Background In the Kai hong operating system (Kaihong Operating System, kaihongOS), a layered architecture is typically employed in which the application layer is developed using a high-level language such as JavaScript (JS) or TYPESCRIPT (type script, TS), where TYPESCRIPT may be a ark type script (ARK TYPESCRIPT, ARKTS). The system framework layer uses a native language such as C (C programming language) or C++ (C++ programming language, C++ Programming Languages) to implement core functions. The local application program interface (NATIVE API, NAPI) serves as an important bridge mechanism, so that JavaScript code of the application layer can safely and efficiently call a C or C++ interface of the system layer. Currently, writing the corresponding NAPI function for each C or c++ interface that needs to be exposed to the application layer is a highly human-dependent process. The developer must deeply understand the complex programming specification of the NAPI, and manually complete the tedious and error-prone steps of type conversion, asynchronous callback processing, memory management, and the like. This development mode has the following significant drawbacks: 1. the efficiency is low, when the system framework needs to open a large number of interfaces to the application layer, manually writing NAPI functions becomes a development bottleneck, and seriously slow the project progress. 2. The skill threshold is high, the developer is required to be proficient in both high-level language and native language, and the NAPI programming skills are mastered skillfully, so that the labor cost is increased. 3. The code quality is uneven, the coding habit and style of different developers are different, the generated NAPI codes are not uniform in style, the readability and maintainability are poor, and potential errors are easy to introduce.
