SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Centralizes authentication and authorization checks using a Data Access Layer (DAL) pattern to reduce duplication and improve security across NextJS apps.

Core Features & Use Cases

Verifies active sessions via verifySession and redirects unauthenticated users to login.
Provides guard helpers like requireAdmin and requireActiveSubscription for role-based and subscription-based access control.
Demonstrates server actions and page usage patterns with a reusable DAL in NextJS environments.

Quick Start

Import verifySession in server actions and use requireAdmin or requireActiveSubscription on protected routes to enforce access control.

FAQPage Schema

How do I centralize authentication and authorization checks in NextJS server actions?▼

Centralize authentication in NextJS server actions using a Data Access Layer pattern to verify active sessions and reduce security duplication. Import verifySession into your server actions to guard access and redirect unauthenticated users to login.

What is the best way to enforce role-based access control on protected NextJS routes?▼

Enforce role-based access control on protected NextJS routes using reusable guard helpers like requireAdmin. These guards integrate with your DAL to verify user permissions and restrict access to sensitive server actions and page routes.

How do I restrict page access based on a user's subscription status in NextJS?▼

Restrict NextJS page access based on subscription status by applying the requireActiveSubscription guard to your page routes. This helper validates subscription requirements within your DAL and blocks access if the user lacks an active plan.

Does the Data Access Layer pattern work for both page routes and server actions in NextJS?▼

The Data Access Layer pattern works for both page routes and server actions in NextJS, providing reusable guards like verifySession across your application to ensure consistent security and access control without duplicating logic.

How does verifySession handle unauthenticated users in NextJS?▼

verifySession handles unauthenticated users in NextJS by checking for an active session through a cache-backed verification flow. If no valid session exists, it automatically redirects the user to the login page to prevent unauthorized access.

Can I use better-auth with a DAL pattern to manage NextJS authentication?▼

Use better-auth with a DAL pattern to manage NextJS authentication by applying centralized verification flows to server actions. This setup satisfies cache-backed session validation and reusable guards for consistent role and subscription enforcement.
