This package allows you to easily create and validate rate limiting using the fixed window algorithm.

This package makes use of Redis' atomic requests.


You can install the package via composer:

composer require beyondcode/laravel-fixed-window-limiter


You can create a new limiter instance by calling the create method and pass it a CarbonInterval that represents the window of time, that will be used for the limiter. The second argument is the maximum number of requests/attempts that your limiter will accept in that given time frame.

$limiter = FixedWindowLimiter::create(CarbonInterval::second(2), 2);

Running attempts against your limiter

Once your limiter is created, you can perform attempts against it to see if the call is within the usage limits that you specified. Since your limiter can be used for multiple resources, you need to pass the resource that you want to attempt the call for in the attempt method call.


Getting the usage count

When you want to read the number of attempts that were made for a given resource, you may call the getUsage method.

Note: This method will not return the number of attempts, but only the number of successful attempts. Use the getRealUsage method, if you want to see all attempts, including those that were rejected.

$count = $limiter->getUsage('user_1');

Or as mentioned, to get the real usage of all attempts for the resource:

$count = $limiter->getRealUsage('user_1');

Reset the limiter

If you want to reset the attempts for a specific resource, you may call the reset method on the limiter instance. This will reset the TTL to the given time frame and re-allow new attempts.


Additional data

Sometimes you might want to store additional data inside of the resource hash in Redis. You can pass the initial data to the reset method.

$limiter->reset('user_1', [
    'key' => 'value'

In order to retrieve the data, you may use the getAdditionalData method.

$value = $limiter->getAdditionalData('user_1', 'key');
