## 💻 Code Comparison

### Simple Hello World

#### Django
```python
# myproject/settings.py (100+ lines of config)
# myproject/urls.py
from django.urls import path
from . import views

urlpatterns = [
    path('', views.home),
]

# views.py
from django.http import JsonResponse

def home(request):
    return JsonResponse({"message": "Hello"})

# manage.py runserver
```
**Lines:** ~150+  
**Files:** 5+  
**Setup Time:** 10 minutes

---

#### FastAPI
```python
from fastapi import FastAPI

app = FastAPI()

@app.get("/")
async def home():
    return {"message": "Hello"}

# uvicorn main:app --reload
```
**Lines:** 7  
**Files:** 1  
**Setup Time:** 1 minute

---

#### NEXIUM ✨
```python
from nexium import Nexium

app = Nexium()

@app.get("/")
async def home():
    return {"message": "Hello"}

if __name__ == "__main__":
    app.run()
```
**Lines:** 8  
**Files:** 1  
**Setup Time:** 30 seconds

**Winner:** NEXIUM (as simple as FastAPI, but batteries included!)

---

### CRUD API with Database

#### Django
```python
# models.py
from django.db import models

class User(models.Model):
    name = models.CharField(max_length=100)
    email = models.EmailField()
    age = models.IntegerField()

# serializers.py
from rest_framework import serializers

class UserSerializer(serializers.ModelSerializer):
    class Meta:
        model = User
        fields = ['id', 'name', 'email', 'age']

# views.py
from rest_framework import viewsets

class UserViewSet(viewsets.ModelViewSet):
    queryset = User.objects.all()
    serializer_class = UserSerializer

# urls.py
from rest_framework.routers import DefaultRouter

router = DefaultRouter()
router.register(r'users', UserViewSet)

# + settings.py configuration
# + migrations (python manage.py makemigrations)
# + database setup
```
**Lines:** ~100+  
**Files:** 5+  
**Dependencies:** Django, DRF

---

#### FastAPI
```python
from fastapi import FastAPI
from pydantic import BaseModel
# No ORM included, need to add SQLAlchemy/Tortoise

app = FastAPI()

class User(BaseModel):
    id: int
    name: str
    email: str
    age: int

# Manual database connection
# Manual CRUD operations
# No built-in ORM

@app.get("/users")
async def list_users():
    # Manual query
    return []

@app.post("/users")
async def create_user(user: User):
    # Manual save
    return user

# Need to install and configure:
# - SQLAlchemy OR Tortoise ORM
# - Alembic for migrations
```
**Lines:** ~200+ (with ORM setup)  
**Files:** 3+  
**Dependencies:** FastAPI, SQLAlchemy, Alembic

---

#### NEXIUM ✨
```python
from nexium import Nexium, Model, validate, Field

app = Nexium()

# ORM built-in!
class User(Model):
    __table__ = "users"

@app.get("/users")
async def list_users():
    users = await User.all()
    return [u.dict() for u in users]

@app.get("/users/{id}")
async def get_user(id: int):
    user = await User.get(id=id)
    return user.dict() if user else {"error": "Not found"}

@app.post("/users")
@validate
async def create_user(
    name: str = Field(min_length=3),
    email: str = Field(pattern=r"^[\w\.-]+@[\w\.-]+\.\w+$"),
    age: int = Field(ge=18)
):
    user = User(name=name, email=email, age=age)
    await user.save()
    return user.dict()

@app.put("/users/{id}")
async def update_user(id: int, name: str, email: str):
    user = await User.get(id=id)
    user.name = name
    user.email = email
    await user.save()
    return user.dict()

@app.delete("/users/{id}")
async def delete_user(id: int):
    user = await User.get(id=id)
    await user.delete()
    return {"message": "Deleted"}

if __name__ == "__main__":
    app.run()
```
**Lines:** ~35  
**Files:** 1  
**Dependencies:** Just NEXIUM!

**Winner:** NEXIUM (ORM, validation, routing, all in one!)

FastAPI:  📚📚 30-60 minutes   (docs, pydantic, async)
NEXIUM:   📚 10-20 minutes     (quickstart, done!)
```

### Lines of Boilerplate

```
Django:   ~500 lines   (settings, models, serializers, views, urls)
FastAPI:  ~50 lines    (models, database setup)
NEXIUM:   ~10 lines    (just write code!)
```
