Quick Start

Install the SDK and connect to Redis.
Create a rate limiter and apply it to incoming operations.

Example:

import { Ratelimit } from "@upstash/ratelimit";
import { Redis } from "@upstash/redis";

const redis = new Redis({ url: "<url>", token: "<token>" });
const limiter = new Ratelimit({ redis, limiter: Ratelimit.slidingWindow(5, "10s") });

const { success } = await limiter.limit("user-id");
if (!success) {
  // throttled
}
