How to validate if a file is executable in Node.JS

Testing if a file is executable can be a tricky business. There is, of course, always the danger of malware threats, and so validation can be used hand-in-hand with virus scanning. On the other side, we obviously don’t want to have files that don’t work. To accomplish this task, we are going to take the easy way out, by employing an API custom designed for it.

If we add this dependency into our package.json, our installation of the API client will begin.

"dependencies": {
"cloudmersive-convert-api-client": "^2.1.6"

With installation complete, we are now able to call our function:

var CloudmersiveConvertApiClient = require('cloudmersive-convert-api-client');var defaultClient = CloudmersiveConvertApiClient.ApiClient.instance;// Configure API key authorization: Apikeyvar 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 CloudmersiveConvertApiClient.ValidateDocumentApi();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.validateDocumentExecutableValidation(inputFile, callback);

Now we just input our file and see what the results are. Easy as that.

There’s an API for that. Cloudmersive is a leader in Highly Scalable Cloud APIs.
