Fixed window

Fixed window counting places requests into a time interval and resets the count when that interval expires.

Use it when

Section titled “Use it when”
  • You want the smallest operational and computational cost.
  • Small bursts around a window boundary are acceptable.
  • Your policy is naturally expressed as “N requests per interval.”

Configuration

Section titled “Configuration”
const limiter = createRateLimiter({
  algorithm: Algorithms.FIXED_WINDOW,
  limit: 100,
  windowMs: 60_000,
