GraphQL

GraphQL is a query language for the API. The GraphQL implementation for eZ Platform is located in ezsystems/ezplatform-graphql.

Setup

To use GraphQL, you need to generate the domain schema:

1
2
php bin/console ezplatform:graphql:generate-schema
php bin/console cache:clear

This produces YAML files located in app/config/graphql/ezplatform. They contain information about the domain objects and the fields you can query and operate on.

Note

When you modify Content Types in your installation, you need to regenerate the schema using the command above.

Domain schema

GraphQL for eZ Platform is based on the Content Types, Content Type groups, and Content items defined in the Repository.

For each Content Type the schema exposes a singular and plural field, e.g. article and articles. Use the singular field to query a single Content item, and the plural to get a whole Connection (a list of Content items that supports pagination).

You can request additional content information such as the Section or Objects States, available under the _info field.

You can also query Content Type and Content Type group information through the _info and _types fields.

Repository schema

The repository schema, accessed through _repository, exposes the eZ Platform Repository in a manner similar to the Public PHP API.

The _repository field also enables you to query e.g. Object states configured for the Repository.

Custom schemas

You can also use your own custom schema.

Authentication

GraphQL for eZ Platform supports session-based authentication. You can get your session cookie by logging in through the interface or through a REST request.

Usage

You can access GraphQL with <yourdomain>/graphql.

GraphiQL client

The GraphiQL interactive client is included in the installation. Access it through <yourdomain>/graphiql.

Here you can run your queries and preview the results in an easy-to-read format.

Reference

GraphiQL offers side-by-side reference based on your generated schema in the Docs pane.
