Lifecycle

Understand how the engine and plugins initialize and clean up.

Engine Lifecycle​

  1. Create CoreEngine
  2. Create Konva Stage and layers
  3. Initialize managers (NodeManager, CameraManager, VirtualizationManager)
  4. Attach plugins

Plugin Lifecycle​

import { Plugin, type CoreEngine } from "@flowscape-ui/core-sdk";

class MyPlugin extends Plugin {
  protected onAttach(core: CoreEngine) {
    // subscribe to events, add visuals, timers, etc.
  }
  protected onDetach(core: CoreEngine) {
    // unsubscribe, destroy visuals, clear timers
  }
}

Plugins are attached at engine construction time via the plugins option or later using the plugins registry.
