From manual coding to automation and from repeated work to innovation, developer tools have been evolving along with technologies. Alibaba Group and Alibaba Cloud have made its technologies available to public through open source release and cloud-based implementation. These technologies have been accumulated through years of development in various business scenarios. This article introduces some Alibaba developer tools in the hopes that they can help make your development process more efficient and graceful.
Given the vast diversity of technological branches that developers may engage in, this article introduces some tools that may be helpful for backend developers.
Arthas is an online diagnostic tool for Java applications open-sourced by Alibaba in September 2018.
Arthas supports Java Development Kit (JDK) 6 and later versions, and it supports Linux, Mac, and Windows. Arthas uses the command line interaction mode, and allows you to use Tab to autocomplete commands in the command line, making problem locating and diagnosis much easier.

Cloud Toolkit is an integrated development environment (IDE) plug-in that can be used to help developers more efficiently develop, test, diagnose, and deploy applications. Cloud Toolkit allows developers to conveniently deploy local applications to any machines (on-premises or cloud-based). Cloud Toolkit is built-in with the Arthas diagnostic tool, and supports efficiently executing terminal commands and SQL statements. Cloud Toolkit is available for different IDEs such as IntelliJ IDEA, Eclipse, PyCharm, and Maven.
ChaosBlade is a chaos engineering tool that follows principles of chaos engineering experiments, and provides extensive fault scenarios to help you improve the fault tolerance and recoverability of distributed systems. It can inject underlying faults, and provides various fault scenarios. These scenarios include delays, exceptions, returning specific values, modification of parameter values, repeated calls, and try-catch block exceptions.

EasyExcel is a framework that parses Java code and generates excel files. It rewrites the Apache POI SAX parser for Microsoft Excel 2007. To process a 3 MB Excel file, the Apache POI SAX parser needs about 100 MB memory, while EasyExcel needs about several KB. In addition, EasyExcel eliminates the out-of-memory (OOM) problem, no matter how large the excel file is. For Microsoft Excel 2003, EasyExcel still uses the Apache POI SAX parser. But it encapsulates the model converter at the upper layer to make it easier to use.

HandyJSON is a json-object serialization/deserialization library written in Swift language.
Compared with other popular Swift JSON libraries, HandyJSON supports pure Swift classes and is easy to use. When you use HandyJSON in deserialization, which converts JSON to model, the model does not have to inherit from the NSObject, because HandyJSON is not KVC-based. You do not have to define a mapping function for the model either. After you define the model class and declare that it follows the HandyJSON protocol, HandyJSON automatically parses values from JSON strings by taking the property name as the key.
