ARK JS Runtime Module
Introduction
ARK JS Runtime is the runtime used by JavaScript JS
applications on OpenHarmony. It consists of the JS object allocator, garbage collector GC
, a standard library compliant with ECMAScript specifications, ARK bytecode interpreter, inline caches that store hidden classes, and the ARK Foreign Function Interface AFFI
.
For more information, see: ARK Runtime Subsystem.

Constraints
- Only the bytecode file generated by the ARK JS frontend can be run.
- Only support ES2015 standard and strict mode ("use strict").
- Don't support dynamically create functions via string (e.g., new Function("console.log(1))).
Build
./build.sh --product-name rk3568 --build-target ark_js_host_linux_tools_packages
Available APIs
For details, see NAPI.
Usage Guidelines
For details about how to generate JS bytecodes, see Using the Toolchain.
To run bytecodes:
LD_LIBRARY_PATH=out/rk3568/clang_x64/ark/ark:out/rk3568/clang_x64/ark/ark_js_runtime:out/rk3568/clang_x64/thirdparty/icu:prebuilts/clang/ohos/linux-x86_64/llvm/lib ./out/rk3568/clang_x64/ark/ark_js_runtime/ark_js_vm helloworld.abc
