Netmex Response Bundle

This Symfony bundle allows you to handle API responses using custom response classes. It provides a ResponseInterface to standardize how your application manages its responses, making it easy to handle and customize API output and error handling.

Installation

composer require netmex/response

Usage

Implement the Netmex\Response\ResponseInterface in your custom response class.

When you implement the ResponseInterface, you need to define the two methods toResponse and onError.

toResponse(Request $request): Response This method is responsible for converting your data into a valid Symfony Response object (e.g., JsonResponse or any other type based on your needs). It is used for handling successful API responses.

onError(HttpException $error): Response This method is called when an error occurs (for example, when an exception is thrown). It allows you to handle error responses and return custom error messages or formats.

Example Response Class

<?php

namespace App\Response;

use Netmex\Response\ResponseInterface;
use Symfony\Component\HttpFoundation\JsonResponse;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpKernel\Exception\HttpException;

class MyCustomResponse implements ResponseInterface
{
    public function __construct(private array $data) {}

    public function toResponse(Request $request): JsonResponse
    {
        return new JsonResponse($this->data);
    }

    public function onError(HttpException $e): JsonResponse
    {
        return new JsonResponse([
            'error' => $e->getMessage(),
        ], 500);
    }
}

Controller

In your controller, simply return your custom response:

<?php

namespace App\Controller;

use App\Response\CustomResponse;
use Symfony\Component\Routing\Annotation\Route;

class ExampleController
{
    #[Route('/example', name: 'app_example')]
    public function index(): CustomResponse
    {
        $data = ['foo' => 'bar'];
        return new CustomResponse($data);
    }
}
