How to Convert Keynote KEY to PNG in Node.JS

File format conversion becomes exponentially more necessary when moving between operating systems, but also becomes much more difficult as well. For Node.JS users, I have a nice solution in mind. A solution that will eliminate the need for wrecking your afternoon with coding this out yourself. This will use a Cloudmersive API, which will trivialize the task, as well as many more.

First step: add the client to your package.json file:

"dependencies": {
    "cloudmersive-convert-api-client": "^2.4.8"
  }

Second step: call the function:

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.ConvertDocumentApi();
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.convertDocumentKeynoteToPng(inputFile, callback);

And that’s really all there is to it.
