# CONFIG-002 Subtask 2: PWA Section - Changelog

**Status**: ✅ Complete  
**Completed**: 2026-01-07

## Objective

Add Progressive Web App (PWA) configuration section to the App Setup Panel.

## Changes Made

### New Files Created

#### 1. PWASection Component

**File**: `packages/noodl-editor/src/editor/src/views/panels/AppSetupPanel/sections/PWASection.tsx`

**Features**:

- **Enable/Disable Toggle** - Master switch for PWA functionality
- **Conditional Rendering** - Fields only appear when PWA is enabled
- **Smart Defaults** - Automatically provides sensible defaults on enable

**Fields**:

1. **Enable PWA** - Checkbox toggle
2. **Short Name** - App name for home screen (12 chars recommended)
3. **Start URL** - Where the PWA launches (default: `/`)
4. **Display Mode** - Dropdown with 4 options:
   - Standalone (Recommended)
   - Fullscreen
   - Minimal UI
   - Browser
5. **Background Color** - Color picker for splash screen
6. **Source Icon** - Path to 512x512 icon (auto-generates all sizes)

**UX Improvements**:

- Help text for each field
- Disabled state when PWA not enabled
- Color picker with hex input synchronization
- Defaults applied automatically on enable

### Modified Files

#### 1. AppSetupPanel.tsx

**Changes**:

- Imported `PWASection` component
- Added `updatePWA` callback with proper type handling
- Integrated PWASection after SEOSection
- Handles undefined PWA config gracefully

**Code Pattern**:

```typescript
const updatePWA = useCallback((updates: Partial<NonNullable<typeof config.pwa>>) => {
  const currentConfig = ProjectModel.instance.getAppConfig();
  ProjectModel.instance.updateAppConfig({
    pwa: { ...(currentConfig.pwa || {}), ...updates } as NonNullable<typeof config.pwa>
  });
}, []);
```

## Technical Decisions

### Enable/Disable Pattern

When enabled, automatically sets defaults:

```typescript
{
  enabled: true,
  startUrl: '/',
  display: 'standalone'
}
```

### Display Mode Options

Used `as const` for type safety:

```typescript
const DISPLAY_MODES = [
  { value: 'standalone', label: 'Standalone (Recommended)' },
  ...
] as const;
```

### Optional PWA Config

PWA is optional in AppConfig, so component handles `undefined`:

```typescript
pwa: AppPWA | undefined;
```

## Testing Checklist
