Widget System Production-Ready Refactor

Complete refactor of the widget documentation system with reusable components, modular architecture, and production-ready UX

Widget System Production-Ready Refactor

🎯 Overview

Complete transformation of the widget documentation and variant management system to achieve production-ready quality with:

🧩 New Reusable Components

1. WidgetPropertiesTableComponent

Location: libs/libs-widgets/widget-showcase/src/lib/components/widget-properties-table/

Purpose: Display widget inputs and outputs in a standardized, production-ready format.

Features:

Usage:

<lib-widget-properties-table
  [inputs]="component.inputs"
  [outputs]="component.outputs"
  [title]="'Properties'"
  [collapsible]="true"
  [initiallyExpanded]="true">
</lib-widget-properties-table>

Interface:

export interface WidgetPropertyInput {
  name: string;
  type: string;
  default?: any;
  description: string;
}

export interface WidgetPropertyOutput {
  name: string;
  description: string;
}

2. CodeBlockComponent

Location: libs/libs-widgets/widget-showcase/src/lib/components/code-block/

Purpose: Display code snippets with copy functionality and syntax awareness.

Features:

Usage:

<lib-code-block
  [code]="component.usage"
  [title]="'Basic Usage'"
  [language]="'html'"
  [collapsible]="true"
  [initiallyExpanded]="true"
  [showLineNumbers]="false">
</lib-code-block>

🎨 CoreComponentDetailComponent Improvements

Location: libs/libs-widgets/widget-showcase/src/lib/components/core-component-detail/

New Features

1. Consolidated Live Previews

2. Variant Actions

Each variant card now includes:

Action Behavior:

// Edit - navigates to full-page editor
editVariant(variant: ComponentVariant) {
  this.router.navigate(['/space', spaceId, 'widgets', 'variant-editor', componentId, variant.id]);
}

// Duplicate - opens modal for quick duplication
duplicateVariant(variant: ComponentVariant) {
  this.variantCreatorModal.open({ mode: 'duplicate', ... });
}

3. Global Expand/Collapse Control

Implementation:

// Section state management
readonly allSectionsExpanded = signal(true);
readonly sectionsState = signal({
  usage: true,
  properties: true,
  bestPractices: true,
  related: true
});

// Toggle all sections
toggleAllSections(): void {
  const newState = !this.allSectionsExpanded();
  this.allSectionsExpanded.set(newState);
  this.sectionsState.set({
    usage: newState,
    properties: newState,
    bestPractices: newState,
    related: newState
  });
}

4. Collapsible Sections

All major sections are now collapsible:

Accessibility:

🏗️ Modular Architecture Alignment

All components follow the GoGrab Space Modular Architecture principles:

1. Self-Contained Components

@Component({
  selector: 'lib-widget-properties-table',
  standalone: true,  // ✅ Angular 20+ Standalone API
  imports: [CommonModule],  // ✅ Explicit imports
  templateUrl: './widget-properties-table.component.html',
  styleUrl: './widget-properties-table.component.scss'  // ✅ Separate files
})

2. Type Safety

3. Storage Integration

4. Communication Patterns

📐 UI/UX Improvements

Visual Design

Variant Cards

Collapsible Sections

Global Controls

Accessibility

All interactive elements include:

🔄 Variant Workflow

Complete CRUD Flow

graph LR
    A[Widget Guide] --> B[Component Detail]
    B --> C{User Action}
    C -->|Create| D[Modal: Smart Variant Creator]
    C -->|Edit| E[Full-Page: Variant Editor]
    C -->|Duplicate| D
    D --> F[Save to Storage]
    E --> F
    F --> G[Reload Variants]
    G --> B

1. Create Variant

2. Edit Variant

3. Duplicate Variant

📊 Performance Optimizations

1. Signal-Based Reactivity

// Efficient computed properties
readonly allVariants = computed((): ComponentVariant[] => {
  const data = this.componentData();
  const loaded = this.loadedVariants();
  // Merge and deduplicate
});

2. Lazy Loading

3. Efficient Rendering

🚀 Routes & Navigation

Widget Guide Routes

{
  path: 'guide',
  component: WidgetGuideComponent,
  children: [
    {
      path: ':componentId',
      component: CoreComponentDetailComponent
    }
  ]
},
{
  path: 'variant-editor/:componentId/:variantId',
  component: VariantBuilderPageComponent
}

Example URLs

📦 Exports & Integration

Barrel Exports

// libs/libs-widgets/widget-showcase/src/lib/components/index.ts
export * from './widget-properties-table/widget-properties-table.component';
export * from './code-block/code-block.component';
export * from './core-component-detail/core-component-detail.component';

Component Imports

// Usage in other components
import {
  WidgetPropertiesTableComponent,
  CodeBlockComponent
} from '@libs-widgets/widget-showcase/components';

🎯 Future Enhancements

Potential Improvements

  1. Syntax Highlighting: Add Prism.js or Highlight.js for code blocks
  2. Live Preview Rendering: Render actual widget components instead of HTML strings
  3. Search & Filter: Add search functionality for variants
  4. Variant Comparison: Side-by-side comparison of multiple variants
  5. Export/Import: Allow exporting variant configurations as JSON
  6. Variant History: Track changes and version history
  7. Collaborative Editing: Real-time collaboration on variant editing
