How to Rate Limit Per Day In Laravel?

8 minutes read

To rate limit per day in Laravel, you can leverage the RateLimiter facade provided by Laravel.


First, you need to define a new rate limiter in your application by specifying the maximum number of requests allowed per day and the expiration time of the rate limiting.


Then, you can use the "throttle" middleware in your routes to apply the rate limiting logic. This middleware will check if the user has exceeded the maximum number of requests per day and respond with a 429 status code if they have.


You can customize the rate limiting logic by defining your own throttle key based on the user's IP address or user ID to track the requests per user.


By implementing rate limiting per day in Laravel, you can protect your application from excessive usage and prevent abuse of your API endpoints.


How to dynamically adjust the rate limit based on user activity in Laravel?

One way to dynamically adjust the rate limit based on user activity in Laravel is to create a middleware that checks the user's activity and adjusts the rate limit accordingly. Here is an example of how you can implement this:

  1. Create a custom middleware class in your Laravel project. You can do this by running the following command in your terminal:
1
php artisan make:middleware RateLimitMiddleware


  1. Open the newly created RateLimitMiddleware.php file in the app/Http/Middleware directory and add the following code:
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Cache\RateLimiter;

class RateLimitMiddleware
{
    protected $limiter;

    public function __construct(RateLimiter $limiter)
    {
        $this->limiter = $limiter;
    }

    public function handle($request, Closure $next, $maxRequests = 60, $decayMinutes = 1)
    {
        $key = $request->user()->id;

        if ($this->limiter->tooManyAttempts($key, $maxRequests)) {
            return response()->json(['message' => 'Too many requests'], 429);
        }

        $this->limiter->hit($key, $decayMinutes);

        return $next($request);
    }
}


  1. Register the middleware in the $routeMiddleware array in the app/Http/Kernel.php file:
1
2
3
4
protected $routeMiddleware = [
    ...
    'rate_limit' => \App\Http\Middleware\RateLimitMiddleware::class,
];


  1. Apply the middleware to the routes or controllers where you want to dynamically adjust the rate limit based on user activity. You can pass the maxRequests and decayMinutes values to the middleware as parameters, like so:
1
Route::get('dashboard', 'DashboardController@index')->middleware('rate_limit:60,1');


With this setup, the rate limit for each user will be adjusted based on their activity, with the maxRequests and decayMinutes parameters specifying the maximum number of requests allowed within a given time frame. You can modify these values as needed to suit your application's requirements.


How to implement rate limiting in Laravel?

Rate limiting in Laravel can be implemented using Laravel's built-in middleware called "throttle". Throttle middleware allows you to limit the number of requests a user can make to your application within a specific time frame.


Here's how you can implement rate limiting in Laravel:

  1. Open your terminal and run the following command to create a new middleware:
1
php artisan make:middleware RateLimitMiddleware


  1. Open the newly created RateLimitMiddleware file located in the app/Http/Middleware directory. Update the handle method to use the throttle middleware like this:
1
2
3
4
5
6
7
use Illuminate\Routing\Middleware\ThrottleRequests;

public function handle($request, Closure $next)
{
    return $next($request);
}


  1. Register the middleware in the Kernel.php file located in the app/Http directory. Add the following code to the $routeMiddleware array:
1
'ratelimit' => \App\Http\Middleware\RateLimitMiddleware::class,


  1. Now, you can apply the rate limiting to your routes by attaching the middleware to the route definition. For example, to limit users to 60 requests per minute, you can do the following:
1
2
3
Route::middleware('ratelimit:60,1')->group(function () {
    // Your routes here
});


In this example, the first parameter '60' is the maximum number of requests the user can make within the specified time frame (1 minute).


That's it! You have now implemented rate limiting in Laravel using the throttle middleware. Users will be restricted from making more requests than the specified limit within the defined time frame.


How to prevent bots from bypassing rate limiting in Laravel?

There are several ways to prevent bots from bypassing rate limiting in Laravel:

  1. Implement a CAPTCHA: Adding a CAPTCHA to your application can help prevent bots from making too many requests. This can help ensure that only legitimate users are able to access your application.
  2. Use IP blocking: You can block or restrict access to certain IP addresses that are making too many requests in a short period of time. This can help prevent bots from overwhelming your application with requests.
  3. Implement user authentication: By requiring users to create an account and log in before they can access certain features of your application, you can prevent bots from bypassing rate limiting.
  4. Use a service like Cloudflare: Cloudflare offers protection against bots and can help prevent them from bypassing rate limiting measures in your Laravel application.
  5. Monitor and analyze traffic: By monitoring and analyzing traffic to your application, you can identify patterns or anomalies that indicate bot activity. This can help you adjust your rate limiting measures accordingly.


Overall, it's important to continuously monitor and update your rate limiting measures to stay ahead of bots and ensure the security and performance of your Laravel application.


How to implement sliding window rate limiting in Laravel?

