Installation

pip install gotenberg-client

What

This is a Python client for interfacing with Gotenberg, which in turn is a wrapper around powerful tools for PDF generation and creation in various ways, using a stateless API. It's a very powerful tool to generate and manipulate PDFs.

Why

As far as I can tell, no active Python library exists to interface with the Gotenberg API.

Features

• HTTP/2 enabled by default
• Abstract away the handling of multi-part/form-data and deal with Paths instead
• Based on the modern httpx library
• Full support for type hinting and concrete return types as much as possible
• Nearly full test coverage run against an actual Gotenberg server for multiple Python and PyPy versions

How

All the routes and options from the Gotenberg routes are implemented, with the exception of the Prometheus metrics endpoint. All the routes use the same format and general idea.

1. First, you add the file or files you want to process
2. Then, configure the endpoint with its various options the route supports
3. Finally, run the route and receive your resulting file

• Files will be PDF or ZIP, depending on what endpoint and its configuration. Endpoints which handle multiple files, but don't merge them, return a ZIP archive of the resulting PDFs

Examples

Converting a single HTML file into a PDF:

from gotenberg_client import GotenbergClient

with GotenbergClient("http://localhost:3000") as client:
    with client.chromium.html_to_pdf() as route:
      response = route.index("my-index.html").run()
      Path("my-index.pdf").write_bytes(response.content)

Converting an HTML file with additional resources into a PDF:

from gotenberg_client import GotenbergClient

with GotenbergClient("http://localhost:3000") as client:
    with client.chromium.html_to_pdf() as route:
      response = route.index("my-index.html").resource("image.png").resource("style.css").run()
      Path("my-index.pdf").write_bytes(response.content)

Converting an HTML file with additional resources into a PDF/A1a format:

from gotenberg_client import GotenbergClient
from gotenberg_client.options import PdfAFormat

with GotenbergClient("http://localhost:3000") as client:
    with client.chromium.html_to_pdf() as route:
      response = route.index("my-index.html").resources(["image.png", "style.css"]).pdf_format(PdfAFormat.A1a).run()
      Path("my-index.pdf").write_bytes(response.content)

Converting a URL into PDF, in landscape format

from gotenberg_client import GotenbergClient
from gotenberg_client.options import PageOrientation

with GotenbergClient("http://localhost:3000") as client:
    with client.chromium.url_to_pdf() as route:
      response = route.url("https://hello.world").orient(PageOrientation.Landscape).run()
      Path("my-world.pdf").write_bytes(response.content)

To ensure the proper clean up of all used resources, both the client and the route(s) should be used as context manager. If for some reason you cannot, you should .close the client and any routes:

from gotenberg_client import GotenbergClient

try:
  client = GotenbergClient("http://localhost:3000")
  try:
    route = client.merge(["myfile.pdf", "otherfile.pdf"]).run()
  finally:
    route.close()
finally:
  client.close()
