How do I create a TypeScript type definition for a stateless React component?

After a lot of fiddling, we have settled on the following set up.

import React from 'react';

export interface MyComponentProps {
    prop1: boolean;
    prop2?: string;
    prop3?: string;
}

declare const MyComponent: React.SFC<MyComponentProps>

export default MyComponent

The inspiration for this was taken from:
https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/types/material-ui/index.d.ts

It works well with TypeDoc and also VS Code’s intellisense.

I believe export default was the key to cracking intellisense here.
