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
