A command line utility that compiles an ActionScript project configured with an asconfig.json file. This utility parses the configuration file and runs the compiler with the appropriate options. It can also package an Adobe AIR application. Supports a variety of ActionScript SDKs, including Adobe AIR SDK & Compiler, Apache Flex, the Feathers SDK, and Apache Royale.


Requires Node.js.

npm install -g asconfigc


Run asconfigc in a directory containing an asconfig.json file.

The following options are available:


    Compile a project with the path to its configuration file or a directory containing asconfig.json. If omitted, will look for asconfig.json in current working directory.

  • --sdk DIRECTORY

    Specify the directory where the ActionScript SDK is located. If omitted, defaults to checking FLEX_HOME and PATH environment variables for a supported SDK.

  • --debug=true or --debug=false

    Specify debug or release mode. Overrides the debug compiler option, if specified in asconfig.json.

  • --air PLATFORM

    Package the project as an Adobe AIR application. The allowed platforms include android, ios, windows, mac, and air.

  • -h or --help

    Print help message.

  • -v or --version

    Print the version of asconfigc.

Made with Apache Royale

The source code for the asconfigc utility is written in ActionScript. That's right, a utility that runs on Node.js — written in ActionScript and compiled with Apache Royale. Pretty cool, right?
