Serverless Rate Limiting

Maintaining system availability while preventing misuse is crucial, and rate limiting serves as an effective solution for these challenges, especially in stateless environments like serverless functions. @upstash/ratelimit, a newly released tool available on GitHub, npm, and Deno, offers a rate-limiting solution built on Upstash Serverless Redis, designed for serverless platforms such as Vercel, Cloudflare, Deno, Fastly, and Netlify. It supports three standardized algorithms and provides methods to either reject requests that exceed limits or delay processing until requests can be handled. For single regional databases, a straightforward setup allows for setting request limits, while global replicated rate-limiting can be implemented to enhance user experience by reducing latency through region-specific databases. For further information, users are encouraged to consult the project's README and engage with the community on GitHub, Discord, and Twitter.
