Redis is a natural companion for Next.js when you need fast caching, rate limiting, or ephemeral flags. This post shows where Redis fits in a Next.js architecture and how to wire it into Route Handlers and Server Actions without overcomplicating things.
1Explains common Redis use cases in a Next.js project: caching, rate limiting, sessions, and feature flags.
2Shows how to create a shared Redis client in lib/redis.ts and reuse it across handlers.
3Provides a concrete data caching example in an App Router Route Handler with TTL.
4Demonstrates a simple IP-based rate limiter using INCR and EXPIRE in Redis.
5Covers using Redis inside Server Actions and clarifies the difference between Node and Edge runtimes.
