README

LimitShield is a Laravel middleware package designed to efficiently manage and enforce API rate limiting. It offers customizable rate limits, supports IP-based and user-based limiting, integrates seamlessly with Redis for distributed rate limiting, and provides flexibility in crafting responses for rate limit breaches.

Features

• Configurable rate limits
• IP-based and user-based limiting
• Redis integration for distributed rate limiting
• Customizable responses for rate limit breaches

Installation

Requirements

• PHP ^7.4|^8.0
• Laravel ^8.0|^9.0|^10.0|^11.0
• Redis (for distributed rate limiting)

Step-by-Step Installation

1. Require the Package

   Add LimitShield to your Laravel project using Composer:

   composer require generalfocus/limitshield:*

2. Publish Configuration

   Publish the configuration file to customize the settings:

   php artisan vendor:publish --provider="GeneralFocus\LimitShield\Providers\PackageServiceProvider" --tag="config"

3. Configure Middleware

   Add the RateLimitMiddleware to your HTTP kernel. Edit app/Http/Kernel.php:

   protected $routeMiddleware = [
       // Other middleware
       'rate.limit' => \GeneralFocus\LimitShield\Http\Middleware\RateLimitMiddleware::class,
   ];

Usage

Applying Middleware to Routes

You can apply the rate limit middleware to specific routes or route groups:

use Illuminate\Support\Facades\Route;

Route::middleware('rate.limit')->group(function () {
    Route::get('/api/resource', 'ApiResourceController@index');
});

Alternatively, you can apply the middleware directly in route definitions:

use Illuminate\Support\Facades\Route;

Route::get('/api/resource', 'ApiResourceController@index')->middleware('rate.limit:limit=100,duration=60');

Configuring Limits

Edit the config/limitshield.php file to set your desired rate limits and other configurations:

return [
    'limits' => [
        'global' => [
            'enabled' => true,
            'max_requests' => 100,
            'decay_minutes' => 1,
        ],
        'ip' => [
            'enabled' => true,
            'max_requests' => 50,
            'decay_minutes' => 1,
        ],
        'user' => [
            'enabled' => true,
            'max_requests' => 200,
            'decay_minutes' => 1,
        ],
    ],
    'redis' => [
        'connection' => 'default',
    ],
    'response' => [
        'message' => 'Too many requests, please try again later.',
        'retry_after' => 'Retry-After',
    ],
];
