AI Architecture Guide

This blueprint outlines a robust integration between Next.js 15 (App Router) and a distributed Redis layer using the 2026 LTS '@upstash/redis' v4.0.0 SDK. It leverages React 19's 'cache' for request deduplication and Next.js 15 Server Actions for type-safe, atomic mutations in a serverless cloud environment.

8  token: process.env.UPSTASH_REDIS_REST_TOKEN!,
9});
10if (process.env.NODE_ENV !== 'production') globalForRedis.redis = redis;

12export const getGlobalState = cache(async (key: string): Promise<string | null> => {
13  const data = await redis.get<string>(key);
14  return data;
15});

17export async function updateStateAction(key: string, value: string) {
18  'use server';
19  await redis.set(key, value, { ex: 3600 });
