Version: 4.1

Getting started with any framework

If you are using Symfony 4.x, checkout the Symfony bundle.


Open a terminal in your current project directory and run:

$ composer require thecodingmachine/graphqlite


In order to bootstrap GraphQLite, you will need:

  • A PSR-11 compatible container
  • A PSR-16 cache

Additionally, you will have to route the HTTP requests to the underlying GraphQL library.

GraphQLite relies on the webonyx/graphql-php library internally. This library plays well with PSR-7 requests and we also provide a PSR-15 middleware.


Webonyx/graphql-php library requires a Schema in order to resolve GraphQL queries. We provide a SchemaFactory class to create such a schema:

use TheCodingMachine\GraphQLite\SchemaFactory;

// $cache is a PSR-16 compatible cache
// $container is a PSR-11 compatible container
$factory = new SchemaFactory($cache, $container);

$schema = $factory->createSchema();

You can now use this schema with Webonyx GraphQL facade or the StandardServer class.

The SchemaFactory class also comes with a number of methods that you can use to customize your GraphQLite settings.

// Configure an authentication service (to resolve the @Logged annotations).
$factory->setAuthenticationService(new VoidAuthenticationService());
// Configure an authorization service (to resolve the @Right annotations).
$factory->setAuthorizationService(new VoidAuthorizationService());
// Change the naming convention of GraphQL types globally.
$factory->setNamingStrategy(new NamingStrategy());
// Add a custom type mapper.
// Add a custom type mapper using a factory to create it.
// Type mapper factories are useful if you need to inject the "recursive type mapper" into your type mapper constructor.
// Add a root type mapper.
// Add a parameter mapper.
// Add a query provider. These are used to find queries and mutations in the application.
// Add a query provider using a factory to create it.
// Query provider factories are useful if you need to inject the "fields builder" into your query provider constructor.
// Add custom options to the Webonyx underlying Schema.
// Configures the time-to-live for the GraphQLite cache. Defaults to 2 seconds in dev mode.
// Enables prod-mode (cache settings optimized for best performance).
// This is a shortcut for `$schemaFactory->setGlobTtl(null)`
// Enables dev-mode (this is the default mode: cache settings optimized for best developer experience).
// This is a shortcut for `$schemaFactory->setGlobTtl(2)`

GraphQLite context

Webonyx allows you pass a "context" object when running a query. For some GraphQLite features to work (namely: the prefetch feature), GraphQLite needs you to initialize the Webonyx context with an instance of the TheCodingMachine\GraphQLite\Context\Context class.

For instance:

use TheCodingMachine\GraphQLite\Context\Context;

$result = GraphQL::executeQuery($schema, $query, null, new Context(), $variableValues);

Minimal example

The smallest working example using no framework is:

use GraphQL\GraphQL;
use GraphQL\Type\Schema;
use TheCodingMachine\GraphQLite\SchemaFactory;
use TheCodingMachine\GraphQLite\Context\Context;

// $cache is a PSR-16 compatible cache.
// $container is a PSR-11 compatible container.
$factory = new SchemaFactory($cache, $container);

$schema = $factory->createSchema();

$rawInput = file_get_contents('php://input');
$input = json_decode($rawInput, true);
$query = $input['query'];
$variableValues = isset($input['variables']) ? $input['variables'] : null;

$result = GraphQL::executeQuery($schema, $query, null, new Context(), $variableValues);
$output = $result->toArray();

header('Content-Type: application/json');
echo json_encode($output);

PSR-15 Middleware

When using a framework, you will need a way to route your HTTP requests to the webonyx/graphql-php library.

If the framework you are using is compatible with PSR-15 (like Slim PHP or Zend-Expressive / Laminas), GraphQLite comes with a PSR-15 middleware out of the box.

