FAQPage Schema

How do I implement rate limiting in a TypeScript or JavaScript application?▼

Implement rate limiting in TypeScript or JavaScript by instantiating a Ratelimit object with an Upstash Redis client and calling the limit method to gate user actions using algorithms like slidingWindow.

What rate limiting algorithms are available for protecting APIs in JS?▼

Available rate limiting algorithms for protecting APIs include fixed window, sliding window, and token bucket, which can be deployed across single-region and multi-region environments using the Upstash Redis SDK.

Does Upstash rate limiting support multi-region and edge deployments?▼

Upstash rate limiting supports multi-region and edge deployments, providing practical usage examples to throttle user actions and protect resources across various server and edge environments.

Can I apply dynamic limits and deny lists when throttling user actions?▼

You can apply dynamic limits and deny lists when throttling user actions, utilizing SDK features to customize resource protection and manage access control beyond standard rate limiting patterns.

What is the best way to set up a sliding window rate limiter with Redis?▼

The best way to set up a sliding window rate limiter with Redis is to create an Upstash client, instantiate a Ratelimit object specifying the slidingWindow algorithm, and apply it to gate per-identifier requests.
