🔧 Building Crunchyroll Utilities

Create reusable utility functions for fetching episode data, parsing responses, and handling errors. Build a CrunchyrollClient class that encapsulates all API interactions.

📦 CrunchyrollClient Class

class CrunchyrollClient:
    """Reusable Crunchyroll API client."""

    def __init__(self, config, token: str):
        self.config = config
        self.token = token
        self.base_url = config.api_base
        self.episodes_fetched = 0

    def _get(self, endpoint: str) -> dict:
        """Make authenticated GET request."""
        url = f"{self.base_url}{endpoint}"
        headers = {
            "Authorization": f"Bearer {self.token}"
        }
        response = requests.get(url, headers=headers, timeout=10)
        if response.status_code == 200:
            return response.json()
        return None

    def get_episodes(self) -> list:
        """Fetch all watched episodes."""
        episodes = []
        try:
            data = self._get("/api/v2/episodes")
            if data:
                episodes = data.get('items', [])
                self.episodes_fetched = len(episodes)
        except Exception as e:
            print(f"Error: {e}")
        return episodes
        

💻 Coding Challenges

Challenge 1: Build CrunchyrollClient

Create class with __init__, _get(), and get_episodes() methods.

Challenge 2: Episode Parsing

Parse episode data to extract show name, episode name, date watched.

Challenge 3: Error Handling

Handle API errors, token expiration, network issues gracefully.
