A metalsmith plugin to load and render bibtex bibliographies.


$ npm install metalsmith-bibtex

Javascript Usage

Pass the options to Metalsmith#use:

var bibtex = require('metalsmith-bibtex');

    collections: {
        publications: 'bib/publications.bib',
        other: 'bib/other.bib'
    default: 'publications',
    style: 'default', // available styles: ['default', 'ieeetr']
    keystyle: 'numbered',
    sortBy: 'year',
    reverseOrder: true


  • collections: the collections from different bibtex files. Each collection is accessible in the global context through its key as bibtex.key
  • default: key of the default bibliography
  • style: Style for rendering bibliographic entries using handlebars helper. Current styles include:
    • default
    • ieeetr
  • keystyle: specifies if the style of citation in the text and bibliography keys (nothing if undefined). Possible options are numbered and citekey.
  • sortBy: specifies the default field for sorting bibliographies.
  • reverseOrder: specifies if entries should be sorted in reverse order.

Handlebars Helpers

Displaying a bibliography

Displaying an entire collection

The plugin defines a handlebars helper for rendering an entire bibtex collection as formatted HTML. It takes a collection as argument, and optionally a style, and key style:

{{bibliography <collection> [style=bibtex.style.<styleName>] [keystyle='numbered'|'citekey']}}

Displaying a single entry

Similarly, the bibformat helper renders a single bibtex entry:

{{bibformat <entry> [style=bibtex.style.<styleName>]}}

Manipulating CSS

The rendering helpers wrap all the fields of a bibtex entry in html tags with classes such as class="bibtex title", which allows for further styling.

Sorting and Grouping


Collections can be sorted according to any field using the bibsort helper:

{{bibsort <collection> <field> [bool:reverseOrder]}}

Example: rendering a collection sorted by year in descending order:

{{bibliography (bibsort bibtex.other _year true)}}


Collections can be grouped by unique values of a given field:

{{bibgroup <collection> <field>}}

Example of bibliography grouped by entry type:

{{#each (bibgroup bibtex.other _entrytype)}}
    {{bibliography entries}}

Citations inside a page

Another helper allows for referring to publications inside the body of the text, which aggregates the cited items in a local bibtex collection.

The cite command can take the collection as optional argument:

{{#bibcite [bibtex.<collection>]}}citekey1 citekey2{{/bibcite}}
Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor
incididunt ut labore et dolore magna aliqua {{#bibcite}}mccreight1982complete

See 'example' folder for use within a metalsmith project.


This plugin relies on bib2json (all the hard work is there!).
