Source plugins don’t process links and images in blocks of text (i.e. post contents) which makes sourcing from CMS such as WordPress problematic. This plugin solves that for content sourced from WordPress using GraphQL by doing the following:

  • Downloads images and other files to Gatsby static folder
  • Replaces <a> linking to site’s pages with <Link> component
  • Replaces <img> with Gatsby <Img> component leveraging all of the gatsby-image rich functionality

A major update is in the works for the WordPress source plugin and WPGraphQL. This plugin will be radically changed or even become redundant after V4 is completed.


This plugin processes WordPress content sourced with GraphQL. Therefore you must use gatsby-source-graphql and your source WordPress site must use WPGraphQL.

Attention: does not work with gatsby-source-wordpress.

How to install

yarn add gatsby-wpgraphql-inline-images
  resolve: 'gatsby-wpgraphql-inline-images',
  options: {
    wordPressUrl: 'https://mydomain.com/',
    uploadsUrl: 'https://mydomain.com/wp-content/uploads/',
    processPostTypes: ['Page', 'Post', 'CustomPost'],
    graphqlTypeName: 'WPGraphQL',
    httpHeaders: {
      Authorization: `Bearer ${process.env.GITHUB_TOKEN}`,

Available options

wordPressUrl and uploadsUrl contain URLs of the source WordPress site and it’s uploads folder respectively.

processPostTypes determines which post types to process. You can include custom post types as defined in WPGraphQL.

graphqlTypeName should contain the same typeName used in gatsby-source-graphql parameters.

generateWebp (boolean) adds WebP images.

httpHeaders Adds extra http headers to download request if passed in.

debugOutput (boolean) Outputs extra debug messages.

How do I use this plugin?

Downloading and optimizing images is done automatically via resolvers. You need to include uri in all queries that will be processed by the plugin otherwise they will be ignored.

query GET_PAGES {
  wpgraphql {
    pages {
      nodes {

There is an additional step of processing content that must be added manually to a page template. This additional processing replaces remote urls with links to downloaded files in Gatsby’s static folder.

import contentParser from 'gatsby-wpgraphql-inline-images';

replace <div dangerouslySetInnerHTML={{ __html: content }} /> with this

<div>{contentParser({ content }, { wordPressUrl, uploadsUrl })}</div>

Where content is the original HTML content and URLs should use the same values as in the options above. contenParser returns React object.

The recommended handling of featuredImage and WordPress media in general is described by henrikwirth in this article and this gist.

WordPress galleries

WordPress galleries may need some additional styling applied and this was intentionally left out of the scope of this plugin. Emotion Global Styles may be used or just import sass/css file.

.gallery {
  display: flex;
  flex-direction: row;
  flex-wrap: wrap;
.gallery-item {
  margin-right: 10px;

Gatsby themes support

Inserted <Img> components have variant: 'styles.SourcedImage' applied to them.

Examples of usage

I’m going to use gatsby-wpgraphql-blog-example as a starter and it will source data from a demo site at yourdomain.dev.

Add this plugin to the gatsby-config.js

  resolve: 'gatsby-wpgraphql-inline-images',
  options: {
    wordPressUrl: `https://yourdomain.dev/`,
    uploadsUrl: `https://yourdomain.dev/wp-content/uploads/`,
    processPostTypes: ["Page", "Post"],
    graphqlTypeName: 'WPGraphQL',

Change url in gatsby-source-graphql options to https://yourdomain.dev/graphql

Page templates are stored in src/templates. Let’s modify post.js as an example.

Importing contentParser

import contentParser from 'gatsby-wpgraphql-inline-images';

For simplicty’s sake I’m just going to add URLs directly in the template.

const pluginOptions = {
  wordPressUrl: `https://yourdomain.dev/`,
  uploadsUrl: `https://yourdomain.dev/wp-content/uploads/`,

and replace dangerouslySetInnerHTML with this

<div>{contentParser({ content }, pluginOptions)}</div>

The modified example starter is available at github.com/progital/gatsby-wpgraphql-blog-example.
