Use Composer to install the package:
$ composer require nilportugues/laravel5-haljson
Step 1: Add the Service Provider
Laravel
Open up config/app.php and add the following line under providers array:
'providers' => [
//...
\NilPortugues\Laravel5\HalJsonSerializer\Laravel5HalJsonSerializerServiceProvider::class,
],Lumen
Open up bootstrap/app.phpand add the following lines before the return $app; statement:
$app->register(\NilPortugues\Laravel5\HalJsonSerializer\Laravel5HalJsonSerializerServiceProvider::class);
$app->configure('haljson');Also, enable Facades by uncommenting:
$app->withFacades();Step 2: Add the mapping
Create a haljson.php file in config/ directory. This file should return an array returning all the class mappings.
Step 3: Usage
For instance, lets say the following object has been fetched from a Repository , lets say PostRepository - this being implemented in Eloquent or whatever your flavour is:
use Acme\Domain\Dummy\Post;
use Acme\Domain\Dummy\ValueObject\PostId;
use Acme\Domain\Dummy\User;
use Acme\Domain\Dummy\ValueObject\UserId;
use Acme\Domain\Dummy\Comment;
use Acme\Domain\Dummy\ValueObject\CommentId;
//$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 bootstrap/haljson.php, that require to use named routes so we can use the route() helper function:
<?php
//bootstrap/haljson.php
return [
[
'class' => 'Acme\Domain\Dummy\Post',
'alias' => 'Message',
'aliased_properties' => [
'author' => 'author',
'title' => 'headline',
'content' => 'body',
],
'hide_properties' => [
],
'id_properties' => [
'postId',
],
'urls' => [
'self' => 'get_post', //named route
'comments' => 'get_post_comments',//named route
],
'curies' => [
'name' => 'example',
'href' => "http://example.com/docs/rels/{rel}",
]
],
[
'class' => 'Acme\Domain\Dummy\ValueObject\PostId',
'alias' => '',
'aliased_properties' => [],
'hide_properties' => [],
'id_properties' => [
'postId',
],
'urls' => [
'self' => 'get_post',//named route
],
'curies' => [
'name' => 'example',
'href' => "http://example.com/docs/rels/{rel}",
]
],
[
'class' => 'Acme\Domain\Dummy\User',
'alias' => '',
'aliased_properties' => [],
'hide_properties' => [],
'id_properties' => [
'userId',
],
'urls' => [
'self' => 'get_user',//named route
'friends' => 'get_user_friends',//named route
'comments' => 'get_user_comments',//named route
],
'curies' => [
'name' => 'example',
'href' => "http://example.com/docs/rels/{rel}",
]
],
[
'class' => 'Acme\Domain\Dummy\ValueObject\UserId',
'alias' => '',
'aliased_properties' => [],
'hide_properties' => [],
'id_properties' => [
'userId',
],
'urls' => [
'self' => 'get_user',//named route
'friends' => 'get_user_friends',//named route
'comments' => 'get_user_comments',//named route
],
'curies' => [
'name' => 'example',
'href' => "http://example.com/docs/rels/{rel}",
]
],
[
'class' => 'Acme\Domain\Dummy\Comment',
'alias' => '',
'aliased_properties' => [],
'hide_properties' => [],
'id_properties' => [
'commentId',
],
'urls' => [
'self' => 'get_comment',//named route
],
'curies' => [
'name' => 'example',
'href' => "http://example.com/docs/rels/{rel}",
]
],
[
'class' => 'Acme\Domain\Dummy\ValueObject\CommentId',
'alias' => '',
'aliased_properties' => [],
'hide_properties' => [],
'id_properties' => [
'commentId',
],
'urls' => [
'self' => 'get_comment',//named route
],
'curies' => [
'name' => 'example',
'href' => "http://example.com/docs/rels/{rel}",
]
],
];The named routes belong to the app/Http/routes.php. Here's a sample for the routes provided mapping:
Laravel
Route::get(
'/docs/rels/{rel}',
['as' => 'get_example_curie_rel', 'uses' => 'ExampleCurieController@getRelAction']
);
Route::get(
'/post/{postId}',
['as' => 'get_post', 'uses' => 'PostController@getPostAction']
);
Route::get(
'/post/{postId}/comments',
['as' => 'get_post_comments', 'uses' => 'CommentsController@getPostCommentsAction']
);
//...Lumen
$app->get(
'/docs/rels/{rel}',
['as' => 'get_example_curie_rel', 'uses' => 'ExampleCurieController@getRelAction']
);
$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 Serializer service as follows:
<?php
namespace App\Http\Controllers;
use Acme\Domain\Dummy\PostRepository;
use NilPortugues\Laravel5\HalJsonSerializer\HalJsonSerializer;
use NilPortugues\Laravel5\HalJsonSerializer\HalJsonResponseTrait;
class PostController extends \Laravel\Lumen\Routing\Controller
{
use HalJsonResponseTrait;
/**
* @var PostRepository
*/
private $postRepository;
/**
* @var HalJsonSerializer
*/
private $serializer;
/**
* @param PostRepository $postRepository
* @param HalJsonSerializer $halJsonSerializer
*/
public function __construct(PostRepository $postRepository, HalJsonSerializer $halJsonSerializer)
{
$this->postRepository = $postRepository;
$this->serializer = $halJsonSerializer;
}
/**
* @param int $postId
*
* @return \Symfony\Component\HttpFoundation\Response
*/
public function getPostAction($postId)
{
$post = $this->postRepository->findById($postId);
/** @var \NilPortugues\Api\HalJson\HalJsonTransformer $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));
}
