Create Type-Safe Middleware for API Rate Limiting

middleware rate-limiting generics security
Prompt
Design a generic, type-safe rate limiting middleware for a Nest.js API that supports multiple strategies: per-user, per-IP, and global rate limits. Implement a flexible configuration system using TypeScript generics that allows dynamic thresholds, with built-in support for Redis-based tracking. Include robust error handling and typed configuration interfaces that can be easily extended across different API endpoints.
