AI Architecture Guide
Implementation of a high-performance bridge between Next.js 15 (React 19) and a distributed data layer via Server Actions and the 2026 Unified AI SDK. This blueprint focuses on utilizing the 'use' hook for streaming data and Server Actions for mutation, ensuring type-safety and low-latency state synchronization across the edge.

1import { createAI } from 'ai/rsc';
2import { z } from 'zod';

4// 1. Definition of the Server Action for Data Mutation
5export async function syncStateAction(payload: { id: string; data: unknown }) {
6 'use server';
7 const schema = z.object({ id: z.string(), data: z.any() });
8 const validated = schema.parse(payload);

10 const response = await fetch(`https://api.internal.v2026/v1/sync/${validated.id}`, {
11 method: 'POST',
12 headers: { 'Content-Type': 'application/json', 'Authorization': `Bearer ${process.env.INTERNAL_SECRET}` },
13 body: JSON.stringify(validated.data),
14 cache: 'no-store'
