# Fireflies.ai Reference Architecture

## Overview
Production-ready architecture patterns for Fireflies.ai integrations.

## Prerequisites
- Understanding of layered architecture
- Fireflies.ai SDK knowledge
- TypeScript project setup
- Testing framework configured

## Layer Architecture

```
┌─────────────────────────────────────────┐
│             API Layer                    │
│   (Controllers, Routes, Webhooks)        │
├─────────────────────────────────────────┤
│           Service Layer                  │
│  (Business Logic, Orchestration)         │
├─────────────────────────────────────────┤

├─────────────────────────────────────────┤
│         Infrastructure Layer             │
│    (Cache, Queue, Monitoring)            │
└─────────────────────────────────────────┘
```

## Key Components

### Step 1: Client Wrapper
```typescript
// src/fireflies/client.ts
export class Fireflies.aiService {
  private client: Fireflies.aiClient;
  private cache: Cache;
  private monitor: Monitor;

  constructor(config: Fireflies.aiConfig) {
    this.client = new Fireflies.aiClient(config);
    this.cache = new Cache(config.cacheOptions);
    this.monitor = new Monitor('fireflies');
  }

  async get(id: string): Promise<Resource> {
    return this.cache.getOrFetch(id, () =>
      this.monitor.track('get', () => this.client.get(id))
    );
  }
}
```

### Step 2: Error Boundary
```typescript
// src/fireflies/errors.ts
export class Fireflies.aiServiceError extends Error {
  constructor(
    message: string,
    public readonly code: string,
    public readonly retryable: boolean,
    public readonly originalError?: Error
  ) {
    super(message);
    this.name = 'Fireflies.aiServiceError';
  }
}

export function wrapFireflies.aiError(error: unknown): Fireflies.aiServiceError {
  // Transform SDK errors to application errors
}
```

### Step 3: Health Check
```typescript
// src/fireflies/health.ts
export async function checkFireflies.aiHealth(): Promise<HealthStatus> {
  try {
    const start = Date.now();
    await firefliesClient.ping();
    return {
      status: 'healthy',
      latencyMs: Date.now() - start,
    };
  } catch (error) {
    return { status: 'unhealthy', error: error.message };
  }
}
```

## Configuration Management

```typescript
// config/fireflies.ts
export interface Fireflies.aiConfig {
  apiKey: string;
  environment: 'development' | 'staging' | 'production';
  timeout: number;
  retries: number;
  cache: {
    enabled: boolean;
    ttlSeconds: number;
  };
}

export function loadFireflies.aiConfig(): Fireflies.aiConfig {
  const env = process.env.NODE_ENV || 'development';
  return require(`./fireflies.${env}.json`);
}
```

## Instructions

### Step 1: Create Directory Structure
Set up the project layout following the reference structure above.

### Step 2: Implement Client Wrapper
Create the singleton client with caching and monitoring.

### Step 3: Add Error Handling
Implement custom error classes for Fireflies.ai operations.

### Step 4: Configure Health Checks
Add health check endpoint for Fireflies.ai connectivity.

## Output
- Structured project layout
- Client wrapper with caching
- Error boundary implemented
- Health checks configured

## Error Handling
| Issue | Cause | Solution |
|-------|-------|----------|
| Circular dependencies | Wrong layering | Separate concerns by layer |
| Config not loading | Wrong paths | Verify config file locations |
| Type errors | Missing types | Add Fireflies.ai types |
| Test isolation | Shared state | Use dependency injection |

## Examples

### Quick Setup Script
```bash
# Create reference structure
mkdir -p src/fireflies/{handlers} src/services/fireflies src/api/fireflies
touch src/fireflies/{client,config,types,errors}.ts
touch src/services/fireflies/{index,sync,cache}.ts
```
