Gatsby transformer Bibtex

This plugin relies on gatsby-source-filesystem to detect bibtex files in your project and provide the associated nodes in GraphQL queries.


Adding the plugin

In your gatsby-config.js, add gatsby-source-filesystem and gatsby-transformer-bibtex, making sure that the former is before the latter.

plugins: [
  // ...,
    resolve: `gatsby-source-filesystem`,
    options: {
      name: `documents`,
      path: `${__dirname}/src/assets/documents`,
  // ...

The path you specify in the options of gatsby-source-filesystem must contain all the bibtex files, with a .bib extension.

Static Queries

Once added, the plugin will add Reference nodes to your GraphQL queries, allowing you for example to write the following query in a StaticQuery component or a page:

query {
  allReference {
    edges {
      node {

Special fields

Every field is simply the string value that was in the corresponding Bibtex entry, except for some fields that have a special behaviour.

  • The entry_type field contains the type of the entry. For example, an entry starting with @article{... will have "article" in its entry_type field.
  • The date field is either the provided issue_date if it exists, or year if it does not. It is always a string.
  • The authors field is a list of the authors’ names, that has been extracted from the bibtex.
  • The raw field contains the entire bibtex entry as a raw string.
  • The youtubeId is created if a youtube field is in your bibtex file. If your youtube field contains a youtubeId, it’s just copied, if it contains a youtube link, the id is extracted from it.

Working with files

It is possible to work with local files, and to create fields of type File in your nodes. If in every of your entries, for a given field, the value is not specified (null) or it is a relative path to a file, then Gatsby will transform it into a File field provided by gatsby-source-filesystem. In particular, this field contains a publicURL field that is useful if you want to add a link to the file.

For example, if the path you gave to gatsby-source-fileystem contains

    ├── paper_a.pdf
    └── publications.bib

where publications.bib contains

 author = {Name, Your and Of-Yours, Coauthor},
 title = {Paper A},
 file = {paper_a.pdf} % path relative to where this .bib file is

Then you can create a component in the following way:

import React from "react"
import { StaticQuery, graphql } from "gatsby"

const ComponentName = () => (
        reference(key: {eq: "some_key"}) {
          file {
    render={data => <a href={data.reference.file.publicURL}>Link to Paper A</a>}

export default ComponentName


This project is not extremely mature, but I’ve had feedback that it is used. PRs and issues are more than welcome 😁
