commandkitratelimiter.ts

Rate limiter implementation that enforces request limits per key. Supports configurable request limits and time intervals.

Signature
class RateLimiter {
    constructor(maxRequests: number = DEFAULT_MAX_REQUESTS, interval: number = DEFAULT_TIMEOUT, storage: RateLimitStorage = new MemoryRateLimitStorage())
    setStorage(storage: RateLimitStorage) => ;
    getStorage() => RateLimitStorage;
    limit(key: string) => Promise<boolean>;
    getRemaining(key: string) => Promise<number>;
    getResetTime(key: string) => Promise<number>;
    reset(key: string) => Promise<void>;
    getConfig() => Omit<RateLimitOptions, 'storage'>;
}
