About

Package codebot/laravel-response-builder is a simple package for Laravel framework to standardize the structure of JSON responses.

You will find this package helpful if you need your responses to look like this:

{
  "status": true,
  "message": "You got that!",
  "data" : {
    "name": "James Joesph Bulger", 
    "profession": "criminal"
  },
  "errors": []
}

or

{
  "status": false,
  "message": "Something went wrong...",
  "data" : [],
  "errors": {
    "email": [
      "The email field is required."
    ]
  }
}

Installation

composer require codebot/laravel-response-builder:^1

For Laravel 5.4 and versions below add \Rb\Core\RbServiceProvider::class to providers in config/app.php file.

Next run the command below in your console:

php artisan vendor:publish --tag=laravel-response-builder

Requests

Once you published vendor, you should see App\Http\Requests\Rb\RbRequest class. This will be base class for laravel-response-builder's requests.
To generate a request that extends RbRequest, run:

php artisan make:rbrequest YourNewRequest

If you are using Laravel's Validator class, you can use Rb\Core\RbValidator to standardize the structure of failed response.

use \Rb\Core\RbValidator;
use Illuminate\Support\Facades\Validator;

$validator = new Validator($data, $rules); // assuming you have a $validator instance

RbValidator::validate($validator); // throws HttpResponseException or returns boolean true 

RbValidator::validate() method checks if the validation fails and throws Illuminate\Http\Exceptions\HttpResponseException with the standardized json response structure.

Usage

use \Rb\Core\Response;
use \Rb\Core\HttpStatusCode;

$response = new Response();

$response->setStatusCode(HttpStatusCode::OK); // required. If code is 2XX then Response::status field will be "true", otherwise "false"

$response->setMessage('Some inspiring message.'); // null will be returned if no message set

$response->setData($data); // null will be returned if no data set

$response->setErrors($errors); // null will be returned if no error set

$response->getArray(); // will return an array of data set

$response->getResponse(); // will return a json response using Laravel's response() helper 

All setters are fluent, so example above could be written like:

use \Rb\Core\Response;
use \Rb\Core\HttpStatusCode;

$response = new Response();

$response->setStatusCode(HttpStatusCode::OK)
    ->setMessage('Some inspiring message.'); 
    // ...

Package contains HttpStatusCode class with http status codes defined.

use \Rb\Core\HttpStatusCode;

HttpStatusCode::OK; // returns status code 200 (integer)

HttpStatusCode::getMessageByCode(HttpStatusCode::NOT_FOUND); // returns string "Not Found"

HttpStatusCode::getCodeWithMessage(HttpStatusCode::CREATED); // returns string - code and message, e.g. "201 Created"

The Facade

The package contains a facade class in case if you don't want to interact with all of these setters.

use \Rb\Facade\Response;
use \Rb\Core\HttpStatusCode;

return Response::success(
   data: $data,
   message: 'Created List of users.'
);

return Response::error(
   errors: $errors,
   message: 'Invalid input.',
   statusCode: HttpStatusCode::UNPROCESSABLE_ENTITY
);

// Without $data (the $errors parameter is also optional)
return Response::success(message: 'User deleted.');

$data and $errors variables are arrays and are optional.
