Light GraphQL

Light GraphQL is a lightweight GraphQL server implementation designed for simplicity and ease of use. This project demonstrates how to set up a basic GraphQL server using PHP.

This library is built using several dependencies, including thecodingmachine/graphqlite, which provides annotations and tools for creating GraphQL APIs in PHP. Other key dependencies include:

• league/container: A lightweight dependency injection container.
• symfony/cache: A caching library for optimizing performance.

These libraries work together to provide a robust and flexible foundation for building GraphQL servers.

Installation

Key Components

• Schema Factory: The schema is dynamically created using the SchemaFactory provided by the Light\GraphQL\Server. It allows adding namespaces for controllers.

• Controllers: The Controllers namespace is used to define resolvers for GraphQL queries.

• GraphQL Execution: The Server::executeQuery method is used to execute the GraphQL query against the schema. In the provided example, the query $query is executed, and the result is converted to an array using toArray().

Usage Example

ServerRequestInterface handling

use Controllers\RootController;
use GraphQL\GraphQL;

$server = new \Light\GraphQL\Server();
$server->getSchemaFactory()->addNamespace("Controllers");

$response=$server->handle($request);
