Type-Safe Next.js Stack using Simple Clean Architecture with MongoDB Template For AI Friendly
A production-ready Todo Application Template built with Next.js 16, implementing enterprise-grade patterns and modern development practices. This template serves as a robust foundation for building scalable full-stack applications with authentication, CRUD operations, and real-time updates.
This template implements an Entity-Based Repository Architecture with strict separation of concerns:

This template follows enterprise-grade design patterns documented in docs/entity-architecture.md.
// Domain Model (strings) interface Todo { id: string; title: string; completed: boolean; userId: string; } // Database Entity (ObjectIds) interface DbTodoEntity { _id: ObjectId; title: string; completed: boolean; userId: ObjectId; } // Repository Interface (domain types) interface ITodoRepository { create(input: TodoCreateData, context: RepositoryContext): Promise<Todo>; updateContent(id: string, input: TodoContentUpdate, userId: string): Promise<void>; updateStatus(id: string, input: TodoStatusUpdate, userId: string): Promise<void>; } // Service Layer (business logic) class TodoService { async createTodo(userId: string, request: CreateTodoRequest): Promise<Todo> { // Business validation and logic const context = createRepositoryContext(userId); return this.todoRepository.create(request, context); } }
Built-in authentication system with Better Auth:
// Client-side import { useSession, signIn, signOut } from '~/lib/auth-client'; function MyComponent() { const { data: session, isPending } = useSession(); if (session?.user) { return <div>Hello, {session.user.name}!</div>; } return <button onClick={() => signIn.email(credentials)}>Sign In</button>; }
interface DbUserEntity extends AuditableDocument { name: string; email: string; emailVerified: boolean; roles: string[]; }
interface DbTodoEntity extends AuditableDocument { title: string; description?: string; completed: boolean; userId: ObjectId; }
All entities include automatic audit fields via Monguard:
createdAt, updatedAt, deletedAtcreatedBy, updatedBy, deletedBy__vbun build
Set these in your production environment:
NODE_ENV="production" MONGODB_URI="mongodb+srv://..." BETTER_AUTH_SECRET="secure-production-secret" NEXT_PUBLIC_BETTER_AUTH_URL="https://yourdomain.com/api/auth"
