Enforce end-to-end type safety in a large TypeScript codebase by applying advanced patterns like discriminated unions, branded types, and strict mode. This ensures compile-time correctness across complex domain models and APIs.

Design type-safe API contracts in TypeScript by applying type-first API design and tRPC-style patterns. This guarantees end-to-end type safety between frontend and backend, reducing runtime errors through robust compile-time validation.

Use TypeScript project references for monorepo architectures when you need scalable tooling and faster compilation times. They enable robust type checking across interdependent packages while maintaining strict boundaries.

Conditional types and mapped types improve complex generics by enabling dynamic, type-level logic. They allow you to create flexible, reusable type structures that enforce strong typing and handle evolving codebase requirements.

Yes, strict mode and the 'satisfies' operator are fully supported for type-first API design. They ensure robust error handling and exact type matching, allowing variables to satisfy specific constraints without widening their inferred types.

Use branded types and type guards for domain modeling in TypeScript to enable compile-time safety. They prevent invalid state assignments by creating distinct, verifiable types, ensuring robust validation across complex business logic.
