💡 Hint

Common Mistakes

Using only one number instead of two separated by a comma.

Swapping the order of numbers (minutes first instead of requests).

The throttle middleware accepts a string like '60,1' which means 60 requests per 1 minute.

medium

Complete the code to create a custom rate limiter named 'uploads' allowing 10 requests per minute.

Laravel

use Illuminate\Support\Facades\RateLimiter;

RateLimiter::for('uploads', function ([1] $request) {
    return Limit::perMinute(10);
});

💡 Hint

Common Mistakes

Using incorrect class names like RequestHandler or HttpRequest.

Not importing the Request class.

The closure receives an instance of Illuminate\Http\Request, so the parameter type is Request.

hard

Fix the error in the code to limit requests by user ID instead of IP address.

Laravel

RateLimiter::for('api', function (Request $request) {
    return Limit::perMinute(100)->by($request->[1]());
});

💡 Hint

Common Mistakes

Using $request->ip() limits by IP, not user.

Using 'user' or 'user_id' as method names causes errors.

To limit by user ID, you call $request->user()->id to get the authenticated user's ID.

4fill in blank

hard

Fill both blanks to create a rate limiter that limits 5 requests per minute per user email.

Laravel

RateLimiter::for('email_limit', function (Request $request) {
    return Limit::perMinute([1])->by($request->user()->[2]);
});

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 10 instead of 5 for the limit.

Using 'id' instead of 'email' for the user property.

The limit is 5 requests per minute, and the key is the user's email.

5fill in blank

hard

Fill all three blanks to define a rate limiter that allows 20 requests per minute per user IP or user ID fallback.

Laravel

RateLimiter::for('complex_limit', function (Request $request) {
    return Limit::perMinute([1])->by($request->ip() ?: $request->user()->[2] ?? $request->[3]());
});

💡 Hint

Common Mistakes

Using 'email' instead of 'id' for user property.

Using wrong method names for IP.

The limit is 20 requests per minute. It tries to identify by IP first, then user ID, then IP method fallback.
