Architecture Overview

KuaDashboard uses a three-layer architecture: Backend API → Frontend SPA → Electron Shell (optional).

Data Flow

1. Vue components call the useApi composable for REST requests or useTerminalStreams for WebSocket connections
2. Pinia stores manage application state (Kubernetes, AWS, GCP, port forwards, terminals)
3. Express routes handle API requests by calling the appropriate SDK (K8s client, AWS SDK, GCP SDK)
4. WebSocket servers handle real-time streams (logs, exec, shell)
5. Electron (when used) wraps everything in a native window with an IPC bridge
