re-frame est un framework fonctionnel pour construire des applications monopages (SPA) en ClojureScript. Il fournit une base de données centralisée et immuable qui sert de source unique de vérité pour l'état global de l'application, imposant un flux de données unidirectionnel strict où les événements déclenchent des transitions d'état et des mises à jour de vue. Le framework se distingue par un graphe de signaux réactifs et un pipeline de middleware basé sur des intercepteurs. En traitant la logique applicative comme une séquence d'événements pilotés par les données et d'effets de bord déclaratifs, il découple la logique métier de la couche de vue. Cette architecture permet aux développeurs de gérer des transitions d'état complexes et des opérations externes via des fonctions pures, garantissant que les effets de bord sont exécutés par un interpréteur séparé plutôt que par des appels impératifs. Le système inclut une suite complète de capacités pour gérer l'architecture applicative, notamment la dérivation de données réactives, la réconciliation de vue basée sur les abonnements et la gestion d'état pilotée par les événements. Il prend en charge des flux de développement avancés tels que le traçage d'événements, la mise en point d'état et la possibilité de simuler (stub) des effets de bord pour des tests isolés. Le projet est conçu pour une intégration avec React, utilisant la réconciliation du DOM virtuel pour mettre à jour efficacement les interfaces utilisateur. Il fournit un ensemble robuste d'utilitaires pour gérer les préoccupations transversales, les graphes de flux de données complexes et coordonner les opérations asynchrones au sein d'un pipeline d'événements séquentiel et prévisible.
