Deploy and Host NextJS 15.5 (Server Actions) with Shadcn on Railway

NextJS 15.5 (Server Actions) with Shadcn is a production-ready Next.js 15.5.4 starter template using the App Router. It features Server Actions for type-safe data mutations, replacing traditional API routes for logic like authentication. The template is built with a Screaming Architecture and styled using beautiful shadcn/ui components with an Amber Minimal theme.

About Hosting NextJS 15.5 (Server Actions) with Shadcn

Hosting this setup involves deploying a full-stack application that heavily relies on Next.js's integrated server-side capabilities. The primary goal is ensuring the Server Actions execute correctly in a production environment. A platform like Railway excels here due to its zero-config deployment: it automatically detects Next.js, installs dependencies, builds the app, and configures the container to run correctly (e.g., binding to 0.0.0.0), including crucial production features like graceful shutdown and built-in health checks (/api/health).

Common Use Cases

• Full-Stack SaaS Boilerplate: Quickly launching a new service with all authentication flows and a professional dashboard.
• Enterprise Web Applications: Building large, maintainable apps using the Screaming Architecture and type-safe data handling via Server Actions.
• Modernizing Legacy Applications: Transitioning from a complex client-server API structure to a simplified, high-performance integrated Next.js setup.

Dependencies for NextJS 15.5 (Server Actions) with Shadcn Hosting

• Next.js (15.5.4)
• React (19.2.0)
• TypeScript (5.9.3)
• shadcn/ui (Latest)
• Zod (4.1.11) for runtime validation

Deployment Dependencies

• Railway Deploy Link
• Project GitHub Repository

Implementation Details

The core Server Actions pattern ensures type-safety and simplicity for form handling:

1. Shared Schema: A single Zod schema is used for client and server validation.
2. Server Action: A function with 'use server' handles logic (e.g., password hashing).
3. Client Form: Uses useFormState and useTransition for state management and action submission.

// Example Server Action
'use server';

import { signupSchema } from '@/features/auth/types/auth.types';

export async function signupAction(
  _prevState: any,
  formData: FormData
): Promise {
  const result = signupSchema.safeParse({ /* ... data extraction */ });

  if (!result.success) {
    return { success: false, message: 'Validation failed' };
  }

  // Business logic (hashing, creating user, etc.)
  return { success: true, message: 'Account created!' };
}
