re-frame ist ein funktionales Framework für den Bau von Single-Page-Anwendungen in ClojureScript. Es bietet eine zentralisierte, unveränderliche Datenbank, die als Single Source of Truth für den gesamten Anwendungszustand dient und einen strikten, unidirektionalen Datenfluss erzwingt, bei dem Events Zustandsübergänge und nachfolgende View-Updates auslösen. Das Framework zeichnet sich durch einen reaktiven Signal-Graphen und eine Interceptor-basierte Middleware-Pipeline aus. Indem Anwendungslogik als Sequenz datengetriebener Events und deklarativer Side-Effects behandelt wird, entkoppelt es die Geschäftslogik von der View-Schicht.
