How to virus scan a RAR archive in Javascript

Every single day, new cyber threats claw their way through the ether toward your helpless system. To really feel secure in the internet age, you are going to need some proper virus scanning to protect yourself. This post shows a quick step by step of how to set this up in a tiny fraction of the normal time required by using an API. Let’s dive in.

We shall use the following script tag in our HTML file to import the virus scan client that we will be implementing.

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

Now call our desired function, like so.

var CloudmersiveVirusApiClient = require('cloudmersive-virus-api-client');
var defaultClient = CloudmersiveVirusApiClient.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 CloudmersiveVirusApiClient.ScanApi();
var inputFile = "/path/to/file"; // File | Input file to perform the operation on.
var callback = function(error, data, response) {
if (error) {
console.error(error);
} else {
console.log('API called successfully. Returned data: ' + data);
}
};
apiInstance.scanFile(inputFile, callback);

And just like that, we are already finished. After being called, the API will scan the inputFile for 17 million plus virus and malware definitions. This list gets updated constantly to respond to new threats.
