 # Changelog

+## 2025-12-19 - 3.4.0 - feat(dees-appui-base)
+overhaul AppUI core: replace simple view rendering with a full-featured ViewRegistry (caching, hide/show lifecycle, async lazy-loading), introduce view lifecycle hooks and activation context, add activity log API/component, remove built-in router and state manager, and update configuration interfaces and demos
+
+- Removed files: app.router.ts and state.manager.ts — routing and state-persistence internals were removed (breaking).
+- ViewRegistry rewritten: supports cached instances, activate/deactivate lifecycle, canDeactivate checks, async content loading, parameterized routes, and legacy renderView kept as deprecated compatibility.
+- New interfaces added/changed: IViewActivationContext, IViewLifecycle, IActivityEntry, IActivityLogAPI, IViewLifecycleEvent; IViewDefinition.content now accepts async loaders and a cache flag; IMainMenuConfig and ITab expanded (logo, groups, badges).
+- Activity log: dees-appui-activitylog now implements IActivityLogAPI and exposes reactive entries; demo and readme updated with usage and examples.
+- App config changed: routing and statePersistence config entries removed/adjusted; defaultView moved into IAppConfig; view change and lifecycle event shapes changed (breaking).
+- Demos and documentation: dees-appui-base demo and readme added/updated to showcase new lifecycle hooks, secondary menu behavior, activity log and new APIs.
+
+## 2025-12-19 - 3.3.3 - fix(tests)
+update test imports to new dees-input-wysiwyg paths
+
+- Updated imports in test/test.wysiwyg-registry.both.ts to point to ts_web/elements/00group-input/dees-input-wysiwyg/*
+- Aligns test references with relocated WYSIWYG block handlers and block registration module; no behavior changes to implementation
+
+## 2025-12-19 - 3.3.2 - fix(build)
+update build config, bump dependencies, and adjust test import paths after element reorganization
+
+- npmextra.json: renamed gitzone entry to @git.zone/cli, moved tsdoc key to @git.zone/tsdoc, added @ship.zone/szci entry and added release registries + accessLevel
+- package.json: bumped @design.estate/dees-wcctools ^2.0.1 -> ^3.1.0, lucide ^0.560.0 -> ^0.562.0, @git.zone/tsbuild ^3.1.2 -> ^4.0.2, @types/node ^25.0.0 -> ^25.0.3
+- tests: updated import paths to follow reorganized source layout (wysiwyg files moved under elements/00group-input/dees-input-wysiwyg and dees-contextmenu moved to elements/dees-contextmenu/dees-contextmenu.js); updated BlockRegistry and blockregistration import paths
+- Purpose: align tests and build metadata with refactored element file locations and updated tool/dependency versions
+
+## 2025-12-11 - 3.3.1 - fix(dees-pdf-viewer)
+Scroll active PDF thumbnail into view after rendering and on page changes; update dependency versions
+
+- Ensure the active thumbnail is scrolled into view after thumbnails are rendered (improves sidebar navigation for dees-pdf-viewer).
+- Scroll the thumbnail into view when navigating pages if the sidebar is visible (prevents the active page from being off-screen).
+- Retain re-setup of the intersection observer for lazy-loading pages after thumbnail re-render.
+- Bumped dependencies in package.json: @design.estate/dees-wcctools -> ^2.0.1, lucide -> ^0.560.0, @git.zone/tswatch -> ^2.3.13, @types/node -> ^25.0.0.
+
+## 2025-12-09 - 3.3.0 - feat(dees-appui-base)
+Add unified App UI API to dees-appui-base with ViewRegistry, AppRouter and StateManager
+
+- Introduce ViewRegistry for declarative view registration and rendering (supports tag names, element classes and template functions).
+- Add AppRouter with hash/history/external/none modes, URL synchronization, navigate/back/forward and onRouteChange listener support.
+- Add StateManager to persist UI state (localStorage, sessionStorage or in-memory) with save/load/update/clear APIs.
+- Extend interfaces (interfaces/appconfig.ts) with IAppConfig, IViewDefinition, IRoutingConfig, IStatePersistenceConfig and IAppUIState.
+- Expose new public DeesAppuiBase methods: configure, navigateToView, getCurrentView, getUIState, restoreUIState, saveState, loadState, getViewRegistry, getRouter.
+- Maintain backward compatibility with existing property-based API and slot usage.
+- Export new modules (view.registry, app.router, state.manager) from dees-appui-base index and update element exports.
+
 ## 2025-12-08 - 3.2.0 - feat(dees-simple-appdash,dees-simple-login,dees-terminal)
 Revamp UI: dashboard & login styling, standardize icons to Lucide, and add terminal background/config

+## Enhanced AppUI API (2025-12-08)
+
+The `dees-appui-base` component has been enhanced with a unified configuration API for building real-world applications.
