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.

It supports both normal citations (such as [@foo]) and in-text citation (such as @foo), as well as author-date, numerical, and note styles.

API and options follows very closely to Rmarkdown and Pandoc

Intended for usage in Node. If you would like to manage citations in the browser, you should look into using citeproc-js directly.

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

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">
  <div class="csl-entry">
    Nash, J. (1950). Equilibrium points in n-person games.
    <i>Proceedings of the National Academy of Sciences</i>, <i>36</i>(1), 48–49.
  </div>
</div>

Limitations

1. link-citations is not implemented.
2. In-text citation does not parse additional locator information e.g. @foo [p. 33], please use either [@foo, p. 33] or @foo.
3. Parsing of locators such as page or chapter is done by heuristics and limited to only en content.
4. Does not support using curly braces to protect citation key or locator information.
