FireCrawl Reference Architecture

Overview

Production-ready architecture patterns for FireCrawl integrations.

Prerequisites

• Understanding of layered architecture

Key Components

Step 1: Client Wrapper

Copy// 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

Copy// 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

Copy// 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

Copy// 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

Error Handling

Examples

Quick Setup Script

Copy# 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
