# Phase 2 Implementation Summary - Divider Block Migration
|
||
|
|
|
||
|
|
## Overview
|
||
|
|
Successfully migrated the divider block to the new block handler architecture as a proof of concept.
|
||
|
|
|
||
|
|
## Changes Made
|
||
|
|
|
||
|
|
### 1. Created Block Handler
|
||
|
|
- **File**: `blocks/content/divider.block.ts`
|
||
|
|
- Implemented `DividerBlockHandler` class extending `BaseBlockHandler`
|
||
|
|
- Extracted divider rendering logic from `dees-wysiwyg-block.ts`
|
||
|
|
- Extracted divider setup logic (event handlers)
|
||
|
|
- Extracted divider-specific styles
|
||
|
|
|
||
|
|
### 2. Registration System
|
||
|
|
- **File**: `wysiwyg.blockregistration.ts`
|
||
|
|
- Created registration module that registers all block handlers
|
||
|
|
- Currently registers only the divider handler
|
||
|
|
- Includes placeholders for future block types
|
||
|
|
|
||
|
|
### 3. Updated Block Component
|
||
|
|
- **File**: `dees-wysiwyg-block.ts`
|
||
|
|
- Added import for BlockRegistry and handler types
|
||
|
|
- Modified `renderBlockContent()` to check registry first
|
||
|
|
- Modified `firstUpdated()` to use registry for setup
|
||
|
|
- Added `injectHandlerStyles()` method to inject handler styles dynamically
|
||
|
|
- Removed hardcoded divider rendering logic
|
||
|
|
- Removed hardcoded divider styles
|
||
|
|
- Removed `setupDividerBlock()` method
|
||
|
|
|
||
|
|
### 4. Updated Exports
|
||
|
|
- **File**: `blocks/index.ts`
|
||
|
|
- Exported `DividerBlockHandler` class
|
||
|
|
|
||
|
|
## Key Features Preserved
|
||
|
|
✅ Visual appearance with gradient and icon
|
||
|
|
✅ Click to select behavior
|
||
|
|
✅ Keyboard navigation support (Tab, Arrow keys)
|
||
|
|
✅ Deletion with backspace/delete
|
||
|
|
✅ Focus/blur handling
|
||
|
|
✅ Proper styling for selected state
|
||
|
|
|
||
|
|
## Architecture Benefits
|
||
|
|
1. **Modularity**: Each block type is now self-contained
|
||
|
|
2. **Maintainability**: Block-specific logic is isolated
|
||
|
|
3. **Extensibility**: Easy to add new block types
|
||
|
|
4. **Type Safety**: Proper TypeScript interfaces
|
||
|
|
5. **Code Reuse**: Common functionality in BaseBlockHandler
|
||
|
|
|
||
|
|
## Next Steps
|
||
|
|
To migrate other block types, follow this pattern:
|
||
|
|
1. Create handler file in appropriate folder (text/, media/, content/)
|
||
|
|
2. Extract render logic, setup logic, and styles
|
||
|
|
3. Register in `wysiwyg.blockregistration.ts`
|
||
|
|
4. Remove hardcoded logic from `dees-wysiwyg-block.ts`
|
||
|
|
5. Export from `blocks/index.ts`
|
||
|
|
|
||
|
|
## Testing
|
||
|
|
- Project builds successfully without errors
|
||
|
|
- Existing tests pass
|
||
|
|
- Divider blocks render and function identically to before