To implement sliding window rate limiting in Laravel, you can use middleware to track the number of requests made within a specified time frame and limit the number of requests allowed. Here's a step-by-step guide on how to implement sliding window rate limiting in Laravel:

  1. Create a new middleware for rate limiting: Create a new middleware using the following command:
1
php artisan make:middleware RateLimitMiddleware


  1. Open the RateLimitMiddleware file located in app/Http/Middleware directory and add the following code to track the number of requests made within a sliding window:
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13

<?php

namespace App\Http\Middleware;

use Closure;
use Cache;

class RateLimitMiddleware
{
    public function handle($request, Closure $next)
    {
        $key = 'user:' . $request->ip();
        $requests = Cache::get($key, []);
        $requests[] = time();

        Cache::put($key, $requests, now()->addSeconds(60));

        if (count($requests) > 5) {
            abort(429, 'Too many requests');
        }

        return $next($request);
    }
}


This code will track the number of requests made by each user within a sliding window of 60 seconds and block the user if they exceed 5 requests.

  1. Register the middleware in the app/Http/Kernel.php file under the $routeMiddleware array:
1
2
3
4
protected $routeMiddleware = [
    // Other middlewares
    'rate.limit' => \App\Http\Middleware\RateLimitMiddleware::class,
];


  1. Apply the middleware to the routes you want to rate limit by adding the middleware key 'rate.limit' to the route definition:
1
Route::middleware('rate.limit')->get('/route', 'Controller@method');


  1. You can customize the number of requests allowed and the time frame by adjusting the values in the RateLimitMiddleware middleware.


With these steps, you have successfully implemented sliding window rate limiting in Laravel using middleware. Users will now be limited based on the number of requests they make within a sliding window, preventing abuse of the application's resources.


How to customize the rate limiting rules in Laravel?

To customize the rate limiting rules in Laravel, you can modify the rate limiting middleware in your application. Here is how you can customize the rate limiting rules:

  1. Open the app/Http/Kernel.php file in your Laravel application.
  2. Locate the $middlewareGroups property and find the throttle middleware. This is the middleware responsible for rate limiting.
  3. You can customize the rate limiting rules by passing an array of options to the throttle middleware. The available options are:
  • max: The maximum number of requests allowed in a given number of minutes.
  • decay: The number of minutes before the rate limit counter resets.
  1. You can customize the rate limiting rules for specific routes or route groups by adding the throttle middleware with the desired options to the route definition. For example:
1
2
3
Route::middleware('throttle:5,1')->get('/example', function () {
    return 'You can only make 5 requests per minute to this endpoint.';
});


In the example above, the route /example is limited to 5 requests per minute.

  1. You can also customize the rate limiting rules globally by modifying the mapApiRoutes or mapWebRoutes method in the RouteServiceProvider class. For example:
1
2
3
Route::middleware('throttle:10,1')->group(function () {
    // Define your API routes here
});


In this example, all API routes will be limited to 10 requests per minute.

  1. After customizing the rate limiting rules, don't forget to clear the rate limiting cache using the php artisan route:clear command to apply the changes.


By following these steps, you can customize the rate limiting rules in Laravel to suit your application's requirements.


How to create a custom rate limiting middleware in Laravel?

To create a custom rate limiting middleware in Laravel, follow these steps:

  1. Create a new middleware class by running the following command in your terminal:
1
php artisan make:middleware RateLimitMiddleware


This will create a new middleware class in the app/Http/Middleware directory.

  1. Open the newly created RateLimitMiddleware class and implement the logic for rate limiting. You can use Laravel's built-in RateLimiter class to handle rate limiting. Here's an example implementation:

namespace App\Http\Middleware;

use Closure;
use Illuminate\Cache\RateLimiter;

class RateLimitMiddleware
{
    protected $limiter;

    public function __construct(RateLimiter $limiter)
    {
        $this->limiter = $limiter;
    }

    public function handle($request, Closure $next, $maxAttempts = 60, $decayMinutes = 1)
    {
        $key = $request->ip();

        if ($this->limiter->tooManyAttempts($key, $maxAttempts)) {
            return response()->json(['message' => 'Too many attempts. Please try again later.'], 429);
        }

        $this->limiter->hit($key, $decayMinutes);

        return $next($request);
    }
}


In this example, the middleware checks if the number of requests from the client's IP address has exceeded the $maxAttempts limit within $decayMinutes. If so, it returns a 429 (Too Many Requests) response. Otherwise, it increments the rate limiter and continues to the next middleware or controller.

  1. Register the middleware in your $routeMiddleware array in the app/Http/Kernel.php file:
1
2
3
4
protected $routeMiddleware = [
    // other middleware...
    'rate.limit' => \App\Http\Middleware\RateLimitMiddleware::class,
];


  1. Apply the middleware to your routes or route groups by using the rate.limit middleware key. For example:
1
2
3
Route::group(['middleware' => 'rate.limit'], function () {
    Route::get('/limited-route', 'Controller@action');
});


Now, requests to the /limited-route will be rate-limited according to the logic defined in the RateLimitMiddleware class.
