App Setup

Use this skill when the user needs to create a new Litestar app, structure an existing app, or configure core application settings.

Workflow

1. Define a minimal Litestar(...) app and register route handlers.
2. Move handlers into routers as complexity grows.
3. Add app-level configuration (debug, openapi_config, logging_config, dependencies, middleware).
4. Add lifespan hooks for startup/shutdown needs.

Minimal Pattern

from litestar import Litestar, get

@get("/health")
async def health() -> dict[str, str]:
    return {"status": "ok"}
