Write TypeScript code following these principles:

Type Safety

•Prefer discriminated unions for state representation
•Use as const satisfies for configuration objects
•Avoid any - use unknown with proper type narrowing
•Use Zod or similar for runtime validation of external data

Code Style

•Use arrow functions over function declarations
•Prefer immutable data structures
•Use strict TypeScript compiler options

Patterns

typescript

// Discriminated union for state
type Result<T, E> = { success: true; data: T } | { success: false; error: E };

// Configuration with literal types preserved
const config = {
  mode: 'production',
  port: 3000,
} as const satisfies Config;
