The ARK front-end tools use the command line interaction mode and convert JS code into ARK bytecodes that can run on ARK runtime. The toolchain supports Windows, Linux, and macOS.
JS Bytecode Compiler
Front-end tools, converting JS source code into ARK bytecode, can be built by specifying the --build-target with ark_ts2abc.
Build tools:
$ $ ./build.sh --product-name rk3568 --build-target ets_frontend_build
$ cd out/rk3568/clang_x64/arkcompiler/ets_frontend/
$ ./es2abc [options] file.js
If no parameter is specified for [options], an ARK binary file is generated by default.
