How to Convert HTML-to-PDF with Node

With DocRaptor's unique HTML-to-PDF API, powered by the Prince PDF converter

With DocRaptor, it's fast and painless to convert HTML, CSS, and JavaScript into PDF and XLS documents with Node.

Below are working Node examples for creating documents. Our API reference lists all the generation options and our style and formatting guide will help make it look perfect.

Code Examples

Test API Key:
YOUR_API_KEY_HERE

Not using any of the above languages? It's still easy to use DocRaptor's HTML to PDF API with basic HTTP calls.

Make a POST request

To convert a document, simply send a POST request to https://YOUR_API_KEY_HERE@docraptor.com/docs with the below JSON payload:

{
  "test": true,                                                    // test documents are free but watermarked
  "document_content": "<html><body>Hello</body></html>",           // supply content directly
  // "document_url": "http://docraptor.com/examples/invoice.html", // or use a url
  "type": "pdf",                                                   // pdf or xls or xlsx
  // "javascript": true,                                           // enable JavaScript processing
  // "prince_options": {
  //   "media": "screen"                                           // use screen styles instead of print styles
  //   "baseurl": "http://hello.com"                               // pretend URL when using document_content
  // }
}

For more information, see our complete API reference.

curl

Here's an example of that POST request with curl:

curl http://YOUR_API_KEY_HERE@docraptor.com/docs \
  --fail --silent --show-error \
  --header "Content-Type:application/json" \
  --data '{"test": true,
           "document_url": "http://docraptor.com/examples/invoice.html",
           "type": "pdf" }' > docraptor.pdf

Next Steps

Installation

composer require docraptor/docraptor

Basic Usage

$docraptor = new DocRaptor\DocApi();
$docraptor->getConfig()->setUsername("YOUR_API_KEY_HERE");
// $docraptor->getConfig()->setDebug(true);

$doc = new DocRaptor\Doc();
$doc->setTest(true);                                                   // test documents are free but watermarked
$doc->setDocumentContent("<html><body>Hello World</body></html>");     // supply content directly
// $doc->setDocumentUrl("http://docraptor.com/examples/invoice.html"); // or use a url
$doc->setName("docraptor-php.pdf");                                    // help you find a document later
$doc->setDocumentType("pdf");                                          // pdf or xls or xlsx
// $doc->setJavascript(true);                                          // enable JavaScript processing
// $prince_options = new DocRaptor\PrinceOptions();                    // pdf-specific options
// $doc->setPrinceOptions($prince_options);
// $prince_options->setMedia("screen");                                // use screen styles instead of print styles
// $prince_options->setBaseurl("http://hello.com");                    // pretend URL when using document_content

$create_response = $docraptor->createDoc($doc);

Generating PDFs with Node.js is as easy as making an HTTP request. The Node.js code below is a functional example of a basic PDF creation.

Installation

Install the request module for easy HTTP request management.

$ npm install request

Basic Usage

var request = require('request');
var fs = require('fs');
var content = "<html><body>TEST!</body></html>";

config = {
  url: 'https://docraptor.com/docs',
  encoding: null, //IMPORTANT! This produces a binary body response instead of text
  headers: {
    'Content-Type': 'application/json'
  },
  json: {
    user_credentials: "YOUR_API_KEY_HERE",
    doc: {
      document_content: content,
      type: "pdf",
      test: true,
      // prince_options: {
      //   media:   "screen",          // use screen styles instead of print styles
      //   baseurl: "http://hello.com" // URL to use for generating absolute URLs for assets from relative URLs
      // }
    }
  }
};

request.post(config, function(err, response, body) {
  fs.writeFile('doc_raptor_sample.pdf', body, "binary", function(writeErr) {
    console.log('Saved!');
  });
});

jQuery & JavaScript

The DocRaptor JavaScript library makes it easy to create PDFs with JavaScript. The library does not require jQuery, but you can use jQuery to define your document content. When a PDF is requested, the library constructs a hidden form and submits it to the DocRaptor API. Until all modern browsers support the download link attribute, using this hidden form is the best way to generate a file download directly from JavaScript.

Warning: This code exposes your API key in your website source code. This code should not be used in a publicly-accessible location, instead try using a server-side agent such as PHP or Ruby.

Example Code

<html>
  <head>
    <script src="https://docraptor.com/docraptor-1.0.0.js"></script>
    <script>
      var downloadPDF = function() {
        DocRaptor.createAndDownloadDoc("YOUR_API_KEY_HERE", {
          test: true, // test documents are free, but watermarked
          type: "pdf",
          document_content: document.querySelector('html').innerHTML, // use this page's HTML
          // document_content: "<h1>Hello world!</h1>",               // or supply HTML directly
          // document_url: "http://example.com/your-page",            // or use a URL
          // javascript: true,                                        // enable JavaScript processing
          // prince_options: {
          //   media: "screen",                                       // use screen styles instead of print styles
          // }
        })
      }
    </script>
    <style>
      @media print {
        #pdf-button {
          display: none;
        }
      }
    </style>
  </head>
  <body>
    <h1>Example!</h1>
    <input id="pdf-button" type="button" value="Download PDF" onclick="downloadPDF()" />
  </body>
</html>
We've got a DocRaptor jQuery plugin that you should check out. Examples and usage details can be found on that page.
Note: if you don't want to expose your API key in your client-side JavaScript, check out Referrer-based Document Generation. Also, DocRaptor fully supports the CORS specification, allowing cross-site HTTP requests.
