# Phase 4 Implementation Summary - Heading Blocks Migration
|
|
|
|
## Overview
|
|
Successfully migrated all heading blocks (h1, h2, h3) to the new block handler architecture using a unified HeadingBlockHandler class.
|
|
|
|
## Changes Made
|
|
|
|
### 1. Created Unified Heading Handler
|
|
- **File**: `blocks/text/heading.block.ts`
|
|
- Implemented `HeadingBlockHandler` class extending `BaseBlockHandler`
|
|
- Single handler class that accepts heading level (1, 2, or 3) in constructor
|
|
- Extracted all heading rendering logic from `dees-wysiwyg-block.ts`
|
|
- Extracted heading setup logic with full text editing support:
|
|
- Input handling with cursor tracking
|
|
- Selection handling with Shadow DOM support
|
|
- Focus/blur management
|
|
- Composition events for IME support
|
|
- Split content functionality
|
|
- Extracted all heading-specific styles for all three levels
|
|
|
|
### 2. Registration Updates
|
|
- **File**: `wysiwyg.blockregistration.ts`
|
|
- Registered three heading handlers using the same class:
|
|
- `heading-1` → `new HeadingBlockHandler('heading-1')`
|
|
- `heading-2` → `new HeadingBlockHandler('heading-2')`
|
|
- `heading-3` → `new HeadingBlockHandler('heading-3')`
|
|
- Updated imports to include HeadingBlockHandler
|
|
|
|
### 3. Updated Exports
|
|
- **File**: `blocks/index.ts`
|
|
- Exported `HeadingBlockHandler` class
|
|
- Removed TODO comment for heading handler
|
|
|
|
### 4. Handler Implementation Details
|
|
- **Dynamic Level Handling**: The handler determines the heading level from the block type
|
|
- **Shared Styles**: All heading levels share the same style method but render different CSS
|
|
- **Placeholder Support**: Each level has its own placeholder text
|
|
- **Full Text Editing**: Inherits all paragraph-like functionality:
|
|
- Cursor position tracking
|
|
- Text selection with Shadow DOM awareness
|
|
- Content splitting for Enter key handling
|
|
- Focus management with cursor positioning
|
|
|
|
## Key Features Preserved
|
|
✅ All three heading levels render with correct styles
|
|
✅ Font sizes: h1 (32px), h2 (24px), h3 (20px)
|
|
✅ Proper font weights and line heights
|
|
✅ Theme-aware colors using cssManager.bdTheme
|
|
✅ Contenteditable functionality
|
|
✅ Selection and cursor tracking
|
|
✅ Keyboard navigation
|
|
✅ Focus/blur handling
|
|
✅ Placeholder text for empty headings
|
|
|
|
## Architecture Benefits
|
|
1. **Code Reuse**: Single handler class for all heading levels
|
|
2. **Consistency**: All headings share the same behavior
|
|
3. **Maintainability**: Changes to heading behavior only need to be made once
|
|
4. **Type Safety**: Heading level is type-checked at construction
|
|
5. **Scalability**: Easy to add more heading levels if needed
|
|
|
|
## Testing Results
|
|
- ✅ TypeScript compilation successful
|
|
- ✅ All three heading handlers registered correctly
|
|
- ✅ Render method produces correct HTML with proper classes
|
|
- ✅ Placeholders set correctly for each level
|
|
- ✅ All handlers are instances of HeadingBlockHandler
|
|
|
|
## Next Steps
|
|
Continue with Phase 5 to migrate remaining text blocks:
|
|
- Quote block
|
|
- Code block
|
|
- List block
|
|
|
|
Each will follow the same pattern but with their specific requirements. |
