Contract-first API design establishes interface standards and response field conventions before coding, ensuring stable boundaries. It is essential for building robust REST APIs and module interfaces that require consistent validation and error handling.

To design REST APIs in TypeScript, apply consistent error handling and boundary validation using established interface patterns. Structure resource endpoints, query parameters, and response fields by following standardized naming conventions and validation rules.

Best practices for REST API pagination and filtering involve applying consistent interface patterns across resource endpoints. Standardize query parameters and response field structures to ensure robust partial updates and predictable data retrieval.

Yes, TypeScript knowledge is required to apply these API design standards effectively. The interface patterns and validation conventions rely heavily on TypeScript to enforce stable module boundaries and consistent API contracts.

Yes, these interface design standards apply to GraphQL schemas as well as REST APIs. The core principles of contract-first development, boundary validation, and consistent error handling translate directly to structuring robust GraphQL interfaces.
