Iâ€™m working on a Next.js project with tRPC for my API layer. I want to implement rate limits to prevent abuse and protect the server from potential issues. Can someone guide me on how to set up rate limits effectively for Next.js APIs and tRPC? Any advice or code examples would be greatly appreciated. Thanks in advance!

Is there any other option then using Redis ?

My application doesn't need to scale across multiple instances.

oh i thought you host it on Vercel. if it is self-hosted on a single instance, you can use a global hash map.

Node.js is single thread event loop. so no worries about mutex
