🏗️ Architecture: Perfect Modular System

1. Base Widget Component ✅

Location: @libs-widgets/widget-system/src/lib/components/base-widget/

Features:

• ✅ State machine with 7 states (idle → ready → active → destroyed)
• ✅ Lifecycle methods (onWidgetInit, onWidgetDestroy)
• ✅ Event system (emitWidgetEvent)
• ✅ Timeout protection (5-second default)
• ✅ Data binding support (optional)
• ✅ Error handling (hasError, error signals)
• ✅ Loading state (isLoading signal)
• ✅ Required widgetId input
• ✅ Optional widget input (for full widget data)

Usage:

export class MyWidgetComponent extends BaseWidgetComponent {
  readonly widget = input.required<Widget>();
  
  override onWidgetInit(): void {
    this.markReady();
  }
  
  override onWidgetDestroy(): void {
    // Cleanup
  }
}

5. Backend API ✅

Location: apis/backend-api/src/app/widgets/

Endpoints:

GET    /api/spaces/:spaceId/widgets              → List all widgets
GET    /api/spaces/:spaceId/widgets/:id          → Get widget by ID
POST   /api/spaces/:spaceId/widgets              → Create widget
PUT    /api/spaces/:spaceId/widgets/:id          → Update widget
DELETE /api/spaces/:spaceId/widgets/:id          → Delete widget
GET    /api/spaces/:spaceId/widgets/:id/variants → Get variants (ID or TYPE)
POST   /api/spaces/:spaceId/widgets/:id/variants → Create variant
PUT    /api/spaces/:spaceId/widgets/:id/variants/:variantId → Update variant
GET    /api/spaces/:spaceId/widgets/:id/embeddable → Get embeddable metadata
GET    /api/spaces/:spaceId/widgets/ai-context   → Get AI context

Smart Variants Endpoint:

• ✅ Handles widget ID lookups
• ✅ Handles widget TYPE lookups (e.g., "text")
• ✅ Aggregates variants across all widgets of a type
• ✅ Returns proper format for frontend

🎨 Perfect Reusable Building Blocks

Design Principles

1. Single Responsibility ✅

Each widget has ONE clear purpose:

• TextWidget → Display/edit text
• ButtonWidget → Trigger actions
• CardWidget → Container with styling
• InputWidget → Collect user input

2. Composability ✅

Widgets can be nested and combined:

<lib-card-widget [widgetId]="card.id" [widget]="card">
  <lib-text-widget [widgetId]="text.id" [widget]="text" />
  <lib-button-widget [widgetId]="btn.id" [widget]="btn" />
</lib-card-widget>

3. Embeddability ✅

All widgets are embeddables:

• ✅ Can be used in editor
• ✅ Can be used in page builder
• ✅ Can be used in modules
• ✅ Can be standalone components

4. Configurability ✅

All widgets support:

• ✅ Properties (widget config object)
• ✅ Variants (preset configurations)
• ✅ Layout (position, size, z-index)
• ✅ Styles (theme-aware CSS variables)
• ✅ Animations (optional motion)

5. Modularity ✅

Organized in NX libraries:

• @libs-widgets/widget-system → Base classes, models, services
• @libs-widgets/widgets → Widget implementations
• @libs-widgets/widget-showcase → Showcase UI & docs
• @libs-widgets/widget-builder → Builder tool
• @libs-widgets/widgets-manager → Management dashboard

🔧 Migration Pattern (Established)

Step 1: Import Base Class

import { BaseWidgetComponent } from '@libs-widgets/widget-system';

Step 2: Extend Base Class

export class MyWidgetComponent extends BaseWidgetComponent {
  // widgetId comes from base (automatic)
  readonly widget = input.required<Widget>();
}

Step 3: Add Lifecycle

override onWidgetInit(): void {
  this.markReady();
}

override onWidgetDestroy(): void {
  // Cleanup handled by base class
}

Step 4: Override ngOnDestroy (if needed)

override ngOnDestroy(): void {
  // Component-specific cleanup
  super.ngOnDestroy();
}

Step 5: Call super() in Constructor (if needed)

constructor() {
  super();
  // Component-specific initialization
}

Step 6: Override Signals (if conflicts)

// If BaseWidgetComponent has property with same name
override isLoading = signal<boolean>(true);
override hasError = signal<boolean>(false);

// Or rename to avoid conflict
videoError = signal<string | null>(null);

📋 Template Requirements

Always Provide widgetId

<!-- Static ID -->
<my-widget widgetId="my-static-id">

<!-- Dynamic from widget -->
<my-widget [widgetId]="widget().id">

<!-- For child widgets -->
<ui-button [widgetId]="widget().id + '-btn'">

<!-- In lists -->
<ui-button 
  *ngFor="let item of items" 
  [widgetId]="'item-' + item.id">

🎯 Success Metrics

🚀 Integration Points

1. Widget Discovery

WidgetsEmbeddableRegistryService.embeddables()
→ Returns all registered widgets from modules

2. Widget Rendering

// Dynamic component outlet
<ng-container *ngComponentOutlet="comp; inputs: getVariantInputs()">

3. Variant Management

// Backend API call
GET /api/spaces/{spaceId}/widgets/{widgetType}/variants
→ Returns all variants for widget type

// Frontend service
VariantBuilderService.getAllVariants({ widgetType: 'text' })

4. Module Integration
