Command System & Event Bus

🧭 Command System & Event Bus

A global command and event system will allow modules and workers to:

• Dispatch standardized commands (e.g. openWindow('Mail'))
• Broadcast events (e.g. fit:parsed, fleet:update, token:expired)
• Listen and react without tight coupling

Command Pattern

window.dispatchEvent(new CustomEvent('app:command', {
  detail: {
    type: 'window:open',
    payload: { id: 'Mail', pinned: true }
  }
}));

Event listeners will be namespace-aware and scoped per module.

Event Bus Utility (Planned)

A shared bus module will:

• Standardize event dispatching and logging
• Allow hooks into UI (for notifications, log display)
• Enable worker-to-worker messages via proxy relay

This enables dynamic communication between otherwise isolated modules.

📌 Summary

• Background workers make the app feel fast and responsive
• Work is divided across logical domains (market, API, fleet, scan)
• The command system will unify control and communication across modules
• The event bus will act as an invisible glue between core services
