Standard Usage

Before getting started, install Wkhtmltopdf. Ghostscript is optional. If you prefer to skip installation of node, wkhtmltopdf and ghostscript on your machine see Docker Usage below.

Here are a few examples of this software in action. Run the following commands to generate your PDFs:

# Genrate PDF from specific site under `docs` scope
npx docusaurus-wkhtmltopdf -u https://docusaurus.io/docs

# Example with more flags: create table of contents, compress the file, and pipe to stdout
npx docusaurus-wkhtmltopdf -u https://docusaurus.io/docs --compress --toc --stdout > documentation.pdf

To generate PDF from a local Docusaurus instance. You need to first build the site locally:

# Build the site
yarn build

# Serve built site locally
yarn serve

# Generate PDF from local Docusaurus instance
npx docusaurus-wkhtmltopdf -u http://localhost:4000/docs # Change port to your serving port

Docker Usage

The docker image comes with a working environment so no other external software is needed. Here are a few examples of this software in action. Run the following commands to generate your desired PDF:

# Generate PDF from specific site under `docs` scope. Please note that the folder with the generated file can be found in /tmp/pdf
docker run --rm -v /tmp/pdf:/d2p/pdf nuxnik/docusaurus-to-pdf -u https://docusaurus.io/docs

# Let's use some more flags: create table of contents, compress the file, and pipe from stdout to documentation.pdf
docker run --rm nuxnik/docusaurus-to-pdf -u https://docusaurus.io/docs --toc --compress --stdout > documentation.pdf

Modifications

Like mr-pdf, this package looks for the next pagination links on generated Docusaurus site. Collect them in a list and then pass the list to wkhtmltopdf to generate the PDF. You can specify the CSS selector if you're using a custom Docusaurus theme:

npx docusaurus-wkhtmltopdf -u https://docusaurus.io/docs --selector 'nav.custom-pagination-item--next > a'

You can also customize the CSS of the pages which are scraped by the crawler by modifying "print.css" file located in the project root. This CSS file is applied to the pages before being processed through Wkhtmltopdf. Depending on how this file is modified, will change the overall look of the generated PDF file.
