## ✅ App 1: react-capacitor (Frontend Example)

### Before
```
src/
├── components/
│   ├── LiveUpdateDemo.tsx
│   ├── AppUpdateDemo.tsx
│   ├── AppReviewDemo.tsx
│   ├── AdvancedFeatures.tsx
│   ├── SecurityDemo.tsx
│   └── AnalyticsDemo.tsx
├── context/
│   └── UpdateContext.tsx
├── App.tsx (complex with tabs)
├── main.tsx
└── index.css
```

**Issues:**
- 6 separate demo components
- Context provider for state management
- Tab navigation system
- Complex UI with multiple features
- 9+ files in src/

### After
```
src/
├── App.tsx       # 135 lines - all demo logic
├── App.css       # Clean gradient design
└── main.tsx      # Entry point
```

**Changes Made:**
1. ✅ Consolidated to single App.tsx component
2. ✅ Simple useState for status tracking
3. ✅ Clear "change this text and deploy" demo section
4. ✅ Removed all complex components (6 files deleted)
5. ✅ Removed UpdateContext provider
6. ✅ Created simple, gradient CSS
7. ✅ Comprehensive README with quick start guide

**Result:**
- **3 files** in src/ (down from 9)
- **67% reduction** in file count
- **Simple and focused** - demonstrates OTA updates only
- **Easy to understand** in 5 minutes

## ✅ App 2: node-express (Backend Example)

### Before
```
src/
├── index.js (complex with middleware)
├── routes/
│   ├── auth.js
│   ├── updates.js
│   ├── bundles.js
│   ├── analytics.js
│   └── health.js
├── middleware/
│   ├── error.js
│   ├── logging.js
│   └── validation.js
├── database/
│   └── init.js
└── utils/
    └── logger.js
scripts/
├── init-db.js
└── migrate.js
```

**Dependencies (Before):** 15+ packages
- express, cors, helmet, compression
- express-rate-limit, winston
- sqlite3, better-sqlite3
- joi, bcryptjs, jsonwebtoken
- nanoid, archiver, crypto, semver, dotenv

**Issues:**
- Production-ready features (too complex)
- SQLite database with migrations
- Complex authentication (JWT, bcrypt)
- Separate route files for everything
- Advanced logging with Winston
- Rate limiting, compression, helmet

### After
```
node-express/
├── index.js          # 150 lines - all server logic
├── bundles/          # Auto-created for file storage
├── metadata.json     # Auto-created for bundle metadata
├── package.json      # Only 3 dependencies
├── .env.example      # Simple config
└── README.md         # Comprehensive guide
```

**Dependencies (After):** 3 packages only
- express
- cors
- multer

**Changes Made:**
1. ✅ Single index.js file with all routes
2. ✅ File-based storage (no database!)
3. ✅ JSON file for metadata
4. ✅ Removed all complex middleware
5. ✅ Removed authentication (simple demo)
6. ✅ Removed rate limiting, helmet, compression
7. ✅ Removed Winston logging (console.log)
8. ✅ Removed src/ and scripts/ directories
9. ✅ Created simple .env.example
10. ✅ Comprehensive README with curl examples

**Result:**
- **87% fewer dependencies** (15+ → 3)
- **Single file** server implementation
- **File-based storage** - no database setup needed
- **4 essential endpoints** only
- **Perfect for local testing**

├── index.ts (complex with scheduled functions)
├── routes/
│   ├── updates.ts
│   ├── bundles.ts
│   └── analytics.ts
├── middleware/
│   └── auth.ts
└── utils/
    ├── validation.ts
    └── version.ts
```

**Dependencies (Before):** 8 packages
- cors, express
- firebase-admin, firebase-functions
- jsonwebtoken, multer, uuid

**Issues:**
- Separate route files
- Complex auth middleware
- Scheduled cleanup functions
- Advanced validation
- Too many features for demo

### After
```
firebase-backend/
├── src/
│   └── index.ts          # 143 lines - single Cloud Function
├── firebase.json
├── firestore.rules        # Simplified
├── firestore.indexes.json
├── storage.rules          # Simplified
├── package.json           # 5 dependencies
├── tsconfig.json
└── README.md              # Comprehensive guide
```

**Dependencies (After):** 5 packages
- cors, express
- firebase-admin, firebase-functions
- multer

**Changes Made:**
1. ✅ Consolidated to single index.ts file
2. ✅ Removed separate route files
3. ✅ Removed auth middleware (simple demo)
4. ✅ Removed scheduled functions
5. ✅ Removed utils/ directory
6. ✅ Simplified Firestore rules (public read, auth write)
7. ✅ Simplified Storage rules
8. ✅ Comprehensive README with Firebase setup
9. ✅ Updated package.json scripts

**Result:**
- **Single Cloud Function file** (143 lines)
- **60% simpler** codebase
- **3 essential endpoints** only
- **Firestore + Storage integration**
- **Serverless and auto-scaling**
