🚀 Safe Actions State – The Ultimate Next.js Server & Client Action Management Tool

A lightweight, type-safe utility for Next.js server & client actions with built-in authentication and RBAC(role based access control) checks, Zod validation, auto retries if server action fails, and real-time toast feedback out of the box. Just write your DB logic & Zod schema, we handle zod validation, authentication, RBAC authorization, error handling, retries & UI feedback seamlessly. No extra code from your side, just focus on your business logic & DB interaction only! 🚀

📌 Why Use Safe Actions State?

As a developer, i know we hate writing repetitive code for every Server Action. Every server action requires:

Authentication verification
Role-based access control (RBAC)
Data validation with Zod
Retry logic for network failures
Real-time toast notifications for user feedback
State management for UI updates

Doing this manually for every action is repetitive, time-consuming, and prone to errors. Wouldn't it be great if all this was handled automatically?

Safe Actions State automates all of it, so you can:

✅ Write 84% less code for each Server Action 🚀
✅ Ship features 5x faster ⚡
✅ Eliminate boilerplate 🎯
✅ Improve error handling & resilience 🛠️
✅ Enhance UX with real-time toast notifications out of the box 🔥
✅ Handle retries for Server Actions upon faillure out of the box 🔄

With Safe Action State, you get:

✅ Automatic retries (configurable) to prevent failures due to transient issues
✅ Built-in authentication & RBAC checks to prevent unauthorized access
✅ Zod validation & error handling with structured field errors
✅ Abortable requests for performance optimization
✅ Live toast notifications for real-time status updates
✅ A clean React hook (useSafeAction) to manage UI state

How Much Time Does Safe Action State Save?

Let's break it down with real numbers:

A typical 1st server action(LEFT GIF) requires ~180-200 lines of boilerplate.
If you have reusable code then the next server actions(RIGHT GIF) requires ~60-70 lines of boilerplate.
Manually handling validation, errors, and retries takes 15-20 minutes per action.
Using SafeAction reduces that to just ~10 lines, saving ~84% of keystrokes.
Across a project with 50 API actions, that's 15+ hours of development time saved.

🚀 Features at a Glance

🔄 1. Automatic Retries & Fault Tolerance

Retries failed requests up to 3 times (configurable) to handle transient network issues.
📊 Reduces request failures by 40-60%, boosting app reliability.

🔐 2. Automated Authentication & RBAC

📦 Installation & Setup Guide for Next.js

`pre-requisite` Step 0: Next.js project with auth.js setup (for now only auth.js is supported but will be extended to all other auth providers soon)

NOTE: Follow the official documentation for auth.js setup, below i am giving code for role setup to make things simple

// src/auth.ts
import NextAuth from "next-auth";
import GitHub from "next-auth/providers/github";

declare module "next-auth" {
  interface Session {
    user: { role?: string };
  }
}

export const { handlers, signIn, signOut, auth } = NextAuth({
  providers: [GitHub],
  callbacks: {
    async session({ session }) {
      session.user.role = "admin"; // hardcoding role for testing purpose only
      return session;
    },
  },
  secret: process.env.AUTH_SECRET,
});

Step 1: Install the package. Supports Bun, NPM, Yarn, PNPM

# With Bun
bun add safe-actions-state

# With NPM
npm install safe-actions-state

# With Yarn
yarn add safe-actions-state

# With PNPM
pnpm add safe-actions-state

Step 2: Install the dependencies

npm install zod zod-error sonner

Step 3: Setup a API route src/app/api/safe-actions-state/route.ts

// src/app/api/safe-actions-state/route.ts
import { auth } from "@/auth"; // adjust this import path as per your project structure
import { NextRequest, NextResponse } from "next/server";
import { SessionObject } from "safe-actions-state";

export const GET = async (req: NextRequest) => {
  const session = await auth();
  const authenticated = !!session && !!session?.user;
  const payload: SessionObject = { authenticated, role: session?.user?.role };
  return NextResponse.json(payload);
};

Step 4: Setup `sonner`

// src/app/layout.tsx
import { Toaster } from "sonner";

export default function RootLayout({
  children,
}: Readonly<{ children: React.ReactNode }>) {
  return (
    <html lang="en">
      <body>
        {children}
        <Toaster position="top-center" />
      </body>
    </html>
  );
}

Step 5: Setup Environment variables

// .env.local
NEXT_PUBLIC_BASE_URL = http://localhost:3000;
SAFE_ACTIONS_STATE_ROUTE = safe-actions-state;
AUTH_SECRET = your-secret-key

🚀 How It Works

🔹 Server-Side Actions `createSafeAction`

Creates a server-side action with authentication, role-based access, zod validation and retry logic.

"use server";
import { createSafeAction } from "safe-actions-state";
import { z } from "zod";

const postSchema = z.object({
  title: z.string().min(1),
  content: z.string().min(1),
});

const postHandler = async (args: z.infer<typeof postSchema>) => {
  // only DB interaction logic goes here & nothing else, WE HANDLE EVERYTHING ELSE OUT OF THE BOX FOR YOU!
  await new Promise((resolve) => setTimeout(resolve, 3000));
  return { data: { title: args.title, content: args.content, id: "123" } };
};

export const SafeServerAction = createSafeAction({
  action: { withInputs: true, handler: postHandler, schema: postSchema },
  actionType: { isPrivate: true, allowedRoles: ["admin", "founder"] }, // TODO: Change roles based on your project
});

Parameters

Name	Type	Description
`action`	`Action<TInput, TOutput>`	Object containing the handler function and schema for input validation
`action.handler`	`(validatedData?) => Promise<ActionState>`	Function responsible for DB interaction and business logic
`action.schema`	`z.Schema<T>`	(Optional if server action has no input arguments) zod validation schema.
`actionType`	`ActionType`	Object specifying the access control configuration
`actionType.isPrivate`	`boolean`	Whether the action requires authentication
`actionType.allowedRoles`	`string[]`	(Optional) Allowed roles for accessing the action. If not specified then all authenticated users are allowed to consume the action.

📝 NOTE:
AbortController and withRetry are fully managed internally you don't need to handle them manually! Actions are automatically retried upon failure and can be canceled effortlessly. useSafeAction exposes abortAction method to abort the server action.

Returns

ActionState<TInput, TOutput> - Returns either data, error, or fieldErrors.

🔹 Client-Side Hook `useSafeAction`

A React hook to execute Safe Actions State from the client with real-time status tracking.
