# API Reference

## Authentication Module

### `jwt_handler.generate_token()`

Generate a JWT access token for authenticated user.

**Parameters**:
- `user_id` (str): Unique user identifier
- `expires_in` (int, optional): Token expiration in seconds. Default: 3600

**Returns**:
- `str`: Encoded JWT token

**Raises**:
- `ValueError`: If user_id is invalid
- `TokenGenerationError`: If token creation fails

**Example**:
```python
from auth.jwt_handler import generate_token

# Generate token for user
token = generate_token(user_id="user_123", expires_in=7200)
print(f"Access token: {token}")

Security Considerations:

  • Store SECRET_KEY in environment variables
  • Use HTTPS for token transmission
  • Implement token refresh mechanism
  • Consider token blacklist for logout

### 4. Tutorial Generation

**Auto-generated from Code Patterns**:

```markdown
# Tutorial: Implementing JWT Authentication

## Overview
This tutorial will guide you through implementing JWT authentication in your FastAPI application.

**What you'll learn**:
- Generate and validate JWT tokens
- Protect API endpoints
- Implement refresh token mechanism
- Handle token expiration

**Prerequisites**:
- FastAPI application set up
- Python 3.11+
- Basic understanding of HTTP authentication

**Estimated time**: 30 minutes

## Step 1: Install Dependencies

```bash
poetry add pyjwt passlib[bcrypt]

Step 2: Configure JWT Settings

Create src/config/security.py:

from pydantic_settings import BaseSettings

class SecuritySettings(BaseSettings):
    SECRET_KEY: str
    ALGORITHM: str = "HS256"
    ACCESS_TOKEN_EXPIRE_MINUTES: int = 15
    REFRESH_TOKEN_EXPIRE_DAYS: int = 7
    
    class Config:
        env_file = ".env"

settings = SecuritySettings()

Step 3: Create JWT Handler

Create src/auth/jwt_handler.py:

from datetime import datetime, timedelta
import jwt
from config.security import settings

def generate_token(user_id: str, expires_in: int = None) -> str:
    """Generate JWT access token"""
    if expires_in is None:
        expires_in = settings.ACCESS_TOKEN_EXPIRE_MINUTES * 60
    
    payload = {
        "user_id": user_id,
        "exp": datetime.utcnow() + timedelta(seconds=expires_in),
        "iat": datetime.utcnow()
    }
    
    return jwt.encode(
        payload,
        settings.SECRET_KEY,
        algorithm=settings.ALGORITHM
    )

def validate_token(token: str) -> dict:
    """Validate JWT token"""
    try:
        payload = jwt.decode(
            token,
            settings.SECRET_KEY,
            algorithms=[settings.ALGORITHM]
        )
        return payload
    except jwt.ExpiredSignatureError:
        raise ValueError("Token expired")
    except jwt.JWTError:
        raise ValueError("Invalid token")

Step 4: Protect API Endpoints

Create authentication dependency in src/auth/dependencies.py:

from fastapi import Depends, HTTPException, status
from fastapi.security import HTTPBearer, HTTPAuthorizationCredentials
from .jwt_handler import validate_token

security = HTTPBearer()

async def get_current_user(
    credentials: HTTPAuthorizationCredentials = Depends(security)
) -> dict:
    """Extract and validate user from JWT"""
    try:
        payload = validate_token(credentials.credentials)
        return payload
    except ValueError as e:
        raise HTTPException(
            status_code=status.HTTP_401_UNAUTHORIZED,
            detail=str(e)
        )

Step 5: Use in Routes

Update src/api/routes.py:

from fastapi import APIRouter, Depends
from auth.dependencies import get_current_user

router = APIRouter()

@router.get("/protected")
async def protected_route(user: dict = Depends(get_current_user)):
    """Protected endpoint requiring authentication"""
    return {
        "message": "Access granted",
        "user_id": user["user_id"]
    }

Step 6: Test Your Implementation

Create tests/test_auth.py:

import pytest
from auth.jwt_handler import generate_token, validate_token

def test_generate_and_validate_token():
    """Test token generation and validation"""
    user_id = "user_123"
    token = generate_token(user_id)
    
    payload = validate_token(token)
    assert payload["user_id"] == user_id

def test_expired_token():
    """Test expired token rejection"""
    token = generate_token("user_123", expires_in=-1)
    
    with pytest.raises(ValueError, match="Token expired"):
        validate_token(token)

Next Steps

  • Implement refresh token mechanism
  • Add token blacklist for logout
  • Set up rate limiting
  • Configure CORS properly
