Standalone Promise Adapter

This adapter wraps every GraphQL field resolver in a coroutine.

Installation

Swoole Promise Adapter ius bundled with the base Resonance framework, but if you want to use it standalone, without other Resonance features, you can use:

shell
$ composer require distantmagic/graphql-swoole-promise-adapter

Usage

You need to pass it as an adapter argument to GraphQL facade provided by webonyx/graphql-php.

After that all queries will use Swoole's coroutines and will be resolved asynchronously:

php
<?php

use Distantmagic\GraphqlSwoolePromiseAdapter\GraphqlSwoolePromiseAdapter;
use GraphQL\GraphQL as GraphQLFacade;
use GraphQL\Type\Schema;

/**
 * @var Schema $schema
 * @var string $query
 * @var mixed $rootValue
 * @var mixed $context
 * @var null|array<string,mixed> $variableValues
 */
$promise = GraphQLFacade::promiseToExecute(
    new GraphqlSwoolePromiseAdapter(),
    $schema,
    $query,
    $rootValue,
    $context,
    $variableValues,
);

$promise->then(function (mixed $result) {
    // ...
});