+
+### New Modules:
+
+1. **ViewRegistry** (`view.registry.ts`)
+   - Manages view definitions and their lifecycle
+   - Supports tag names, element classes, and template functions as view content
+   - Methods: register, get, renderView, findByRoute
+
+2. **AppRouter** (`app.router.ts`)
+   - Built-in routing with hash or history mode
+   - External router support for framework integration
+   - Methods: navigate, back, forward, onRouteChange
+
+3. **StateManager** (`state.manager.ts`)
+   - Persists UI state (collapsed menus, selections, current view)
+   - Supports localStorage, sessionStorage, or memory storage
+   - Methods: save, load, update, clear
+
+### New Interfaces (in `interfaces/appconfig.ts`):
+
+```typescript
+interface IAppConfig {
+  branding?: { logoIcon?: string; logoText?: string };
+  appBar?: IAppBarConfig;
+  views: IViewDefinition[];
+  mainMenu?: IMainMenuConfig;
+  routing?: IRoutingConfig;
+  statePersistence?: IStatePersistenceConfig;
+  onViewChange?: (viewId: string, view: IViewDefinition) => void;
+}
+
+interface IViewDefinition {
+  id: string;
+  name: string;
+  iconName?: string;
+  content: string | (new () => HTMLElement) | (() => TemplateResult);
+  secondaryMenu?: ISecondaryMenuGroup[];
+  contentTabs?: ITab[];
+  route?: string;
+}
+
+interface IRoutingConfig {
+  mode: 'hash' | 'history' | 'external' | 'none';
+  basePath?: string;
+  defaultView?: string;
+  syncUrl?: boolean;
+}
+```
+
+### New Public Methods on DeesAppuiBase:
+
+```typescript
+// Configure with unified config
+configure(config: IAppConfig): void
+
+// Navigation
+navigateToView(viewId: string): boolean
+getCurrentView(): IViewDefinition | undefined
+
+// State management
+getUIState(): IAppUIState
+restoreUIState(state: IAppUIState): void
+saveState(): void
+loadState(): boolean
+
+// Access internals
+getViewRegistry(): ViewRegistry
+getRouter(): AppRouter | null
+```
+
+### Usage Example (New Unified Config API):
+
+```typescript
+import type { IAppConfig } from '@design.estate/dees-catalog';
+
+const config: IAppConfig = {
+  branding: { logoIcon: 'lucide:box', logoText: 'My App' },

+`;
+```
+
+### Key Features:
+
+- **Declarative View Registry**: Map menu items to view components
+- **Built-in Routing**: Hash or history mode with URL synchronization
+- **External Router Support**: Integrate with Angular Router or other frameworks
+- **State Persistence**: Save/restore collapsed menus, selections, and current view
+- **View-specific Menus**: Each view can define its own secondary menu and tabs
+- **Full Backward Compatibility**: Existing code continues to work

+# DeesAppuiBase
+
+A comprehensive application shell component providing a complete UI framework with navigation, menus, activity logging, and view management.
+
+## Quick Start
+
+```typescript
+import { html, DeesElement, customElement } from '@design.estate/dees-element';
+import { DeesAppuiBase } from '@design.estate/dees-catalog';
+
+@customElement('my-app')
+class MyApp extends DeesElement {
+  private appui: DeesAppuiBase;
+
+  async firstUpdated() {
+    this.appui = this.shadowRoot.querySelector('dees-appui-base');
+
+    // Configure with views and menu
+    this.appui.configure({
+      branding: { logoIcon: 'lucide:box', logoText: 'My App' },
+      views: [
+        { id: 'dashboard', name: 'Dashboard', iconName: 'lucide:home', content: 'my-dashboard' },
+        { id: 'settings', name: 'Settings', iconName: 'lucide:settings', content: 'my-settings' },
+      ],
+      mainMenu: {

+    });
+  }
+
+  render() {
+    return html`<dees-appui-base></dees-appui-base>`;
+  }
+}
+```
+
+## Configuration API
+
+### `configure(config: IAppConfig)`
+
+Configure the entire application shell with a single configuration object.
+
+```typescript
+interface IAppConfig {
+  branding?: IBrandingConfig;
+  appBar?: IAppBarConfig;
+  views: IViewDefinition[];
+  mainMenu?: IMainMenuConfig;
+  defaultView?: string;
+  activityLog?: IActivityLogConfig;
+  onViewChange?: (viewId: string, view: IViewDefinition) => void;
+  onSearch?: (query: string) => void;
+}
+```
+
+### View Definition
+
+```typescript
+interface IViewDefinition {
+  id: string;                           // Unique identifier
+  name: string;                         // Display name
+  iconName?: string;                    // Icon (e.g., 'lucide:home')
+  content:                              // View content
+    | string                            // Tag name ('my-component')
+    | (new () => HTMLElement)           // Class constructor
+    | (() => TemplateResult)            // Template function
+    | (() => Promise<...>);             // Async for lazy loading
+  secondaryMenu?: ISecondaryMenuGroup[];
+  contentTabs?: ITab[];
+  route?: string;                       // URL route (default: id)
+  badge?: string | number;
+  cache?: boolean;                      // Cache view instance (default: true)
+}
+```
+
+---
+
+## Programmatic APIs
+
+### App Bar API
+
+Control the top application bar.
