## Installation
**Step 1: Download the Bundle**
Open a command console, enter your project directory and execute the
following command to download the latest stable version of this bundle:
```bash
$ composer require nilportugues/haljson-bundle
```
**Step 2: Enable the Bundle**
Then, enable the bundle by adding it to the list of registered bundles
in the `app/AppKernel.php` file of your project:
```php
(new DateTime('2015/07/18 12:13:00'))->format('c'),
'accepted_at' => (new DateTime('2015/07/19 00:00:00'))->format('c'),
]
),
]
);
```
And the series of mapping files required:
```yml
# app/config/serializer/acme_domain_dummy_post.yml
mapping:
class: Acme\Domain\Dummy\Post
alias: Message
aliased_properties:
author: author
title: headline
content: body
hide_properties: []
id_properties:
- postId
urls:
self: get_post ## @Route name
comments: get_post_comments ## @Route name
curies:
name: example
href: http://example.com/docs/rels/{rel}
```
```yml
# app/config/serializer/acme_domain_dummy_value_object_post_id.yml
mapping:
class: Acme\Domain\Dummy\ValueObject\PostId
aliased_properties: []
hide_properties: []
id_properties:
- postId
urls:
self: get_post ## @Route name
curies:

```
```yml
# app/config/serializer/acme_domain_dummy_comment.yml
mapping:

```

hide_properties: []
id_properties:

urls:
self: get_comment ## @Route name
curies:

```
```yml
# app/config/serializer/acme_domain_dummy_user.yml
mapping:

aliased_properties: []
hide_properties: []
id_properties:

```
```yml
# app/config/serializer/acme_domain_dummy_value_object_user_id.yml
mapping:
class: Acme\Domain\Dummy\ValueObject\UserId
aliased_properties: []
hide_properties: []
id_properties:

self: get_user ## @Route name
friends: get_user_friends ## @Route name
comments: get_user_comments ## @Route name
curies:
name: example
href: http://example.com/docs/rels/{rel}
```
## Outputing API Responses
It is really easy, just get an instance of the `HalJsonSerializer` from the **Service Container** and pass the object to its `serialize()` method. Output will be valid JSON-API.
Here's an example of a `Post` object being fetched from a Doctrine repository.
Finally, a helper trait, `HalJsonResponseTrait` is provided to write fully compilant responses wrapping the PSR-7 Response objects provided by the original JSON API Transformer library.
```php
get('doctrine.post_repository')->find($postId);
$serializer = $this->get('nil_portugues.serializer.hal_json_serializer');
/** @var \NilPortugues\Api\Hal\HalTransformer $transformer */
$transformer = $serializer->getTransformer();
$transformer->setSelfUrl($this->generateUrl('get_post', ['postId' => $postId], true));
$transformer->setNextUrl($this->generateUrl('get_post', ['postId' => $postId+1], true));
return $this->response($serializer->serialize($post));
}
}
```
**Output:**
```
HTTP/1.1 200 OK
Cache-Control: private, max-age=0, must-revalidate
Content-type: application/hal+json
```
```json
{
"post_id": 9,
"headline": "Hello World",
"body": "Your first post",
"_embedded": {
"author": {
"user_id": 1,
"name": "Post Author",
"_links": {
"self": {

},
"example:friends": {
"href": "http://example.com/users/1/friends"
},
"example:comments": {
"href": "http://example.com/users/1/comments"
}
}
},

{

}
```
#### Response objects (HalJsonResponseTrait)
The following `HalJsonResponseTrait` methods are provided to return the right headers and HTTP status codes are available:
```php
private function errorResponse($json);
private function resourceCreatedResponse($json);
private function resourceDeletedResponse($json);
private function resourceNotFoundResponse($json);
private function resourcePatchErrorResponse($json);
private function resourcePostErrorResponse($json);
private function resourceProcessingResponse($json);
private function resourceUpdatedResponse($json);
private function response($json);
private function unsupportedActionResponse($json);
```
## Integration with NelmioApiDocBundleBundle
The [NelmioApiDocBundle](https://github.com/nelmio/NelmioApiDocBundle/blob/master/Resources/doc/index.md) is a very well known bundle used to document APIs. Integration with the current bundle is terrible easy.
Here's an example following the `PostContoller::getPostAction()` provided before:
```php
get('doctrine.post_repository')->find($postId);
$serializer = $this->get('nil_portugues.serializer.hal_json_serializer');
/** @var \NilPortugues\Api\Hal\JsonTransformer $transformer */
$transformer = $serializer->getTransformer();
$transformer->setSelfUrl($this->generateUrl('get_post', ['postId' => $postId], true));
$transformer->setNextUrl($this->generateUrl('get_post', ['postId' => $postId+1], true));
return $this->response($serializer->serialize($post));
}
}
```
And the recommended configuration to be added in `app/config/config.yml`
```yml
#app/config/config.yml
nelmio_api_doc:
sandbox:
authentication:
name: access_token
delivery: http
type: basic
custom_endpoint: false
enabled: true
endpoint: ~
accept_type: ~
body_format:
formats: []
default_format: form
request_format:
formats:
json: application/hal+json
method: accept_header
default_format: json
entity_to_choice: false
```
