php - Laravel 5 - Customize JSON response on a Rest API server -

i new on laravel, migrating application slim framework to, indeed, laravel 5. googling haven't find information how customize json response. let's have:

model

<?php  namespace app;  use illuminate\database\eloquent\model;  class user extends model {     protected $visible = [         'username', 'posts',     ];  } 

controller

<?php  namespace app\http\controllers;  use [...]  /* *  *  implicit controller  */ class usercontroller extends controller {     public function getindex()     {         return response()->json(user::all(), 200);     } } 

route

route::controller('users', 'usercontroller'); 

what if want output data in json object like:

{"success": bool, "message": string, "data": array}  // in case 'array' user::all() 

?

does know whether there's library handle kind of stuff? or has addressed in laravel somehow?

n.b. know can write middleware "modify" response, not sure right solution, , painful check middleware whether response should contain error or not.

thank you.

did try

return response()->json([     'success'=>true,      'message'=>'string',      'data'=>user::all() ]); 

?
