txPDF

Check out the article Webpage to PDF Microservice for a quick getting started guide.

txPDF is an HTML to PDF microservice by txn2. txPDF is built on top of the n2pdf container exposing an API endpoint that returns a PDF document from web based POST request.

Example Post Body:

{
  "options": {
    "print_media_type": true
  },
  "pages": [
    {
      "Location": "https://www.example.com"
    }
  ]
}

If you want to convert web pages to PDF but do not need a web service you can use the n2pdf container directly as a command line tool.

Security

txPDF is intended as a backend service and should only be accessible by other trusted services. txPDF allows the passing of template directives that can access environment or request data. This is useful and make txPDF highly flexible. However please treat txPDF as a remote code executor and implement it accordingly. See #2 for more on this issue.

Docker Use

Run the txPDF Docker container on your local workstation for testing. Forward port 8080 or any free port to txPDFs default service port 8080 on the container.
