ArkCompiler JS Runtime

Introduction

ArkCompiler JS Runtime is the default JS runtime on OpenHarmony. It supports ECMAScript libraries and efficient container libraries. It also provides a set of native APIs for C++ and JS interaction and a variety of garbage collectors that features high performance.

For more information, see ArkCompiler JS Runtime.

Constraints

Only the ArkCompiler bytecode files generated by ts2abc, which is the ArkCompiler JS frontend toolchain, can be run.
Only the ES2021 standard and strict modes are supported.
Functions cannot be dynamically created using strings, such as new Function("console.log(1);")).

Building

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

Available APIs

See NAPI.

Usage

For details about how to generate JS bytecodes, see Using the Toolchain.

To run bytecodes:

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

For more information, see [ARK Runtime Usage Guide](https://gitee.com/openharmony/arkcompiler_ets_runtime/blob/master/ docs/ARK-Runtime-Usage-Guide.md).
