webui: convert sketch-call-status and sketch-chat-input to SketchTailwindElement with comprehensive demo support
Convert both sketch-call-status and sketch-chat-input components from shadow DOM CSS to Tailwind classes while maintaining test compatibility and adding comprehensive demo infrastructure.
Problems Solved:
Shadow DOM Styling Limitations:
- Both components used CSS-in-JS with shadow DOM preventing Tailwind integration
- Large static styles blocks with custom CSS duplicated Tailwind functionality
- Components couldn't benefit from design system consistency
- Difficult to maintain custom CSS alongside Tailwind-based components
Missing Demo Infrastructure:
- sketch-call-status had no demo fixtures for testing component states
- sketch-chat-input needed dedicated demo fixture following naming convention
- Components not properly integrated into demo runner system
Test Compatibility Issues:
- Conversion to Tailwind required updating shadow DOM selectors
- renderRoot.querySelector calls needed conversion to direct querySelector
- Component tests needed updating for non-shadow DOM structure
Solution Implementation:
Tailwind CSS Conversion - sketch-call-status:
- Changed sketch-call-status to inherit from SketchTailwindElement
- Replaced CSS-in-JS styles with Tailwind utility classes and inline animations
- Converted animations using @keyframes in inline <style> tag
- Maintained exact visual appearance while using Tailwind classes
Tailwind CSS Conversion - sketch-chat-input:
- Changed sketch-chat-input to inherit from SketchTailwindElement
- Replaced extensive static styles CSS block with Tailwind utility classes
- Converted complex chat container, input wrapper, and button styling
- Added custom fade-in animation to tailwind.config.js with keyframes
Key Tailwind Class Mappings:
- Call status indicators: bg-yellow-100 text-amber-500 (active), text-gray-400 (idle)
- Status banners: bg-green-50 text-green-700 (idle), bg-orange-50 text-orange-600 (working)
- Chat container: w-full bg-gray-100 p-4 min-h-[40px] relative
- Chat input: flex-1 p-3 border border-gray-300 rounded resize-y font-mono
- Send button: bg-blue-500 hover:bg-blue-600 disabled:bg-gray-400
Shadow DOM to Light DOM Conversion:
- Removed static styles properties completely
- Updated all renderRoot.querySelector calls to direct querySelector calls
- Changed shadow DOM event handler setup to work with light DOM
- Maintained all drag-and-drop and event handling functionality
Test Compatibility Maintenance:
- Added semantic CSS classes back to elements for test selectors
- Updated sketch-chat-input.test.ts to use querySelector instead of renderRoot.querySelector
- Fixed drag event simulation to work with light DOM structure
- All existing tests continue to pass with updated selectors
Demo Infrastructure Implementation:
- Created call-status.ts demo fixtures with CallStatusState interface
- Added comprehensive sketch-call-status.demo.ts with interactive controls
- Created chat-input.ts demo fixture with message display and controls
- Added both components to demo-runner.ts knownComponents list
Interactive Demo Features:
- Call status: Status variations, interactive LLM/tool call controls, connection toggle
- Chat input: Message display with user/bot styling, multiple preset buttons
- Both demos include real-time state updates and comprehensive examples
Dependencies:
- Added @tailwindcss/vite package for Tailwind integration
- Updated package.json and package-lock.json with new dependency
Files Modified:
- sketch/webui/src/web-components/sketch-call-status.ts: Converted to SketchTailwindElement
- sketch/webui/src/web-components/sketch-chat-input.ts: Converted to SketchTailwindElement
- sketch/webui/src/web-components/sketch-chat-input.test.ts: Updated selectors for light DOM
- sketch/webui/src/web-components/demo/demo-fixtures/call-status.ts: Added call status fixtures
- sketch/webui/src/web-components/demo/demo-fixtures/index.ts: Export call status fixtures
- sketch/webui/src/web-components/demo/sketch-call-status.demo.ts: Complete interactive demo
- sketch/webui/src/web-components/demo/chat-input.ts: New chat input demo fixture
- sketch/webui/src/web-components/demo/demo-framework/demo-runner.ts: Added both components
- sketch/webui/tailwind.config.js: Added custom fade-in animation
- sketch/webui/package.json: Added @tailwindcss/vite dependency
Testing and Validation:
- All component tests pass with updated selectors
- Components render correctly with Tailwind classes
- All functionality preserved including animations and interactions
- Interactive demos load and function properly
- Components appear in demo runner list
The conversion maintains all functionality while enabling better integration
with the Tailwind-based design system and providing comprehensive demo
infrastructure for development and testing.
