How to lookup domain WHOIS in Node.js?

First, we need to add a package.json reference to the library:

"dependencies": {
"cloudmersive-validate-api-client": "^1.1.2"
}

Next, we need to import the library:

var CloudmersiveValidateApiClient = require('cloudmersive-validate-api-client');

Now all we need to do is call the domainPost method:

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';
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);

That’s it — we will get back a result for yahoo.com, such as:
