Overview

I tried GraphQL with Drupal, so this is a personal note for future reference. The following document was helpful.

README | GraphQL
drupal-graphql.gitbook.io

This assumes Drupal installed on Amazon Lightsail.

Module Installation

Install the following module.

GraphQL
This module lets you craft and expose a GraphQL schema for Drupal 10 and 11. It is is built around webonyx/graphql-php.
Drupal.org

However, it was necessary to install the following module beforehand.

Typed Data API enhancements
The Typed Data API Enhancements module adds functionality to the core Drupal TypedData API without altering the operation of the existing core API.
Drupal.org

As a result, the installation was completed with the following commands.

cd /home/bitnami/stack/drupal
composer require 'drupal/typed_data:^1.0@beta'
composer require 'drupal/graphql:^4.4'

Module Installation from GUI

I checked all three related modules below and installed them.

Configuration

Access the following URL.

/admin/config/graphql

Under "Create server", I configured it as follows. I named it test_server.

Explore

Access the following URL.

/admin/config/graphql/servers/manage/test_server/explorer

You will be redirected to the following screen.

Let's try the following query.

{
  articles {
    total
  }
}

The following result is obtained.

{
  "data": {
    "articles": {
      "total": 5054
    }
  }
}

Summary

In the future, I would like to investigate usage methods with custom schemas as well. I hope this serves as a useful reference.
