This example uses lru-cache
to implement a simple rate limiter for API routes (Serverless Functions).
Demo: https://nextjs-rate-limit.vercel.app/
curl http://localhost:3000/api/user -I
HTTP/1.1 200 OK
X-RateLimit-Limit: 10
X-RateLimit-Remaining: 9
curl http://localhost:3000/api/user -I
HTTP/1.1 429 Too Many Requests
X-RateLimit-Limit: 10
X-RateLimit-Remaining: 0
