Project Structure

Next-Stage follows a well-organized directory structure:

src/
├── app/                # App router routes
│   ├── _components/    # App-specific components
│   └── _styles/        # App-specific styles
├── components/         # UI components
│   ├── layout/         # Layout components
│   └── ui/             # UI components from shadcn/ui
├── types/              # Type definitions including API response types
├── lib/                # Utility functions
└── ...                 # Other directories

Colocation Pattern

Next-Stage implements the colocation pattern for better organization:

  • Page-specific components, actions, and hooks are located within the page directory
  • Cross-cutting, domain-independent components are kept in top-level directories
  • Underscore prefixes (_components, _actions, _hooks) clearly distinguish page-specific directories from route segments

Hono API Integration

The template features a powerful API implementation using Hono:

  • Modular API Structure: APIs are organized by domain using Hono's routing system
  • TypeScript-Safe Endpoints: All API endpoints have corresponding type definitions
  • Validation Middleware: Integrated Zod validation for request data
