Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

@croco/ratelimit-upstash

Upstash Redis와 Lua 스크립트로 분산 rate limiting을 구현하는 패키지입니다.

설치

pnpm add @croco/ratelimit-upstash @croco/ratelimit-core @upstash/redis

사용법

import { Redis } from "@upstash/redis";
import { UpstashSlidingWindowStore } from "@croco/ratelimit-upstash";
import { RateLimiter, createSlidingWindowPolicy } from "@croco/ratelimit-core";

const redis = new Redis({
  url: process.env.UPSTASH_REDIS_REST_URL!,
  token: process.env.UPSTASH_REDIS_REST_TOKEN!,
});

const store = new UpstashSlidingWindowStore({ redis, prefix: "ratelimit" });
const limiter = new RateLimiter(store, ({ ip }) => ip);
const policy = createSlidingWindowPolicy("api", 100, 60_000);

const result = await limiter.check({ ip: "127.0.0.1" }, policy);

API 레퍼런스

| API | 설명 | | ------------------------------- | ----------------------------------------------- | | UpstashSlidingWindowStore | 슬라이딩 윈도우 제한을 수행합니다. | | UpstashTokenBucketStore | 토큰 버킷 제한을 수행합니다. | | UpstashFixedWindowStore | 고정 윈도우 제한을 수행합니다. | | UpstashRateLimitStoreOptions | redisprefix를 받는 공통 옵션 타입입니다. | | InvalidRateLimitPolicyProblem | 저장소와 정책 타입이 맞지 않을 때 발생합니다. |

동작 메모

  • 모든 알고리즘은 Redis Lua 스크립트로 원자성을 보장합니다.
  • 기본 prefix는 저장소별로 ratelimit:sliding, ratelimit:bucket, ratelimit:fixed를 사용합니다.
  • 통계는 메모리 기준으로 allowed, denied, total을 누적합니다.
