api-response

Simple package to handle response properly in your API. This package uses Fractal and is based on Build APIs You Won't Hate book.

Install

Via Composer

$ composer require ellipsesynergie/api-response

Requirements

The following versions of PHP are supported by this version:

>= PHP 7.4

Install in Laravel

Add this following service provider to your config/app.php file.

EllipseSynergie\ApiResponse\Laravel\ResponseServiceProvider::class

Install in Lumen

Because of the request object change (see reference) you can no longer access Request object properly in Service provider. To be convenient, we have created a middleware to be used for parsing the include parameter.

$app->register('EllipseSynergie\ApiResponse\Laravel\LumenServiceProvider');

$app->middleware([
    'EllipseSynergie\ApiResponse\Laravel\Middleware\ParseInclude'
]);

Install in your favorite framework or vanilla php

This package can be used in any framework or vanilla php. You simply need to extend EllipseSynergie\ApiResponse\AbstractResponse and implement the withArray() method in your custom class. You can take a look at EllipseSynergie\ApiResponse\Laravel\Response::withArray() for an example.

You will also need to instantiate the response class with a fractal manager instance.

// Instantiate the fractal manager
$manager = new \League\Fractal\Manager;

// Set the request scope if you need embed data
$manager->parseIncludes(explode(',', $_GET['include']));

// Instantiate the response object, replace the class name by your custom class
$response = new \EllipseSynergie\ApiResponse\AbstractResponse($manager);

For more options related to the fractal manager, you can take a look at the official Fractal website

Example inside Laravel or Lumen controller

<?php

use EllipseSynergie\ApiResponse\Contracts\Response;

class BookController extends Controller {

    /**
     * @param Response $response
     */
    public function __construct(Response $response)
    {
        $this->response = $response;
    }

    /**
    * Example returning collection
    */
    public function index()
    {
        //Get all books
        $books = Book::all();
    
        // Return a collection of $books
        return $this->response->withCollection($books, new BookTransformer);
    }

    /**

Testing the package

$ phpunit

Testing within Laravel

According to the issue #31, we have found some problem when it's time to test the include query parameter value. If you want to resolve this issue in your test, you must use the trait EllipseSynergie\ApiResponse\Testing\Laravel\AddTestingSupportForInclude. To replace the call method from Illuminate\Foundation\Testing\Concerns\MakesHttpRequests::call
