type-safe-monkey-patching

To add custom properties to the window object without using as any, use TypeScript interface augmentation. Define an interface that augments the global Window type, then assign typed values directly for safe global state management.

The best way to attach data to DOM elements while keeping type safety is using safe patterns for DOM manipulation. Define typed interfaces for your DOM data and apply safer type assertions instead of relying on unsafe monkey patching.

To migrate legacy code from unsafe monkey patching, replace runtime modifications and as any casts with interface augmentation. Enforce structured approaches for shared global state and per-element data to restore type safety.

Monkey patching global objects breaks TypeScript type safety because it modifies runtime objects outside their defined interfaces. This forces developers to use unsafe type assertions like as any, bypassing the compiler's type checking.

Yes, you can safely augment the Document interface for DOM-related globals in TypeScript. Interface augmentation allows you to model runtime modifications on document or DOM nodes while enforcing type safety and avoiding loose typing.
