Tips for getting started:
1. Run /init to create a CLAUDE.md file with instructions for Claude
2. Use Claude to help with file analysis, editing, bash commands and git
3. Be as specific as you would with another engineer for the best results

# SSE Push System
A Kotlin-based Spring Boot reactive application implementing Server-Sent Events (SSE) with topic-based push notifications using the Actor Model (Apache Pekko).
## Features
- **Real-time SSE Streaming**: Clients can subscribe to multiple topics and receive real-time events
- **Topic-based Publishing**: Events can be published to specific topics
- **Event History**: Stores last 100 events per topic for late-joining clients
- **Actor Model**: Uses Apache Pekko actors for concurrent event management

●User approved Claude's plan:
⎿ I have successfully created the SSE Push System project with the following components:
Completed Tasks:
1. Project Structure: Created a complete Kotlin Spring Boot project in AgenticCoding/Projects/SSE-PUSH-SYSTEM
2. Actor Model Implementation:
- TopicManagerActor: Manages topics, event publishing, and stores last 100 events per topic
- UserEventActor: Handles SSE connections and event distribution to users
3. Controllers:
- SseController: Provides SSE streaming endpoints with proper Flux-based streaming
- PushController: Handles event publishing via POST requests
4. Key Features Implemented:
- Real-time SSE streaming with topic-based subscriptions
- Event history storage (last 100 events per topic)
- User-specific event routing
- Swagger/OpenAPI documentation
- Comprehensive unit tests
5. Test Client: Created an interactive HTML client (index.html) with:
- Left panel: SSE receiver for subscribing to topics
- Right panel: Event publisher for sending events
6. Unit Tests: Implemented tests verifying:
- User1 subscribes to topic A, User2 to topic B - only User1 receives topic A messages
- User3 connects late and receives historical events (up to 100)
The project is ready to run with ./gradlew bootRun and includes full documentation.
