Server Action (2026 Patterns)
actions.ts
form.tsx
"use server";

import { z } from "zod";

export async function submitForm(prevState: any, formData: FormData) {
  const validatedFields = schema.safeParse({
    email: formData.get("email"),
    password: formData.get("password"),
  });

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

  // Perform database logic here
  await new Promise(res => setTimeout(res, 1000)); 

  return { success: true };
}

// --- Client Component ---

import { useActionState } from "react";
import { useFormStatus } from "react-dom";
import { submitForm } from "./actions";

export default function MyForm() {
  const [state, action] = useActionState(submitForm, null);

      <div>
        <label className="block text-sm font-medium mb-1">Password</label>
        <input 
          name="password" 
          type="password" 
          className="w-full border p-2 rounded" 
        />
        {state?.error?.password && (
          <p className="text-red-500 text-xs mt-1">{state.error.password[0]}</p>
        )}
      </div>
      
      <SubmitButton />
      {state?.success && <p className="text-green-500">Form submitted!</p>}
    </form>
  );
}

function SubmitButton() {
  const { pending } = useFormStatus();

      {pending ? "Submitting..." : "Submit"}
    </button>
  );
}

Security & Validation

This tool generates Zod validation that runs purely on the server. This prevents malicious data injection even if the UI is bypassed. It uses the new safeParse pattern recommended for React 19 Actions.

Zero-Runtime Forms

By leveraging useActionState and useFormStatus, your forms work without huge client-side libraries. They handle loading states and error reporting natively through the Next.js App Router.

React 19 Form & Server Action Generator — The Modern DX Workbench

React 19 and Next.js 15 have fundamentally changed how forms are built. The era of heavy client-side form libraries is ending, replaced by native **Server Actions** and the **useActionState** hook. However, the boilerplate required to handle validation, loading states, and error feedback can be overwhelming.

The **React 19 Form Generator** is designed to provide clean, idiomatic boilerplate that follows 2026 industry standards for type-safe server-side transitions.

⚡ Why Transition to React 19 Form Actions?

The shift from onSubmit handlers to formAction provides several massive advantages for your application:

1. **Progressive Enhancement**: Forms can work even before the JavaScript bundle has fully hydrated, ensuring your site is accessible and fast.

2. **Reduced Bundle Size**: By moving validation logic to the server via Server Actions, you reduce the amount of code sent to the client.

3. **Secure by Design**: Validation happens on the server using Zod, preventing malicious bypasses that are common with client-only validation.

4. **Native State Management**: React's useActionState provides a built-in way to handle response data and validation errors without complex state libraries.

🛠️ What This Tool Generates

- **Zod Validation Schema**: A robust schema for server-side parsing.

- **Server Action (actions.ts)**: A fully typed "use server" function with error-flattening and simulated latency.

- **Client Component (form.tsx)**: A sleek UI using useActionState for error reporting and useFormStatus for pending states.

🚀 How to Build your Form Action

1. **Define your Fields**: Add inputs, choose their types (email, password, etc.), and set them as required.

2. **Configure Identifiers**: Ensure the names match your database or API parameters.

3. **Review the Code**: Inspect the side-by-side preview of the Action and the Component.

4. **Copy & Deploy**: Drop the files into your Next.js project and start building.

🔒 Privacy-First Engineering

Like all tools on the DevUtility Hub, the React 19 Form Generator is **100% Client-Side**. No code, field names, or validation logic is ever sent to our servers. Your application architecture remains entirely private.

Zero-Knowledge Execution & Edge Architecture

Unlike traditional monolithic developer utilities, DevUtility Hub operates entirely on a Zero-Knowledge architectural framework. When utilizing the React 19 Form & Server Action Generator, all computational workload is completely shifted to your local execution environment via WebAssembly (Wasm) and your browser's native JavaScript engine (such as V8 or SpiderMonkey).

Why Local Workloads Matter

Transmitting proprietary JSON objects, sensitive source code, or unencrypted text strings to an unknown third-party server introduces critical security vulnerabilities. By executing the React 19 Form & Server Action Generator securely within the isolated sandbox of your Document Object Model (DOM), we structurally guarantee strict compliance with major data protection regulations like GDPR, CCPA, and HIPAA. We do not ingest, log, or telemetry your text payloads. Your local RAM serves as the absolute boundary.

Network-Free Performance

Furthermore, by completely eliminating asynchronous HTTP POST payloads to a centralized cloud infrastructure, we guarantee effectively zero latency. The React 19 Form & Server Action Generator provides instant execution without arbitrary rate limits, artificial file size constraints, or server timeouts. Our global edge network serves the application wrapper, while your local machine handles the heavy lifting.
