Boundaries (STRICT)

Registries (Singletons)

// ModuleRegistry - widget definitions
ModuleRegistry.register(todoModule)
ModuleRegistry.get('todo') // → ModuleDefinition

// ActionRegistry - user actions
ActionRegistry.register({ id: 'duplicate', ... })
ActionRegistry.execute('duplicate')

// DataContractRegistry - data sharing contracts
DataContractRegistry.register('boardkit.todo.v1', schema)

// DataBus - runtime pub/sub
DataBus.publish('boardkit.todo.v1', data)
DataBus.subscribe('boardkit.todo.v1', callback)

Stores (Pinia)

// boardStore - document state
boardStore.widgets        // Widget[]
boardStore.elements       // CanvasElement[]
boardStore.selectedIds    // Set<string>
boardStore.viewport       // { x, y, zoom }
boardStore.isDirty        // boolean
boardStore.addWidget(module, position)
boardStore.updateWidgetState(id, state)

// toolStore - tool state
toolStore.activeTool      // 'select' | 'hand' | 'rectangle' | ...
toolStore.isDrawing       // boolean
toolStore.setTool(tool)

Document Schema (v2)

interface BoardkitDocument {
  version: 2
  meta: { title, createdAt, updatedAt }
  board: {
    viewport: { x, y, zoom }
    widgets: Widget[]
    elements: CanvasElement[]
    background: BoardBackground
  }
  modules: Record<string, unknown>
  dataSharing?: { permissions[], links[] }
}

Module System

const myModule = defineModule<MyState>({
  id: 'my-module',
  displayName: 'My Module',
  icon: 'box',
  category: 'productivity',
  defaultWidth: 300,
  defaultHeight: 200,
  minWidth: 200,
  minHeight: 150,
  defaultState: () => ({ items: [] }),
  serialize: (state) => state,
  deserialize: (data) => data as MyState,
  component: () => import('./MyWidget.vue')
})
