How do you implement rate limiting in Laravel APIs?

Implementing Rate Limiting in Laravel APIs

1. Configure Rate Limiting in RouteServiceProvider

Open the app/Providers/RouteServiceProvider.php file and modify the boot method to define your rate limiting rules:

Example

<?php
use Illuminate\Support\Facades\RateLimiter;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Route;

public function boot()
{
    $this->configureRateLimiting();
}

protected function configureRateLimiting()
{
    RateLimiter::for('api', function (Request $request) {
        return Limit::perMinute(60)->by(optional($request->user())->id ?: $request->ip());
    });

    RateLimiter::for('login', function (Request $request) {
        return Limit::perMinute(10)->by($request->ip());
    });
}
?>
  • RateLimiter: Use the RateLimiter facade to create rate limits.
  • Limit: Specify the maximum number of requests allowed (e.g., 60 requests per minute).
  • Keying: Use user ID or IP address for unique identification.

2. Apply Rate Limiting Middleware to Routes

In your routes/api.php, apply the throttle middleware to your API routes:

Example

<?php
use Illuminate\Support\Facades\Route;

Route::middleware(['throttle:api'])->group(function () {
    Route::get('/user', 'UserController@index');
    Route::post('/user', 'UserController@store');
    Route::middleware(['throttle:login'])->post('/login', 'AuthController@login');
    // Other routes...
});
?>
  • Throttle Middleware: Use throttle:api to apply the previously defined rate limit for general routes and throttle:login for specific routes.

3. Handle Rate Limit Exceeded Responses

When a user exceeds the defined rate limit, Laravel automatically responds with a 429 Too Many Requests status code. You can customize this response by publishing the rate limiting configuration:

Example

php artisan vendor:publish --provider="Illuminate\Routing\RoutingServiceProvider"

Then, you can adjust the response in the app/Http/Middleware/ThrottleRequests.php file if needed.

4. Testing Rate Limiting

To test the rate limiting functionality, you can use tools like Postman or automate tests in Laravel to make repeated requests to your API endpoints and verify that the rate limits are enforced correctly.
