, (*1)
Compatible with Laravel 5.0, 5.1 & 5.2, (*2)
Installation
Use Composer to install the package:, (*3)
$ composer require nilportugues/laravel5-json
Laravel 5 / Lumen Configuration
Step 1: Add the Service Provider, (*4)
Laravel, (*5)
Open up config/app.php and add the following line under providers array:, (*6)
'providers' => [
//...
\NilPortugues\Laravel5\Json\Laravel5JsonServiceProvider::class,
],
Lumen, (*7)
Open up bootstrap/app.phpand add the following lines before the return $app; statement:, (*8)
$app->register(\NilPortugues\Laravel5\Json\Laravel5JsonServiceProvider::class);
$app->configure('json');
Also, enable Facades by uncommenting:, (*9)
$app->withFacades();
Step 2: Add the mapping, (*10)
Create a json.php file in config/ directory. This file should return an array returning all the class mappings., (*11)
Step 3: Usage, (*12)
For instance, lets say the following object has been fetched from a Repository , lets say PostRepository - this being implemented in Eloquent or whatever your flavour is:, (*13)
use Acme\Domain\Dummy\Post;
use Acme\Domain\Dummy\ValueObject\PostId;
use Acme\Domain\Dummy\User;
use Acme\Domain\Dummy\ValueObject\UserId;
use Acme\Domain\Dummy\Comment;
use Acme\Domain\Dummy\ValueObject\CommentId;
//$postId = 9;
//PostRepository::findById($postId);
$post = new Post(
new PostId(9),
'Hello World',
'Your first post',
new User(
new UserId(1),
'Post Author'
),
[
new Comment(
new CommentId(1000),
'Have no fear, sers, your king is safe.',
new User(new UserId(2), 'Barristan Selmy'),
[
'created_at' => (new \DateTime('2015/07/18 12:13:00'))->format('c'),
'accepted_at' => (new \DateTime('2015/07/19 00:00:00'))->format('c'),
]
),
]
);
And a series of mappings, placed in config/json.php, that require to use named routes so we can use the route() helper function:, (*14)
<?php
//config/json.php
return [
[
'class' => 'Acme\Domain\Dummy\Post',
'alias' => 'Message',
'aliased_properties' => [
'author' => 'author',
'title' => 'headline',
'content' => 'body',
],
'hide_properties' => [
],
'id_properties' => [
'postId',
],
'urls' => [
'self' => ['name' => get_post'], //named route
'comments' => ['name' => 'get_post_comments'], //named route
],
],
[
'class' => 'Acme\Domain\Dummy\ValueObject\PostId',
'alias' => '',
'aliased_properties' => [],
'hide_properties' => [],
'id_properties' => [
'postId',
],
'urls' => [
'self' => ['name' => 'get_post'], //named route
],
],
[
'class' => 'Acme\Domain\Dummy\User',
'alias' => '',
'aliased_properties' => [],
'hide_properties' => [],
'id_properties' => [
'userId',
],
'urls' => [
'self' => ['name' => 'get_user'], //named route
'friends' => ['name' => 'get_user_friends'], //named route
'comments' => ['name' => 'get_user_comments'], //named route
],
],
[
'class' => 'Acme\Domain\Dummy\ValueObject\UserId',
'alias' => '',
'aliased_properties' => [],
'hide_properties' => [],
'id_properties' => [
'userId',
],
'urls' => [
'self' => ['name' => 'get_user'], //named route
'friends' => ['name' => 'get_user_friends'], //named route
'comments' => ['name' => 'get_user_comments'], //named route
],
],
[
'class' => 'Acme\Domain\Dummy\Comment',
'alias' => '',
'aliased_properties' => [],
'hide_properties' => [],
'id_properties' => [
'commentId',
],
'urls' => [
'self' => ['name' => 'get_comment'], //named route
],
],
[
'class' => 'Acme\Domain\Dummy\ValueObject\CommentId',
'alias' => '',
'aliased_properties' => [],
'hide_properties' => [],
'id_properties' => [
'commentId',
],
'urls' => [
'self' => ['name' => 'get_comment'], //named route
],
],
];
The named routes belong to the app/Http/routes.php. Here's a sample for the routes provided mapping:, (*15)
Laravel, (*16)
Route::get(
'/post/{postId}',
['as' => 'get_post', 'uses' => 'PostController@getPostAction']
);
Route::get(
'/post/{postId}/comments',
['as' => 'get_post_comments', 'uses' => 'CommentsController@getPostCommentsAction']
);
//...
Lumen, (*17)
$app->get(
'/post/{postId}',
['as' => 'get_post', 'uses' => 'PostController@getPostAction']
);
$app->get(
'/post/{postId}/comments',
['as' => 'get_post_comments', 'uses' => 'CommentsController@getPostCommentsAction']
);
//...
All of this set up allows you to easily use the JsonSerializer service as follows:, (*18)
<?php
namespace App\Http\Controllers;
use Acme\Domain\Dummy\PostRepository;
use NilPortugues\Laravel5\Json\JsonSerializer;
use NilPortugues\Laravel5\Json\JsonResponseTrait;
class PostController extends \Laravel\Lumen\Routing\Controller
{
use JsonResponseTrait;
/**
* @var PostRepository
*/
protected $postRepository;
/**
* @var JsonSerializer
*/
protected $serializer;
/**
* @param PostRepository $postRepository
* @param JsonSerializer $jsonSerializer
*/
public function __construct(PostRepository $postRepository, JsonSerializer $jsonSerializer)
{
$this->postRepository = $postRepository;
$this->serializer = $jsonSerializer;
}
/**
* @param int $postId
*
* @return \Symfony\Component\HttpFoundation\Response
*/
public function getPostAction($postId)
{
$post = $this->postRepository->findById($postId);
/** @var \NilPortugues\Api\Json\JsonTransformer $transformer */
$transformer = $this->serializer->getTransformer();
$transformer->setSelfUrl(route('get_post', ['postId' => $postId]));
$transformer->setNextUrl(route('get_post', ['postId' => $postId+1]));
return $this->response($this->serializer->serialize($post));
}
}
