## About

# Litestar Settings

Use this skill for typed settings, env loading, cached settings factories, and app-state wiring.

## Code Style Rules

- Use dataclass settings plus get_env for fresh Litestar apps.
- Use pydantic-settings when the project already depends on Pydantic for config.
- Cache settings once per process.
- Keep secret values out of logs and generated docs.

## Quick Reference

- Settings patterns: [settings.md](references/settings.md)
- Pair with [litestar-di](../litestar-di/SKILL.md) for settings providers.
- Pair with [litestar-deployment](../litestar-deployment/SKILL.md) for runtime env wiring.

## Workflow

1. Inventory required env vars and defaults.
2. Choose dataclass settings or the existing Pydantic settings path.
3. Add a cached factory.
4. Inject settings through app state or DI.

## Guardrails

- Do not parse env vars repeatedly in handlers.
- Do not use msgspec Structs for env loading.
- Do not bake environment-specific values into code.
- Do not log secrets while debugging config.

## Validation Checkpoint

- [ ] Settings are typed.
- [ ] Settings are cached.
- [ ] Required values fail early.
- [ ] Tests can override settings without mutating global process env unexpectedly.

## Example

```python
from dataclasses import dataclass, field
from functools import lru_cache
from os import getenv

def get_env(key: str, default: str) -> str:
    return getenv(key, default)

@dataclass(frozen=True)
class AppSettings:
    name: str = field(default_factory=lambda: get_env("APP_NAME", "api"))

@lru_cache(maxsize=1)
def get_settings() -> AppSettings:
    return AppSettings()
```
