How do I implement a secure Next.js Server Action with Zod validation in React 19?

Here is a production-ready, type-safe Next.js Server Action following Tech Dastak engineering standards. It parses input strictly, handles field errors, and executes within an isolated server environment:

code-output.ts

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

import { z } from 'zod';

const InquirySchema = z.object({
  fullName: z.string().min(2, 'Name is required'),
  email: z.string().email('Invalid email address'),
  query: z.string().min(10, 'Please provide more details'),
});

export async function submitInquiry(prevState: unknown, formData: FormData) {
  const parsed = InquirySchema.safeParse(Object.fromEntries(formData));

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

  // Zyan Queue Event Dispatch
  await fetch('https://api.techdastak.com/v1/inquiries', {
    method: 'POST',
    body: JSON.stringify(parsed.data),
  });

  return { success: true, message: 'Inquiry registered.' };
}
