  • Download and install Visual Studio Code

  • Install Josh Tynjala's asconfigc, a command line utility for compiling AS/MXML projects (as of version 0.9.0 this step is optional as asconfigc is now included in the extension.)

  • Install the AS/MXML VSCode Extension by the same author. (Searching within VS Code is the easiest way to do this.)

  • Select a workspace in VSCode

  • Select SDK for workspace

  • Set up project: (Note: Yeoman can be used to automate this step.) The linked project is no longer active and was created for FlexJS. It should be easy to make it compatible with Royale.

    + -- asconfig.json
    • in 'asconfig.json':

    • in 'src/HelloRoyale.mxml'

      <?xml version="1.0" encoding="utf-8"?>

      			<js:Label text="Hello World" x="100" y="100"/>
  • Select Tasks > Run Build Task... to build (or equivalent shortcut).

  • Open bin/js-debug/index.html or bin/js-release/index.html in your browser and you should see "Hello World".

For instructions on more integrated debugging, please refer to the extension documentation for Chrome, Firefox or Node JS.
