SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This skill eliminates tedious, error-prone manual configuration of Litestar data transfer objects (DTOs) and mismatches between OpenAPI schemas and intended API contracts, reducing backend-frontend alignment work for Litestar developers.

Core Features & Use Cases

  • DTO Configuration Guidance: Provides best practices for selecting and configuring msgspec or Pydantic DTOs for request/response typing, including field exclusion, renaming, and partial update setup.
  • OpenAPI Contract Alignment: Helps validate that generated OpenAPI schemas match API behavior, including wire naming conventions and correct media type handling for request bodies.
  • Use Case: For example, when building a Litestar user management API, use this skill to configure write DTOs that exclude server-owned fields like id and created_at, and verify the /schema endpoint outputs the correct camelCase contract for frontend consumers.

Quick Start

Use the litestar-dto-openapi skill to configure a write DTO for your User model that excludes internal server-owned fields and matches your API's camelCase naming convention.

FAQPage Schema
How do I exclude server-owned fields like id from Litestar write DTOs?▼

To exclude server-owned fields from Litestar write DTOs, configure your DTO definition to omit fields like `id` and `created_at`, ensuring generated OpenAPI schemas and request bodies reflect only client-writable data.

How do I configure Litestar OpenAPI schemas to use camelCase wire naming?▼

Configure Litestar OpenAPI schemas for camelCase wire naming by applying field renaming rules to your DTOs, enforcing snake_case Python variables while outputting the correct camelCase contract for frontend consumers.

Can I use msgspec DTOs with Litestar for REST API request and response typing?▼

Yes, you can use msgspec DTOs with Litestar for REST API request and response typing, applying best practices for field exclusion, partial updates, and aligning generated OpenAPI schema validation.

What's the best way to validate OpenAPI contract alignment in a Litestar REST API?▼

The best way to validate OpenAPI contract alignment in a Litestar REST API is to verify that generated OpenAPI schemas at the `/schema` endpoint match intended API behavior, including correct media type handling and wire naming conventions.

Does Litestar support Pydantic DTO configuration for OpenAPI schema generation?▼

Yes, Litestar supports Pydantic DTO configuration for OpenAPI schema generation, allowing you to streamline data transfer object typing, field renaming, and API contract validation alongside msgspec alternatives.
