How to convert HTML to PDF in Node.js

To start, first we need to add a reference in package.json:

"dependencies": {
    "cloudmersive-convert-api-client": "^1.2.7"
  }

Now, we need to load the package with a require:

var CloudmersiveConvertApiClient = require('cloudmersive-convert-api-client');

Finally, we just call the convertWebHtmlToPdf function which will take an HTML string as input, and return a PDF as the result:

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';
var apiInstance = new CloudmersiveConvertApiClient.ConvertWebApi();
var input = new CloudmersiveConvertApiClient.HtmlToPdfRequest(); // HtmlToPdfRequest | HTML to PDF request parameters
var callback = function(error, data, response) {
  if (error) {
    console.error(error);
  } else {
    console.log('API called successfully. Returned data: ' + data);
  }
};
apiInstance.convertWebHtmlToPdf(input, callback);

Simply fill in the appropriate field in the input parameter above an input string containing valid HTML. Images can also be included (absolute URLs are recommended).

It’s that easy!
