A dockerized web service for creating PDFs from HTML using WeasyPrint
WeasyPrint is a visual rendering engine for HTML and CSS that can export to PDF. It aims to support web standards for printing.
This web service exposes an endpoint for uploading a html file, an optional css file and optional attachments. It responds with the generated PDF.
The web service is written in Python using the aiohttp web server.
To start the webservice just run
docker compose up
The html file and and any additional files must be uploaded as multipart/form-data
with a part named html containing the main HTML content. Assets (e.g. images)
that are referenced in HTML must be prefixed with asset.. Files that should
be attached to the generated pdf must be prefixed with attachment.
Example:
curl -F "html=@tests/index.html" -F "asset.universe.jpg=@tests/universe.jpg" http://localhost:3000 -o test.pdf
For development, you should clone this repo with
git clone https://github.com/enertech-ch/weasyprint-docker.git
and create a new branch.
To test your changes, you can build the image locally and start your local build with
docker compose build weasyprint
docker compose up weasyprint
