Built-in producers

The Drupal GraphQL module comes with many built in data producers to help solve typical scenarios you might need to support in your API. In this section we will explain briefly each one of them and how it can be used.
As the module is developed more data producers can be added to the core module. Its also important to note that many useful data producers can live in "user land" as contrib modules can add support for GraphQL by adding custom data producers (e.g. a Metatag data producer that lets you resolve metatags using the Metatag module or a Search API integration as seen in GraphQL Search API)

Entity uuid (entity_uuid) : Returns the entity's uuid.
Image data producers
Image derivative (image_derivative) : Returns image derivative properties (image style url width and height) given a image/file entity and a style name.
Image Style URL (image_style_url) : Returns the URL of an image derivative given a an image derivative.
Image url (image_url) : Returns the url of an image entity given an image/file entity
Entity reference data producers
Entity Reference (entity_reference) : Loads entities from an entity reference field given an entity and a field name.
Menu Data producers

Typed data
Property path (property_path) : Resolves a typed data value at a given property path. Takes as arguments a path, value and type (optional).
How to use the producers
This is no doubt a very long list of supported properties by itself, but just as it is it provides no real value. The real value is in how these data producers can be combined to perform complex queries and mutations.
We will look how to use the data producers together in the section "Queries" where we will do many common query scenarios like querying nodes or taxonomies, menus, custom fields, entity reference fields etc..
