Prompting Playbook for Next.js

• Always specify whether you want App Router or Pages Router patterns when prompting for Next.js code
• Mention 'Server Component' or 'Client Component' explicitly so AI places the 'use client' directive correctly
• Include your data layer (Prisma, Drizzle, raw SQL) in prompts so AI generates compatible database queries in Server Actions
• Specify 'with loading.tsx and error.tsx' when requesting page routes to get complete error and loading state handling
• When asking for authentication, mention your provider (NextAuth.js, Clerk, Supabase Auth) for framework-specific integration code

Patterns AI Should Follow in Next.js

• File-based route modules with co-located loading.tsx, error.tsx, and not-found.tsx boundaries
• Server Actions with useFormState for progressive enhancement and Zod validation
• Dynamic metadata generation with generateMetadata for SEO-optimized pages
• Middleware-based authentication guards with redirect chains and cookie handling
• Parallel data fetching in Server Components using Promise.all with proper Suspense boundaries
• Route handlers (route.ts) for webhook endpoints, file uploads, and streaming responses

Server Action with Form Validation

A practical Next.js App Router pattern combining Server Actions with Zod validation and proper error handling.

// app/contacts/actions.ts
'use server';

import { z } from 'zod';
import { revalidatePath } from 'next/cache';
import { redirect } from 'next/navigation';
import { db } from '@/lib/db';

const ContactSchema = z.object({
  name: z.string().min(2, 'Name must be at least 2 characters'),
  email: z.string().email('Invalid email address'),
  message: z.string().min(10, 'Message must be at least 10 characters'),
});

export type FormState = {
  errors?: Record<string, string[]>;
  message?: string;
};

export async function createContact(
  prevState: FormState,
  formData: FormData
): Promise<FormState> {
  const parsed = ContactSchema.safeParse({
    name: formData.get('name'),
    email: formData.get('email'),
    message: formData.get('message'),
  });

  if (!parsed.success) {
    return { errors: parsed.error.flatten().fieldErrors };
  }

  await db.contact.create({ data: parsed.data });
  revalidatePath('/contacts');
  redirect('/contacts/thank-you');
}
