The official Gatsby source plugin for Hygraph projects

Demo • gatsby-starter-hygraph-blog • Join us on Slack • Login to Hygraph • @hygraphcom

yarn add gatsby-source-graphcms gatsby-plugin-image

Note: Gatsby v4 requires Node.js >= 14.15.

We recommend using environment variables with your Hygraph token and endpoint values. You can learn more about using environment variables with Gatsby here.

// gatsby-config.js
module.exports = {
  plugins: [
    {
      resolve: 'gatsby-source-graphcms',
      options: {
        endpoint: process.env.HYGRAPH_ENDPOINT,
      },
    },
  ],
}

You can also provide an auth token using the token configuration key. This is necessary if your Hygraph project is not publicly available, or you want to scope access to a specific content stage (i.e. draft content).

// gatsby-config.js
module.exports = {
  plugins: [
    {
      resolve: 'gatsby-source-graphcms',
      options: {
        endpoint: process.env.HYGRAPH_ENDPOINT,
        token: process.env.HYGRAPH_TOKEN,
      },
    },
  ],
}

If using Hygraph localisation, this plugin provides support to build nodes for all provided locales.

Update your plugin configuration to include the locales key.

// gatsby-config.js
module.exports = {
  plugins: [
    {
      resolve: 'gatsby-source-graphcms',
      options: {
        endpoint: process.env.HYGRAPH_ENDPOINT,
        locales: ['en', 'de'],
      },
    },
  ],
}

To query for nodes for a specific locale, use the filter query argument.

{
  enProducts: allGraphCmsProduct(filter: { locale: { eq: en } }) {
    nodes {
      name
    }
  }
}

Check out the demo source for an example of a localisation implementation.

This plugin provides support to build nodes for entries from multiple Content Stages.

The provided Content Stages must be accessible according to the configuration of your project's API access. If providing a token, then that Permanent Auth Token must have permission to query data from all provided Content Stages.

The example below assumes that both the DRAFT and PUBLISHED stages are publicly accessible.

// gatsby-config.js
module.exports = {
  plugins: [
    {
      resolve: 'gatsby-source-graphcms',
      options: {
        endpoint: process.env.HYGRAPH_ENDPOINT,
        stages: ['DRAFT', 'PUBLISHED'],
      },
    },
  ],
}

To query for nodes from a specific Content Stage, use the filter query argument.

{
  allGraphCmsProduct(filter: { stage: { eq: DRAFT } }) {
    nodes {
      name
    }
  }
}

Requires gatsby-plugin-image as a project dependency.

This source plugin supports gatsby-plugin-image for responsive, high performance Hygraph images direct from our CDN.

Use the gatsbyImageData resolver on your GraphCMS_Asset nodes.

{
  allGraphCmsAsset {
    nodes {
      gatsbyImageData(layout: FULL_WIDTH)
    }
  }
}

NOTE: gatsby-plugin-sharp needs to be listed as a dependency on your project if you plan to use placeholder TRACED_SVG or DOMINANT_COLOR.

For more information on using gatsby-plugin-image, please see the documentation.

If you prefer, the source plugin also provides the option to download and cache Hygraph assets in your Gatsby project.

To enable this, add downloadLocalImages: true to your plugin configuration.

// gatsby-config.js
module.exports = {
  plugins: [
    {
      resolve: 'gatsby-source-graphcms',
      options: {
        endpoint: process.env.HYGRAPH_ENDPOINT,
        downloadLocalImages: true,
      },
    },
  ],
}

This adds a localFile field to the GraphCMS_Asset type which resolves to the file node generated at build by gatsby-source-filesystem.

{
  allGraphCmsAsset {
    nodes {
      localFile {
        childImageSharp {
          gatsbyImageData(layout: FULL_WIDTH)
        }
      }
    }
  }
}

This source plugin provides the option to build markdown nodes for all RichText fields in your Hygraph schema, which in turn can be used with MDX.

To enable this, add buildMarkdownNodes: true to your plugin configuration.

// gatsby-config.js
module.exports = {
  plugins: [
    {
      resolve: 'gatsby-source-graphcms',
      options: {
        endpoint: process.env.HYGRAPH_ENDPOINT,
        buildMarkdownNodes: true,
      },
    },
  ],
}

Enabling this option adds a markdownNode nested field to all RichText fields on the generated Gatsby schema.

You will need to rebuild your graphcms-fragments if you enable embeds on a Rich Text field, or you add/remove additional fields to your Hygraph schema.

These newly built nodes can be used with gatsby-plugin-mdx to render markdown from Hygraph.

Once installed, you will be able to query for MDX fields using a query similar to the one below.

{
  allGraphCmsPost {
    nodes {
      id
      content {
        markdownNode {
          childMdx {
            body
          }
        }
      }
    }
  }
}

Check out the demo source for an example of a full MDX implementation.

The source plugin will generate and save GraphQL query fragments for every node type. By default, they will be saved in a graphcms-fragments directory at the root of your Gatsby project. This can be configured:

If using multiple instances of the source plugin, you must provide a value to prevent type and/or fragment conflicts.

// gatsby-config.js
module.exports = {
  plugins: [
    {
      resolve: 'gatsby-source-graphcms',
      options: {
        endpoint: process.env.HYGRAPH_ENDPOINT,
        fragmentsPath: 'my-query-fragments',
      },
    },
  ],
}

The generated fragments are then read from the project for subsequent builds. It is recommended that they are checked in to version control for your project.

Should you make any changes or additions to your Hygraph schema, you will need to update the query fragments accrdingly. Alternatively they will be regnerated on a subsequent build after removing the directory from your project.

In some instances, you may need modify query fragments on a per type basis. This may involve:

• Removing unrequired fields
• Adding new fields with arguments as an aliased field

For example, adding a featuredCaseStudy field:

fragment Industry on Industry {
  featuredCaseStudy: caseStudies(where: { featured: true }, first: 1)
}

Field arguments cannot be read by Gatsby from the Hygraph schema. Instead we must alias any required usages as aliased fields. In this example, the featuredCaseStudy field would then be available in our Gatsby queries:

{
  allGraphCmsIndustry {
    nodes {
      featuredCaseStudy {
        ...
      }
    }
  }
}

If you spot an issue, or bug that you know how to fix, please submit a pull request.

When working locally you'll need to run yarn compile and yarn dev using Yarn workspaces that will let you test/develop on the demo Gatsby app in this project. You may need to yarn clean occcasionally too.
