How to use

Ensure you have an access token for the Shopify Storefront API. The token should have the following permissions:

• Read products, variants, and collections
• Read product tags
• Read content like articles, blogs, and comments

Then in your gatsby-config.js add the following config to enable this plugin:

plugins: [
  /*
   * Gatsby's data processing layer begins with “source”
   * plugins. Here the site sources its data from Shopify.
   */
  {
    resolve: "gatsby-source-shopify-multi-language",
    options: {
      // The domain name of your Shopify shop. This is required.
      // Example: 'gatsby-source-shopify-test-shop' if your Shopify address is
      // 'gatsby-source-shopify-test-shop.myshopify.com'.
      // If you are running your shop on a custom domain, you need to use that
      // as the shop name, without a trailing slash, for example:
      // shopName: "gatsby-shop.com",
      shopName: "gatsby-source-shopify-test-shop",

      // An API access token to your Shopify shop. This is required.
      // You can generate an access token in the "Manage private apps" section
      // of your shop's Apps settings. In the Storefront API section, be sure
      // to select "Allow this app to access your storefront data using the
      // Storefront API".
      // See: https://help.shopify.com/api/custom-storefronts/storefront-api/getting-started#authentication
      accessToken: "example-wou7evoh0eexuf6chooz2jai2qui9pae4tieph1sei4deiboj",

      // Set the API version you want to use. For a list of available API versions,
      // see: https://help.shopify.com/en/api/storefront-api/reference/queryroot
      // Defaults to 2023-01
      apiVersion: "2023-01",

      // Set verbose to true to display a verbose output on `npm run develop`
      // or `npm run build`. This prints which nodes are being fetched and how
      // much time was required to fetch and process the data.
      // Defaults to true.
      verbose: true,

      // Number of records to fetch on each request when building the cache
      // at startup. If your application encounters timeout errors during
      // startup, try decreasing this number.
      paginationSize: 250,

      // List of collections you want to fetch.
      // Possible values are: 'shop' and 'content'.
      // Defaults to ['shop', 'content'].
      includeCollections: ["shop", "content"],

      // List of languages you want to fetch.
      // Defaults to ['en'].
      languages: ['en', 'de']

      // Allow overriding the default queries
      // This allows you to include/exclude extra fields when sourcing nodes
      // Available keys are: articles, blogs, collections, products, shopPolicies, and pages
      // Queries need to accept arguments for first and after
      // You will need to include all the fields you want available for a
      // specific key. View the `shopifyQueries Defaults` section below for a
      // full list of keys and fields.
      shopifyQueries: {
        products: `
          query GetProducts($first: Int!, $after: String) {
            products(first: $first, after: $after) {
              pageInfo {
                hasNextPage
              }
              edges {
                cursor
                node {
                  availableForSale
                }
              }
            }
          }
        `,
      },
    },
  },
]

NOTE: By default, all metafields are private. In order to pull metafields, you must first expose the metafield to the Storefront API.

How to query

You can query nodes created from Shopify using GraphQL like the following:

Note: Learn to use the GraphQL tool and Ctrl+Spacebar at http://localhost:8000/___graphql to discover the types and properties of your GraphQL model.

{
  allShopifyProduct {
    edges {
      node {
        id
        title
        handle
        productType
        vendor
        variants {
          id
          title
          price
        }
      }
    }
  }
}

All Shopify data is pulled using the Shopify Storefront API. Data is made available in the same structure as provided by the API, with a few exceptions noted below.

The following data types are available:

| Name | Description | | ------------------ | --------------------------------------------------------------------------------------------------------------------- | | Article | A blog entry. | | Blog | Collection of articles. | | Comment | A comment on a blog entry. | | Collection | Represents a grouping of products that a shop owner can create to organize them or make their shops easier to browse. | | Product | Represents an individual item for sale in a Shopify store. | | ProductOption | Custom product property names. | | ProductVariant | Represents a different version of a product, such as differing sizes or differing colors. | | ShopPolicy | Policy that a merchant has configured for their store, such as their refund or privacy policy. | | ShopDetails | Name, description and money format that a merchant has configured for their store. |

For each data type listed above, shopify${typeName} and allShopify${typeName} is made available. Nodes that are closely related, such as Article and Comment, are provided as node fields as described below.

Note: The following examples are not a complete reference to the available fields for each node. Utilize Gatsby's built-in GraphQL tool to discover the types and properties available.

Query articles

The associated blog data is provided on the blog field. Article comments are provided on the comments field.

        values
      }
    }
  }
}

        type
      }
    }
  }
}

    edges {
      node {
        id
        handle
        title
        body
        bodySummary
      }
    }
  }
}

Query shop details

Shopify merchants can give their shop a name, description and a money format.

{
  shopifyShop {
    name
    description
    moneyFormat
  }
}

Image processing

To use image processing you need gatsby-transformer-sharp, gatsby-plugin-sharp, and their dependencies gatsby-image and gatsby-source-filesystem in your gatsby-config.js.

You can apply image processing to any image field on a node. Image processing of inline images added to description fields is currently not supported.

To access image processing in your queries, you need to use this pattern, where ...ImageFragment is one of the gatsby-transformer-sharp fragments:

{
  allShopifyProduct {
    edges {
      node {
        id
        images {
          localFile {
            childImageSharp {
              ...ImageFragment
            }
          }
        }
      }
    }
  }
}

Full example:

{
  allShopifyProduct {
    edges {
      node {
        id
        images {
          localFile {
            childImageSharp {
              resolutions(width: 500, height: 300) {
                ...GatsbyImageSharpResolutions_withWebp
              }
            }
          }
        }
      }
    }
  }
}

To learn more about image processing, check the documentation of gatsby-plugin-sharp.

Site's gatsby-node.js example

const path = require("path")

exports.createPages = async ({ graphql, boundActionCreators }) => {
  const { createPage } = boundActionCreators

  const pages = await graphql(`
    {
      allShopifyProduct {
        edges {
          node {
            id
            handle
          }
        }
      }
    }
  `)

  pages.data.allShopifyProduct.edges.forEach(edge => {
    createPage({
      path: `/${edge.node.handle}`,
      component: path.resolve("./src/templates/product.js"),
      context: {
        id: edge.node.id,
      },
    })
  })
}

shopifyQueries Defaults

The following can be used in gatsby-config.js to override the default queries.

shopifyQueries: {
  articles: `
    query GetArticles($first: Int!, $after: String) {
      articles(first: $first, after: $after) {

A note on customer information

Not all Shopify nodes have been implemented as they are not necessary for the static portion of a Gatsby-generated website. This includes any node that contains sensitive customer-specific information, such as Order and Payment.

If you are in need of this data (e.g. building a private, internal website), please open an issue. Until then, the nodes will not be implemented to lessen the chances of someone accidentally making private information publicly available.
