Introduction
A PDF generator for Docusaurus 1.x documentation pages, based on Docusaurus and Puppeteer. It's sad but even in 2020, PDF based documentation is still a thing...
This project is build on Docusaurus 1.x. I basically took the code and modified it to generate PDF's.
Please note
Puppeteer does not yet support individual headers / footers for the cover page. Therefore this package generates a PDF with just uses easy-pdf-merge See this SO question
Puppeteer does not yet support the generation of TOCs. See this feature request and this Chromium bug. Therefore this package generates a PDF, then parses it again to update the page numbers in the TOC. Therefore the pdfFooterParser...
Installation
Install in your website folder and add the following script to the package.json of your website.
"build:pdf": "papersaurus-build",Configuration
Adapt the siteConfig.js of your website to contain the following keys:
pdfBuildDir
The directory in your website folder in which the PDF files will be saved. Depending on the usage, it is useful to have this option available. For example if set to build, the PDF are saved next to the (previously) generated website. In this case it is easy to download the PDF files from the web based documentation.
Default: print
pdfBuildDirCleanUp
If set to true, the directory passed in pdfBuildDir will be removed before generating the PDF files. In case the PDF files should be saved in your build directory, set this configuration key to false in order to not delete the previously generated static website.
Default: true
pdfIgnoreDocs
Array of doc ID's to ignore.

},Puppeteer uses classes to inject values at print time. See: https://pptr.dev/#?product=Puppeteer&version=v3.0.4&show=api-pagepdfoptions
pdfAuthor
String you would like to use as author.
pdfFooterParser
In order to update the TOC with the correct page numbers, this package has to parse the generated PDF and then manually update the TOC. In order to split the parsed text by pages, a regex expression is used to identify the content footer text. Think of calling jQuery's $.text() on the footer wrapper. The regular expression must match this text.
Example:
/© Your Company\d{4}-\d{2}-\d{2}Page \d* \/ \d*/g
Limitation
- Just documentations are generated, no pages or blog posts
- No support for translations
