Example: Create a custom WordPress sitemap with vanilla WPGraphQL and Apollo Client

This example demonstrates how to generate a custom sitemap in a headless WordPress application using the Next.js framework. The example app fetches data from WordPress using Apollo Client and WPGraphQL. This example is using only the existing WPGraphQL endpoints, without extending it.

The example includes a wp-env setup, which will allow you to build and start this example quickly. With this wp-env setup, you don't need to have a separate WordPress instance or demo data to inspect the example.

Features

1. Fetching sitemap data with the API allows maximum customizability
2. An identical WordPress sitemap structure in the headless setup
3. Custom XSLT styles
4. Configured WordPress instance with demo data and required plugins, using wp-env
5. Sitemaps for custom post and taxonomy types

Screenshots

After following the installation steps, you should have the example sitemap pages as shown in the screenshots below:

Running the example with wp-env

Prerequisites

• Node.js (v18+ recommended)
• Docker (if you plan on running the example see details below)

Note Please make sure you have all prerequisites installed as mentioned above and Docker running (docker ps)

Setup Repository and Packages

• Clone the repo git clone https://github.com/wpengine/hwptoolkit.git
• Install packages cd hwptoolkit && npm install
• Setup a .env file under examples/next/custom-sitemap-vanilla-wpgraphql/example-app and add these values inside:

NEXT_PUBLIC_WORDPRESS_URL=http://localhost:8888
NEXT_PUBLIC_URL=http://localhost:3000

or run the command below:

echo "NEXT_PUBLIC_WORDPRESS_URL=http://localhost:8888\\nNEXT_PUBLIC_URL=http://localhost:3000" > examples/next/custom-sitemap-vanilla-wpgraphql/example-app/.env

Build and start the application

• cd examples/next/custom-sitemap-vanilla-wpgraphql
• Then run npm run example:build will build and start your application.
• This does the following:
  • Starts up wp-env
  • Imports the database from wp-env/db/database.sql
  • Install Next.js dependencies for example-app
  • Runs the Next.js dev script

Congratulations, WordPress should now be fully set up.
