Rate Limiting

PrismRateLimitMiddleware uses a token bucket algorithm to limit request rates. Clients exceeding the limit receive a 429 Too Many Requests response.

​
Quick Setup

Basic Rate Limiting
await server.use(PrismRateLimitMiddleware(maxRequestsPerMinute: 60))
That’s it — 60 requests per minute per client.

​
Protecting Specific Routes

Apply rate limiting to sensitive endpoints only:
Targeted Rate Limiting
await server.group("/api/auth", middlewares: [
    PrismRateLimitMiddleware(maxRequestsPerMinute: 10)  // Strict for auth
]) { auth in
    auth.post("/login") { request in
        // Login logic
        .json(["token": "abc123"])
    }
}

await server.group("/api", middlewares: [
    PrismRateLimitMiddleware(maxRequestsPerMinute: 100)  // Relaxed for general API
]) { api in
    api.get("/data") { _ in .json(["data": []]) }
}
For more advanced rate limiting with sliding windows, per-user limits, and X-RateLimit headers, see Advanced Rate Limiting.
