README

The Rate Limiter component provides a Token Bucket implementation to rate limit input and output in your application.

Getting Started

composer require symfony/rate-limiter
use Symfony\Component\RateLimiter\Storage\InMemoryStorage;
use Symfony\Component\RateLimiter\RateLimiterFactory;

$factory = new RateLimiterFactory([
    'id' => 'login',
    'policy' => 'token_bucket',
    'limit' => 10,
    'rate' => ['interval' => '15 minutes'],
], new InMemoryStorage());

$limiter = $factory->create();

// blocks until 1 token is free to use for this process
$limiter->reserve(1)->wait();
// ... execute the code

// only claims 1 token if it's free at this moment (useful if you plan to skip this process)
if ($limiter->consume(1)->isAccepted()) {
   // ... execute the code
}
