Rehype-Citation
rehype plugin to nicely format citations in markdown documents and insert bibliography in html format. It is meant to be used as a server side plugin and neatly integrates citeproc-js and citation-js within the remark-rehype ecosystem. Parsing of citations and all the wonderful regexes are adapted from Zettlr.
It supports both normal citations (such as [@foo]) and in-text citation (such as @foo), as well as author-date, numerical, and note styles.
Note styles is only compatible with Github Formatted Markdown (GFM). It is recommended to run remark-gfm before rehype-citation to ensure all footnote elements are correctly formatted.
API and options follows very closely to Rmarkdown and Pandoc
Examples
Installation
This package is ESM only: Node 12+ is needed to use it and it must be imported instead of required.
npm install rehype-citation
Usage
If you are using the plugin in a node environment, import from rehype-citation/node. For browser environments, import from rehype-citation/browser.
The following files are exported:
generator, generator function. Can be used to generate a rehype citation plugin. Takes in a citation-js Cite class. cite, a citation-js Cite instance. Add your own CSL / locales before passing in to the plugin generator . rehype-citation, re-exports the above 2 packages with a pre-configured rehype-citation plugin ready to use. Importing from rehype-citation directs to this file.
Use this package as a rehype plugin.
Some examples of how you might do that:
import rehype from 'rehype'
import rehypeCitation from 'rehype-citation'
rehype().use(rehypeCitation).process(/* some html */)
Sample markdown to HTML output
Input:
My markdown text [@Nash1950]
HTML Output:
<div>My markdown text (Nash, 1950)</div>
<div id="refs" class="references csl-bib-body">

The default plugin comes configured with the en-US locale and the following CSL styles: apa, vancouver, harvard1, chicago and mla.
Use the generator function to customize your own remark-citation plugin and add your own CSL styles or locales.
import Cite from 'rehype-citation/cite'
import rehypeCitationGenerator from 'rehype-citation/generator'
import myStyle from '../style'
import myLocale from '../locale'
const config = Cite.plugins.config.get('@csl')
config.templates.add('mystyle', myStyle)
config.locales.add('myLocale', myLocale)
const rehypeCitation = rehypeCitationGenerator(Cite)
