🔍 DomainSearcher

DomainSearcher is a domain status checker.

Motivation

Most of time we need to browser and some shitty hosting firm's domain search page to check availabity domain. I think its aproxmatically takes 10-15 seconds to check single domain, DomainSearcher package takes 1.5s to query including 15 domain extension.

Highlights

• Returns domains status
• Requires zero config, but configurable when needed
• Recognises queries and responses
• Uses WHOIS servers from IANA, if not provided
• Discover all available TLDs

→ See it in action here https://dmns.app

Getting Started

Installation

npm i @zaferatli/domainchecker -g

Usage

From terminal:

domainSearch google.com --disableCachedWhoisServers=false

From JS module:

const domainsearcher = require('@zaferatli/domainchecker')

const domainInfo = domainsearcher.search('google.com')

→ See all examples

Domain whois

Get WHOIS info for domains.

domainsearcher.search(domain, options): Promise<Object<whoisServer>>

• domain - Domain name, excluding any subdomain. Ex: 'google.com'
• options - Object of options to use, all optional:
  • hideLogs - Hide all console include table log.
  • disableCachedWhoisServers - We cache most used 15 TLDs whoisServer, when set true its get from whois.iana.org
  • hideSuggestedDomains - When query domain we add 15 more domain extension to check, when set true its get only you queried
  • showWhoisQuery - Return whoisQuery result as well, responseFields can be modified according this result.
  • responseFields - Response could be modified with "Last update of whois database,status,created,expiry"
  • suggestedDomainArray - Can be specify auto suggested domain with com,net,org

const domainsearcher = require('@zaferatli/domainchecker')

;(async () => {
    const domainName = 'google.com'

    const domainWhois = await domainsearcher.search(domainName)

    console.log(domainWhois)
})()

Returns a promise which resolves with an Object of WHOIS servers checked:

This may not work correctly because i coded :/

Unsupported TLDs

• .ch - WHOIS server for .ch doesn't return WHOIS info, works only in browser https://www.nic.ch/whois/. This library can be used only to check .ch domain availability, example here https://runkit.com/andreiigna/5efdeaa8e4f2d8001a00312d
