Quick Start

1) Create an entry point

Create public/index.php:

<?php
declare(strict_types=1);
require_once __DIR__ . '/../vendor/autoload.php';

use Lumen\JsonRpc\Config\Config;
use Lumen\JsonRpc\Server\JsonRpcServer;

$config = new Config([
    'handlers' => [
        'paths'    => [__DIR__ . '/../handlers'],
        'namespace' => 'App\Handlers\',
    ],
]);

$server = new JsonRpcServer($config);
$server->run();

2) Create a handler

Create handlers/User.php:

<?php
declare(strict_types=1);
namespace App\Handlers;

use Lumen\JsonRpc\Support\RequestContext;

final class User
{
    public function get(RequestContext $context, int $id): array
    {
        return [
            'id'   => $id,
            'name' => 'Example User',
        ];
    }
}

3) Send a request

curl -X POST http://localhost:8000/ \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"user.get","params":{"id":1},"id":1}'

4) Response

{"jsonrpc":"2.0","result":{"id":1,"name":"Example User"},"id":1}

The mental model

No manual method registry. No hidden auto-generated procedures. Just handler.method.
