Why
DFX use test in the use of hap, found that generate json file could not be chrome parsing

Description
Change the time stamp of the type of the variable, which can be stored subtle level
Change the code logic, which can identify fault frames and export right to json

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 infomation, 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 Hi3516DV300 --build-target ark_js_runtime

Available APIs

For details, see NAPI.

Usage Guidelines

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

To run bytecodes:

$ cd out/release
$ export LD_LIBRARY_PATH=clang_x64/ark/ark_js_runtime:clang_x64/ark/ark:clang_x64/global/i18n:../../prebuilts/clang/ohos/linux-x86_64/llvm/lib/
$ ./clang_x64/ark/ark_js_runtime/ark_js_vm helloworld.abc
