Panel
Panel ist ein Python-Framework für Datenanwendungen, das zum Aufbau interaktiver Dashboards und reaktiver Benutzeroberflächen durch die Verbindung von Datenvisualisierungen, Widgets und Callbacks verwendet wird. Es fungiert als reaktive UI-Bibliothek, die den Anwendungszustand mit Interface-Updates basierend auf Benutzerinteraktionen synchronisiert.
Das Projekt zeichnet sich dadurch aus, dass es mehrere Ausführungsmodelle anbietet, darunter einen FastAPI-basierten Webanwendungsserver für skalierbares Session-Management und einen WebAssembly-Compiler, der es Python-Anwendungen ermöglicht, direkt im Browser ohne Backend-Server zu laufen. Es enthält zudem ein spezialisiertes Toolkit für den Aufbau konversationeller KI-Interfaces mit Streaming-Textantworten und Nachrichtenverläufen.
Das Framework deckt breite Funktionsbereiche ab, einschließlich responsivem Layout-Design, der Integration diverser Plotting-Bibliotheken und interaktiver Datentabellen sowie dem Management reaktiver Parameter. Es bietet Werkzeuge für Benutzerauthentifizierung, Session-Persistenz und die Planung von Hintergrundaufgaben.
