To create a type-safe API client, use TypeScript generics and conditional types to automatically infer request and response shapes based on endpoint definitions, preventing runtime errors.

The best way to transform existing TypeScript types into new shapes is by using mapped types and built-in utility types to modify properties without rewriting definitions.

TypeScript conditional types work by checking a type condition and returning different types based on the result, allowing you to create dynamic type logic and complex type inference.

You need template literal types in TypeScript when defining specific string patterns for type safety, enabling the creation of strict string-based APIs and complex type-safe routing.

To build reusable components that work with any type in TypeScript, implement generics to create flexible, type-safe components and libraries that maintain strict type inference across different data structures.
