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: 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.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.
