GraphQL extension exposes a /graphql endpoint in MediaWiki as a proxy for the Action API and REST API.

Installation

• Download and move the extracted GraphQL folder to your extensions/ directory.
  Developers and code contributors should install the extension from Git instead, using:cd extensions/
git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/GraphQL
• Only when installing from Git, run Composer to install PHP dependencies, by issuing composer install --no-dev in the extension directory. (See task T173141 for potential complications.)
• Add the following code at the bottom of your LocalSettings.php file:

  wfLoadExtension( 'GraphQL' );
  

• Install npm dependencies with npm install in the extension directory
•  Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

Usage

• The GraphQL endpoint is exposed at Special:GraphQL with an alias at /graphql.
• The GraphQL Sandbox can be accessed at Special:GraphQLSandbox. The sandbox uses the GraphiQL in-browser GraphQL IDE.
• The federation service endpoint is exposed at Special:GraphQL/Federation with an alias at /graphql/federation.

Project Goals

1. A proxy for the Action API and REST API. This extension should not expose functionality that is not already available in the existing APIs. This extension will therefore exist as a convenience to developers making bulk or recursive requests to the existing APIs.
2. A federated service. This extension should be compatible with Apollo's Federation Specification or other federated specifications to allow a centralized gateway like Tool:GraphQL to make distributed GraphQL queries.
