Multi-Repo Analysis

## Research: Authentication Patterns in Top 100 GitHub Repos

### Methodology
- Analyzed top 100 starred Node.js projects
- Searched for authentication implementations
- Extracted patterns and libraries used

### Findings

**Most Common Libraries** (n=100):
1. Passport.js - 42%
2. JWT (jsonwebtoken) - 38%
3. Auth0 SDK - 12%
4. Custom implementation - 8%

**Authentication Strategies**:
- Local (username/password): 89%
- OAuth 2.0 (Google/GitHub): 67%
- JWT tokens: 78%
- Session-based: 34%

**Security Patterns**:
- Bcrypt for password hashing: 95%
- HTTPS enforcement: 88%
- Rate limiting: 72%
- CSRF protection: 65%

### Recommendations
Based on analysis, recommend:
1. Use Passport.js for flexibility
2. Implement JWT for stateless auth
3. Add OAuth for social login
4. Use bcrypt (cost factor: 12)

Implementation Discovery

Task: Find how top projects handle file uploads

Search Strategy:
1. GitHub code search: "multer upload"
2. Filter by stars > 1000
3. Analyze implementation patterns

Results:
- Express + Multer: Most common (78%)
- File size limits: Usually 10MB
- Storage: S3 (45%), local disk (35%), GCS (20%)
- Validation: File type checking always present

Competitive Analysis

## Feature Comparison: Real-time Frameworks

| Feature | Socket.IO | WS | uWebSockets |
|---------|-----------|-----|-------------|
| WebSocket | ✅ | ✅ | ✅ |
| Fallbacks | ✅ | ❌ | ❌ |
| Rooms | ✅ | ❌ | ❌ |
| Performance | Medium | High | Highest |
| Use Case | Full-featured | Simple | High-perf |

Recommendation: Socket.IO for most projects
- Built-in reconnection
- Room support
- Proven reliability
