Internal GraphQL Server

This extension installs an internal GraphQL Server, that can be invoked within your application, using PHP code.

The internal GraphQL server is accessed via class GatoGraphQL\InternalGraphQLServer\GraphQLServer, through these three methods:

executeQuery: Execute a GraphQL query
executeQueryInFile: Execute a GraphQL query contained in a (.gql) file
executePersistedQuery: Execute a persisted GraphQL query (providing its ID as an int, or slug as a string) (the Persisted Queries extension is required)

These are the method signatures:

namespace GatoGraphQL\InternalGraphQLServer;
 
use PoP\Root\HttpFoundation\Response;
 
class GraphQLServer {
  /**
   * Execute a GraphQL query
   */
  public static function executeQuery(
    string $query,
    array $variables = [],
    ?string $operationName = null,
    int|string|null $schemaConfigurationIDOrSlug = null,
  ): Response {
    // ...
  }
 
 
  /**
   * Execute a GraphQL query contained in a (`.gql`) file
   */
  public static function executeQueryInFile(
    string $file,
    array $variables = [],
    ?string $operationName = null,
    int|string|null $schemaConfigurationIDOrSlug = null,
  ): Response {
    // ...
  }
 
 
  /**
   * Execute a persisted GraphQL query (providing its object
   * of type WP_Post, ID as an int, or slug as a string)
   */
  public static function executePersistedQuery(
    WP_Post|string|int $persistedQuery,
    array $variables = [],
    ?string $operationName = null
  ): Response {
    // ...
  }
}

To execute a GraphQL query and obtain the response content:

use GatoGraphQL\InternalGraphQLServer\GraphQLServer;
 
// Provide the GraphQL query
$query = "{ ... }";
 
// Execute the query against the internal server
$response = GraphQLServer::executeQuery($query);
 
// Get the content and decode it
$responseContent = json_decode($response->getContent(), true);
 
// Access the data and errors from the response
$responseData = $responseContent["data"] ?? [];
$responseErrors = $responseContent["errors"] ?? [];
