How to convert an HTML String to PDF in Node.JS

Today we are going to use Node.JS to full render a website from HTML and then save it as a PDF file. Our solution has the flexibility to support many advanced features, such as CSS, HTML5, and Javascript. To complete our task in a timely manner, we will forgo manual coding in favor of bringing in an API-based method. Here’s how to do it.

First, install our API client.

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

Second, call our 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.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);

Third, input your HTML string. After that, you will be returned your PDF capture of the website. It’s as easy as that!
