Preserved Critical Knowledge +- **Static Rendering**: Blocks use `innerHTML` in `firstUpdated` to prevent focus loss during typing +- **Shadow DOM Selection**: Implemented `containsAcrossShadowDOM` utility for proper selection detection +- **Cursor Position Tracking**: All editable blocks track cursor position across multiple events +- **Content Splitting**: HTML-aware splitting using Range API preserves formatting +- **Focus Management**: Microtask-based focus restoration ensures reliable cursor placement + +### 2. Enhanced Architecture +- Each block type is now self-contained in its own file +- Block handlers are dynamically registered and loaded +- Common functionality is shared through base classes +- Styles are co-located with their block handlers + +### 3. Maintained Functionality +- All keyboard navigation works (arrows, backspace, delete, enter) +- Text selection across Shadow DOM boundaries functions correctly +- Block merging and splitting behave as before +- IME (Input Method Editor) support is preserved +- Formatting shortcuts (Cmd/Ctrl+B/I/U/K) continue to work + +## Code Organization + +``` +ts_web/elements/wysiwyg/ +├── dees-wysiwyg-block.ts (simplified main component) +├── wysiwyg.selection.ts (Shadow DOM selection utilities) +├── wysiwyg.blockregistration.ts (handler registration) +└── blocks/ + ├── index.ts (exports and registry) + ├── block.base.ts (base handler interface) + ├── decorative/ + │ └── divider.block.ts + └── text/ + ├── paragraph.block.ts + ├── heading.block.ts + ├── quote.block.ts + ├── code.block.ts + └── list.block.ts +``` + +## Next Steps + +### Phase 4: Media Blocks (In Progress) +- Image block with upload/drag-drop support +- YouTube block with video embedding +- Attachment block for file uploads + +### Phase 5: Content Blocks +- Markdown block with preview toggle +- HTML block with raw HTML editing + +### Phase 6: Cleanup +- Remove old code from main component +- Optimize bundle size +- Update documentation + +## Technical Improvements + +1. **Modularity**: Each block type is now completely self-contained +2. **Extensibility**: New blocks can be added by creating a handler and registering it +3. **Maintainability**: Files are smaller and focused on single responsibilities +4. **Type Safety**: Strong TypeScript interfaces ensure consistent implementation +5. **Performance**: No degradation in performance; potential for lazy loading in future + +## Migration Pattern + +For future block migrations, follow this pattern: + +1.

These patterns and solutions took significant effort to discover and MUST be preserved during refactoring. + +## 1. Static Rendering to Prevent Focus Loss + +### Problem +When using Lit's reactive rendering, every state change would cause a re-render, which would: +- Lose cursor position +- Lose focus state +- Interrupt typing +- Break IME (Input Method Editor) support + +### Solution +We render blocks **statically** and manage updates imperatively: + +```typescript +// In dees-wysiwyg-block.ts +render(): TemplateResult { + if (!this.block) return html``; + // Render empty container - content set in firstUpdated + return html`
`; +} + +firstUpdated(): void { + const container = this.shadowRoot?.querySelector('.wysiwyg-block-container'); + if (container && this.block) { + container.innerHTML = this.renderBlockContent(); + } +} +``` + +### Critical Pattern +- NEVER use reactive properties that would trigger re-renders during typing +- Use `shouldUpdate()` to prevent unnecessary renders +- Manage content updates imperatively through event handlers + +## 2. Shadow DOM Selection Handling + +### Problem +The Web Selection API doesn't work across Shadow DOM boundaries by default. This broke: +- Text selection +- Cursor position tracking +- Formatting detection +- Content splitting for Enter key + +### Solution +Use the `getComposedRanges` API with all relevant shadow roots: + +```typescript +// From paragraph.block.ts +const wysiwygBlock = element.closest('dees-wysiwyg-block'); +const parentComponent = wysiwygBlock?.closest('dees-input-wysiwyg'); +const parentShadowRoot = parentComponent?.shadowRoot; +const blockShadowRoot = (wysiwygBlock as any)?.shadowRoot; + +const shadowRoots: ShadowRoot[] = []; +if (parentShadowRoot) shadowRoots.push(parentShadowRoot); +if (blockShadowRoot) shadowRoots.push(blockShadowRoot); + +const selectionInfo = WysiwygSelection.getSelectionInfo(...shadowRoots); +``` + +### Critical Pattern +- ALWAYS collect all shadow roots in the hierarchy +- Use `WysiwygSelection` utility methods that handle shadow DOM +- Never use raw `window.getSelection()` without shadow root context + +## 3. Cursor Position Tracking + +### Problem +Cursor position would be lost during various operations, making it impossible to: +- Split content at the right position for Enter key +- Restore cursor after operations +- Track position for formatting + +### Solution +Track cursor position through multiple events and maintain `lastKnownCursorPosition`: + +```typescript +// Track on every relevant event +private lastKnownCursorPosition: number = 0; + +// In event handlers: +const pos = this.getCursorPosition(element); +if (pos !