How to use

// In your gatsby-config.js
module.exports = {
  plugins: [
    // after a markdown or Mdx transformer
    {
      resolve: `gatsby-transformer-markdown-references`,
      options: {
        types: ["Mdx"], // or ["MarkdownRemark"] (or both)
      },
    },
  ],
};

Configuration options

types [Array][optional]

The types of the nodes to transform. Defaults to ['Mdx']

How to query for references

Two types of references are available: outboundReferences and inboundReferences.

The fields will be created in your site's GraphQL schema on the nodes of types specified in the options.

{
  allMdx {
    outboundReferences {
      ... on Mdx {
        id
        parent {
          id
        }
      }
    }
    inboundReferences {
      ... on Mdx {
        id
        parent {
          id
          ... on RoamPage {
            title
          }
        }
      }
    }
  }
}
