gatsby-image-graphql-schema

Gatsby image from GraphQL schema

Use case

This plugin generates fileNodes in your graphQL schema and add File type to it. You can now use gatsby-plugin-sharp and gatsby-transformer-sharp in your GraphQL schema.

Installation

Add plugin to your project's dependencies

yarn add gatsby-image-graphql-schema

Update and configure plugin in your gatsby-config file :

...
{
  resolve: "gatsby-image-graphql-schema",
  options: {
    imageNames: ["publicURL", "strapi_UploadFile.url"],
    schemaTypeName: "drupal",
  },
},

• imageNames is the name of the fields where your images url appears in your graphQL schema. With a dot separation ("."), you can set a specific parent type for field name. In this example, the plugin will take all publicURL field names and only url field name with strapi_UploadFile parent type

• schemaTypeName is the root schema type name where the plugin will search in to transform your images. (you must have the same value as the typeName options in the gatsby-source-graphql plugin).

• baseUrl [optional] this plugin option allows you to concatenate image url with a base path (usefull when you only have the name of your images in your query result)

Result

You can now query your images and they come with access to childImageSharp feature :

thumbnail {
  url
  urlSharp {
    childImageSharp {
      fixed(width: 500, height: 500) {
        ...GatsbyImageSharpFixed_withWebp
      }
    }
  }
}
