gatsby-source-google-scholar

Gatsby source plugin for pulling metadata on scientific publications from Google Scholar.

Live Demo

See the example directory for the demo’s source code.

Install

yarn add gatsby-source-google-scholar

Usage

Include the plugin in your gatsby-config and specify your queries.

// gatsby-config.js
module.exports = {
  siteMetadata: {
    ...
  },
  plugins: [
    {
      resolve: `gatsby-source-google-scholar`,
      options: {
        queries: [`richard feynman`, `albert einstein`],
      },
    },
  ],
}

Specify the metadata you need in a GraphQL query. Here’s everything available.

{
  allGoogleScholar {
    nodes {
      id
      title
      url
      authors {
        name
        url
      }
      preEtAl
      postEtAl
      abstract
      year
      journal
      pdfUrl
      citedByCount
      citedByUrl
      relatedUrl
      allVersionsUrl
    }
  }
}

If you’re only interested in the results for one of your queries, simply filter your results like so:

{
  pubs: allGoogleScholar(
    filter: { internal: { query: { eq: "richard feynman" } } }
  ) {
    nodes {
      title
      url
    }
  }
}

preEtAl and postEtAl are booleans indicating whether Google used ellipsis to signal additional authors before or after the list of authors matching your query, as in this example:

pre- and post et Al.

Here’s an example of the data you’ll get.

Known Issues

The HTTP response received from request seems to break HTML entity encoding. As a result some special characters (like German umlauts) are currently not displayed correctly. PRs welcome!
