<h1>HTML to be rendered to PDF</h1>
<p>This document will be rendered to PDF.</p>
</body>
</html>(Note that you have to set Accept: application/pdf header.)
And then you will get a PDF document through its response e.g.:
HTTP/1.1 200 OK

Getting started using Docker
Due to its non-Python dependencies the easist way to use this is using Docker. The official Docker image exposes 8080 port for HTTP server.
$ docker run -p 8080:8080 spoqa/html2pdf-serverIf you need a pong endpoint for health check specify PONG_PATH environment variable:
$ docker run -e PONG_PATH=/ping/ -p 8080:8080 spoqa/html2pdf-server
Serving on http://0.0.0.0:8080Getting started without Docker
Installation
You can install it using pip:
$ pip install --user git+git://github.com/spoqa/html2pdf-server.gitNote that WeasyPrint has several dependencies that need to be installed using system package managers e.g. APT, Homebrew. Read the docs.
Running server
Use html2pdfd command:
$ html2pdfd --port 8080
Serving on http://0.0.0.0:8080Or you can use your preferred WSGI server as well (WSGI endpoint is html2pdfd:app):
$ aiohttp-wsgi-serve html2pdfd:app
Serving on http://:::8080 http://0.0.0.0:8080License
Distributed under AGPLv3 or later.
