Extended/Upgraded implementation of GraphQL. This implementation is a package to be installed on top of the PoP API.


Via Composer

composer require pop-api/api-graphql


The source code is hosted on the GatoGraphQL monorepo, under API/packages/api-graphql.

To enable pretty API endpoint /api/graphql/, follow the instructions here

Note: if you wish to install a fully-working API, please follow the instructions under Bootstrap a PoP API for WordPress (even though CMS-agnostic, only the WordPress adapters have been presently implemented).

Automatic namespacing of types

Namespaces (proposed to be added to the GraphQL spec) help manage the complexity of the schema. This can avoid different types having the same name, which can happen when embedding components from a 3rd party.

This is how the normal schema looks like in the GraphQL Voyager:

Interactive schema

This is how it looks in its namespaced version:

Field/directive-based versioning

Fields and directives can be independently versioned, and the version to use can be specified in the query through the field/directive argument versionConstraint.

To select the version for the field/directive, we use the same semver version constraints employed by Composer.
