|---|---|
| express | A library for building web applications and APIs. |
| app | The Express application instance. |
| port | The port the server listens on, either from the environment variable or defaulting to 3003. |
| getTldInfo | Function that returns an array of TLDs of the specified type. |
| getDnsServers | Function that returns an array of DNS servers of the specified type. |
| mockDomainAvailability | Function that returns a random boolean value to simulate domain availability. |
| fetchHnsDomainData | Function that returns an object containing data related to an HNS domain. |
This server is built using the Express library and provides various API endpoints for getting TLD information, DNS server information, domain availability, and HNS domain data. The server listens on a specified port, either from the environment variable PORT or defaulting to 3003.
The server imports various functions from other modules, such as getTldInfo, getDnsServers, mockDomainAvailability, and fetchHnsDomainData. These functions are used to handle specific API requests.
The available API endpoints are:
/api/tld/:tldType: Get TLDs of the specified type (HNS or ICANN)./api/dns/:dnsType: Get DNS servers of the specified type (HNS or ICANN)./api/domain/availability: Get domain availability for both ICANN and HNS./api/hns/domain/:name: Get HNS domain data for the specified name.
The server starts listening on the specified port and logs various example API URLs to the console.
