# Create a virtual environment
python -m venv venv

# Activate the virtual environment
# On Windows
venvScriptsactivate

# On macOS/Linux
source venv/bin/activate

# Upgrade pip
pip install --upgrade pip

### **2. Installing Dependencies**

Install the necessary Python packages.

pip install fastapi uvicorn sqlalchemy aiosqlite pydantic

- **fastapi:** The web framework for building APIs.
- **uvicorn:** ASGI server for running FastAPI applications.
- **sqlalchemy:** ORM for database interactions.
- **aiosqlite:** Asynchronous SQLite support.
- **pydantic:** Data validation and settings management.

### **3. Defining the Data Models**

We'll use `dataclasses` and Pydantic models for data validation and type hints.

# models.py

from dataclasses import dataclass
from pydantic import BaseModel, Field
from typing import Optional

@dataclass
class Score:
    id: int
    player_name: str
    score: int
    timestamp: str  # ISO format datetime string

class ScoreCreate(BaseModel):
    player_name: str = Field(..., example="Player1")
    score: int = Field(..., gt=0, example=1000)

class ScoreResponse(BaseModel):
    id: int
    player_name: str
    score: int
    timestamp: str

    class Config:
        orm_mode = True

### **4. Database Configuration**

We'll use SQLAlchemy for ORM and manage asynchronous database operations with `aiosqlite`.

# database.py

from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy import Column, Integer, String, DateTime
from sqlalchemy import create_engine
from sqlalchemy.orm import sessionmaker
import aiosqlite
import asyncio
from datetime import datetime

DATABASE_URL = "sqlite+aiosqlite:///./scores.db"

Base = declarative_base()

class ScoreTable(Base):
    __tablename__ = "scores"

    id = Column(Integer, primary_key=True, index=True)
    player_name = Column(String, index=True)
    score = Column(Integer, index=True)
    timestamp = Column(DateTime, default=datetime.utcnow)

async def init_db():
    async with aiosqlite.connect("scores.db") as db:
        await db.execute("""
            CREATE TABLE IF NOT EXISTS scores (
                id INTEGER PRIMARY KEY,
                player_name TEXT NOT NULL,
                score INTEGER NOT NULL,
                timestamp TEXT NOT NULL
            )
        """)
        await db.commit()

### **5. Creating the FastAPI Application**

# main.py

from fastapi import FastAPI, HTTPException
from typing import List
from models import ScoreCreate, ScoreResponse
from database import init_db
import aiosqlite
from datetime import datetime

app = FastAPI(title="3D Snake Game Backend",
              description="API for managing high scores in the 3D Snake Game",
              version="1.0.0")

DATABASE = "scores.db"

@app.on_event("startup")
async def startup_event():
    await init_db()

@app.post("/scores/", response_model=ScoreResponse, status_code=201)
async def create_score(score: ScoreCreate):
    """Create a new high score."""
    timestamp = datetime.utcnow().isoformat()
    query = "INSERT INTO scores (player_name, score, timestamp) VALUES (?, ?, ?)"
    async with aiosqlite.connect(DATABASE) as db:
        cursor = await db.execute(query, (score.player_name, score.score, timestamp))
        await db.commit()
        score_id = cursor.lastrowid
    return ScoreResponse(id=score_id, player_name=score.player_name, score=score.score, timestamp=timestamp)

@app.get("/scores/", response_model=List[ScoreResponse])
async def get_scores(limit: int = 10):
    """Retrieve top high scores."""
    query = "SELECT id, player_name, score, timestamp FROM scores ORDER BY score DESC LIMIT ?"
    async with aiosqlite.connect(DATABASE) as db:
        cursor = await db.execute(query, (limit,))
        rows = await cursor.fetchall()
    scores = [ScoreResponse(id=row[0], player_name=row[1], score=row[2], timestamp=row[3]) for row in rows]
    return scores

@app.get("/scores/{score_id}", response_model=ScoreResponse)
async def get_score(score_id: int):
    """Retrieve a specific high score by ID."""
    query = "SELECT id, player_name, score, timestamp FROM scores WHERE id = ?"
    async with aiosqlite.connect(DATABASE) as db:
        cursor = await db.execute(query, (score_id,))
        row = await cursor.fetchone()
    if row:
        return ScoreResponse(id=row[0], player_name=row[1], score=row[2], timestamp=row[3])
    else:
        raise HTTPException(status_code=404, detail="Score not found")

