Express Slow Down

Basic rate-limiting middleware for Express that slows down responses rather than blocking them outright. Current stable version is 3.1.0, released as part of the express-rate-limit ecosystem. It is built on top of express-rate-limit and uses its stores, providing a familiar API for slowing repeated requests. Key differentiator: it delays requests after a threshold instead of rejecting them, making it suitable for public API endpoints where gradual throttling is preferred over hard blocks. Requires Node >= 16 and Express 4/5. Ships TypeScript types, supports ESM and CJS, and is actively maintained.
