feat: add real-time updates via SSE (Server-Sent Events)#26
Merged
Conversation
This adds real-time functionality to the blog, so pages update automatically when content changes without requiring users to refresh. Changes: - Add events package for publishing blog events (posts/comments CRUD) - Posts service publishes events on create/update/delete - Comments service publishes events on create/delete - Web service includes SSE endpoint at /events - Frontend JavaScript connects via EventSource for live updates - CSS animations for new/updated/deleted content - Notification toasts for new posts The implementation uses go-micro's broker for pub/sub, which works with the default HTTP broker locally and can use NATS in production. Frontend features: - Automatic reconnection on disconnect - New posts appear at top of feed with animation - Updated posts flash to indicate changes - Deleted posts fade out - New comments appear in real-time on post pages - Toast notifications for new content This addresses the real-time requirements discussed in micro/go-micro#2788 Co-authored-by: Shelley <shelley@exe.dev>
