How to lookup domain WHOIS in Javascript

In this article we will be showing step by step how to gather WHOIS information for a domain using Javascript. Total time required, about 5 minutes.

Import our API client first using this script tag, which you can add into your HTML file.

<script src="https://cdn.cloudmersive.com/jsclient/cloudmersive-validate-client.js"></script>

When that’s done with, call this function here:

var CloudmersiveValidateApiClient = require('cloudmersive-validate-api-client');
var defaultClient = CloudmersiveValidateApiClient.ApiClient.instance;
// Configure API key authorization: Apikey
var Apikey = defaultClient.authentications['Apikey'];
Apikey.apiKey = 'YOUR API KEY';
// Uncomment the following line to set a prefix for the API key, e.g. "Token" (defaults to null)
//Apikey.apiKeyPrefix = 'Token';
var apiInstance = new CloudmersiveValidateApiClient.DomainApi();
var domain = "domain_example"; // String | Domain name to check, for example \"cloudmersive.com\".   The input is a string so be sure to enclose it in double-quotes.
var callback = function(error, data, response) {
if (error) {
console.error(error);
} else {
console.log('API called successfully. Returned data: ' + data);
}
};
apiInstance.domainPost(domain, callback);

Enter in your domain and shortly after the API will send back the WHOIS information. It’s really that easy. Want more useful functions like this? We have a ton; everything from swapping document formats to cropping images and converting photos to text.
