of the Azure Storage API for Node. The entire API uses callbacks. Node.js APIs suffered the same issue, leading ot callback hell. The solution is to promisify the callback functions so that it is compatible with await / async syntax. Since Node.js 8.x, a new promisify function has been introduced for the util module.

Installation

npm install azure-storage-node-promisify

Usage

This library is Typescript friendly. It tries to preserve the parameter as much as possible.

import azure from 'azure-storage';
import { promisifyTableService } from 'azure-storage-node-promisify';
 
const connectionString = '...'; // you can use any of the Azure Storage Node SDK's auth methods
const tableService = promisifyTableService(azure.createTableService(connectionString));
 
(async () => {
  await tableService.createTableIfNotExistsAsync('testTable');
 
  // Welcome to the future of CHEAP storage and async / await syntax!
})();
