How to Check Text Input for XSS Attacks in Node.JS

When handling sensitive client data such as contact, location, and other personal information, you need a strategy in place to keep your users protected. Cross-Site Scripting (XSS) attacks account for a large portion of all online security vulnerabilities and pose a serious risk to your users’ information without proper blocks in place. The API shown below will allow you to scan all text input in your site for these XSS attacks. This will help secure your online programs and provide safer interfacing for your client-base.

We will start by installing our SDK:

npm install cloudmersive-validate-api-client --save

You may also add this snippet to your package.json:

"dependencies": {
    "cloudmersive-validate-api-client": "^1.2.4"
  }

Then, we can call our function:

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.TextInputApi();
var value = "value_example"; // String | User-facing text input.
var callback = function(error, data, response) {
  if (error) {
    console.error(error);
  } else {
    console.log('API called successfully. Returned data: ' + data);
  }
};
apiInstance.textInputCheckXss(value, callback);

Now, you can ensure that your users’ information stays secure and provide peace-of mind to your clients. You can retrieve your free API Key from the Cloudmersive website. This will give you access to 800 monthly calls across our library of APIs.
