But how did you get rid of the implicit anys when using JSX?

I used this compiler flag that forbids them and suddnendly nothing worked anymore. It seemed that almost everything returned any per default.

I use these typings: https://github.com/DefinitelyTyped/DefinitelyTyped/blob/mast...

Then create my components like this:

interface Props {

}

interface State {

}

class MyComponent extends React.Component<Props, State> {

}

and everything is typed correctly (beside setState which is impossible to type exactly as of today)

function MyComponent(props: IMyComponentProps): JSX.Element { return <p>{props.x}</p>; }

  interface Props {
    bla: string
    ble: number
  }

  export default function MyComponent({ bla, ble }: Props) {

  }
