How do you explicitly set a new property on `window` in TypeScript?

Question

I setup global namespaces for my objects by explicitly setting a property on window.

window.MyNamespace = window.MyNamespace || {};

Answer 1

I don't need to do this very often, the only case I have had was when using Redux Devtools with middleware.

I simply did:

const composeEnhancers = (window as any).__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ || compose;

Or you could do:

let myWindow = window as any;

and then myWindow.myProp = 'my value';
