# CONFIG-002 Subtask 1: Core Panel + Identity & SEO Sections - CHANGELOG
**Status:** ✅ COMPLETE
**Date Completed:** January 7, 2026
**Implementation Time:** ~2 hours
## Overview
Implemented the foundational App Setup panel with Identity and SEO sections, allowing users to configure basic app metadata and SEO settings.
---
## Files Created
### 1. Main Panel Component
**File:** `packages/noodl-editor/src/editor/src/views/panels/AppSetupPanel/AppSetupPanel.tsx`
- Main panel container using `BasePanel`
- Listens to ProjectModel metadata changes via `useEventListener`
- Integrates Identity and SEO sections
- Updates handled through ProjectModel's `updateAppConfig()` method
### 2. Identity Section
**File:** `packages/noodl-editor/src/editor/src/views/panels/AppSetupPanel/sections/IdentitySection.tsx`
**Fields:**
- **App Name** - Text input for application name
- **Description** - Multiline textarea for app description
- **Cover Image** - Text input for cover image path
**Features:**
- Clean, labeled inputs with proper spacing
- Uses design tokens for consistent styling
- Inline help text for cover image field
### 3. SEO Section
**File:** `packages/noodl-editor/src/editor/src/views/panels/AppSetupPanel/sections/SEOSection.tsx`
**Fields:**
- **Open Graph Title** - Defaults to App Name if not set
- **Open Graph Description** - Defaults to Description if not set
- **Open Graph Image** - Defaults to Cover Image if not set
- **Favicon** - Path to favicon file (.ico, .png, .svg)
- **Theme Color** - Color picker + hex input for browser theme color
**Features:**
- Smart defaults displayed when fields are empty
- Shows "Defaults to: [value]" hints
- Combined color picker and text input for theme color
- Section has top divider to separate from Identity
---
## Files Modified
### 1. Router Setup
**File:** `packages/noodl-editor/src/editor/src/router.setup.ts`
**Changes:**
- Added import for `AppSetupPanel`
- Registered panel with SidebarModel:
- ID: `app-setup`
- Name: `App Setup`
- Order: 8.5 (between Backend Services and Project Settings)
- Icon: `IconName.Setting`
- Disabled for lessons
---
## Technical Implementation Details
### State Management
- Panel refreshes when `ProjectModel.metadataChanged` event fires with `key === 'appConfig'`
- Uses `useEventListener` hook for proper EventDispatcher integration
- Updates flow through `ProjectModel.instance.updateAppConfig()`
### Smart Defaults
SEO fields show helpful hints when empty:
```
Open Graph Title → Shows: "Defaults to: My App Name"
Open Graph Description → Shows: "Defaults to: App description..."
Open Graph Image → Shows: "Defaults to: /assets/cover.png"
```
These defaults are implemented in ConfigManager (from CONFIG-001) and displayed in the UI.
### Styling Approach
- Inline styles using design tokens (`var(--theme-color-*)`)
- Consistent spacing with `marginBottom: '12px'`
- Label styling matches property panel patterns
- Textarea resizable vertically
### Component Integration
- Uses existing `PropertyPanelTextInput` from core-ui
- Uses `CollapsableSection` for section containers
- Native HTML elements for textarea and color picker
- No custom CSS modules needed for Subtask 1
---
## Usage
### Accessing the Panel
1. Open a project in the editor
2. Look for "App Setup" in the left sidebar
3. Click to open the panel
### Editing Identity
1. Enter app name in "App Name" field
2. Add description in multiline "Description" field
3. Specify cover image path (e.g., `/assets/cover.png`)
### Configuring SEO
1. Optionally override Open Graph title (defaults to app name)
2. Optionally override Open Graph description (defaults to description)
3. Optionally override Open Graph image (defaults to cover image)
4. Set favicon path
5. Choose theme color using picker or enter hex value
### Data Persistence
- All changes save automatically to `project.json` via ProjectModel
- Config stored in `metadata.appConfig`
- Changes trigger metadata change events
---
## Success Criteria - All Met ✅
- [x] App Setup panel appears in sidebar
- [x] Can edit App Name, Description, Cover Image
- [x] SEO fields show smart defaults when empty
- [x] Can override SEO fields
- [x] Theme color has both picker and text input
- [x] All fields save to ProjectModel correctly
- [x] Panel refreshes when config changes
- [x] Uses design tokens for styling
- [x] Proper EventDispatcher integration with useEventListener
---
## Testing Performed
### Manual Testing
1. ✅ Panel appears in sidebar at correct position
2. ✅ Identity fields accept input and save
3. ✅ Textarea allows multiline description
4. ✅ SEO section shows default hints correctly
5. ✅ Entering SEO values overrides defaults
6. ✅ Color picker updates hex input and vice versa
7. ✅ Changes persist after panel close/reopen
8. ✅ No TypeScript or ESLint errors
### Integration Testing
1. ✅ ProjectModel methods called correctly
2. ✅ Metadata change events trigger panel refresh
3. ✅ Config values accessible via `Noodl.Config` at runtime (verified from CONFIG-001)
---
## Known Limitations
1. **No Image Browser** - Cover image, favicon, and OG image use text inputs (file browser to be added later if needed)
2. **No Validation** - Input validation handled by ConfigManager but not shown in UI yet
3. **Limited Theme Color Validation** - No inline validation for hex color format
---
## Next Steps
**Subtask 2: PWA Section**
- Create PWASection component
- Add enable/disable toggle
- Implement PWA configuration fields
- Add app icon picker
- Integrate with CollapsableSection
**Subtask 3: Variables Section**
- Create VariablesSection component
- Implement add/edit/delete variables UI
- Create TypeEditor for different value types
- Add validation and error handling
- Implement category grouping
---
## Code Quality
### Standards Met
- ✅ TypeScript with proper types (no TSFixme)
- ✅ React functional components with hooks
- ✅ useEventListener for EventDispatcher subscriptions
- ✅ Design tokens for all colors
- ✅ Consistent code formatting
- ✅ No console warnings or errors
### Patterns Used
- React hooks: `useState`, `useCallback`, `useEventListener`
- ProjectModel integration via singleton instance
- CollapsableSection for expandable UI sections
- Inline styles with design tokens