In order to get an instance of this middleware, you can use the Psr15GraphQLMiddlewareBuilder builder class:

// $schema is an instance of the GraphQL schema returned by SchemaFactory::createSchema (see previous chapter)
$builder = new Psr15GraphQLMiddlewareBuilder($schema);

$middleware = $builder->createMiddleware();

// You can now inject your middleware in your favorite PSR-15 compatible framework.
// For instance:

The builder offers a number of setters to modify its behaviour:

$builder->setUrl("/graphql"); // Modify the URL endpoint (defaults to /graphql)
$config = $builder->getConfig(); // Returns a Webonyx ServerConfig object. Use this object to configure Webonyx in details.

$builder->setResponseFactory(new ResponseFactory()); // Set a PSR-18 ResponseFactory (not needed if you are using zend-framework/zend-diactoros ^2
$builder->setStreamFactory(new StreamFactory()); // Set a PSR-18 StreamFactory (not needed if you are using zend-framework/zend-diactoros ^2
$builder->setHttpCodeDecider(new HttpCodeDecider()); // Set a class in charge of deciding the HTTP status code based on the response.


In this example, we will focus on getting a working version of GraphQLite using:

  • Zend Stratigility as a PSR-15 server
  • mouf/picotainer (a micro-container) for the PSR-11 container
  • symfony/cache for the PSR-16 cache

The choice of the libraries is really up to you. You can adapt it based on your needs.

use Laminas\Diactoros\Response;
use Laminas\Diactoros\ServerRequest;
use Laminas\Diactoros\ServerRequestFactory;
use Zend\HttpHandlerRunner\Emitter\SapiStreamEmitter;
use Zend\Stratigility\Middleware\ErrorResponseGenerator;
use Zend\Stratigility\MiddlewarePipe;
use Laminas\Diactoros\Server;
use Zend\HttpHandlerRunner\RequestHandlerRunner;

require_once __DIR__ . '/vendor/autoload.php';

$container = require 'config/container.php';

$serverRequestFactory = [ServerRequestFactory::class, 'fromGlobals'];

$errorResponseGenerator = function (Throwable $e) {
$generator = new ErrorResponseGenerator();
return $generator($e, new ServerRequest(), new Response());

$runner = new RequestHandlerRunner(
new SapiStreamEmitter(),

Here we are initializing a Zend RequestHandler (it receives requests) and we pass it to a Zend Stratigility MiddlewarePipe. This MiddlewarePipe comes from the container declared in the config/container.php file:



use GraphQL\Type\Schema;
use Mouf\Picotainer\Picotainer;
use Psr\Container\ContainerInterface;
use Psr\SimpleCache\CacheInterface;
use Symfony\Component\Cache\Simple\ApcuCache;
use TheCodingMachine\GraphQLite\Http\Psr15GraphQLMiddlewareBuilder;
use TheCodingMachine\GraphQLite\SchemaFactory;
use Zend\Stratigility\MiddlewarePipe;

// Picotainer is a minimalist PSR-11 container.
return new Picotainer([
MiddlewarePipe::class => function(ContainerInterface $container) {
$pipe = new MiddlewarePipe();
return $pipe;
// The WebonyxGraphqlMiddleware is a PSR-15 compatible
// middleware that exposes Webonyx schemas.
WebonyxGraphqlMiddleware::class => function(ContainerInterface $container) {
$builder = new Psr15GraphQLMiddlewareBuilder($container->get(Schema::class));
return $builder->createMiddleware();
CacheInterface::class => function() {
return new ApcuCache();
Schema::class => function(ContainerInterface $container) {
// The magic happens here. We create a schema using GraphQLite SchemaFactory.
$factory = new SchemaFactory($container->get(CacheInterface::class), $container);
return $factory->createSchema();

Now, we need to add a first query and therefore create a controller. The application will look into the App\Controllers namespace for GraphQLite controllers.

It assumes that the container has an entry whose name is the controller's fully qualified class name.


namespace App\Controllers;

use TheCodingMachine\GraphQLite\Annotations\Query;

class MyController
public function hello(string $name): string
return 'Hello '.$name;


use App\Controllers\MyController;

return new Picotainer([
// ...

// We declare the controller in the container.
MyController::class => function() {
return new MyController();

And we are done! You can now test your query using your favorite GraphQL client.