+
+```typescript
+// Set menu items (File, Edit, View, etc.)
+appui.setAppBarMenus([
+  {
+    name: 'File',
+    submenu: [
+      { name: 'New', shortcut: 'Cmd+N', action: () => {} },
+      { name: 'Save', shortcut: 'Cmd+S', action: () => {} },
+    ]
+  }
+]);
+
+// Update single menu
+appui.updateAppBarMenu('File', { submenu: [...newItems] });
+
+// Breadcrumbs
+appui.setBreadcrumbs('Dashboard > Settings > Profile');
+appui.setBreadcrumbs(['Dashboard', 'Settings', 'Profile']);
+
+// User profile
+appui.setUser({
+  name: 'John Doe',
+  email: 'john@example.com',
+  avatar: '/avatars/john.png',
+  status: 'online'  // 'online' | 'offline' | 'busy' | 'away'
+});
+
+appui.setProfileMenuItems([
+  { name: 'Profile', iconName: 'lucide:user', action: () => {} },
+  { divider: true },
+  { name: 'Sign Out', iconName: 'lucide:log-out', action: () => {} }
+]);
+
+// Search
+appui.setSearchVisible(true);
+appui.onSearch((query) => console.log('Search:', query));
+
+// Window controls (for Electron/Tauri apps)
+appui.setWindowControlsVisible(false);
+```
+
+### Main Menu API (Left Sidebar)
+
+Control the main navigation menu.
+
+```typescript
+// Set entire menu
+appui.setMainMenu({
+  logoIcon: 'lucide:box',
+  logoText: 'My App',
+  groups: [
+    {
+      name: 'Main',
+      tabs: [
+        { key: 'dashboard', iconName: 'lucide:home', action: () => {} },
+        { key: 'inbox', iconName: 'lucide:inbox', badge: 5, action: () => {} },
+      ]
+    }
+  ],
+  bottomTabs: [
+    { key: 'settings', iconName: 'lucide:settings', action: () => {} }
+  ]
+});
+
+// Update specific group
+appui.updateMainMenuGroup('Main', { tabs: [...newTabs] });
+
+// Add/remove items
+appui.addMainMenuItem('Main', { key: 'tasks', iconName: 'lucide:check', action: () => {} });
+appui.removeMainMenuItem('Main', 'tasks');
+
+// Selection
+appui.setMainMenuSelection('dashboard');
+appui.setMainMenuCollapsed(true);
+
+// Badges
+appui.setMainMenuBadge('inbox', 12);
+appui.clearMainMenuBadge('inbox');
+```
+
+### Secondary Menu API
+
+Views can control the secondary (contextual) menu.
+
+```typescript
+// Set menu
+appui.setSecondaryMenu({
+  heading: 'Settings',
+  groups: [
+    {
+      name: 'Account',
+      items: [
+        { key: 'profile', iconName: 'lucide:user', action: () => {} },
+        { key: 'security', iconName: 'lucide:shield', action: () => {} },
+      ]
+    }
+  ]
+});
+
+// Update group
+appui.updateSecondaryMenuGroup('Account', { items: newItems });
+
+// Add item
+appui.addSecondaryMenuItem('Account', {
+  key: 'notifications',
+  iconName: 'lucide:bell',
+  action: () => {}
+});
+
+// Selection
+appui.setSecondaryMenuSelection('profile');
+
+// Clear
+appui.clearSecondaryMenu();
+```
+
+### Content Tabs API
+
+Control tabs in the main content area.
+
+```typescript
+// Set tabs
+appui.setContentTabs([
+  { key: 'code', iconName: 'lucide:code', action: () => {} },
+  { key: 'preview', iconName: 'lucide:eye', action: () => {} }
+]);
+
+// Add/remove
+appui.addContentTab({ key: 'debug', iconName: 'lucide:bug', action: () => {} });
+appui.removeContentTab('debug');
+
+// Select
+appui.selectContentTab('preview');
+
+// Get current
+const current = appui.getSelectedContentTab();
+```
+
+### Activity Log API
+
+Add activity entries to the right-side activity log.
