TypeScript with Type Stripping

When writing TypeScript for Node.js, use type stripping (Node.js 22.6+) instead of build tools like ts-node or tsx. Type stripping runs TypeScript directly by removing type annotations at runtime without transpilation.

Key requirements for type stripping compatibility:

• Use import type for type-only imports
• Use const objects instead of enums
• Avoid namespaces and parameter properties
• Use .ts extensions in imports

Minimal example — a valid type-stripped TypeScript file:

// greet.ts
import type { IncomingMessage } from 'node:http';
