How to get PDF Metadata in Node.JS

On today’s agenda, extracting metadata from PDFs! Yeah, I know, it’s not very exciting. But do you know what is an exciting thought? We will be done in less than 5 minutes. Doesn’t seem so bad now, does it? Let’s get started.

With this command, we can import our client data via npm install.

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

Next we call editPdfGetMetadata:

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.EditPdfApi();
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.editPdfGetMetadata(inputFile, callback);

And finally… we’re done! Yup, it’s really that easy. Consider your metadata as good as harvested.
