Timing

Green Flag Request

The greenflag serves as a prompt dispatched precisely during post application launch. It functions as an app instigator, managing the initial execution of the application. On a more pragmatic level, greenflag is simply a function, dedicated to run the script content of the application during app launch. The greenflag request delineates the procedural pathway through this function, which, in turn, is invoked by the App launcher directly into the application WebView. (Every app has their own unique greenflag broadcast, they will not interfere.)

But, from NovaOS 1.5, the greenflag function is not required for an application, and orphaned scripts will get executed in order.

Sample code:

function greenflag() {
  initialiseUI();
}
