Overview of the ArkTS Compilation Toolchain
The ArkTS SDK provides a comprehensive toolchain for compiling ArkTS applications. Integrated with the Hvigor task orchestration tool, this toolchain compiles ArkTS/TS/JS source code into Ark bytecode files (*.abc).
During compilation, the toolchain first performs syntax transformation, including syntax checking and UI transformation. To ensure source code security, it uses ArkGuard for source code obfuscation. Before the bytecode is written to disk, the toolchain checks whether custom bytecode modifications are required. If modifications are required, custom modification code is loaded and executed. After generating the bytecode file, the Disassembler tool is used to inspect the file content. For details about the bytecode, see Ark Bytecode File Format.
The ArkTS compiler toolchain currently provides the following features:
-
Syntax check: checks whether the ArkTS/TS syntax is correct.
-
UI transformation: converts UI declarative paradigm syntax to standard TS syntax.
-
Source code obfuscation: uses the ArkGuard tool to obfuscate the source code. You can enable this feature based on service requirements.
-
Bytecode compilation: The Ark compiler generates Ark bytecode files (*.abc).
-
Custom bytecode modification: provides an entry for you to modify bytecode before it is written to disk.
-
Disassembly: uses the Disassembler tool to convert bytecode into human-readable assembly instructions.
The following figure shows how the ArkTS compilation toolchain builds a HAP.
