angular-loading-bar ist ein Ladestatus-Manager und Fortschrittsbalken-Komponente für Angular-Anwendungen. Sie bietet ein System zur Visualisierung der Netzwerk-Request-Aktivität durch einen automatischen Ladeindikator, der ausgehende HTTP-Requests überwacht. Das Projekt verwaltet gleichzeitige Netzwerk-Requests durch Bündelung mehrerer API-Aufrufe in einen einzigen Ladestatus, wodurch sichergestellt wird, dass der Indikator sichtbar bleibt, bis der letzte Request abgeschlossen ist. Es enthält einen Latenz-Schwellenwert, um das Erscheinen des Ladebalkens zu verzögern, was visuelles Flackern bei schnellen Requests verhindert. Das System unterstützt URL-Musterfilterung, um spezifische Hintergrund- oder Polling-Aufrufe vom Auslösen des UI auszuschließen. Es bietet zudem manuelle Statuskontrolle, die es ermöglicht, den Ladeindikator programmgesteuert für Aufgaben unabhängig vom Netzwerk-Monitoring zu starten oder zu stoppen.
