Data Flow

Initialization

  1. App starts → DataProvider initializes
  2. Socket.IO connection created with account number
  3. Server sends initial sync-clients event
  4. DataProvider updates state with 6 clients
  5. Components render with real data

Real-time Updates

  1. Data changes on server
  2. Server broadcasts Socket.IO event
  3. All clients receive update
  4. DataProvider updates local state
  5. Components re-render automatically

Fallback (No Socket.IO)

  1. DataProvider detects no connection
  2. Starts 30-second polling timer
  3. Fetches data via REST API
  4. Updates state as if it was a Socket.IO update
  5. Automatic reconnection attempted
