Litestar Dependency Injection

Use this skill for Provide, NamedDependency / SkipValidation (Litestar ≥ 2.23), dependency maps, provider factories, request-scoped resources, and Dishka integration.

Code Style Rules

• Prefer NamedDependency[T] and SkipValidation[T] (≥ 2.23) over Annotated[T, Dependency()] / Dependency(skip_validation=True); params.Dependency is deprecated (removed in 3.0).
• Use Litestar dependency maps for simple and medium apps.
• Use Dishka when the project needs explicit scopes and provider modules.
• Keep provider names stable and descriptive.
• Do not open request-scoped resources at import time.

Quick Reference

• DI patterns: di.md
• Pair with litestar-data-services for service providers.
• Pair with litestar-settings for settings injection.
