# architecture-documentation-generator

Comprehensive architecture documentation generator that synthesizes all analysis into complete project documentation with diagrams, guides, and implementation plans.

## Usage

Ask me to generate architecture documentation. I'll synthesize all analyses, create diagrams, and produce comprehensive guides for developers, operators, and stakeholders.

## Documentation Workflow

### Phase 1: Information Gathering

```javascript
const infoGathering = {
  // Collect from specialists
  analyses: {
    codebase: getCodebaseExplorerOutput(),
    frontend: getFrontendAnalystOutput(),
    configuration: getConfigurationAnalystOutput(),
    api: getAPIDocumenterOutput(),
    database: getDatabaseArchitectOutput(),
  },

  // Synthesize insights
  synthesis: {
    patterns: extractArchitecturalPatterns(),
    decisions: extractDesignDecisions(),
    tradeoffs: extractTradeoffs(),
    rationale: extractRationale(),
  },

  // Identify audiences
  audiences: {
    developers: identifyDevAudience(),
    operators: identifyOpsAudience(),
    architects: identifyArchAudience(),
    stakeholders: identifyStakeholders(),
  },
};
```

### Phase 2: Documentation Generation

```javascript
const docGeneration = {
  // Core documentation
  core: {
    overview: generateOverview(),
    quickstart: generateQuickstart(),
    architecture: generateArchitectureDoc(),
    patterns: generatePatternsDoc(),
    decisions: generateADRs(), // Architecture Decision Records
  },

  // Technical documentation
  technical: {
    api: generateAPIDoc(),
    database: generateDatabaseDoc(),
    deployment: generateDeploymentDoc(),
    security: generateSecurityDoc(),
    testing: generateTestingDoc(),
  },

  // Operational documentation
  operational: {
    setup: generateSetupGuide(),
    runbook: generateRunbook(),
    monitoring: generateMonitoringGuide(),
    troubleshooting: generateTroubleshooting(),
    maintenance: generateMaintenanceGuide(),
  },
};
```

### Phase 3: Diagram Generation

```javascript
const diagramGeneration = {
  // System diagrams
  system: {
    context: generateC4Context(),
    container: generateC4Container(),
    component: generateC4Component(),
    deployment: generateDeploymentDiagram(),
  },

  // Flow diagrams
  flows: {
    authentication: generateAuthFlow(),
    payment: generatePaymentFlow(),
    booking: generateBookingFlow(),
    navigation: generateNavigationFlow(),
  },

  // Data diagrams
  data: {
    erd: generateERDiagram(),
    dataFlow: generateDataFlowDiagram(),
    stateTransition: generateStateDiagram(),
  },
};
```

### Phase 4: Guide Generation

```javascript
const guideGeneration = {
  // Developer guides
  developer: {
    gettingStarted: generateGettingStarted(),
    contributing: generateContributing(),
    codingStandards: generateCodingStandards(),
    testing: generateTestingGuide(),
    debugging: generateDebuggingGuide(),
  },

  // Feature guides
  features: {
    addingPages: generatePageGuide(),
    addingAPIs: generateAPIGuide(),
    i18n: generateI18nGuide(),
    authentication: generateAuthGuide(),
    payment: generatePaymentGuide(),
  },

  // Operational guides
  operations: {
    deployment: generateDeploymentGuide(),
    monitoring: generateMonitoringGuide(),
    backup: generateBackupGuide(),
    disaster: generateDisasterRecovery(),
    scaling: generateScalingGuide(),
  },
};
```

# System Architecture

## Overview

Mawidi is a modern, server-first Next.js application built for the GCC market with comprehensive bilingual support.

## Architecture Principles

1. **Server-First**: Leverage Next.js server components for performance
2. **Type-Safe**: End-to-end TypeScript with strict mode
3. **Secure by Design**: Multi-layered security with rate limiting, CSRF, OTP
4. **Internationally Ready**: Native RTL/LTR support, modular translations
5. **Production-Ready**: Docker-optimized, monitoring-ready, scalable

        subgraph "Application Tier"
            App1[Next.js Instance 1]
            App2[Next.js Instance 2]

    App1 -->|API Calls| Stripe
    App1 -->|Messages| WhatsApp

    User -->|Static Assets| CDN
    CDN -->|Cache Miss| App1
```

## Security Architecture

### Layers of Security

1. **Network Layer**
   - HTTPS only (TLS 1.3)
   - CORS configured
   - Rate limiting (Upstash Redis)

2. **Application Layer**
   - CSRF protection (token-based)
   - XSS prevention (DOMPurify)
   - SQL injection prevention (Prisma ORM)
   - Input validation (Zod + validator.js)

3. **Authentication Layer**
   - JWT sessions (2-hour expiry)
   - OTP verification (email-based)
   - Account lockout (5 failed attempts)
   - Password hashing (bcrypt, 12 rounds)

4. **Authorization Layer**
   - Role-based access control
   - Resource-level permissions
   - Audit logging (Prisma)

5. **Data Layer**
   - Encrypted connections
   - Secrets management
   - Regular backups
   - Data anonymization (PII)

## Scalability Considerations

### Current Capacity

- Single instance handles: ~1000 concurrent users
- Database: Handles ~10,000 queries/second
- Redis: Handles ~100,000 requests/second

### Scaling Strategy

#### Horizontal Scaling (Recommended)

```
Load Balancer → [App Instance 1, App Instance 2, ..., App Instance N]
                        ↓
                  [PostgreSQL Primary + Replicas]
                        ↓
                     [Redis]
```

Benefits:

- No single point of failure
- Linear performance scaling
- Easy to add/remove instances

#### Vertical Scaling (Short-term)

- Increase instance resources
- Optimize database queries
- Implement caching strategies

### Performance Targets

- Page load: <2 seconds
- API response: <200ms (p95)
- Database query: <50ms (p95)
- Uptime: 99.9% (SLA)

## Monitoring & Observability

### Metrics to Track

- **Performance**: Response times, throughput, error rates
- **Resources**: CPU, memory, disk, network usage
- **Business**: Bookings, revenue, user activity
- **Security**: Failed logins, rate limit hits, suspicious activity

### Recommended Tools

- **APM**: Sentry / New Relic / Datadog
- **Logs**: CloudWatch / LogTail / Better Stack
- **Uptime**: UptimeRobot / Pingdom
- **Analytics**: Vercel Analytics / Google Analytics

## Disaster Recovery

### Backup Strategy

- **Database**: Daily full backup + hourly incremental
- **Static assets**: Replicated across CDN
- **Configuration**: Version controlled in Git
- **Secrets**: Stored in secrets manager

### Recovery Procedures

- **RTO** (Recovery Time Objective): 1 hour
- **RPO** (Recovery Point Objective): 1 hour
- **Failover**: Automatic to standby instance
- **Data Recovery**: Restore from latest backup

## Future Architecture Considerations

### Phase 2 (6-12 months)

- Microservices extraction (booking, payment, notification)
- Event-driven architecture (Kafka / RabbitMQ)
- GraphQL API (Apollo Server)
- Mobile apps (React Native)

### Phase 3 (12-24 months)

- Multi-region deployment
- Advanced analytics (Machine Learning)
- Real-time collaboration features
- White-label solutions

```
