Implement FireCrawl reference architecture with best-practice project layout. Use when designing new FireCrawl integrations, reviewing project structure, or establishing architecture standards for FireCrawl applications. Trigger with phrases like "firecrawl architecture", "firecrawl best practices", "firecrawl project structure", "how to organize firecrawl", "firecrawl layout".

Key Components

Step 1: Client Wrapper

// src/firecrawl/client.ts
export class FireCrawlService {
  private client: FireCrawlClient;
  private cache: Cache;
  private monitor: Monitor;

  constructor(config: FireCrawlConfig) {
    this.client = new FireCrawlClient(config);
    this.cache = new Cache(config.cacheOptions);
    this.monitor = new Monitor('firecrawl');
  }

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

Step 2: Error Boundary

// src/firecrawl/errors.ts
export class FireCrawlServiceError extends Error {
  constructor(
    message: string,
    public readonly code: string,
    public readonly retryable: boolean,
    public readonly originalError?: Error
  ) {
    super(message);
    this.name = 'FireCrawlServiceError';
  }
}

export function wrapFireCrawlError(error: unknown): FireCrawlServiceError {
  // Transform SDK errors to application errors
}

Step 3: Health Check

// src/firecrawl/health.ts
export async function checkFireCrawlHealth(): Promise<HealthStatus> {
  try {
    const start = Date.now();
    await firecrawlClient.ping();
    return {
      status: 'healthy',
      latencyMs: Date.now() - start,
    };
  } catch (error) {
    return { status: 'unhealthy', error: error.message };
  }
}

Configuration Management

// config/firecrawl.ts
export interface FireCrawlConfig {
  apiKey: string;
  environment: 'development' | 'staging' | 'production';
  timeout: number;
  retries: number;
  cache: {
    enabled: boolean;
    ttlSeconds: number;
  };
}

export function loadFireCrawlConfig(): FireCrawlConfig {
  const env = process.env.NODE_ENV || 'development';
  return require(`./firecrawl.${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 FireCrawl operations.

Step 4: Configure Health Checks

Add health check endpoint for FireCrawl connectivity.

Output

  • Structured project layout
  • Client wrapper with caching
  • Error boundary implemented
  • Health checks configured

Examples

Quick Setup Script

# Create reference structure
mkdir -p src/firecrawl/{handlers} src/services/firecrawl src/api/firecrawl
touch src/firecrawl/{client,config,types,errors}.ts
touch src/services/firecrawl/{index,sync,cache}.ts
