To build a type-safe API client, use TypeScript generics and conditional types with the infer keyword to extract and enforce request body, params, and response shapes from a route-to-method configuration object at compile time.

Conditional and distributive types in TypeScript express branching type logic, allowing you to infer results from other types and automatically apply type narrowing across union members to enforce strict compile-time rules.

Mapped types with key remapping transform existing object types by iterating over their keys and applying template literal types to generate new, pattern-based string types for safer APIs and configuration objects.

Use TypeScript template literal types when you need to generate pattern-based string types, enabling strongly typed event systems and configuration objects by enforcing specific string formats at compile time.

Yes, you can build discriminated union state machines in TypeScript by applying advanced type utilities and conditional types to enforce valid state transitions and complex object shapes at compile time.

TypeScript requires generics to write reusable, strongly typed abstractions because they allow you to define constraints and multiple type parameters that maintain strict type inference across different application layers.
