Room Subscription Manager

Unified room-based subscription tracking with automatic cleanup and duplicate prevention. Used by StreamWebSocketService to track which rooms (token subscriptions, pools, etc.) are currently active.

Features:

  • Duplicate prevention (can't add same room twice)
  • O(1) subscription checks
  • Bulk retrieval of subscribed rooms
  • Automatic cleanup on unsubscribe

Example​

// Test case: Room tracking with subscription metadata
const manager = new RoomSubscriptionManager();

// Add room
manager.addRoom('token:anime');
console.assert(manager.isSubscribedTo('token:anime') === true);

// Prevent duplicates (no-op if already added)
manager.addRoom('token:anime'); // Silent duplicate prevention

// Get all subscribed rooms
const rooms = manager.getRooms();
console.assert(rooms.includes('token:anime'));

// Remove room
manager.removeRoom('token:anime');
console.assert(manager.isSubscribedTo('token:anime') === false);

// Clear all
manager.addRoom('room1');
manager.addRoom('room2');
manager.clear();
console.assert(manager.getRooms().length === 0);
