Plain messages and RPC style wrapper around react/child-process. For pooling messengers take a look at wyrihaximus/react-child-process-pool

To install via Composer, use the command below, it will automatically detect the latest version and bind it with ~.

composer require wyrihaximus/react-child-process-messenger 

While this package supports several ways of setting up communication between parent and child the simplest way is to create class implementing WyriHaximus\React\ChildProcess\Messenger\ChildInterface. Up on calling create everything is set up and created to handle supported RPC's and messages.

<?php

use React\EventLoop\LoopInterface;
use WyriHaximus\React\ChildProcess\Messenger\ChildInterface;
use WyriHaximus\React\ChildProcess\Messenger\Messages\Payload;

use function React\Promise\resolve;

final class ExampleChild implements ChildInterface
{
    public static function create(Messenger $messenger, LoopInterface $loop)
    {
        $messenger->registerRpc('example', function (Payload $payload) {
            return resolve($payload->getPayload());
        });
    }
}

On the parent side you only need to call to spawn a child running that class:

MessengerFactory::parentFromClass('ExampleChild', $loop)->then(static function (Messenger $messenger): void {
    $messenger->rpc(/* etc etc */);
});

For both message and RPC examples see the examples directory
