Therefore, while the VS Code debugger is attached, every change to the app's source will trigger a livesync (after saving the altered file) which will update and restart the target application while the VS Code debugger is automatically reattached to the new app instance preserving all breakpoints and watched expressions. What's more awesome is that the default launch configurations take advantage of the NativeScript CLI functionality. You can find more information about the debugging support in Visual Studio Code in the VS Code Debugging Guide. Once the debugger is attached you can inspect scope variables, set breakpoints, watch expressions, execute code while the app is paused on a breakpoint etc. If you want the execution to stop on the first JavaScript/TypeScript statement, functionality set the stopOnEntry flag to true in your launch.json configuration. This will trigger a NativeScript CLI command which will build, deploy and run your app in an iOS device or emulator and attach the Visual Studio Code debugger.
