README

Integrates webonyx/graphql-php with PHPNomad's GraphQL layer. Provides the concrete GraphQLStrategy that phpnomad/graphql declares as an abstraction, so applications can serve GraphQL queries through the webonyx engine without binding their resolvers to it.

Installation

composer require phpnomad/webonyx-integration

What This Provides

• WebonyxGraphQLStrategy implements GraphQLStrategy from phpnomad/graphql. It stitches together SDL fragments and resolver maps contributed by registered TypeDefinitions, builds one webonyx Schema, and executes queries through GraphQL::executeQuery().
• Resolver classes are resolved out of a phpnomad/di InstanceProvider, so a FieldResolver can depend on datastores, services, or any other bound class through normal constructor injection. The schema is built lazily on the first execute() call and rebuilt when a new type definition is registered.

Requirements

• PHP 8.2+
• phpnomad/graphql
• phpnomad/di
• webonyx/graphql-php ^15.0

Usage

Bind WebonyxGraphQLStrategy to the GraphQLStrategy interface in your container, then register a TypeDefinition for each slice of your schema.

<?php

use PHPNomad\GraphQL\Interfaces\FieldResolver;
use PHPNomad\GraphQL\Interfaces\GraphQLStrategy;
use PHPNomad\GraphQL\Interfaces\ResolverContext;
use PHPNomad\GraphQL\Interfaces\TypeDefinition;
use PHPNomad\GraphQL\Webonyx\Strategies\WebonyxGraphQLStrategy;

$container->bind(GraphQLStrategy::class, WebonyxGraphQLStrategy::class);

class PostSchema implements TypeDefinition
{
    public function getSdl(): string
    {
        return <<<SDL
            type Post { id: ID! title: String! }
            extend type Query { posts: [Post!]! }
        SDL;
    }

    public function getResolvers(): array
    {
        return [
            'Query' => ['posts' => PostsQueryResolver::class],
        ];
    }
}

class PostsQueryResolver implements FieldResolver
{
    public function __construct(private readonly PostRepository $posts)
    {
    }

    public function resolve(mixed $rootValue, array $args, ResolverContext $context): mixed
    {
        return $this->posts->all();
    }
}

$strategy = $container->get(GraphQLStrategy::class);
$strategy->registerTypeDefinition(fn() => new PostSchema());

/** @var ResolverContext $context */
$result = $strategy->execute('{ posts { id title } }', [], $context);

Because resolvers are referenced by class name and instantiated through the container, their constructor dependencies wire through the same DI bindings as the rest of the application.
