Features

🎨 Beautiful Landing Page

Every project comes with a stunning, responsive landing page that displays API status in real-time with automatic health checks.

Dark theme with purple accents • Real-time status monitoring • Link to API docs

📚 Scalar API Documentation

Forget Swagger UI—your API ships with Scalar, a modern, beautiful API documentation interface.

• Dark mode by default
• Interactive API testing
• Clean, developer-friendly design

Access at: http://localhost:8000/docs

⚙️ Pydantic Settings

Type-safe configuration management with automatic environment variable loading:

from app.core.config import settings

print(settings.TITLE)        # Your project name
print(settings.DEBUG)        # True/False
print(settings.PORT)         # 8000

🔄 Health Check Endpoint

Built-in health monitoring at /health:

{ "status": "ok" }

---

Running Your Project

After scaffolding, navigate to your project and run:

cd my-project

# Activate virtual environment
# Windows:
.venv\Scripts\activate
# Linux/macOS:
source .venv/bin/activate

# Start development server (with hot reload)
run_dev_server

# Or run directly with uvicorn
uvicorn app.main:app --reload --host 0.0.0.0 --port 8000

Then open:

• Landing Page: http://localhost:8000
• API Docs: http://localhost:8000/docs
• Health Check: http://localhost:8000/health

---

Included Dependencies

Your scaffolded project comes with these essential packages pre-installed:

Package	Purpose
fastapi	High-performance web framework
uvicorn	Lightning-fast ASGI server
pydantic-settings	Type-safe configuration management
python-dotenv	Environment variable loading
scalar-fastapi	Modern API documentation
jinja2	Template rendering
email-validator	Email validation support
tzdata	Timezone data
pytest	Testing framework (dev)

---

Environment Configuration

The generated .env file contains essential configuration:

TITLE="my-api"
DESCRIPTION="My awesome API"
VERSION="1.0.0"
DEBUG=True
PORT=8000
HOST="0.0.0.0"

All values are automatically loaded via Pydantic Settings and accessible through settings.

Architecture Philosophy

Builders Hut follows a layered architecture pattern for clean, maintainable code:

┌─────────────────────────────────────┐
│            API Routes               │  ← HTTP request/response handling
├─────────────────────────────────────┤
│            Services                 │  ← Business logic
├─────────────────────────────────────┤
│           Repositories              │  ← Data access abstraction
├─────────────────────────────────────┤
│         Database / Models           │  ← Data persistence
└─────────────────────────────────────┘

• API Layer — Handles HTTP requests, validation, and responses
• Service Layer — Contains business logic, orchestrates operations
• Repository Layer — Abstracts database access, enables testing
• Model Layer — Defines data structures and ORM models

---

Examples

Create a Simple CRUD API

After scaffolding, add a new endpoint in app/api/v1/:

# app/api/v1/users.py
from fastapi import APIRouter

router = APIRouter(prefix="/users", tags=["Users"])

@router.get("/")
async def get_users():
    return [{"id": 1, "name": "John"}]

@router.post("/")
async def create_user(name: str):
    return {"id": 2, "name": name}

Register in app/api/__init__.py:

from app.api.common import router as common_router
from app.api.v1.users import router as users_router

__all__ = ["common_router", "users_router"]

Include in app/main.py:

from app.api import common_router, users_router

app.include_router(common_router)
app.include_router(users_router, prefix="/api/v1")

Roadmap

• Logger configuration
• Database setup wizards (PostgreSQL, SQLite, MongoDB)
• hut add command for adding components to existing projects
• Authentication templates (JWT, OAuth)
• Docker & docker-compose generation
• CI/CD pipeline templates
