方舟编译器JS运行时组件

简介

方舟编译器JS运行时(ArkCompiler JavaScript Runtime)是OpenHarmony上默认的JavaScript语言运行时。支持Ecmascript规范定义的标准库和高效container容器库,提供完备的C++交互JSNAPI和各种高性能的垃圾回收器,驱动着万物互联时代的OpenHarmony应用程序。

约束

  • 仅支持运行方舟JS前端工具链(ts2abc)生成的方舟字节码文件
  • 只支持ES2015标准和严格模式(use strict)
  • 不支持通过字符串动态创建函数(比如new Function("console.log(1);"))

编译构建

$./build.sh --product-name hispark_taurus_standard --build-target ark_js_host_linux_tools_packages

接口说明

NAPI接口说明参考NAPI组件

使用说明

JS生成字节码参考工具链使用

字节码执行:

LD_LIBRARY_PATH=out/hispark_taurus/clang_x64/ark/ark:out/hispark_taurus/clang_x64/ark/ark_js_runtime:out/hispark_taurus/clang_x64/thirdparty/icu:prebuilts/clang/ohos/linux-x86_64/llvm/lib ./out/hispark_taurus/clang_x64/ark/ark_js_runtime/ark_js_vm helloworld.abc
