What problem does it solve?
Provides clear, production-ready patterns to implement authentication and authorization in Next.js applications, removing uncertainty about providers, sessions, middleware, and role checks so teams can secure pages and APIs consistently.
Core Features & Use Cases
- NextAuth (Auth.js) configuration with OAuth and credentials providers to enable sign-in flows and session callbacks.
- Middleware-based route protection and JWT verification patterns for server-side and edge protection of pages and API routes.
- Session management strategies including stateless JWTs and database-backed sessions, with examples for refresh, rotation, and cookie configuration.
- Role-based access control and extended types to protect admin/editor areas and enforce authorization in server components and actions.
- Use Case: Protect a dashboard and API endpoints while allowing OAuth sign-in, issuing secure cookies, and enforcing admin-only routes.
Quick Start
Set up NextAuth with a GitHub provider, enable middleware that protects /dashboard and /api/protected, and verify sessions on the server before rendering.
