routes

Source:

Here path is routeID, navigatorID is viewNavigatorId, parentId is DOM Element Id or ViewId in case of Nested View Navigators By Default Main DOM Element have id="root"

Example
Sample Router Object is to be implement in "AppViewManager" class (subclass of ViewManager) 
     
        initRoutes() {
            let tmpRoutes = [
                { path: "/login", navigatorId: " LoginNavigator",parentId: "root" },
                { path: "/file", navigatorId: " FileNavigator",parentId: "root" },
                { path: "/logout", navigatorId: "ExitNavigator",parentId: "root" },
            ]
            this.routes = new Router(tmpRoutes);
        }

      Here "path" is routeID, "navigatorId" is viewNavigatorId, "parentId" is DOM Element Id or ViewId or ContainerId.
      By Default Main DOM Element have id="root"
