How to validate a PDF Document in Node.JS

Since you are here, you probably don’t need me to tell you why PDF validation is important. Instead, you need a quick and easy solution to this problem so you can stop being distracted from more important matters. I’m here to give you just that: PDF document validation in Node.JS in just minutes.

To start, use npm install with this command, allowing setup of our API client.

npm install cloudmersive-convert-api-client --save

Next we will access the following function from the API.

var CloudmersiveConvertApiClient = require('cloudmersive-convert-api-client');
var defaultClient = CloudmersiveConvertApiClient.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 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.validateDocumentPdfValidation(inputFile, callback);

Now if we input a PDF into validateDocumentPdfValidation, you will see that we have already finished. The API will inform us of its validity, or of any errors that interfere with its use. No problem.
