Detailinformationen

The jEAP Server-Sent Events (SSE) library enables real-time, server-to-client event streaming over HTTP using the SSE standard. It provides a configurable web endpoint where UI clients can subscribe to receive events such as resource creation, updates, deletions, and periodic heartbeat signals. Multiple backend instances are synchronized via Kafka to ensure all connected clients receive all relevant events, regardless of which instance initiated the change. The library offers flexible authentication options, including insecure, simple role-based, and semantic resource/operation-based access control. It exposes a simple business logic API (ResourceMutationService) for publishing events and handles dispatch to all listeners automatically. With configurable heartbeat rates, emitter timeouts, and Kafka topics, it supports scalable, efficient, and secure integration of real-time updates into jEAP-based microservices and UI applications.