== null) { + this.lastKnownCursorPosition = pos; +} + +// Fallback when selection not available: +if (!selectionInfo && this.lastKnownCursorPosition !== null) { + // Use last known position +} +``` + +### Critical Events to Track +- `input` - After text changes +- `keydown` - Before key press +- `keyup` - After key press +- `mouseup` - After mouse selection +- `click` - With setTimeout(0) for browser to set cursor + +## 4. Content Splitting for Enter Key + +### Problem +Splitting content at cursor position while preserving HTML formatting was complex due to: +- Need to preserve formatting tags +- Shadow DOM complications +- Cursor position accuracy + +### Solution +Use Range API to split content while preserving HTML: + +```typescript +getSplitContent(): { before: string; after: string } | null { + // Create ranges for before and after cursor + const beforeRange = document.createRange(); + const afterRange = document.createRange(); + + beforeRange.setStart(element, 0); + beforeRange.setEnd(selectionInfo.startContainer, selectionInfo.startOffset); + + afterRange.setStart(selectionInfo.startContainer, selectionInfo.startOffset); + afterRange.setEnd(element, element.childNodes.length); + + // Extract HTML content + const beforeFragment = beforeRange.cloneContents(); + const afterFragment = afterRange.cloneContents(); + + // Convert to HTML strings + const tempDiv = document.createElement('div'); + tempDiv.appendChild(beforeFragment); + const beforeHtml = tempDiv.innerHTML; + + tempDiv.innerHTML = ''; + tempDiv.appendChild(afterFragment); + const afterHtml = tempDiv.innerHTML; + + return { before: beforeHtml, after: afterHtml }; +} +``` + +## 5. Focus Management + +### Problem +Focus would be lost or not properly set due to: +- Timing issues with DOM updates +- Shadow DOM complications +- Browser inconsistencies + +### Solution +Use defensive focus management with fallbacks: + +```typescript +focus(element: HTMLElement): void { + const block = element.querySelector('.block'); + if (!block) return; + + // Ensure focusable + if (!block.hasAttribute('contenteditable')) { + block.setAttribute('contenteditable', 'true'); + } + + block.focus(); + + // Fallback with microtask if focus failed + if (document.activeElement !== block && element.shadowRoot?.activeElement !== block) { + Promise.resolve().then(() => { + block.focus(); + }); + } +} +``` + +## 6. Selection Event Handling for Formatting + +### Problem +Need to show formatting menu when text is selected, but selection events don't bubble across Shadow DOM. + +### Solution +Dispatch custom events with selection information: + +```typescript +// Listen for selection changes +document.addEventListener('selectionchange', () => { + const selectionInfo = WysiwygSelection.getSelectionInfo(...shadowRoots); + + if (selectedText !== this.lastSelectedText) { + const range = WysiwygSelection.createRangeFromInfo(selectionInfo); + const rect = range.getBoundingClientRect(); + + // Dispatch custom event + this.dispatchSelectionEvent(element, { + text: selectedText, + blockId: block.id, + range: range, + rect: rect, + hasSelection: true + }); + } +}); + +// Custom event bubbles through Shadow DOM +const event = new CustomEvent('block-text-selected', { + detail, + bubbles: true, + composed: true +}); +``` + +## 7. IME (Input Method Editor) Support + +### Problem +Composition events for non-Latin input methods would break without proper handling. + +### Solution +Track composition state and handle events: + +```typescript +// In dees-input-wysiwyg.ts +public isComposing: boolean = false; + +// In block handlers +element.addEventListener('compositionstart', () => { + handlers.onCompositionStart(); // Sets isComposing = true +}); + +element.addEventListener('compositionend', () => { + handlers.onCompositionEnd(); // Sets isComposing = false +}); + +// Don't process certain operations during composition +if (this.isComposing) return; +``` + +## 8. Programmatic Rendering + +### Problem +Lit's declarative rendering would cause focus loss and performance issues with many blocks. + +### Solution +Render blocks programmatically: + +```typescript +public renderBlocksProgrammatically() { + if (!this.editorContentRef) return; + + // Clear existing blocks + this.editorContentRef.innerHTML = ''; + + // Create and append block elements + this.blocks.forEach(block => { + const blockWrapper = this.createBlockElement(block); + this.editorContentRef.appendChild(blockWrapper); + }); +} +``` + +## 9.