+
+```typescript
+// Add single entry
+appui.activityLog.add({
+  type: 'create',       // 'login' | 'logout' | 'view' | 'create' | 'update' | 'delete' | 'custom'
+  user: 'John Doe',
+  message: 'created a new invoice',
+  iconName: 'lucide:file-plus',  // Optional custom icon
+  data: { invoiceId: '123' }     // Optional metadata
+});
+
+// Add multiple
+appui.activityLog.addMany([...entries]);
+
+// Clear
+appui.activityLog.clear();
+
+// Query
+const entries = appui.activityLog.getEntries();
+const filtered = appui.activityLog.filter({ user: 'John', type: 'create' });
+const searched = appui.activityLog.search('invoice');
+```
+
+### Navigation API
+
+Navigate between views programmatically.
+
+```typescript
+// Navigate to view
+await appui.navigateToView('settings');
+await appui.navigateToView('settings', { section: 'profile' });
+
+// Get current view
+const current = appui.getCurrentView();
+
+// Subscribe to view changes
+appui.viewChanged$.subscribe((event) => {
+  console.log(`Navigated to: ${event.viewId}`);
+});
+
+// Subscribe to lifecycle events
+appui.viewLifecycle$.subscribe((event) => {
+  if (event.type === 'activated') {
+    console.log(`View ${event.viewId} activated`);
+  }
+});
+```
+
+---
+
+## View Lifecycle Hooks
+
+Views can implement lifecycle hooks to respond to activation/deactivation.
+
+```typescript
+import { DeesElement, customElement } from '@design.estate/dees-element';
+import type { IViewActivationContext, IViewLifecycle } from '@design.estate/dees-catalog';
+
+@customElement('my-settings-view')
+class MySettingsView extends DeesElement implements IViewLifecycle {
+  /**
+   * Called when view is activated (displayed)
+   * Receives typed context with appui reference
+   */
+  async onActivate(context: IViewActivationContext) {
+    const { appui, viewId, params } = context;
+
+    // Set view-specific secondary menu
+    appui.setSecondaryMenu({
+      heading: 'Settings',
+      groups: [{ name: 'Options', items: [...] }]
+    });
+
+    // Set view-specific tabs
+    appui.setContentTabs([...]);
+
+    // Load data based on route params
+    if (params?.section) {
+      await this.loadSection(params.section);
+    }
+  }
+
+  /**
+   * Called when view is deactivated (hidden)
+   */
+  onDeactivate() {
+    this.cleanup();
+  }
+
+  /**
+   * Called before navigation away
+   * Return false or a message string to block navigation
+   */
+  canDeactivate(): boolean | string {
+    if (this.hasUnsavedChanges) {
+      return 'You have unsaved changes. Leave anyway?';
+    }
+    return true;
+  }
+}
+```
+
+### IViewActivationContext
+
+```typescript
+interface IViewActivationContext {
+  appui: DeesAppuiBase;           // Reference to the app shell
+  viewId: string;                  // The view ID being activated
+  params?: Record<string, string>; // Route parameters
+}
+```
+
+---
+
+## Routing
+
+Routes are automatically registered from view definitions using `domtools.router`.
+
+```typescript
+const views = [
+  { id: 'dashboard', route: 'dashboard', ... },
+  { id: 'settings', route: 'settings/:section?', ... },  // Parameterized
+  { id: 'user', route: 'users/:id', ... },
+];
+
+// URL: #dashboard → navigates to dashboard view
+// URL: #settings/profile → navigates to settings with params.section = 'profile'
+// URL: #users/123 → navigates to user with params.id = '123'
+```
+
+### Hash-based Routing
+
+The router uses hash-based routing by default (`#viewId`). URLs are automatically synchronized when navigating via `navigateToView()`.
+
+---
+
+## View Caching
+
+Views are cached by default. When navigating away and back, the same DOM element is reused (hidden/shown) rather than destroyed and recreated.
+
+```typescript
+// Disable caching for a specific view
+{
+  id: 'reports',
+  name: 'Reports',
+  content: 'my-reports-view',
+  cache: false  // Always recreate this view
+}
+```
+
+---
+
+## Lazy Loading
+
+Use async content functions for lazy loading views.
+
+```typescript
+{
+  id: 'analytics',
+  name: 'Analytics',
+  content: async () => {
+    const module = await import('./views/analytics.js');
+    return module.AnalyticsView;
+  }
+}
+```
+
+---
+
+## RxJS Observables
+
+The component exposes RxJS Subjects for reactive programming.
+
+```typescript
+// View lifecycle events
+appui.viewLifecycle$.subscribe((event) => {
+  // event.type: 'loading' | 'activated' | 'deactivated' | 'loaded' | 'loadError'
+  // event.viewId: string
+  // event.element?: HTMLElement
+  // event.params?: Record<string, string>
+  // event.error?: unknown
+});
+
+// View change events
+appui.viewChanged$.subscribe((event) => {
+  // event.viewId: string
+  // event.view: IViewDefinition
+  // event.previousView?: IViewDefinition
+  // event.params?: Record<string, string>
+});
+```
+
+---
+
