Axtiva Flexible Graphql

Schema first lib for generate php code from graphql sdl to TypeRegistry whom support webonyx/graphql-php with simple integrate to any controller.

TL;DR

Can easy to integrate graphql to any project, all you need is controller. Fast start with example

Features:

• Schema/SDL first code generation (look at example dir)
• Support all features from webonyx/graphql-php
• Executable directives
• Apollo Federation/Federation2 support
• Amphp v3 support for async executions
• Popular framework integration:
  • Symfony axtiva/flexible-graphql-bundle

Setup

Composer install:

composer require axtiva/flexible-graphql-php

Examples:

• Generate models by types in Graphql Schema example/generate_type_models.php
• Generate custom scalar resolver by Graphql Schema example/generate_scalar_resolver.php
• Generate directive resolver by Graphql Schema example/generate_directive_resolver.php
• Generate type field resolver by Graphql Schema example/generate_field_resolver.php
• Create lazy loaded TypeRegistry example/generate_type_registry.php
• Setup graphql request handler with lazy loaded TypeRegistry example/start_graphql_server.php

Demo

Up Dev server for test http Graphql requests:

php -S localhost:8080 example/start_graphql_server.php

Change schema and run example commands

Update TypeRegistry and model classes from schema and resolvers map:

php example/generate_code.php

If you need to make field resolver, then remove AutoGenerationInterface from model CodedCurrencyType

Example:

- final class CodedCurrencyType implements AutoGenerationInterface, NodeInterface, CurrencyInterface
+ final class CodedCurrencyType implements NodeInterface, CurrencyInterface
{
    public string $id;
-   public int $code;
}

and run php example/generate_code.php, after this you will find in example/GraphQL/Resolver/CodedCurrency/CodeResolver.php. this is your field resolver, define him in your psr container like PsrContainerExample in example/start_graphql_server.php:

$container = new PsrContainerExample([
    \Axtiva\FlexibleGraphql\Example\GraphQL\Resolver\Query\AccountResolver::class =>
        new \Axtiva\FlexibleGraphql\Example\GraphQL\Resolver\Query\AccountResolver,
+   \Axtiva\FlexibleGraphql\Example\GraphQL\Resolver\CodedCurrency\CodeResolver::class =>
+       new \Axtiva\FlexibleGraphql\Example\GraphQL\Resolver\CodedCurrency\CodeResolver,
]);

Run demo app php -S localhost:8080 example/start_graphql_server.php and try request CodedCurrency.code field in query

Amphp v3 Async Execution

AmpFutureAdapter bridges Amphp v3 Future objects with the webonyx/graphql-php promise system, enabling fully non-blocking GraphQL execution.

Setup

use Axtiva\FlexibleGraphql\Executor\AmpFutureAdapter;
use GraphQL\Server\ServerConfig;
use GraphQL\Server\StandardServer;
use Amp\Future;

$config = ServerConfig::create()
    // ... schema, root value, etc.
    ->setPromiseAdapter(new AmpFutureAdapter());

$server = new StandardServer($config);
$promise = $server->executePsrRequest($psrRequest);

$response = null;
if ($promise->adoptedPromise instanceof Future) {
    $response = $promise->adoptedPromise->await()->toArray();
}

return new JsonResponse($response);

Notes

• Every field resolver that returns an Amphp Future is automatically wrapped via Amp\async() by the generated TypeRegistry when you use the TypeRegistryGeneratorBuilderAmphp builder.
• amphp/amp is a suggested dependency; add it explicitly when async execution is needed:

composer require amphp/amp:^3
