How to combine front and back?

Question

PHP

The project has a separate front and back. How to combine them correctly? Is this implementation normal?

<?php

namespace App\Controller\API;

use App\Form\LoginType;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\JsonResponse;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Contracts\HttpClient\HttpClientInterface;

class LoginController extends AbstractController
{
    private $client;

    public function __construct(HttpClientInterface $client)
    {
        $this->client = $client;
    }

... // API
    /**
     * @param Request $request
     *
     * @return JsonResponse
     */
    public function loginAction(Request $request): JsonResponse
    {
        $form = $this->createForm(LoginType::class);
        $form->handleRequest($request);

        $username = $this->getUser()->getUsername();

        return new JsonResponse(['name' => $username]);
    }
...
    /**
     * @param Request $request
     * @return array
     * @throws \Symfony\Contracts\HttpClient\Exception\ClientExceptionInterface
     * @throws \Symfony\Contracts\HttpClient\Exception\DecodingExceptionInterface
     * @throws \Symfony\Contracts\HttpClient\Exception\RedirectionExceptionInterface
     * @throws \Symfony\Contracts\HttpClient\Exception\ServerExceptionInterface
     * @throws \Symfony\Contracts\HttpClient\Exception\TransportExceptionInterface
     */
    public function loginAction(Request $request): JsonResponse
    {
        $response = $this->client->request(
            'POST',
            'http://site.loc/api/login/', [
                    'body' => [
                        'login' => $request->request->get('login'),
                        'password' => $request->request->get('pass')
                    ]
                ]
        );

        $content = $response->toArray();

        return new JsonResponse($content);
    }
}

The front and back are combined on the site itself. The front is the client, all request processing is on the back. Everything is interconnected
