rdapper is a Node library that performs domain registration lookups and returns the results in a consistent structure.
It uses RDAP as its primary source of registration data and falls back to WHOIS when needed, making it useful for applications that need normalized domain ownership, registrar, status, and date information.
This is free and open source software.
Key Features
- Performs RDAP-first lookups using IANA bootstrap data, with automatic WHOIS fallback when RDAP data isn’t available.
- Returns normalized records containing details such as registrar information, contacts, nameservers, EPP statuses, important dates, DNSSEC status, privacy flag, and source metadata.
- Includes helper functions to convert a domain or URL to its registrable domain and to quickly test whether a domain is registered or available.
- Provides a minimal command line interface for quick checks from a terminal or standard input.
- Ships with TypeScript types and is designed as an ESM-only package for modern JavaScript and TypeScript projects.
- Supports custom caching of IANA RDAP bootstrap data to reduce repeated network requests in production workloads.
