Laravel API Response

Simple Laravel API response wrapper.

---

Installation

1. Install the package through composer:

   $ composer require obiefy/api-response

2. Register the package service provider to the providers array in app.php file:

   Obiefy\API\ApiResponseServiceProvider::class

3. Register the package facade alias to the aliases array in app.php file:

   'API' => Obiefy\API\Facades\API::class,

4. And finally you can publish the config file:

   php artisan vendor:publish --tag=api-response

Note: You could also include "use Obiefy\API\Facades\API;" at the top of the class, but we recommend not to.

Basic usage

There are to ways of utilizing the package: using the facade, or using the helper function. On either way you will get the same result, it is totally up to you.

Facade:

use API;

...

public function index()
{
    $users = User::latest()->take(5)->get();

    return API::response(200, 'Latest 5 Users', $users);
}

Note: If you decide not to register the service provider and the facade, alias then you need to include use Obiefy\API\Facades\API; at the top of the class, but we recommend not to.

Helper function:

public function index()
{
    $users = User::latest()->take(5)->get();

    return api()->response(200, 'Latest 5 Users', $users);
}

Advanced usage

The response() method accepts three mandatory parameters:

• int $status
• string $message
• string | array $data

For example, in the below example we are calling the response() method thru the facade and we are passing the following parameters: 200 as the status code, User list as the message and $users (a collection of users) as the data.

use API;

...

public function index()
{
    $users = User::latest()->take(5)->get();

    return API::response(200, 'Latest 5 Users', $users);
}

This is the result:

{
    "STATUS": 200,
    "MESSAGE": "Latest 5 Users",
    "DATA": [
        {"name": "Obay Adam", ...}
    ]
}

If you need more data other than the defaults STATUS, MESSAGE, and DATA attributes on your json response, you could pass as many parameters as you need after $data. However, we do recommend formating the extra parameters as a $key => $value array.

As you can see in the below example, we are calling the api() helper and we are passing the following parameters: 200 as the status code, User list as the message, $users (a collection of users) as the data, $code as a key value array and $error as another key value array.

public function index()
{
    $users = User::latest()->take(5)->get();
    $code = ['code' => 30566];
    $error = ['error' => 'ERROR-2019-09-14'];

    return api()->response(200, 'Latest 5 Users', $users, $code, $error);
}

This is the result:

{
    "STATUS": 200,
    "MESSAGE": "Latest 5 Users",
    "DATA": [
        {"name": "Obay Adam", ...}
    ],
    "code": 30566,
    "error": "ERROR-2019-09-14"
}

Another way of creating a response is by calling api() method and passing the parameters directly to the helper function. Again, it is up to you how you better want to use it.

Check the below code example.

public function index()
{
    $users = User::latest()->take(5)->get();

    return api(200, 'Latest 5 Users', $users);
}

This is the result:

{
    "STATUS": 200,
    "MESSAGE": "Latest 5 Users",
    "DATA": [
        {"name": "Obay Adam", ...}
    ]
}

Helper functions

The package ships with a group of functions that will help you to speed up your development process. For example, you could call directly api()->ok() if the response was successful, instead of building the response.

function ok()

The ok() function can be used without passing any parameters, it will defaulted the status code to 200 and use the default message from the configuration file.

return api()->ok();

Result:

{
    "STATUS": 200,
    "MESSAGE": "Process is successfully completed",
    "DATA": {}
}

Or you could pass to the function a custom message and the data you need. In this case, as mentioned before, the ok() status code will be defaulted to 200.

$users = User::latest()->take(5)->get();

return api()->ok("User list", $users);

Result:

{
    "STATUS": 200,
    "MESSAGE": "User list",
    "DATA": [
        {"name": "Obay Adam", ...}
    ]
}

function notFound()

The notFound() function, as its name states, should be used for the case when the resource is not found and the status code will be defaulted to 404. You could pass a custom message to this function otherwise it will use the default message from the configuration file.

return api()->notFound();

function validation()

The validation() function can be used on the case of a validation error exist, throwing a 422 status code by default. It accepts two mandatory parameters: a message and an array of errors, and as many extra parameters you need (we recommend a key value array format). If the message is empty, then the default message will be used instead.

return api()->validation('These fields are required.', ['name', 'lastName']);

function error()

The error() function can be used when an internal server error occurs throwing a 500 status code by default. It accepts two mandatory parameters: a message and an array of errors, and as many extra parameters you need (we recommend a key value array format). If the message is empty, then the default message will be used instead.

Configuration

JSON Response Labels

If you need to customize the default messages or the json response labels, you can do it directly on the api.php configuration file.

method	default status code	change code	message
ok()	200	config('api.codes.success)	trans('api-response::messages.success)
notFound()	404	config('api.codes.notfound)	trans('api-response::messages.notfound)
validation()	422	config('api.codes.validation)	trans('api-response::messages.validation)
error()	500	config('api.codes.error)	trans('api-response::messages.error)

Matching Status Codes

By default, all API responses return a 200 OK HTTP status header. If you'd like the status header to match the Response's status, set the matchstatus configuration to true

Include The Count Of Data

You can optionally include the count of the DATA portion of the response, by setting includeDataCount to true in the api.php configuration file. You can also override the label, if desired, by updating the label in thekeys array of the configuration file.

{
    "STATUS": "200",
    "MESSAGE": "User Profile data",
    "DATA": [
        ...
    ],
    "DATACOUNT": 6
}
