Integration doctrine to codeigniter 4

Maybe like this:

app\Libraries\Doctrine.php

PHP Code:

<?php namespace App\Libraries;

use Doctrine\ORM\EntityManager;
use Doctrine\ORM\Tools\Setup;

class Doctrine
{
    public $em = null;

    public function __construct()
    {
        $dbConfig = config('Config\Database');
        $db = $dbConfig->{$dbConfig->defaultGroup};

        $isDevMode = ENVIRONMENT !== 'production';
        $proxyDir = null;
        $cache = null;
        $useSimpleAnnotationReader = false;

        $config = Setup::createAnnotationMetadataConfiguration(
            [APPPATH . 'Entities'],
            $isDevMode,
            $proxyDir,
            $cache,
            $useSimpleAnnotationReader
        );

        $connection = [
            'driver'   => $db['DBDriver'] === 'MySQLi' ? 'mysqli' : 'pdo_mysql',
            'user'     => $db['username'],
            'password' => $db['password'],
            'host'     => $db['hostname'],
            'dbname'   => $db['database'],
            'charset'  => $db['charset'],
        ];

        $this->em = EntityManager::create($connection, $config);
    }
} 


cli-config.php (folder root project)

PHP Code:

<?php
use App\Libraries\Doctrine;
use Doctrine\ORM\Tools\Console\ConsoleRunner;

error_reporting(E_ALL);

$pathsPath = './app/Config/Paths.php';

require $pathsPath;
$paths = new Config\Paths();

// Location of the framework bootstrap file.
$app = require rtrim($paths->systemDirectory, '/ ') . '/bootstrap.php';
$doctrine = new Doctrine();

return ConsoleRunner::createHelperSet($doctrine->em); 


and now you can exec command 

Code:

vendor/bin/doctrine
