How to Validate a Last Name in Node.JS

Surname validation will rescue you from a number of different aches and pains, helping with everything from user data collection to weeding out false form submissions. We are not going to be dealing with international name databases or the coding required to make use of them. Instead, we will use an API that’s already set up to do this for us.

Let’s kick things off with the API client’s installation via this reference for your package.json.

"dependencies": {
    "cloudmersive-validate-api-client": "^1.1.4"
  }

Call nameValidateLastName next.

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.NameApi();
var input = new CloudmersiveValidateApiClient.LastNameValidationRequest(); // LastNameValidationRequest | Validation request information
var callback = function(error, data, response) {
if (error) {
console.error(error);
} else {
console.log('API called successfully. Returned data: ' + data);
}
};
apiInstance.nameValidateLastName(input, callback);

And that’s all she wrote. Yup, it’s just that easy.