@app.delete("/scores/{score_id}", status_code=204)
async def delete_score(score_id: int):
    """Delete a high score by ID."""
    query = "DELETE FROM scores WHERE id = ?"
    async with aiosqlite.connect(DATABASE) as db:
        cursor = await db.execute(query, (score_id,))
        await db.commit()
        if cursor.rowcount == 0:
            raise HTTPException(status_code=404, detail="Score not found")
    return

### **6. Running the Application**

Use Uvicorn to run the FastAPI application.

uvicorn main:app --reload

- The `--reload` flag is useful during development as it reloads the server on code changes.
- Access the interactive API documentation at `http://127.0.0.1:8000/docs`

### **7. Cross-Platform Compatibility**

The provided Python code is cross-platform compatible as it relies on standard Python libraries and cross-platform packages like FastAPI and SQLAlchemy. Ensure that the environment has Python 3.7+ installed.

---

## **Code Explanation and Highlights**

1. **Asynchronous Operations with `asyncio`:**
   
   - All database operations are performed asynchronously using `aiosqlite` to prevent blocking the event loop, ensuring that the API can handle multiple requests concurrently.

2. **Type Hints and Data Modeling:**
   
   - Pydantic models (`ScoreCreate`, `ScoreResponse`) are used for request validation and response formatting.
   - The `ScoreResponse` model utilizes `Config.orm_mode = True` to allow compatibility with ORM objects.
   - Type hints enhance code readability and facilitate easier debugging and maintenance.

3. **Dataclasses for Internal Data Structures:**
   
   - While Pydantic models handle data validation, a basic `dataclass` (`Score`) is defined for internal use or potential future enhancements where plain data structures might be beneficial.

4. **Database Schema Initialization:**
   
   - The `init_db` function initializes the SQLite database and creates the `scores` table if it doesn't exist. This ensures that the database is ready to handle requests when the application starts.

5. **API Endpoints:**
   
   - **Create Score (`POST /scores/`):** Allows the game to submit a new high score.
   - **Get Top Scores (`GET /scores/`):** Retrieves a list of top high scores, limited by a query parameter.
   - **Get Score by ID (`GET /scores/{score_id}`):** Fetches a specific score entry using its unique ID.
   - **Delete Score (`DELETE /scores/{score_id}`):** Removes a score entry, which can be useful for moderation or cleanup.

6. **Error Handling:**
   
   - Proper HTTP exceptions are raised (e.g., `404 Not Found`) when attempting to access or delete non-existent score entries, providing clear feedback to API consumers.

7. **Documentation:**
   
   - FastAPI automatically generates interactive API documentation accessible via `/docs` (Swagger UI) and `/redoc` (ReDoc), aiding both development and integration processes.

8. **Security Considerations:**
   
   - For a production environment, consider implementing authentication mechanisms (e.g., API keys, OAuth) to protect the API endpoints.
   - Implement rate limiting to prevent abuse.
   - Use environment variables or configuration files to manage sensitive information like database URLs.

## **Testing the API**

You can use tools like **cURL**, **Postman**, or the interactive Swagger UI provided by FastAPI to test the API endpoints.

### **1. Creating a New Score**

curl -X POST "http://127.0.0.1:8000/scores/" -H "Content-Type: application/json" -d '{"player_name": "Alice", "score": 1500}'

### **2. Retrieving Top Scores**

curl -X GET "http://127.0.0.1:8000/scores/?limit=5"

### **3. Retrieving a Specific Score**

curl -X GET "http://127.0.0.1:8000/scores/1"

### **4. Deleting a Score**

curl -X DELETE "http://127.0.0.1:8000/scores/1"

---

## **Integrating with the Frontend**

Your JavaScript frontend can interact with this API to submit and retrieve high scores. Here's a simple example using the Fetch API:

// Submit a new score
async function submitScore(playerName, score) {
    const response = await fetch('http://127.0.0.1:8000/scores/', {
        method: 'POST',
        headers: {
            'Content-Type': 'application/json'
        },
        body: JSON.stringify({ player_name: playerName, score: score })
    });
    if (response.ok) {
        const data = await response.json();
        console.log('Score submitted:', data);
    } else {
        console.error('Failed to submit score');
    }
}

// Retrieve top scores
async function getTopScores(limit = 10) {
    const response = await fetch(`http://127.0.0.1:8000/scores/?limit=${limit}`);
    if (response.ok) {
        const scores = await response.json();
        console.log('Top Scores:', scores);
        return scores;
    } else {
        console.error('Failed to retrieve scores');
        return [];
    }
}

**Note:** For production deployment, ensure that the backend is hosted on a reliable server and that appropriate CORS settings are configured to allow the frontend to communicate with the backend securely.
