 1 | ## Motivation
 2 | 
 3 | [![Total Downloads](https://img.shields.io/packagist/dt/inani/laravel-same-request.svg?style=flat-square)]([https://packagist.org/packages/spatie/laravel-rate-limited-job-middleware](https://packagist.org/packages/inani/laravel-same-request))
 4 | 
 5 | This laravel package will allow you to execute a code once in the current request based on the key provided. 
 6 | 
 7 | ## Installation
 8 | 
 9 | ````
10 | composer require inani/laravel-same-request
11 | ````
12 | 
13 | You will(for L5) need to register the service provider in the  ````config/app.php```` .
14 | ````php
15 | return [
16 |        /*
17 |          * Package Service Providers...
18 |          */
19 | 
20 |         /*
21 |          * Application Service Providers...
22 |          */
23 |         App\Providers\AppServiceProvider::class,
24 |         App\Providers\AuthServiceProvider::class,
25 |         // App\Providers\BroadcastServiceProvider::class,
26 |         App\Providers\EventServiceProvider::class,
27 |         App\Providers\RouteServiceProvider::class,
28 |         Inani\UniqueRequest\UniqueRequestServiceProvider::class, // <=== HERE
29 | ];
30 | ````
31 | 
32 | You will need to use the middleware or binding it globally in your  ````app/Http/Kernel.php````
33 | 
34 | ````php
35 | return [
36 |         'api' => [
37 |                 'throttle:120,1',
38 |                 'bindings',
39 |                 PreventCache::class,
40 |                 GetJwtFromCookie::class,
41 |                 AddUniqueIdentifier::class
42 |          ],
43 | ];
44 | ````
45 | 
46 | 
47 | 
48 | ## Usage
49 | 
50 | 
51 | ````php
52 |     for ($i= 0; $i < 2; $i++){
53 |         $greeting = request()->once(function (){
54 |             info('entred once');
55 |             return 'hello';
56 |         }, 'greeting');
57 |     }
58 | 
59 |     $goodbye = request()->once(function (){
60 |         return 'Saynoara';
61 |     }, 'bye');
62 | 
63 |     $goodbye = request()->once(function (){
64 |         return 'ByeBye';
65 |     }, 'bye');
66 | 
67 |     return [$greeting, $goodbye];
