About

This package was created to extend the Laravel Framework response system, and elevate him to the standard described on the {json:api} website[^jsonapi].

The answers besides creating a more friendly and readable formatting also contemplate the control of the Headers according to the last code.

Installation

Use composer do install our package:

composer require ftd-educacao/default-api-response

And call the provider inside your Laravel /config/app.php file:

    'providers' => [
    ...
        /*
         * FTD Default API Response
         */
         FTD\DefaultApiResponse\DefaultApiResponseServiceProvider::class,
    ],

Now it's done and we're ready to go!

How to use

FTD API Response give us 5 new methods:

1. success
2. paginate
3. error
4. custom
5. defaultStatusCode

Every method has a particular way to use, but always easy.

The success method

This method will throw a header status code 200 and put your content inside a data wrapper:

Example:

  public function index()
  {
      return response()->success(App\User::all());
  }

Result:

{
  "data": [
    {
      "id": 1,
      "name": "Rodolfo",
      "email": "rodolfo@ftdapi.com",
      "created_at": null,
      "updated_at": null
    },
    {
      "id": 2,
      "name": "Shirley",
      "email": "shirlei@ftdapi.com",
      "created_at": "2017-06-16 01:02:03",
      "updated_at": null
    }
  ]
}

Example:

  public function show(User $user)
  {
      return response()->success($user);
  }

Result:

{
  "data": {
    "id": 1,
    "name": "Rodolfo",
    "email": "rodolfo@ftdapi.com",
    "created_at": null,
    "updated_at": null
  }
}

The paginate method

This method will throw a header status code 200 and put your content inside a data wrapper, and create another wrapper called meta, for the pagination properties:

Example:

  public function index()
  {
      $users = App\User::paginate(2);
    return response()->paginate($users);
  }

Result:

{
  "meta": {
    "pagination": {
      "current_page": 2,
      "from": 3,
      "last_page": 3,
      "next_page_url": "http://ftdapi.com/api?page=3",
      "path": "http://ftdapi.com/api",
      "per_page": 2,
      "prev_page_url": "http://ftdapi.com/api?page=1",
      "to": 4,
      "total": 6
    }
  },
  "data": [
    {
      "id": 3,
      "name": "Marley",
      "email": "marley@ftdapi.com",
      "created_at": "2017-06-15 00:00:01",
      "updated_at": null
    },
    {
      "id": 4,
      "name": "Steve",
      "email": "steve@ftdapi.com",
      "created_at": "2017-06-16 01:02:03",
      "updated_at": null
    }
  ]
}

The error method

This method will throw a header status code 400 and put your content inside a errors wrapper:

Example:

  //User Custom Request
  public function rules()
  {
    return [
        'name'      => 'required|string|max:255',
        'username'  => 'required|unique:users|string|max:255',
        'password'  => 'required|string|max:255'
    ];
  }

  ...

  public function response(array $errors)
  {
    return response()->error($errors);
  }

Result:

{
  "errors": [
    "Name must be provided.",
    "Username must be provided.",
    "Password must be provided."
  ]
}

Advanced use for the success, paginate and error methods

If you need change the default status code of this methods, you can give a second parameter, like:

  ...
  return response()->success($data, 201);

  ...
  return response()->paginate($data, 206);

  ...
  return response()->error($data, 401);

The custom method

This method is used for who need more control of the entire response:

• The default content is null
• The default header status code is 200
• The default extra headers is null
• The default header content type is 'application/json'

Example:

  public function myCustomMethod()
  {
    return response()->custom(
      $content = [
            "Name" => "Rodolfo",
            "Age"=>13
            ],
      $status = 200,
      $headers = ["X-USER-INFO" => TRUE],
      $headerContentType = 'application/json'
    );
  }

Result: In your header you will see the:

  "X-USER-INFO" : true

or

  "X-USER-INFO" : 1

Depends on which browser you are using.

And, finally, the response body will receive the contents, but without the default data wrapper:

{
  "Name": "Rodolfo",
  "Age": 13
}

If you need to force download of a PDF file, for example, this method is the right way to do it.

The defaultStatusCode method

This method will throw a header status code and depends on which code, put default message content inside a data or errors wrapper:

Example:

  public function store()
  {
    return response()->defaultStatusCode(400);
  }

Result:

{
  "errors": [
    "Bad Request"
  ]
}
