⚙️ How To Use Absolute Image Paths In Json — Gatsbyjs

If you want to use images in JSON imported with gatsby-transformer-json this is the right place to get some help.

Why

With the new version of Gatsby and the deprecation of gatsby-image something has changed. The images don’t show up on the page.

I’ve found the solution in an answer on Github under an issue that was asking something similar.

I know, I know. The issue speaks about “absolute image paths” but this is the only solution that it’s actually working for me.

How

• Make sure you already have gatsby-transformer-json installed, configured, and working.
• Open your gatsby-node.js file and add this snippet:

const path = require(“path”)

const getFileNode = (options) => (source, _, context, info) => {
  const { fieldName } = info
  const partialPath = source[fieldName]

  if (!partialPath) {
    return null
  }

  const filePath = path.join(__dirname, options.path, partialPath)

  const fileNode = context.nodeModel.runQuery({
    firstOnly: true,
    type: ‘File’,
    query: {
      filter: {
        absolutePath: {
          eq: filePath
        }
      }
    }
  })

  if (!fileNode) {
    return null
  }

  return fileNode
}

exports.createSchemaCustomization = ({ actions }) => {
  const { createTypes, createFieldExtension } = actions

  createFieldExtension({
    name: “fileByAbsolutePath”,
    args: {
      path: {
        type: “String!”,
        defaultValue: “”
      }
    },
    extend: (options) => ({
      resolve: getFileNode(options)
    })
  })

  createTypes(`
    type LocalContentCities implements Node {
      image: File @fileByAbsolutePath(path: “src/images”)
    }
  `)
}

• Replace LocalContentCities with your actual resource name.

Done.

For the usage in your page/component just follow the instructions here: gatsby-plugin-image.
