DOMAIN MODULE ROUTING MODULE CORE MODULE Import unique dans app.module Mettre tout les .forRoot() des modules tierce SHARED MODULE Import dans tout les features modules Composants et module partagés par les features modules FEATURE MODULE Généralement attaché directement au app.module ou indépendant par lazy-loading Gère toute une partie de l’application : interface + échange de donnée. ex : les commandes de produits Commun à quelques features modules Module en charge d’une fonctionnalité particulière qui regroupe plusieurs components, services… Module chargé de la déclaration des routes Attaché à un feature module, optionnel, le forRoot doit être dans le CoreModule
- 9. COMPONENT CONTAINER Composant chargé de récupérer et diffuser la donnée dans les autres sous-composants En relation avec le state-management ou les services, pas d’input/output Composant pouvant être utiliser dans plusieurs application différentes Ils ne demandent jamais la donnée directement, ils ont des input et output pour les événements à envoyer au composant parent
