RDAPify - Unified, Secure, High-Performance RDAP Client for Enterprise Applications

🎉 LATEST RELEASE: v0.1.2 — Production-ready with interactive playground, advanced features including authentication, proxy support, compression, retry strategies, and comprehensive monitoring. See What's New in v0.1.2 below.

RDAPify unifies RDAP queries across all global registries (Verisign, ARIN, RIPE, APNIC, LACNIC) with robust security protection, exceptional performance, and an integrated developer experience. This isn't just another RDAP client — it's a complete platform for processing registration data securely.

Note: This project eliminates the need for traditional WHOIS protocol, while maintaining backward compatibility when needed.

🚀 Why RDAPify?

Direct RDAP queries are complex — each registry uses different formats, rate limits, and security procedures. Instead of reinventing the wheel for every project:

- Maintaining multiple WHOIS/RDAP implementations
- Manually handling registry differences
- Constant worry about SSRF vulnerabilities
- Unpredictable performance without caching
+ One unified solution, rigorously tested, production-ready

RDAPify intelligently addresses these challenges:

• ✅ Data Normalization: Consistent response regardless of source registry
• ✅ SSRF Protection: Prevent attacks on internal infrastructure
• ✅ Exceptional Performance: Smart caching, parallel processing, memory optimization
• ✅ Node.js Compatibility: Verified working on Node.js (target: 16+; Bun, Deno, Cloudflare Workers: untested)
• ✅ GDPR-ready: Built-in tools for automatically redacting personal data

📦 Quick Installation

# Using npm
npm install rdapify

# Using yarn
yarn add rdapify

# Using pnpm
pnpm add rdapify

Experimental (untested):

# Using Bun (untested)
bun add rdapify

⚡ Get Started in 30 Seconds

Basic Usage

import { RDAPClient } from 'rdapify';

// Create a client with default settings
const client = new RDAPClient();

// Query a domain
const result = await client.domain('example.com');

console.log({
  domain: result.query,
  registrar: result.registrar?.name,
  status: result.status,
  nameservers: result.nameservers,
  created: result.events.find((e) => e.type === 'created')?.date,
  expires: result.events.find((e) => e.type === 'expiration')?.date,
});

With Security & Performance Options

import { RDAPClient } from 'rdapify';

// Create a secure client with optimized defaults
const client = new RDAPClient({
  cache: true, // Automatic caching (1 hour TTL)
  redactPII: true, // Automatically redact personal information
  retry: {
    // Smart retries for transient failures
    maxAttempts: 3,
    backoff: 'exponential',
  },
});

// Query domain, IP, or ASN
const domain = await client.domain('example.com');
const ip = await client.ip('8.8.8.8');
const asn = await client.asn('AS15169');

Example Output:

{
  "domain": "example.com",
  "registrar": "Internet Assigned Numbers Authority",
  "status": ["clientDeleteProhibited", "clientTransferProhibited", "clientUpdateProhibited"],
  "nameservers": ["a.iana-servers.net", "b.iana-servers.net"],
  "created": "1995-08-14T04:00:00Z",
  "expires": "2026-08-13T04:00:00Z"
}

With Monitoring & Metrics (v0.1.2+)

import { RDAPClient } from 'rdapify';

// Create client with monitoring enabled
const client = new RDAPClient({
  cache: true,
  logging: {
    level: 'info', // debug, info, warn, error
    enabled: true,
  },
});

// Perform queries
await client.domain('example.com');
await client.ip('8.8.8.8');

// Get performance metrics
const metrics = client.getMetrics();
console.log(`Success Rate: ${metrics.successRate}%`);
console.log(`Avg Response Time: ${metrics.avgResponseTime}ms`);
console.log(`Cache Hit Rate: ${metrics.cacheHitRate}%`);

// Get connection pool statistics
const poolStats = client.getConnectionPoolStats();
console.log(`Active Connections: ${poolStats.activeConnections}`);

// Get recent logs
const logs = client.getLogs(10);
logs.forEach((log) => {
  console.log(`[${log.level}] ${log.message}`);
});

// Clean up resources
client.destroy();

With Authentication & Proxy (v0.1.3+)

import { RDAPClient, AuthenticationManager, ProxyManager } from 'rdapify';

