Get started with Alibaba Cloud Darabonba SDK for Node.js

Last Updated: May 31, 2022

Introduction

Darabonba SDK for Node.js is supported in Node.js 8.x and later versions. Multiple issues related to the Classic SDK are resolved in the Darabonba SDK. The Darabonba SDK introduces various new features. The Darabonba SDK is easy to understand, lowers the usage barriers, and improves the robustness of the SDK. This user guide describes the new features in detail. This user guide also describes how to use the Darabonba SDK by comparing the differences between the Classic and Darabonba SDKs.

New features

Darabonba SDK for Node.js is developed based on Darabonba. Darabonba is a domain-specific language (DSL) that is developed by Alibaba Cloud. You can use DSL to compile code in a flexible manner. You can also parse the DSL-generated abstract syntax trees (ASTs) to generate an SDK that is suitable for all types of API operations of different Alibaba Cloud services. For more information about Darabonba, visit Darabonba. Multiple issues related to the Classic SDK are resolved in the DSL-based Darabonba SDK. The DSL-based Darabonba SDK provides the following features:

  1. In the Classic SDK, the APIs of different Alibaba Cloud services vary based on the style, such as remote procedure call (RPC) and resource-oriented architecture (ROA). Therefore, the API operations of the services are called by using different methods. This issue is resolved in the Darabonba SDK, and the API operations of all Alibaba Cloud services can be called by using the same method.

  2. The DSL-based Darabonba SDK contains complete business logic. This resolves the issue that Classic SDK for Node.js supports only CommonRequest. Darabonba SDK for Node.js supports TypeScript. This way, you can compile code by using an integrated development environment (IDE) in an efficient manner.

  3. The Darabonba SDK is suitable for more complex scenarios. For example, to use Visual Intelligence API (VIAPI) to process an image, you must upload the image to Object Storage Service (OSS), and OSS generates a URL for the image. Then, you can specify the URL in VIAPI, and VIAPI analyzes and processes the image based on artificial intelligence (AI)-based technologies. If you use the Darabonba SDK, the identity authentication, image upload, and image processing can be complete in a simplified manner.

  4. Darabonba SDK for Node.js provides sample code for all API requests. Darabonba SDK for Node.js also provides usage scenarios in which multiple API requests are sent. This way, when you use Darabonba SDK for Node.js, you incur low development costs and you can focus more on your business scenario.
