From manual to automation, from repetition to innovation, the evolution of technology has been accompanied by development of developer tools. In this paper, from the author: Linux technology, the original address: https://www.jianshu.com/p/58ec32eef2d4
Alibaba opens its technology accumulation in various business scenarios to the outside world in the form of open source, cloud implementation or tools. This article will select some developer tools of Alibaba, hoping to help developers improve development efficiency and write code more gracefully.
Since developers are involved in so many technical fields, THE author only reviews the tools that are available from the perspective of a back-end developer in the area that I am familiar with. Each tool is described as follows:
-
Tool name and introduction
-
Usage scenarios
-

HandyJSON for iOS
HandyJSON is a JSON serialization/deserialization library for the Swift language.
Compared to other popular Swift JSON libraries, HandyJSON supports pure Swift classes and is easy to use. It does not require the Model to inherit from NSObject (since it is not KVC based), nor does it require you to define a Mapping function for the Model. As long as you define the Model class and declare that it follows the HandyJSON protocol, HandyJSON can parse values from JSON strings by itself, using the attribute name Key for each property.