// Setup authentication
const auth = new AuthenticationManager({
  type: 'bearer', // 'basic' | 'bearer' | 'apiKey' | 'oauth2'
  token: 'your-api-token',
});

// Setup proxy
const proxy = new ProxyManager({
  host: 'proxy.example.com',
  port: 8080,
  protocol: 'http', // 'http' | 'https' | 'socks4' | 'socks5'
  auth: {
    username: 'proxyuser',
    password: 'proxypass',
  },
});

// Add bypass patterns
proxy.addBypass('*.internal.com');

// Use in your HTTP client configuration
const headers = auth.getAuthHeaders();
const proxyUrl = proxy.shouldBypass('example.com')
  ? undefined
  : proxy.getProxyUrl();

With Advanced Features (v0.1.3+)

import {
  RDAPClient,
  RetryStrategy,
  QueryPriorityQueue,
  PersistentCache,
  CompressionManager,
} from 'rdapify';

// Setup retry strategy with circuit breaker
const retry = new RetryStrategy({
  strategy: 'exponential-jitter',
  maxAttempts: 5,
  circuitBreaker: {
    enabled: true,
    threshold: 3,
    timeout: 60000,
  },
});

// Setup priority queue
const queue = new QueryPriorityQueue(5, async (domain) => {
  return await client.domain(domain);
});

// Enqueue with priority
await queue.enqueue('critical.com', 'high');
await queue.enqueue('normal.com', 'normal');
await queue.enqueue('background.com', 'low');

// Setup persistent cache
const cache = new PersistentCache({
  storage: 'file',
  path: './cache/rdap-cache.json',
  ttl: 3600000, // 1 hour
  autoSave: true,
});

// Setup compression
const compression = new CompressionManager({
  enabled: true,
  types: ['br', 'gzip', 'deflate'],
});

🛡️ Security as a Core Principle

We don't treat security as an add-on feature — it's fundamental to our design. RDAPify protects your applications from:

| Threat | Protection Mechanism | Criticality | | -------------- | ---------------------------------------- | ------------ | | SSRF | Domain validation, blocking internal IPs | 🔴 Critical | | DoS | Rate limiting, timeouts | 🟠 Important | | Data Leaks | PII redaction, no raw response storage | 🔴 Critical | | MitM | Mandatory HTTPS, certificate validation | 🟠 Important | | Data Injection | Schema validation, strict parsing | 🟠 Important |

Read our Security Whitepaper for deeper technical details and advanced scenarios.

Key Design Principles

1. Modular Architecture: Each file has a single, clear responsibility
2. Small Files: All files <250 LOC for easy maintenance
3. Type Safety: Strict TypeScript with explicit types throughout
4. Testability: 146 tests with >90% coverage
5. Security First: SSRF protection and PII redaction built-in
6. Performance: Smart caching and optimized parsing

Recent Improvements (Phase 2 Refactoring)

• ✅ Extracted QueryOrchestrator from RDAPClient (-29% LOC)
• ✅ Split validators into focused modules (-87% in main file)
• ✅ Split helpers into focused modules (-80% in main file)
• ✅ Split types into enums, entities, responses (-87% in main file)
• ✅ 712 lines of duplication eliminated
• ✅ 100% backward compatible (re-export shims)

See REFACTOR_STATUS.md for detailed refactoring progress.

📋 Roadmap to v0.2.0 (Continued)

🔍 Version Verification

RDAPify intentionally does not export ./package.json in the package exports for security and API surface minimization. Attempting to import it will throw an expected error:

// ❌ This will throw ERR_PACKAGE_PATH_NOT_EXPORTED (expected behavior)
const pkg = require('rdapify/package.json');
// Error: Package subpath './package.json' is not defined by "exports"

Safe Version Verification Methods

Method 1: Using npm (recommended)

npm ls rdapify
# Output: [email protected]

Method 2: Programmatic check via require.resolve

const fs = require('fs');
const path = require('path');

const entry = require.resolve('rdapify');
const pkgPath = path.join(path.dirname(entry), '..', 'package.json');
const version = JSON.parse(fs.readFileSync(pkgPath, 'utf8')).version;

console.log('rdapify version:', version);
// Output: 0.1.0

Method 3: Check installed version in package.json

cat node_modules/rdapify/package.json | grep version

This design decision prevents accidental exposure of internal package metadata and maintains a minimal public API surface.
